Other Ingredients (4)

Rice FlourFiller

Rice-based ingredients carry risk of inorganic arsenic contamination (FDA and Consumer Reports). Rice accumulates arsenic from soil at higher rates than other grains. Used as a cheap filler — adds nothing beneficial.

Silicon DioxideAnti-caking

Fine silica powder used to prevent clumping

GelatinCapsule

Protein derived from collagen, used in traditional capsule shells

How to Take It

Best taken in the evening

Magnesium glycinate is the gentlest form on the gut and the one most people take at night. Absorption doesn't change with the clock — consistency does.

With or without food
Space it a couple of hours from Iron and Calcium

On the label
