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 those 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.
Why Take ZMA?
ZMA in combination with weight training has shown to increase muscle size, endurance, and natural production of testosterone. ZMA has been shown to help individuals fall asleep faster, and stay asleep longer. ZMA may help increase weight loss but it’s not clear if this is true.
For athletes, supplementing with ZMA did show increases in performance. Some performance increases are most likely due to deficiencies in Zinc, Magnesium, and vitamin B6 from training, sweating, or lifestyle or nutrition deficits that could come from dietary preferences or inferior food quality.

When should you take ZMA?
The Magnesium in ZMA helps regulate sleep and can make you drowsy. Spend the day building up your sleep pressure through Body, Mind, and Spirit activity, and use ZMA an hour before bed to increase sleep pressure even more.
ZMA is a great alternative to Melatonin, the light regulating hormone which, if added to the body via supplement can turn-off the bodies natural Melatonin production making sleep difficult when no longer using Melatonin.[1] Melatonin is NOT sold over the counter in Australia, and many countries in Europe, including the UK.
Some patients in studies on ZMA reported feeling nauseous if they took ZMA with food, so it’s best to take at night once you have stopped eating for the day.
