Yes, shark cartilage supplements carry risks, but so do many cancer treatments. The question is does it work?

When it comes to marketing “unproven cancer treatments,” “the Internet has become the Wild West. Fraudsters are…able…to take advantage of people” like never before. “Cancer Patients Find Quackery on The Web”, bemoaned the National Cancer Institute. Did you know there were “[m]ore than 200,000 documents about cancer…on the…Web”? What? When was this published? Oh, 1996. That’s just a few years after the web was born. Not to worry, though, said the author of Dr. Linden’s Guide to Online Medicine, “it takes a lot of time and money to maintain a Web page.” So, don’t worry, “the mass of information on the Internet will dwindle during the next few years as the Internet matures.”

Riiiiight. Yes, dwindling from 200,000 down to a mere, you know, nearly a quarter of a billion. And, one of the most commonly recommended quote-unquote “alternative cancer cures” on popular websites is shark cartilage.

“Much has been made in recent years of the mystical aura afforded [to the stuff]. Clearly, part of [it is the] visceral fear of cancer combined with a healthy respect for a creature [who] has survived [basically unchanged since] prehistoric times. It has been reported that sharks rarely get cancer,” and their skeleton is made out of cartilage, and so, “[l]ogic has led some to believe that this must be the reason for sharks’ relative health.” Not exactly sure that’s logical, but they do have a lot of cartilage. Cartilage, in general, has few blood vessels, and blood vessels are important for cancer growth, and all this “conspired to prime fraught [cancer] patients for shameful exploitation by pseudoscience and the supplement industry with the addition of just one myth”—that “sharks don’t get cancer.” But, they “do get cancer” after all. Just another “layer…of fallacious arguments,…successfully convinc[ing] desperate cancer patients to buy ineffective products.” But wait, you don’t know if it’s ineffective, until you put it to the test.

Sixty patients with a variety of advanced cancers were given like a dozen scoops a day of shark cartilage, and…not a single, even partial, response was noted in any of their tumors. Ineffective with “no salutary effect on [the] quality of life.” In fact, they suffered significant gastrointestinal toxicity from the stuff, all the while the tumors progressed in all the patients. But what’s missing from this survival graph? What happened in the control group? There was no control group. So, while this is what you’d expect to see in advanced cancer patients, how do we know the cancers wouldn’t have progressed even faster without the shark cartilage? That’s why we need randomized, controlled trials, but there weren’t any, until the Mayo Clinic stepped up. “[A]…randomized, placebo-controlled, double-blind, clinical trial [for] [p]atients with incurable breast or colorectal carcinoma.”

“Data on a total of 83…patients [was] analyzed. And? “There was no difference in…survival between patients [getting]…shark cartilage…versus [those getting] placebo”—nor any “suggestion of improvement in quality of life.” And, there was evidently a prostate cancer study, too. Only five patients were even able to complete the study, and, in all five, their cancers continued to progress unabated. So: “Unfortunately, the claims for the benefits of shark cartilage are completely unsubstantiated by any objective data from controlled clinical trials.”

Not so fast, said supplement manufacturers. Maybe these crude commercial shark cartilage powders just don’t have high enough levels of whatever active components there may be. So, cancer patients should instead be taking shark cartilage extract pills. So, the National Cancer Institute said fine, we’ll test that too, just to make absolutely sure. And so, they funded a randomized, double-blinded, placebo-controlled trial to put it to the test.

Unlike the other shark cartilage dietary supplement studies, they used the purified extract, and “the study outcome [was] unambiguous.” It failed. The shark cartilage group lived 14 months, and the placebo group lived 15 months. So, no significant difference in survival or time to progression or tumor response rate. So, “[t]hese clinical studies [suggest] shark cartilage is not just [an] unproven…cancer remedy, [but actually a] well disproven [one].” Yet, “[d]espite [the] overwhelming evidence to the contrary, such claims persisted. For example, the huckster who started it all wrote a sequel, Sharks Still Don’t Get Cancer. Perhaps “[t]he only cure for this myth is to spread the rumor that cartilage from the noses of [such] quacks [fights cancer too].”

Anyway, if you really wanted to eat angiogenesis inhibitors, why sit down to a bowl of cartilage powder, when you could just eat an apple, or drink green tea, or turmeric, or pomegranate berries and nuts, soybeans, flax seeds, or broccoli—all of which have been shown to have anti-angiogenic effects.

