The supplement ZMA It combines three essential micronutrients: zinc, magnesium and vitamin D. It has become popular because it is associated with improvements in testosterone levels, sleep quality, and muscle recovery. But… what is true, and what does science say?

What is ZMA?

ZMA is not a "magic" substance, but rather the combination of three nutrients that the body needs daily:

• ZincIt participates in more than 300 enzymatic reactions, including those related to the immune system and hormone production.
• Magnesium: key mineral in muscle function, relaxation and energy synthesis (ATP).
• Vitamin D: essential for bone health, immune function and an important regulator of hormone production.

Does testosterone really increase?

Scientific studies show that:

• In people with zinc or vitamin D deficiency, Supplementing with ZMA may help normalize testosterone levels.
• In people healthy and with adequate levels, the increases are usually not significant.
  In other words, ZMA doesn't turn anyone into a "superman," but it does prevent drops in testosterone caused by deficiencies.
