ZMA

This post was originally posted on the Weights.net listserve. Mel suggested

that I submit it here as well.

From Krieger:

>In a paper by Lori Brilla of Western Washington University, football

players who consumed ZMA experienced greater gains in strength, as well as

increases in serum T. I talked to Lori at ACSM and she told me how all the

supplement companies have been misuing her study to sell ZMA. These

football players were deficient in their dietary intake of zinc and

magnesium. There's no evidence that ZMA will boost T in someone who is not

deficient in zinc or magnesium. Assuming that you are consuming a

well-balanced diet, along with a multivitamin/mineral, I don't see how ZMA

will help you. >

In addition to echoing ' comments, I would add that the actual paper is at:

<http://www.css.edu/users/tboone2/asep/Brilla1ColV2.doc>

The paper indicates that other forms of zinc and magnesium are related to

testosterone and/or IGF-1 levels (see the introduction). While I have found

athletes to be low in zinc and/or magnesium, in most cases we were able to

correct this easily

just with making some more appropriate food choices.
