Analysis

The capsule supplies 100 mg trans-resveratrol with 50 mg red-wine grape concentrate and 50 mg grape extract. Species and polyphenol context are clear enough to show a focused three-part formula.

The knotweed source is identified, but purity and emodin-removal details are not supplied. A standard capsule offers no stated absorption advantage.

The large bottle supports long-term use, although the total package price is high. Its practical value is best for users who want grape polyphenols alongside a moderate resveratrol amount.

Who is it for
  • Adults seeking resveratrol with grape polyphenols
  • Long-term supplement users
  • People wanting transparent active amounts
Best for
  • Daily polyphenol support
  • Skin-oriented wellness routines
  • Larger-bottle convenience

Pros

  • Provides trans-resveratrol
  • Names knotweed and grape sources
  • Lists every active amount
  • Large number of servings

Cons

  • No enhanced delivery
  • Emodin removal is not verified
  • Purity is unstated
  • High package cost

Warnings

  • Knotweed-derived material may cause loose stools if emodin remains
  • Resveratrol and grape extracts may increase bleeding tendency with blood-thinning medicines

Nutrient quality

77 High impact

The trans isomer is clear, but standard capsule delivery and missing purity data limit form quality. Resveratrol reaches a supportive amount, while the two grape ingredients add moderate polyphenol breadth.

.

Ingredient transparency

84 Highest impact

Every listed active ingredient has a specific amount. Usage and inactive-ingredient details remain incomplete.

.

Customer satisfaction

57 Moderate impact

The average rating is exceptionally strong. The small feedback pool makes the average difficult to rely on confidently.

.

Value for money

49 Lower impact

The high price is not matched by premium delivery or exceptional dosing. Serving cost is high for a supportive trans-resveratrol amount.

Resveratrol · 100 mg

Trans-resveratrol provides a clearly identified mitochondrial and insulin-signaling active. Grape polyphenols add antioxidant context but do not create direct thermogenic support.

The active is supplied at a supportive amount, while standard capsule delivery and missing purity details limit confidence. The focused polyphenol design has moderate depth but no thyroid, stimulant, carnitine, or mineral pathway coverage.

Resveratrol · 100 mg

Trans-resveratrol and grape polyphenols provide focused antioxidant support relevant to photoaging. The formula is strongest for oxidative defense rather than hydration or structural repair.

The trans-resveratrol amount is useful, but purity and absorption support are not well documented. A lean ingredient list avoids padding while leaving other major skin pathways uncovered.
