Title: ZMA
Review: I'm not 100% percent sure if this product helps to boost testosterone production. There are some mixed reviews about that at this point. Most people are deficient in magnesium and zinc so it helps with that. The best part of this product for me, and the secondary purpose for buying it, is that it helps me sleep very deep, restful sleep so it's worth every penny to me.