  1. Several years ago, I ran across this research paper listing many plant foods that are not only anti-angiogenic, but also fight cancer in other ways. After listing the phytonutrients and the foods containing them, the paper goes on to explain how they work.

    https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4017674/

    The paper lists 18 different phytonutrients and the foods that contain them. Many of the nutrients and foods listed have been talked about by Dr Greger in previous videos on this website. And I would think there are many undiscovered nutrients in plant foods that haven’t even been discovered and named yet!

    Hope this helps shed some light on how plant foods are so healthful!

    1. Mark chondroltin is most commonly used for joint aid not cancer. And it is sometimes made from bovine and pig source not exclusively from shark.

      Glucosamine is not the same substance. They are marketed together often with MSM in one pill as all three are thought to aid with joint problems.
      MSM and glucosamine are both available in vegetarian form. But glucosamine when not vegetarian, is often made from chickens.
      If one is taking glucosamine a possible caution is sodium load, some types provide significant amounts. Other brands do not.

  2. Thank you Dr. Gregor for presenting this video. My concern is that with all the hoopla about shark cartilage, and how people who do not see this video will continue to exploit these creatures of the sea. They have to KILL sharks to obtain the cartilage and this has been going on probably for at least 100 years. This reminds me of the current situation with elephants. How do you think ivory objects that are sold on the open market are produced especially if the ivory is genuine. They Kill the elephants. So with continual slaughter of sharks it will eventually,and it is happening now upset the balence of the sea and cause all sorts f havoc in terms of upsetting the delicate balence of nature in the oceans. This myth about cancer cure must be dispelled to save the shark population. Unfortunately their are a lot of people who do not understand this video who will continue to exploit sharks for they own selfish means. It is these groups of people who need to sit down and be told about the plight of the shark.

    1. Sharks don’t tend to have the same advocacy on their behalf.

      People are more afraid of sharks than elephants.

      Also, there aren’t shark graveyards to post photos of.

      Hard to generate compassion for them.

      There aren’t Free Willy movies on their behalf.

      Just Jaws and Shark Week and stories of people getting bitten.

      You don’t hear stories like when the Greenpeace woman got people who hunt whales to save a family of gray whales.

      They did a movie about it and it was that people “humanized” the whales and “identified” with them.

      Shark stories are these horror stories, except for the surfer girl, who was back surfing so quick that it didn’t have as much “fear generating” effects.




      3
      1. Also, the researchers on sharks have emphasized the wrong things.

        One man who had a theory that people were getting attacked, because of their colorful swim gear who dressed in black and stood very still in the middle of sharks to show that they wouldn’t bite him, but one of them bit his calf…. So, he had surgery, but still wasn’t sure if his theory was wrong, so he came back to test the same theory again, which was about when I switched the station.

      2. Deb the concern with sharks is their threat of extinction. Just to mention.
        Per Wikipedia…”Shark species are increasingly becoming threatened because of commercial and recreational fishing pressures, the impact of non-shark fisheries on the seabed and shark prey species, and other habitat alterations such as damage and loss from coastal development and marine pollution.[6] Rising demands for shark products has increased pressure on shark fisheries, but little monitoring or management occurs of most fisheries.[7] Major declines in shark stocks have been recorded over the past few decades; some species have declined over 90% and population declines of 70% are not unusual

        I think ten species are listed as critically endangered. The US has actually done a good job on working to prevent that sponsoring things globally. The bad side globally in this is China and Japan who want no restrictions generally.
        Australia strangely enough is setting off explosives and killing large sharks to protect human swimming grounds…..
        so we could say globally there is diversity of opinion on this.

        There is a documentary movie on this but forget the name.

  3. Hooray for the researchers!

    Boo for the flim flam people on the internet!

    The word, “Laetrile” passed in front of the screen for a few seconds.

    Were there double blind studies for that?

    I didn’t try it, but lots and lots of Cancer patients are trying it with things like Gerson Therapy.

    I know that people like Chris from Chris Beat Cancer have taken it for years without ill effects and I saw a Mexican Clinic, which said they used it with thousands of people.

    Not saying that as a plug for it.

    Lots of things do nothing at all and I did choose the super hero super foods myself.

