Yamamoto® Nutrition ZmaPRO is a dietary supplement containing zinc, magnesium and vitamin B6 for men, including sportsmen, that is very popular among athletes and bodybuilders. Its popularity is due to the benefits associated with the intake of zinc, magnesium and vitamin B6: zinc helps promote normal fertility and reproduction and maintain normal levels of testosterone in the blood, magnesium aids muscle function and helps reduce tiredness and fatigue, and vitamin B6 facilitates energy metabolism, nervous system function and red blood cell formation.

The advanced formula of Zma PRO combines zinc, magnesium and vitamin B6, three trace elements that play a crucial biological role. Studies supporting the ZMA combination show that it promotes anabolic and ergogenic activity mediated by stimulating the production and secretion of testosterone and the growth factor IGF-1. This product belongs to the group of dietary supplements known as Testo Boosters. It is often used in sports, and its benefits are not only limited to those who work out. It is well known that strenuous exercise is accompanied by increased vitamin and mineral requirements, that are not always satisfied by adequate nutrition. When it is not possible to follow a completely correct diet, food supplements are a valuable aid for both sporty and sedentary individuals alike.

Zma PRO intake brings several benefits:

  • Promotes muscular function - Zma PRO can be useful for those who do strenuous exercise. Athletes can see an improvement in strength and stamina;

  • Supports night-time recovery - The combination of zinc, magnesium and vitamin B6 facilitates muscle relaxation and the production of anabolic hormones: during sleep, the body regenerates and repairs muscle tissue damaged during physical activity;

  • Improved strength and stamina - Magnesium is involved in muscle contraction and energy production and vitamin B6 is involved in amino acid metabolism;

  • Promotes the production of anabolic hormones such as testosterone - Zinc is an essential mineral for testosterone production and magnesium is involved in its activation. A study conducted on endurance athletes showed a 30% increase in blood testosterone levels in athletes who took ZMA compared to the control group (which took a placebo).

  • Promotes immune system function - Zinc is essential for immune system function; it is involved in the production of various immune cells, including T cells and natural killer cells, and is necessary to protect against infection.

  • Involved in mood and sleep regulation - vitamin B6 can contribute to sleep quality and reduce symptoms of insomnia.

Our Advice

Zma PRO can be taken at different times, depending on the objective of intake; there is no ideal time. In general, it can be beneficial to take Zma PRO before bedtime, because the presence of magnesium reduces stress and improves sleep quality, on an empty stomach and away from calcium-rich meals (because calcium can interfere with zinc absorption).

Frequently asked questions

Can I take Zma PRO even if I am not an athlete?

By all means! ZMA Pro is also suitable for people who are not athletes and do not do strenuous exercise on a daily basis. The combination of zinc, magnesium and vitamin B6 is essential for the proper functioning of the body, regardless of the level of physical activity practised.

More specifically, ZMA Pro can be especially beneficial for those on restrictive diets or who have zinc or magnesium deficiencies. The Vitamin B6 present in ZMA Pro also supports the immune system and helps regulate mood and sleep.

How does Zma PRO affect hormone regulation?

ZMA, meaning Zinc-Magnesium Aspartate, is a combination of zinc, magnesium and vitamin B6. Its action on hormone production is mainly associated with its zinc and magnesium content.

Zinc is an essential mineral that plays an important role in the production of anabolic hormones like testosterone. Testosterone is a steroid hormone that promotes protein synthesis and muscle growth, and its level in the blood can be affected by the presence of zinc. Zinc is necessary for testosterone production because it is involved in the synthesis and secretion of the hormone.

Magnesium, on the other hand, is involved in testosterone activation. It is an important mineral for muscle contraction and energy production, but also for regulating the metabolism of steroid hormones like testosterone. Magnesium is required to convert testosterone into an active form known as dihydrotestosterone (DHT), which has an anabolic and androgenic effect on muscle cells.
