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.

GelatinCapsule

Protein derived from collagen, used in traditional capsule shells

How to Take It

Take it anytime

Take with food — on an empty stomach it commonly causes nausea.

With food
Space it a couple of hours from Iron and Calcium

On the label

As a dietary supplement, take one capsule per day with food and water. Taking zinc on an empty stomach may cause stomach upset in some people.

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