Which ZMA Supplements Work?
ZMA supplements are hard for companies to screw up. Surprisingly, some manage to do it. Essentially, you want a ZMA supplement that uses the formula: 30mg of zinc, 450mg of magnesium and 10.5mg of vitamin b6.
Whether you’re a competitive athlete, a bodybuilder, or just want to get in shape, ZMA supplements can help.
