    Some time later...

    This is basically what's said on several websites... can't find any medical references on a basic search, but I'll keep digging (so far it's leaning towards, yes, it does work)

    here's the search: http://www.google.com/search?hl=en&q=zinc+and+magnesium+boost+testosterone&btnG=Google+Search

    Yes, a mixture of Zinc Monomethionine Aspartate, Magnesium Aspartate and vitamin B-6 often referred to as ZMA has been reported to boost testosterone. A study in the ACSM journal, Medicine and Science in Sports and Exercise, Vol. 31, No. 5, May 1999, showed that ZMA does in fact boost testosterone levels significantly and improve anabolic gains in athletes undergoing physical training. In the same placebo controlled study it was also been shown to increase Insulin Like Growth Factor-1 (IGF-1) which is a naturally occuring anabolic (muscle building)hormone. Other studies have tried to debunk this, however, there is a good body of both scientific and anecdotal evidence supporting the use of ZMA to increase testosterone in athletes that are training. This is especially relevant as vigorous training usually results in short term drops in testosterone and IGF-1. Over the long term of many months to years the baseline testosterone is increased by exercise. This study looked at the effects over an eight week period so this showed that it was the result of the ZMA and not the long term increase in baseline testosterone.

    However, do not think that ZMA is some wonder aphrodisiac, it's not an instant testosterone booster that will turn you into a sex machine, if it was the government would have declared it a steroid and made its use punishable by imprisonment by now. For this to work effectively you must be doing vigorous training, eating healthy, and have normal range healthy biochemistry. This will not boost testosterone in couch potatoes.

    Magnesium is easily depleted especially in vigorous training. A good percentage of adults do not get adequate Magnesium in their diets. This has been linked to everything from poor digestion to depression. So regardless of the naysayers out there this is a good , cheap supplement that offers numerous scientifically proven health benefits...a rare supplement indeed.

    I have seen this point made over and over again in many reputable sources.

    Just a word of caution if buying a magnesium supplement: When the bottle says, eg, 500 mg, it doesn't mean there is that much magnesium in the capsule. Magnesium always needs to be bound to another element (aspartate, citrate, etc) to be properly absorbed in the body. Most 500mg doses will have only about 80 or 100 mg. You have to check the bottle for "elemental magnesium" or else check out their website.

    Sources I checked say that for the normal healthy individual, 400 or 500 mg daily of elemental magnesium is safe and effective, but this includes food sources.

    This is from ConsumerLab.com:
    [b]What to Consider When Using:[/b]
    One's daily requirement for magnesium can be obtained through food sources without much difficulty and it is thought that the great majority of individuals in developed countries have an adequate intake. Especially rich sources of magnesium include whole grains, nuts, beans, avocado, shellfish, green leafy vegetables, coffee, tea and chocolate. A cup of whole grain flour has nearly 200 mg of magnesium. A cupful of spinach or most beans, nuts, seeds or trail mix offers anywhere from 50 mg to 150 mg of magnesium. A cup of milk, orange juice, or grapefruit juice provides about 80 mg.

    The recommended daily allowance (RDA) of magnesium is 80 mg for children 1 to 3, 130 mg for those 4 to 8, and 240 mg for those 9 to 13. For males 14 to 18 it is 410 mg, for those 19 to 30 it falls to 400 mg, and for those 31 years and older it is 420 mg.

    What happens if I already have an "over active" libido and decide to take ZMA? Will there be any change to my libido?
