Berberine hydrochloride is supplied at 500 mg, while decaffeinated green-tea extract contributes catechin and EGCG markers. The combination is directly relevant to glucose and lipid metabolism rather than broad anti-aging support.
The supplied data also list 200 mg under a caffeine form despite describing the extract as decaffeinated. That internal inconsistency needs package-label verification because it changes both tolerability and safe timing.
One capsule is convenient and the active amounts are substantial, though gastrointestinal tolerance and medication interactions matter more than serving simplicity. The formula best suits informed users who specifically want berberine plus green-tea catechins.
Decaffeinated green tea markers and berberine hydrochloride are useful forms, but the caffeine entry conflicts with the decaffeinated claim. Meaningful actives support the concept, but conflicting stimulant data and berberine interaction potential are important trade-offs.
Repeated green tea marker amounts and a contradictory caffeine entry make the label internally unclear. No proprietary blend hides the listed active doses.
The supplied average is very strong, with limited response volume. Complaint patterns and purpose-related experiences are not supplied.
The asking price is difficult to justify for the disclosed formula. Serving value is weak relative to the green tea support provided.
Berberine and EGCG provide complementary metabolic, antioxidant, and inflammatory support. Both actives appear at meaningful amounts, creating more pathway breadth than a single-ingredient product.
The data call the green tea extract decaffeinated but also list 200 mg of caffeine, so stimulant exposure is unclear. That discrepancy matters for people with caffeine sensitivity, sleep problems, or stimulant-sensitive heart rhythm symptoms and should be resolved from the package label before use.
| Ingredient | Amount per serving |
|---|---|
Berberine HCl (Phellodendron amurense bark extract) | 500 mg |
decaffeinated Green Tea (Camellia sinensis) leaf extract (Catechins, Epigallocatechin Gallate, Caffeine) | 200 mg |
The label discloses a 200 mg EGCG amount from decaffeinated green tea extract, placing it in the effective range. No delivery technology is included to improve catechin absorption. The cost per active target amount is high, and berberine remains the formula's main focus.
