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.

Brand Reputation and Quality

Optimum Nutrition is a trusted name in sports nutrition, known for rigorous quality control. NOW Sports is equally respected, with a long history of producing clean supplements. Both brands are frequently recommended by fitness experts. For more on reliable supplement brands, read our youtheory collagen review or codeage multi collagen review.
