Magnesium without the trade-off. Thorne binds it to glycine, two molecules of it, and the bisglycinate form that results is well absorbed and far gentler on digestion than the magnesium salts that send people running.

Magnesium is a cofactor in hundreds of the body's enzyme reactions, and it has a hand in muscle relaxation, normal nerve signalling, bone structure and normal energy production.

The powder mixes clear into water or juice and is sweetened only with monk fruit concentrate, with citric acid for a little lift. No sugar and no sweetener aftertaste, which is the difference between a supplement you keep taking and one that sits in the cupboard.