        1. And I mean that.

          You even reading these comments and helping us understand things.

          I do understand the value of a doctor’s time.

          Sometimes, I don’t think people on-line have a sense of that value about anyone, as if everyone should be volunteers at their whim.

          I hand out videos of life-saving topics from you every single day and the people are genuinely paying thousands of dollars to doctors who don’t tell them anything and I am on-line with a doctor who “takes house calls”

          You are a heroic figure in this.

          WFPB needs super hero comic books with Dr. Greger on his treadmill action figures.

      1. Hey doc…I’m pretty sure Steve McQueen was going for laetrile treatments in Mexico back in the day…check it of course if he really was….could be media misspeak or made up things….

        But how better to get click bait then a photo of him as the lead in?? Classic Steve M…him in that mustang.
        If you want more views and that rumor is true. He died of a heart attack but was being treated for asbestos related lung cancer exposed as a mariner on ships in his youth it was thought.

        1. In regards to Steve Mc Queen

          go here https://thetruthaboutcancer.com

          For FDA being the good guys go here

          https://herbhealers.com See book by Greg Caton The joys of Psychopathology..He knows having spend yrs in jail courtesy of corrupt FDA officials and being kidnapped from Ecuador illegally by FBI to be resent back to jail…to finish his sentence for parole violations with complicity of corrupt court system in New Orleans…!

          If you still believe in Quackwatch,FDA,CIA being the good guys etc.. your choice..a.

          I am from Canada and our system is as corrupt as yours except it is more underwraps…and Canadians being too complacent- all the European pop being replaced and majority of 3rd worldlers by 2030 and they do not come from democractic countries if you get my point-they (those here) and newcomers following dutifylly orders for the corrupt govvernmental officials and try to replicate corruption rings over here-it is their way of life-this is normal for them..
          Canada is hell bent towards socialism- think California to the nth degree… differences in main parties-like liivng in Russia-Cuba-Venezuela and China..Not much of a great choice ,isn’t it !

          I am in Ca

            1. OKAY TO THE ??? to be polite….

              If you believe that politicians,journalists,bankers on Wall Street all are 100% honest Joes and the Roman Catholic CHURCH and never lied,twisted facts or hidden pedophile priests…

              MAJORITY OF SUPPLEMENT MANUFACTURERS have been bought in the US by BIG PHARMA as well as in CANADA.

              And yes I have seen a degradation of the ingredients in the supplements – diminishing doses of elements,replacing effective ones by cheaper ones or being banned by Health Canada..

              My comment on this-Wikipedia does lies,so do Google is censuring unconventional news etc..or bury them

              I am using Duckdudckgo but even here it has gone down the tube as well..

              Shark Cartilage-manufacturers are allowed to state that it can relief Arthritis symptoms.

              The only thing that cannot be stated is all that is related to cancer-this for all related natural products…which includes Shark Cartilage

              We do have the pendants of Quackwatch in Canada it si called https://skepticnorth.com notice that their articles are dated.

              HINT-All SKEPTIC websites tend to use DATED filtered news-this is how they operate.No,they are not just uninformed-most of them do have vested interests,hidden agendas ? – I did meet some of them in the past.I was unimpressed and appalled at their blatant stupidity..

        2. I remember all this laetrile/amygdalin/vitamin B17 stuff being discussed here before. Someone raised it in the comments I think – no video as such.

          It’s another alternative health “suppressed cancer cure” myth that was exposed years ago. The US National Cancer Institute has had a page or two on this stuff for some years now.
          https://www.cancer.gov/about-cancer/treatment/cam/patient/laetrile-pdq

          Basically, clinical trials have shown no effects. Of course, you can find testimonials for it online. You can find enthusiastic textimonials online for virtually anything. Testimonials are worthless on their own.

          Lots of people eat apricot kernels for their supposed amygdalin content and anticancer effect. This is dangerous however. People can and do die from eating too many. However, in the US, people tend to eat sweet apricot kernels and these are perfectly safe. They also contain no or very litlle amygdalin/B17/laetrile. The bitter apricot kernels though do contain significant amounts of amygdalin/B17/laetrile and thiose are the ones that can be toxic if you eat too many of them. The people who promote these things don’t seem to understand this and/or have never evn reserached the topic. Either that of they are selling stuff and don’t really care about the facts in the first place.

