ZMA Anabolic Bodybuilding Supplement

We predict every magazine to go crazy soon...
Seriously, you may not know it but it has already begun. Every bodybuilding magazine will soon have a large article about this amazing supplement! Every supplement company will make one. Twinlab, EAS, and Cytodyne already are selling them like crazy. ZMA products are the next big thing and they are here to stay!

What is ZMA? It is a scientifically designed anabolic mineral support formula. It contains Zinc Monomethionine Aspartate plus Magnesium Aspartate and vitamin B-6, and is an all-natural product that has been clinically proven to significantly increase anabolic hormone levels and muscle strength in trained athletes.

ZMA Studies

Check out the following study!

Hormones and Strength in Athletes

L. R. Brilla, Western Washington University, Bellingham, WA 98225, and V. Conte, BALCO Laboratories, Burlingame, CA 94010.

A double-blind, randomized study was conducted to determine the effect of a novel zinc and magnesium formulation (ZMA) on anabolic hormone levels and strength in athletes. Members of the University football team (n=27) had blood collected at the beginning and end of an 8 week period of intensive training. Subjects were supplemented with ZMA (n=12) or placebo (n=15) for the 8 weeks. The ZMA group took 3 capsules nightly that contained a total of 30 mg of ZN as monomethionine/aspartate, 450 mg of Mg as aspartate and 10.5 mg of vitamin B-6. The plasma Zn and Mg levels increased in the ZMA group by 29.1% (.804 to 1.038 mcg/ml) and 6.2% (19.43 to 20.63 mcg/ml), respectively, while levels decreased in the placebo group by 4.4% (.836 to .799 mcg/ml) and 9.2% (19.68 to 18.04 mcg/ml), respectively. The total and free testosterone levels in serum increased in the ZMA group by 32.4% (567.9 to 752.7 ng/dl) and 33.5% (132.1 to 176.3 pg/mL), respectively, in contrast to the placebo group which decreased by 10.5% (588.8 to 526.8 ng/dL) and 10.2% (141.0 to 126.6 pg/mL), respectively. The serum, IGF-1 levels increased in the ZMA group by 3.6% (424.2 to 439.3 ng/mL) and decreased in the placebo group by 21.5% (437.3 to 343.3 g/mL). All comparisons were statistically significant (P 0.001). Pre and post isokenetic strength determinations in newton meters were made using a Biodex dynamometer. Subjects (ZMA n=10; placebo n=11) were measured for maximum quadricep strength on the right leg at 180 degrees per sec (strength) and 300 degrees per second (functional power). The ZMA strength group change at 180 degrees per second was 11.6% (189.9 to 211.8) compared to the placebo group change of +44.6% (204.2 to 209.1) and the ZMA group change at 300 degrees per sec. was +18.2% (316.5 to 373.7), in contrast to the +9.4% (369.5 to 404.3) for the placebo group (P 0.05). These findings suggest that nightly supplementation with ZMA significantly increases Zn and Mg levels, anabolic hormone levels as well as strength and power in athletes.

Sports Medicine, Training and Rehabilitation Journal, November 1998 (in press)


This clinical study was presented to members of the American College of Sports Medicine conclusively proving the active component of ZMA increased anabolic hormones and strength by a staggering 250%!

In this study, a group of college football players who supplemented with ZMA and magnesium aspartate for eight weeks increased their free testosterone levels by over 43% more than test subjects who took a placebo. It's little wonder this same group of football players also increased their muscle strength 250% more than the placebo who didn't supplement with ZMA and magnesium aspartate. (Editor's note: I don't know about you, but that last sentence sends chills up my spine! Wow!) And in yet another study, ZMA was shown to "open up" anabolic receptor sites in the body!

ZMA Benefits

There are dozens of studies like this that have all shown the same thing. You simply take ZMA once per day 30 to 60 minutes before bed. (It also helps improve your sleep.) People across the country are using it and gaining more strength and size. Bodybuilders stuck on a plateau start ZMA supplementation and then set new personal strength records. Remember, this product is all natural!

ZMA Side Effects

Most people won't get any side effects from taking ZMA in the recomended amount. But taking too much could lead to ZMA side effects. Too much zinc could cause: copper deficiency, nausea, vomiting, dehydration and stomach problems. Too much magnesium could cause: diarrhea and Gastrointestinal distress. Too much vitamin B6 could cause: numbness of hands or feet, muscle spasms, sleeplessness and agitation.
