Vitamin C provides the largest disclosed active amount, while trans-resveratrol totals only 40 mg across grape and knotweed sources. The product is therefore better viewed as a grape-seed antioxidant formula than a focused resveratrol supplement.
A 100 mg proprietary blend conceals its individual components and doses. Knotweed purity and emodin removal are not verified.
Routine cost is moderate, but resveratrol-specific value is weak. Users seeking grape-seed compounds also lack a clear standardized proanthocyanidin amount in the supplied data.
Calcium ascorbate and named trans-resveratrol are useful forms, but the standard capsule lacks enhanced delivery. The combined trans-resveratrol contribution is small, and the proprietary blend cannot be evaluated for active depth.
.Vitamin C and resveratrol amounts are shown, while the proprietary blend components lack individual doses. Usage and inactive-ingredient details remain incomplete.
.The average rating is consistently strong. The substantial feedback pool makes the average reasonably dependable.
.The price is not well supported by the small resveratrol contribution and hidden blend. Serving value is weak for resveratrol-focused use.
.| Ingredient | Amount per serving |
|---|---|
Vitamin C (Calcium Ascorbate) | 250 mg |
Calcium (Calcium Ascorbate) | 25 mg |
Proprietary Blend | 100 mg |
Trans-Resveratrol (Grape (fruit) extract, Japanese Knotweed extract) | 20 mg |
The formula identifies small amounts of trans-resveratrol from grape and Japanese knotweed, but it remains primarily a grape-seed blend. Standard capsule delivery and missing purity details limit absorption and source confidence. The knotweed component lacks an emodin-free statement, so residual emodin could cause mild laxative effects in sensitive users.
