Kirkman Labs' Magnesium Bisglycinate Buffered Chelate is a mineral supplement designed to provide magnesium in a form that the manufacturer states is gentle on the digestive system and supports relaxation and restful sleep.

The capsules are buffered to resist pH changes in solution, further aiming to minimize digestive tract irritation.
