Magnesium Glycinate vs. Magnesium Bisglycinate: Know the Difference

Shumaila Saeed
By Shumaila Saeed || Updated on December 25, 2023
Magnesium Glycinate is a magnesium salt bonded with one glycine molecule, while Magnesium Bisglycinate contains two glycine molecules bonded to magnesium.
Magnesium Glycinate vs. Magnesium Bisglycinate

Key Differences

Magnesium Glycinate is a compound where magnesium is bonded to the amino acid glycine. This form is typically used for its calming effects on the brain and its efficiency in absorption. Magnesium Bisglycinate, on the other hand, refers to a similar compound where each magnesium ion is bonded to two glycine molecules. This difference in molecular structure can influence the way the body absorbs and utilizes the magnesium.

When discussing Magnesium Glycinate, its notable for its high bioavailability and less likelihood to cause laxative effects. This is due to the presence of a single glycine molecule, which facilitates easier digestion and absorption. In contrast, Magnesium Bisglycinate contains an additional glycine molecule, which may enhance the stability of the compound and potentially improve its digestive tolerance, though the difference is often subtle.

In terms of benefits, Magnesium Glycinate is widely recognized for supporting muscle health, improving sleep quality, and managing stress and anxiety. Its single glycine component also plays a role in neurotransmitter function. Magnesium Bisglycinate, with its double glycine content, is thought to offer similar benefits, but with possibly an added advantage in terms of gut health and gentleness on the digestive system.

The choice between Magnesium Glycinate and Magnesium Bisglycinate often comes down to individual tolerance and specific health needs. While both offer the essential benefits of magnesium, the presence of one versus two glycine molecules in Magnesium Bisglycinate can slightly alter its absorption rate and gastrointestinal impact compared to Magnesium Glycinate.
