Other Ingredients (5)

MaltodextrinBinder

Spikes blood sugar faster than table sugar (glycemic index 85–105). Research links it to gut bacteria changes that may promote intestinal inflammation (Nickerson et al. 2015). Used as a cheap filler — adds nothing beneficial.

Silicon DioxideAnti-caking

Fine silica powder used to prevent clumping

Magnesium StearateLubricant

A salt of stearic acid used as a lubricant in tablet and capsule production

Dicalcium PhosphateBinder

Calcium and phosphorus compound used as binder

GelatinCapsule

Protein derived from collagen, used in traditional capsule shells

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
Label directs 2 servings — keep one for the morning

On the label

For adults, take two (2) capsules twice daily, preferably with meals. Capsules may be opened and prepared as a tea.

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