Magnesium oxide is the cheapest form of magnesium on the market. It is also the least bioavailable, with absorption rates as low as 4%.
Magnesium glycinate, on the other hand, is a chelated form bound to the amino acid glycine. This chelation protects the magnesium through the digestive tract and delivers it directly into your bloodstream.
The Absorption Difference
Clinical studies show magnesium glycinate has roughly 80% bioavailability compared to magnesium oxide at 4-10%. That means a 350mg dose of glycinate delivers about 280mg of usable magnesium, while the same dose of oxide delivers only 14-35mg.
ZENYVA uses magnesium glycinate precisely because your body deserves the form that actually works.
