PrizMAG Magnesium Bisglycinate Capsules contains magnesium bound to the amino acid Glycine. The addition of glycine is hugely beneficial when this form of magnesium is used to aid restful sleep, since both magnesium and glycine support quality sleep. Magnesium Bisglycinate is easier absorbed by the body and can be more beneficial compared to Magnesium oxide or magnesium citrate.PrizMAG pure magnesium bisglycinate is free from fillers, stearates and magnesium oxide, so you can be sure you are getting nothing but a high-quality supplement. This product binds to a glycine, which is an amino acid that is small enough to pass through your cell walls so that your body can absorb and utilize the magnesium, rather than pass right through your gastrointestinal tract like many other forms of magnesium.Great for those who prefer capsules over powder, and it doesn’t cause bowel intolerance. Magnesium helps to calm the central nervous system.
