I am not sure about it, what I know about dietary supplements is the fact that they are no longer required to be approved by the FDA
Yes, we now have the DSHEA they are responsible for determining safety for taking dietary suppliments, which was not in place back then
I am thinking about starting to bodybuild. Speaking of bodybuilding, did you know that the bodybuilding supplement industry grew a lot during the 1970s and 1980s? I didn't know that, I think it has got safer as the years have gone by. Have you tried herbal concoctions and tonics ? Those have been used to try increasing stamina and strength by athletes since long ago I have never heard of those. What kind of supplements would best increase mass gains? I am not sure, but in Ancient Greece bodybuilders were advised to eat lots of meat and drink lots of wine I think today there is a lot of man made chemicals in powder form. Have you ever heard of Eugen Sandow? He was an advocate for the use of dietary control in order to enhance muscle growth I have never heard of this person before. Did he advocated for dietary supplements as well?
Under DSHEA, responsibility for determining the safety of the dietary supplements changed from government to the manufacturer and supplements no longer required approval from the U.S. Food and Drug Administration (FDA) before distributing product.
