Checked against public sources between July 21 and July 24, 2026 · LookCloser does not sell or recommend supplements.
Does the marketing hold up?
The label’s 1,500 mg reads 3× larger than the berberine on the panel. Per-serving maths, not per capsule. 1,500 mg is what you get from 3 capsules. One serving on the panel has 500 mg. You are getting 500 mg of berberine per serving.
“Couldn’t verify” means we looked and found no public proof — not a mark against the product. Most supplement claims cannot be independently verified by anyone, so grey is the normal state of this industry.
