what is the difference between magnesium glycinate and bisglycinate?
Let's clear up something important: Magnesium bisglycinate and magnesium glycinate are 2 names for the same thing. Magnesium bisglycinate is a magnesium atom attached to two glycine molecules. “Bis” means 2, referring to the 2 glycine molecules, so we prefer to use the name bisglycinate for clarity.
