Biotest ZMA 90 Capsules Enhance strength, endurance, recovery, & growth with the original ZMA formula from SNAC System. ZMA is an advanced zinc/magnesium formulation designed to replace deficiencies caused from exercise & stress.ZMA is a scientifically designed mineral-support formula that can dramatically increase natural levels of anabolic hormones & improve athletic performance. In fact, if taken as recommended, ZMA can increase free testosterone by 30% while boosting IGF-1 levels significantly. Zinc & magnesium deficiencies are common in the general population & even more prevalent in athletes. To illustrate the point, in 1998, the mineral status of over 250 NFL players was tested. Over 70% of the players were either depleted or deficient in both zinc & magnesium. It sounds almost unbelievable because of all the attention we give to good nutrition, but most athletes & active people are deficient in zinc & magnesium which results in decreased hormone levels & diminished strength & power. The Cause of Zinc & Magnesium Deficiencies Why are we so deficient in zinc & magnesium? Probably the biggest reason is that rigorous exercise & stress result in significant mineral losses. &, to make matters worse, most ordinary types of zinc & magnesium are poorly absorbed ? it's very difficult to recover proper amounts without specific supplementation. The Solution ZMA is designed to combat these deficiencies. University studies have found that the zinc & magnesium contained in ZMA are absorbed far better than other forms. An independent ZMA study was recently conducted on competitive NCAA football players at Western Washington University. The results show that, in eight weeks, the ZMA group increased free & total testosterone levels by 30%, while the placebo group showed a decrease of 10%. The ZMA group also had a slight increase in IGF-1 levels compared to a 20% decrease in the placebo group. In addition to increasing anabolic-hormone levels, the ZMA group gained 2.5 times more strength & functional power over the placebo group. What to Expect So, if you're an athlete, or you're under a lot of stress, you probably need extra zinc & magnesium to perform at your best. & if you incorporate ZMA into your supplement program, odds are you'll attain the same kinds of increases in testosterone & GH production that many athletes have already experienced.
