    Since SHBG being high is considered “good” in this video, it is also good to note that with high levels of SHBG the levels of Free Testosterone go down. Why is this a good thing then to have some experience of Low T? Isn’t there health concerns with the Free Testosterone levels being too low?

    I am a Vegan and have been since 1999. In summer 2013 I decided to have grass fed dairy and by spring of 2014 I realized it didn’t work for me. I was concerned about getting older and keeping overall Testosterone levels healthy. I am 44. I saw your video on “Vegans have the highest Testosterone levels.” I went back to being vegan!

    Then July of 2014 I tried having eggs for a month and noticed bodyfat levels decreasing and muscle mass increasing as well as a more youthful sex drive. I chose to go back to being vegan ever since Aug of 2014.

    I feel like some things in these videos are being left out. You have a video on vegans having the highest T levels. However, SHBG, if I am correct, is directly proportionate to levels of bioavailable or FREE Testosterone? If a vegan would have the highest SGBG levels, than how could they have the highest bioavailable or FREE Testosterone? They might have the highest Total Testosterone, but if they have high SHBG levels then isn’t there “high levels of Testosterone” going to be “bound” to SHBG and NOT bioavailable as Free Testosterone? Isn’t this a little confusing then about vegans having the highest testosterone ?

    There might be health concerns with high levels of SHBG, but there are also health concerns with low levels of Free Testosterone isn’t there? If I am wrong in any of my information then please correct me. However, if I am correct, then please realize that it would be helpful to sometimes “tie” the information in these videos together even if it doesn’t 100% make your point you are trying to make.
