What is ZMA?
ZMA is a supplement containing a blend of zinc, magnesium, and vitamin b6: the A in ZMA.
Every ZMA supplement has a different blend of the three key ingredients. The variation of the blend depends on the quality of the supplement and the form it’s consumed in.
Most ZMA supplements come in capsules. There are some liquid & powder forms of ZMA but they’re not as common as the traditional capsule forms, or as good.
Why Take ZMA?
ZMA in combination with weight training has shown to increase muscle size, endurance, and natural production of testosterone. ZMA may help increase in weight loss but it’s not clear if this is true.
The studies done on ZMA are mixed. Some studies showed no increase in performance when taking ZMA.
However, for athletes, supplementing with ZMA did show increases in performance but this is most likely due to deficiencies in Zinc, Magnesium, and vitamin B6 from training, sweating, and lifestyle or nutrition-deficits.
the majority of studies show ZMA doesn’t have a positive benefit, but more research is needed for a accurate conclusion.
- Effects of Zinc Magnesium Aspartate (ZMA) Supplementation on Training Adaptations and Markers of Anabolism and Catabolism
- Micronutrients (magnesium, zinc, and copper): are mineral supplements needed for athletes?
- Exercise, nutrition and immune function.
Studies aside for a moment, many people swear by ZMA as a sleep aid alternative to melatonin–the light-hormone supplement–shown to disrupt your natural production of melatonin. 
And, just because a study says something may not work, doesn’t mean you shouldn’t try it. Everyone is different and what doesn’t work for someone else may be the answer you’ve been looking for. Since sleep is when your body recovers, getting good sleep is crucial to your health and your performance as an athlete.
Try Everything. Keep what works and disregard the rest.
