Buying Guide: What to Look For in a ZMA Supplement
Zinc and Magnesium Forms
The type of minerals matters for absorption. Optimum Nutrition uses zinc and magnesium aspartate, a chelated form believed to be well absorbed. NOW Sports uses a blend of zinc monomethionine and magnesium glycinate, which are also highly bioavailable. Both are excellent choices, but if you prefer aspartate, go with Optimum Nutrition.
Serving Size and Convenience
All three products recommend three capsules per serving. Optimum Nutrition offers a 180-count bottle (60 servings) and a 90-count bottle (30 servings). NOW Sports also offers 180 veg caps. Think about how long you want your supply to last. If you travel frequently, the smaller bottle might be more convenient.