          For all the complaints about the conventional cancer industry from alternative health advocates, it is ironic that some of the most ruthless and mendacious exploitation of the sick and dying for personal profit is practised by the alternative cancer cure “heroes”. Tweedle Dum and Tweedle Dee

          As for Chris Beat Cancer, here are a couple of sceptical viewpoints

          https://sciencebasedmedicine.org/chris-beat-cancer/
          https://rationalwiki.org/wiki/Chris_Beat_Cancer

          Marketing hype can kill when it comes to health and diet. Caveat emptor and “if it sounds too good to be true, it probably is” may be cliches but they are still sound advice.

            Hi.again I am no scientist but HATE hype and untruths.Unfortunately it is now very hard to discern what works and does not work

            I have been on the NET since 1993(before the WWW).Over the yrs I have seen pertinent infos disappeared or erased by Google and other similar fiends.Wikipedia-they have an agenda-even people they diss in articles cannot rectify the facts.

            Chris Beat Cancer- he has produced series of webinars into videos since 2015 and have a look at them- a plethora of doctors,scientists ,etc and yep all believed in benevolent big Pharma and saw the truth especially those that were able to cure their cancer via non orthodoxic means..

            Note here-he is VERY conventional in his approach-he will not talk publicly about”very unconventional cancer” et al treatment.To put it bluntly- he was given a choice-do your stuff within the set up parameters or a nice coffin is in your near future and that includes your family too.
            Journalists have an adept paraphrase when citing sources from politicians = “off the record”.

            But if you are convinced that Big Pharma,FDA,Quackwatch etc are all benevolent entities that want to help us well to each ITS OWN.AS FOR ME,NO THANKS..

            * I always try do due diligence- I try to go to the sources,not the hearsays,paid marketing journalists etc..*

    Hi,excellent video as always

    However Shark Cartilage night be useful for other ailments.I did take some in the past(1 btl)
    and it did help detoxify me and clean my intestines…

    I am wondering if any of them luminaries ever considered he followings:

    1- what type of diet where these patients doing ?

    2-where some taking other supplements/herbs etc ?

    3-Where some of them still getting radiation/chemo while still taking shark pills/powder ?

    4-what was the concentration of said shark pils/powder being taken ?

    5-And what kind(family/classes of sharks where these pills taken from ?

    I would appreciate it if you could read the updated version of the book-it would help.
    And yes ,supplement industry has been corrupted and taken over by Big Pharma.

    6-Oops find this original article by Dr Lane and he seems to have
    This article debunks current myths about being unscientific(a Canadian org)
    It is in vol 18,issue 3,May 1995)
    https://consumerhealth.org

    In 2004 the pure US FDA destroyed the company with fines,physically destroyignthe
    the product(Benefin,Skin Answers,MGN-3) etc..

    This is standard FDA/Big Pharma modus operandi- destroy a work product and then let
    the crooks flood the market with useless ones while the FDA looks the other way..

    UPDATED interview with Dr Lane is here:
    https://healthynet.com

    Dr Lane being interviewed by Ruichard Passwater,PhD-biochemistry(updated interview)
    Thus since that time we have useless “hark products er I mean supplements”

    https://consumerhealth.org
    YOURS,REY

    ADDED NOTE-very little trustworthy verification being dome for any supplements
    except when the FDA wants to find anything to ban a substance that works.

    Many of said scientific papers get funds from Big Pharma via their charitable
    foundatons,speciied grants to “dis”prove certain natural remedies,etc..

    1. I find the FDA’s overseeing of the supplement industry marginal at best.
      From their website on their scope of responsibility..
      FDA regulates both finished dietary supplement products and dietary ingredients. FDA regulates dietary supplements under a different set of regulations than those covering “conventional” foods and drug products. Under the Dietary Supplement Health and Education Act of 1994 (DSHEA):
      Manufacturers and distributors of dietary supplements and dietary ingredients are prohibited from marketing products that are adulterated or misbranded. That means that these firms are responsible for evaluating the safety and labeling of their products before marketing to ensure that they meet all the requirements of DSHEA and FDA regulations.
      FDA is responsible for taking action against any adulterated or misbranded dietary supplement product after it reaches the market.

      They must register the products state contents and this and that but pretty much this is it as I read it.

