The formula combines 100 mg trans-resveratrol from two named sources with 120 mg quercetin dihydrate. That pairing offers balanced polyphenol coverage in a simple capsule.
Grape and Japanese knotweed identity are clear, but source-specific yields and purity are not. No delivery technology or emodin-removal verification is stated.
Low routine cost and a large serving count make the product practical for daily use. Its quality case rests on transparent core amounts rather than specialized absorption.
Trans-resveratrol sources and quercetin dihydrate are useful forms, but the standard capsule lacks enhanced delivery. Resveratrol appears supportive and quercetin is meaningful, though duplicate source entries make the total dose unclear.
.Specific amounts are shown, but duplicate resveratrol source entries make the total active dose ambiguous. Usage and inactive-ingredient details remain incomplete.
.The average rating is exceptionally strong. The substantial feedback pool makes the average reasonably dependable.
.The focused polyphenol combination provides strong quality for its modest price. Economical serving cost supports excellent practical value.

Trans-resveratrol and quercetin provide a focused polyphenol combination that may support oxidative defense against environmental stress. The supplied ingredient data indicates supportive resveratrol and quercetin amounts, though extract purity is not standardized.
Coverage remains limited to antioxidant protection, with no collagen building blocks or hydration-barrier ingredients. Japanese knotweed is used without an emodin-free statement, so sensitive users may experience a laxative effect if residual emodin is present.
Resveratrol with quercetin offers modest support for cellular and glycemic signaling. Human evidence for a noticeable metabolism boost is inconsistent.
The formula fits healthy-aging support better than direct thermogenesis. The duplicate resveratrol entries should be clarified before assuming their amounts are additive.
| Ingredient | Amount per serving |
|---|---|
Trans-Resveratrol (Grape (fruit) extract, Japanese Knotweed (root) extract) | 100 mg |
Quercetin (Quercetin Dihydrate) | 120 mg |
Trans-resveratrol is clearly identified from grape and Japanese knotweed at a combined supportive dose. The standard capsule lacks advanced delivery and the label does not provide purity percentages or separate extract yields. The knotweed source has no emodin-free statement, so residual emodin could cause mild laxative effects in sensitive users.
