Testosterone is an anabolizing hormone that the human body produces in varying amounts. The more we produce it, the higher our sporting achievements, as well as indicators of strength and endurance. It also helps the body recover from physical exertion. Testosterone is a muscle-building hormone! Accelerators offered to us are mainly of plant origin. For example, Tribulus (Tribulus – Creeping Anchors) or Lepidium meyenii.
A certain popularity began to use a mixture of ZMA. This is a mixture of 30 milligrams of zinc aspartate, 450 milligrams of magnesium aspartate and 10 milligrams of vitamin B6. The abbreviation ZMA is a registered trademark that many sellers use more or less legally.
The first study on ZMA was funded by the blend maker. It was about his results that a lot was said before launching the drug into a wide sale. L. Brilla (2000) studied the effect of ZMA on American football players during eight weeks of training. When they took ZMA, their zinc plasma level increased by 29%, and when they received placebo, they decreased by 4%. Magnesium levels increased by 6%, while those taken with placebo decreased by 9%. Thanks to ZMA, the level of testosterone increased by 33%, while taking placebo decreased by 10%. The level of IGF-1 (insulin-like growth factor) increased by 3%, but decreased by 21% with placebo. The jerk strength improved twice as fast with ZMA (+ 18%) than placebo (+ 9%).
The results are amazing, especially when it comes to increasing testosterone levels. However, C. Wilborn (2004) does not endorse them. In the course of his study, men who regularly pumped out their muscles took either ZMA or placebo for eight weeks. With the exception of a slight decrease in the level of various catabolism indicators, no positive effect of ZMA on the level of zinc, magnesium, testosterone, IGF, strength or muscle mass was recorded. This data seems to correspond more to reality. In addition, ZMA is an expensive form of zinc and magnesium. Such supplements can benefit athletes who lack one of two minerals, but, according to Wilborn, to a very small extent.
Thus, if you do not take into account intense training, you can not argue that there is a natural supplement that can dramatically increase the production of testosterone.