      On your various questions some are answered in the video.Special diets..no that would hamper the study result. Suspension of cancer fighting chemo and such…no that would hazard the patients. Study was used with normal shark C and a special shark C preparation.

      What are you getting at…do you think they work….prove it. Show you study that proves it and is a valid study. A book does not qualify.

          Humm- since 1st link an ole text -you have to replace the “https” with”
          http”. Https is the new standard now but many websites have not upgraded yet.In addition Firefox(v5.9+ will not link you to an “http” website.

          Best method is to Google or duckduckgo etc… it enter the text.still very surprised that many people nowadays cannot figure out if an error-full copied urlinks especially old ones- not that accurate nada and supplement companies are allowed to make claims on their bottles.

          The author- has been doing clinical trials in Mexican clinics.He also did some works in Cuba as well

          The FDA is indeed an evil organization-they put out of business companies that sell working products and let the crooks continue selling falsifying not working products and after a few years very hard to figure anything out…

          I am in Canada and companies are still allowed to put health benefits onto their products

          Yours,rey

          PS – Search Greg Caton https://herbhealers.com He also has a book “the Joys of Psychopathocracy

          If you go by wiki disinfo pedia well….they have an agenda…

          +90% of supplements sold in the US contaminated(most coming from China,India).wrong labelling,deceptive claims etc..best thing go via NOW- they are basically honest and do verify their products

          https://naturalnews.com (hyped products but clean and safe)..Also many small herbal companies do exist and most companies from Utah(Mormon country) have a good reputation.
          Latest misdeeds from FDA et al- the pot-cannabis pills etc..+90% junk being sold etc..see naturalnews.com and all done on PURPOSE as big Pharma is entering the filed with their GMO cannabis/synthetic derived cannibinoids,etc..

    2. This is all just a great big wordy story to try and justify sales of a product that all the evidence is worthless.

      And yes throw in the usual conspiracy theory explanation for why all the evidence shows that it is ineffective.

      You are supposed to check your tinfoil hat at the door when you enter this website. That is why it is called Nutritionfacts not “NutritionBS and here are thousands of worthless supplements, therapies and other scams you can buy”

    3. Ah, yes, Richard Passwater “PhD” – I don’t think so

      https://www.quackwatch.org/04ConsumerEducation/Nonrecorg/bernadean.html

      As for Dr Lane himself

      “Potential consumers, however, should be aware that the effectiveness of shark cartilage has not been demonstrated scientifically. They should also know that although I. William Lane is popularly known as “Dr. Lane”, he has a Ph.D. in agricultural biochemistry rather than a M.D. Also, he was a vice-president at W.R. Grace, which is an important defendant in many asbestos cancer lawsuits.

      Potential consumers should also be aware that, in December 1999, the U.S. Department of Justice filed a lawsuit against Lane Labs-USA and Andrew Lane (its president and the son of I. William Lane) in the U.S District Court for the District of New Jersey. The FDA sought to stop them from marketing shark cartilage with claims that it is an effective cancer therapy.”

      Also, what about “follow the money”? Lane has a serious finacial conflict of interest here. Frankly, i wouldn’t regard either of these two characters as credible.

    4. Rey, could you please not “detoxify” and “clean your intestines” at the expense of the planet and all life on it by taking the magical pills of cruelly slaughtered endangered wildlife? That’d Be great. Meanwhile, broccoli for one out of a sea of examples, will ACTUALLY detoxify you and clean your intestines among other things.

      1. Yep aware of broccoli BUT main problem in US- bigger is always betterYou have to b careful before stuffed yourself with “ultimate-concentrate powders/pills” some claim take this and = 15 stems of broccoli etc..

        It is well know by serious natural health practitioners that caution must be used..

        Having said that- same goes for Shark Cartilage-what do these supplements in fact contain-those sold in the US ?

        Problem with advocates of scientism(new religion) they have unababated faith in Science.Big Pharma etc..

        Ex ,yes essentials oils do work but I would not take then orally as too many practitioners do..
        Homeopathy/Bach Flowers remedy do work

        ???-Attention skeptics here- if you are full of anti-biotics,stuffed by OTC pills.etc chances of homeopathy/Bach Flowers working right out of the box are VERY SLIM.

        Best way to detoxify naturally- if following a Keto diet which is the modern term for fasting..

