Other Ingredients (2)

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

Best taken in the evening

Take 30–60 minutes before bed. It's a circadian signal, not a daytime supplement.

With or without food

On the label

As a dietary supplement, take 1 capsule daily at or near bedtime 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.
