ZMA

ZMA capsules combine zinc and magnesium, often with vitamin B6, and come in bottles of 90 to 180 capsules, some of them vegetarian capsules. The nutrition table lists each nutrient per daily serving and as a percentage of the nutrient reference value (NRV): 10 mg for zinc, 375 mg for magnesium and 1.4 mg for vitamin B6. The daily serving can be several capsules, so compare totals per serving rather than per capsule. The ingredient list names the compounds used for the minerals. Single-herb products such as tribulus have their own category.

Frequently asked questions

How does ZMA differ from separate zinc and magnesium products?

One ZMA serving combines zinc, magnesium and often vitamin B6, so its label has three lines to check instead of one. To compare it with single-nutrient products, put each amount in the same unit (mg or µg), compare per daily serving, and compare the percentage of the NRV for each nutrient.

How do I read the percentages on a ZMA label?

Each percentage compares the amount in the daily serving with the NRV: 10 mg for zinc, 375 mg for magnesium and 1.4 mg for vitamin B6. So 375 mg of magnesium is 100 % and 750 mg is 200 %. The percentage covers the whole serving, which may be several capsules, not one capsule.

What is the difference between the mineral and the compound on the label?

The amount of a mineral is normally stated for the mineral itself, with the compound it comes in named in brackets, for example magnesium (as magnesium aspartate). Two products can state the same milligrams of zinc from different compounds, and the ingredient list shows which. The weight of the compound is larger than the weight of the mineral it supplies.