        So how about finding out what type of Shark Cartilage are being usedat the Mexico clinic

        Note-apparently an unwritten rule is that all Mexican cancer clinic cures that do work must be situated a telast 500 miles from any US frontier.Thus the plethora of clinics that are at Tijuana,well..

        However some clinics do a turn around- patients go there to be examined then they are sent to somewhere in the Caribbeans.Real sustainable trials are also conducted even in S. America like in Brazil as well,etc..

        Conclusion,no clear cut answers but if a clinic do hyped marketing on the net..humm….

        1. This is just a statement of belief and devoid of anything so mundane as actual evidence.

          it does however fit very well with a belief in conspiracy theories, Conspiracy theories are absolutely necessary because how else are you going to explain the lack of credible evidence supporting these beliefs?

          Just one point of detail, it is not a choice between believing either Big Pharms or the gang of conartists and cranks promoting false cures and fad diets. That is an entirely false dichotomy but one that has been suv=ccessfully used by snakeoil merchants for decades

        2. Wow Rey, you’re really complicating vegetable consumption. Broccoli pills aren’t necessary and probably at best, do nothing. If you want concentrated sulforaphane for example, just eat broccoli sprouts. But broccoli was just an example. Plant foods in general detoxify and are both protective and curative of pretty much all our biggest killers. The most cancer protective thing we can do is to eat a diet made up of whole plant foods whereas animal products on the other hand promote cancer in various ways.

          Given all the science on what we already know works against and know causes cancer, turning to shark cartilage is absolute idiocy at its very best. But worse than that, it is grotesque selfishness… Truly disgusting and shameful to say the absolute least.

          Why would anyone want to harm others and destroy the oceans and thus planet, for any reason even if it worked, but it’s especially gross to me because there are already proven solutions and none of them require any harm to other animals or the planet..

          Is it just not as spectacular to people to hear that plant consumption is the proven solution? It seems like people want a ridiculous story sometimes…

          1. Yep.I have started to eat sprouts and it has helped reduce my intake of supplements

            I no longer eat any GMO food.try to gert certified organic foods(prices are comign dow so becoming very affordable toa large degree

            Incidentally the 2018 Revolution Food Summit is starting tomorrow-free registration

            https://foodrevolutionsummit.org

            Also Ty Bollinger https://truthaboutcancer.net had an excellent series in regards to Pets and Cancer..
            No magical thinking here-just facts…If anyone has pets it is worth listening(I do not have any pets)

            Shark CARTILAGE-LAETRILE + …remember naysayers ALWAYS seem to have a VESTED INTEREST-so who are behind them. Seek the $$$ funds behind them truthers and you will get the real facts..

            VERY GOOD INFOS about the high/lowdown of what Shark Cartilage is all about.It is VERY COMPLEX.

            For the naysayers- in Canada- you can claim it provides relief for arthrities,skin disorders,etc..

            So go to this website https://lloydwright.org/2006/info/Cartilade_Shark_Cartilage.htm

            Now if you click at the end it will take you to his NEW website

            You will notice how unfree the Net has become since 2006

            Certain links disabled on account of FDA etc…no doubt…

            https://alternativemedicinesolution.com

            LAETRILE STUFF go here https://worldwithoutcancer.uk Now if you freak you because they have ads about said products and go on a quackquack fit..
            how about taking a valium or tow to begin with !

  5. I don’t get why Dr. Greger is working so hard to kill a dead horse. I listen to probably 20 or 30 holistic doctors talk about anti-cancer strategies and they mention the fruits and vegetables, but I haven’t heard any of them talk about shark cartilage since the 1990’s. Many of these documents are outdated from that era as well. I listen to Dr. Greger regularly and it has greatly affected my life for the better. I just don’t understand why he is fighting something that was decided long ago.

    Big Pharma is telling people to forget about food-it doesn’t matter, yet he doesn’t seem to be taking on Big Pharma’s big patented 3 of chemo, radiation and surgery, despite their ineffectiveness. Try dealing with actual current conflicts instead of tilting windmills or dragons.

    1. I am not so sure John. People are still selling this stuff and there is evidence that it may actively harm people

      “Shark cartilage, which has been hyped as a cancer preventive and joint-health supplement, may contain a neurotoxin that has been linked with Alzheimer’s and Lou Gehrig’s disease.

