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.

Magnesium StearateLubricant

A salt of stearic acid used as a lubricant in tablet and capsule production

Citric AcidAcidulant

Natural acid derived from citrus fruits

Microcrystalline CelluloseBinder

Plant-derived cellulose used as a binder and filler in supplements

How to Take It

Best taken in the morning

Bisglycinate is the gentle form — most people tolerate it on an empty stomach, which is exactly where it absorbs best. Vitamin C may help absorption.

On an empty stomach
Keep it away from coffee, tea and dairy
Space it a couple of hours from Calcium, Zinc, Magnesium, Manganese and Green Tea Leaf Extract

On the label

As a dietary supplement, take 1 capsule daily with 8-12 oz of water or as directed by your healthcare professional.

General guidance based on the ingredients, not a substitute for the label or your doctor.
