Other Ingredients (3)

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

HypromelloseCapsule

Plant-derived capsule material from cellulose

How to Take It

Best taken in the morning

A caffeine source — treat it like coffee and keep it well clear of bedtime.

With or without food

On the label

As a dietary supplement take 1-2 capsules daily with 8-12 oz of water or as directed by your healthcare professional. The recommended dose of this product contains as much caffeine as about 2 cups of coffee. Do not consume more that 400 mg caffeine from any source in a 24 hour period. Too much caffeine may cause nervousness, irritability, sleeplessness, and occasional rapid heart rates. In case of accidental overdose, seek professional assistance or contact a poison control center immediately.

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