      Scientists at the University of Miami analyzed cartilage samples collected from seven species of sharks off the coast of Florida. The specimens all contained high levels of a compound called beta-methylamino-L-alanine, or BMAA, which has been linked to the development of neurodegenerative diseases. Sharks accumulate the compound because of their status at the top of the oceanic food chain, consuming fish and other sea creatures that feed on BMAA-containing algae. The small tissue samples were obtained from sharks that were caught, tagged and released for tracking research, and no sharks were harmed for the study.

      The findings are important because of the growing popularity of supplements that contain cartilage from shark fins. ”
      https://well.blogs.nytimes.com/2012/03/08/shark-cartilage-may-contain-toxin/

      And this article from Fortune last year suggests that the myth is still active. And Rey’s comments suggest that tere are stil people around who choose to believe these claims.

      1. Yes TG and there are peoples who believe California and Canada to be socialist states as well..;)

        I think this video would little tend to affect those who believe in things in this manner.
        That said to add as you probably know..Lou Gehrig was known conspicuously for one other recreational pursuit other than baseball….fishing. He was quite a avid fisher engaging it at every opportunity they say. We can assume back in that day he did eat his catch.

        Peoples really have to be careful when they engage supplements in the regulatory framework of the US. FDA oversite has in the actual be absent since Orin Hatch succeeded with his legislation way back in the 90’s. They pursue only absolute frauds the industry largly regulates itself.
        How many supplements are found on testing to have none of their claimed content….quite a few. Shark extract we can assume is the same.
        And if it does as you mention the substance itself may be in question if not overtly harmful.

    1. Jenn this is certainly a misuse of a animal but probably the single most intentional cause of shark killing is for shark fin soup. Shark fin soup is very popular in asia but also very expensive. But with the increased wealth in asia, China’s disposable income increase per person has exceeded ours for at least a decade each year…more is the demand. Typically they rip the fins off the sharks and throw them back to die. The meat of shark is occasionally harvested as well but it tends to spoil quickly and produce urea and contaminate other fish in storage. So usually they just keep the fins.
      Sharks are also used in cosmetics as leather and some other things. And they are invariably caught in drift nets which are intended for other specie such as tuna but grab anything of similar size. A large number go to this cause.

      Agree though this is unnecessary and as shown here a absurd use.

  6. Oh well, maybe they’ll find another critically endangered species to cruelly exploit to try to find a magical cure. I mean who wants to go through the trouble of eating a healthy diet when we could keep eating all the things linked to cancer and just off some rainforest or ocean creature to keep ourselves protected. Humans are a delight.

  7. Hello Dr. Greger and team

    We’re loving the regular videos coming out, keep it up. We really appreciate the service all of you guys are doing. We don’t thank the NF team enough. These videos have helped me personally manage my ulcerative colitis. Is there any chance you guys could cover Scleroderma in the future? It would be much appreciated If you guys could do a video in the future.

    Thank You guys again for your hard work :)

  8. Dr Gregor thank you so much for your research, you are great.

    I see where you are going to study Laetrile where some individuals are using it as a cancer alternative. It would be so wonderful if you could address all the cancer alternatives that are out there such as Essiac tea, Gerson, hyperbaric treatments, etc. etc. so many of them, but I would love to hear your take on this. Also, would you do chemo or radiation if you got cancer? What would you do?

    I am vegan for 26 years, 65 years of age, take no medication, take B12 as my only supplement and follow Dr John Mcdougall’s lifestyle, and yours and a few others. You guys are more than wonderful, thank you again. I heard you speak in 2016 on a vegan cruise. Dr Colin Campbell and Chef AJ were also there, it was fantastic. My husband and I were at the ADA in Seattle in 1992 and heard Dr McDougall speak and that is when we made the change. I have a 45 yr old stepdaughter that is battling cancer right now and she is doing chemo. I do not believe I personally would do it, what’s your take?

  9. Thank you Dr. Gerger for publishing this video on SCAM on shark’s cartilage for treatment of cancer. What I detested most is people exploiting wildlife, leading to their extinction to fattened up their own pocketbook!!!!. To me these people are CRIMINALS, crime perpetrated against wildlife, in this case, Sharks, and humans. The shark’s cartilage is the same type of “Snake Oil” Scam that is going on with Rhino horn and tiger bones. All those animal’s population are decimated from human greed.
