What is ZMA?
ZMA is a scientifically designed anabolic mineral 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.
An increase in exercise can lead to the loss of vitamins and minerals, making it particularly important for bodybuilding due to the blood sugar level rises and urination increases, increasing the loss of magnesium, zinc, B12, B6, folic acid, and many other nutrients.
Benefits of taking ZMA:
Obviously, the main benefit from increasing testosterone levels is increased strength and muscle mass. Users of ZMA have often reported the following effects:
- Increased muscle mass
- Increased strength
- More energy
- Increased libido
- Elevation of mood (testosterone has been used to treat depression)
- Deeper and longer sleep
Scientific evidence supporting ZMA:
There is a large amount of evidence supporting ZMA. Recent studies have shown that Zinc and Magnesium are often deficient in athletes and supplementing with ZMA can increase testosterone levels by up to 30%!
Lorrie Brilla, PhD, a sports performance researcher at Western Washington University, recently reported that ZMA significantly increase free testosterone levels and muscle strength in NCAA football players.
These ZMA study results were presented by Dr. Brilla on June 2, 1999, at the 46th Annual Meeting of the American College of Sports Medicine in Seattle, WA, and were published in the official ACSM journal, Medicine and Science in Sports and Exercise, Vol. 31, No. 5, May 1999.
Lorrie Brilla reported that:
"A group of competitive NCAA football players who took ZMA nightly during an eight-week spring training program had 2.5 times greater muscle strength gains than a placebo group. Pre and post leg strength measurements were made using a Biodex isokinetic dynamometer." The strength of the ZMA group increased by 11.6% compared to only a 4.6% increase in the placebo group.
"The muscle strength increases may have been mediated by the anabolic hormone increases in the ZMA group. The ZMA group had 30% increases in free and total testosterone levels compared to 10 percent decreases in the placebo group... The ZMA group also had a slight increase in insulin-like growth factor-1 (IGF-1) levels compared to a 20 percent decrease in the placebo group. This study shows that anabolic hormone and muscle strength increases can be induced in already strength-trained athletes by using a novel zinc-magnesium preparation."
ZMA supplements and dosages:
ZMA supplements come in pill or capsule form. It’s typically taken once to twice daily, prior to training and on a empty stomach before bed. Dosages may vary between products, always follow the instructions on the label.
Does ZMA have any side effects?
ZMA is made from all natural ingredients and has no known side effects. It is safe for both men and women.
