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.
Ascorbyl PalmitateAntioxidant
Fat-soluble form of vitamin C used as preservative
HypromelloseCapsule
Plant-derived capsule material from cellulose
How to Take It
Best taken in the morning
Contains caffeine — keep it to the morning. Take with food; high-dose EGCG on an empty stomach stresses the liver.
With food
Keep it away from iron-rich meals
Space it a couple of hours from Iron
On the label
1 to 2 capsules 2 to 3 times daily, or as directed by a healthcare practitioner. Between meals is best but not mandatory.
The label says to take it on an empty stomach. What's in this one sits better with food, and you give up little by taking it that way.
General guidance based on the ingredients, not a substitute for the label or your doctor.
