Other Ingredients (5)

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

Silicon DioxideAnti-caking

Fine silica powder used to prevent clumping

GelatinCapsule

Protein derived from collagen, used in traditional capsule shells

Stearic AcidLubricant

Saturated fatty acid used as tablet lubricant

How to Take It

Take it anytime

Take with plenty of water. Fiber binds other things in the gut, so give it a 1–2 hour gap either side.

With food
Keep it away from medication and mineral supplements

On the label

As a dietary supplement, take 3 capsules 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.
