Analysis

The two-capsule serving supplies 250 mg trans-resveratrol from Japanese knotweed. That clear active amount gives the formula a solid resveratrol foundation.

Olive leaf extract at 150 mg is identified by oleuropein, while a 100 mg grape blend hides its components. A small MCT powder addition may support formulation but is not a major dose.

The blend offers broader vascular and antioxidant coverage than resveratrol alone. Thirty servings are practical enough, though medication interactions and knotweed processing need attention.

Who is it for
  • Adults seeking trans-resveratrol with olive leaf
  • Users wanting broad vascular polyphenols
  • People comfortable with a two-capsule serving
Best for
  • Cardiovascular-oriented polyphenol routines
  • Anti-aging support
  • Users wanting olive leaf alongside resveratrol

Pros

  • Provides 250 mg trans-resveratrol
  • Identifies Japanese knotweed source
  • Provides 150 mg olive leaf
  • Names oleuropein marker

Cons

  • Grape blend is opaque
  • Resveratrol purity is not stated
  • Emodin removal is unverified
  • Requires two capsules

Warnings

  • Resveratrol may add to anticoagulant or antiplatelet effects
  • Olive leaf may add to blood-pressure-lowering medicines
  • Japanese knotweed may cause laxative effects when emodin removal is unverified

Nutrient quality

83 Highest impact

Meaningful trans-resveratrol and complementary olive-leaf compounds provide good polyphenol depth. Standard delivery and an opaque grape blend leave some quality uncertainty.

Ingredient transparency

67 High impact

Core active quantities and forms are clearly disclosed. A smaller hidden blend, missing directions, and absent excipients leave moderate gaps.

Customer satisfaction

72 High impact

The supplied average rating is very strong and the rating volume is substantial. No specific experience details were provided to judge repeated complaints or purpose alignment.

Value for money

81 Highest impact

Formula quality and practical serving value support a favorable cost assessment. It compares well within the category despite remaining formulation limits.

Trans-resveratrol at 250 mg combines with olive leaf and grape polyphenols to support vascular aging, oxidative defense, and cellular stress signaling. The main active and olive leaf amounts are clear, while the grape blend remains opaque.

The formula provides broader polyphenol coverage than resveratrol alone but does not address mitochondrial energy or structural aging. Resveratrol may increase bleeding with anticoagulant or antiplatelet medicines, and Japanese knotweed extracts without an emodin-removal claim may cause loose stools.

Resveratrol · 250 mg

Trans-resveratrol supplies the clearest metabolic support through mitochondrial and insulin-sensitivity signaling. Olive leaf and grape compounds broaden antioxidant coverage but have less direct evidence for raising metabolism.

Missing purity, active-yield, delivery, and emodin-removal details limit confidence in the knotweed extract. Residual emodin from Japanese knotweed may cause loose stools if the extract is not properly purified.

B- Goal FitB+ Strength of SupportC CoverageB Formula Quality

Trans-resveratrol, olive-leaf oleuropein, and grape compounds provide a focused antioxidant and endothelial-support combination. The formula may help vascular signaling but lacks stronger lipid, rhythm, homocysteine, and cardiac-energy coverage.

Resveratrol and olive-leaf amounts and markers are clearly disclosed, while the grape blend is less transparent. Olive leaf and resveratrol may lower blood pressure, so combining them with antihypertensive medicines may increase dizziness or fainting risk.

Resveratrol · 250 mg

Trans-resveratrol, olive leaf, and grape compounds provide a broad antioxidant strategy that may support skin resilience to environmental stress. Evidence is plausible for photoprotection, but direct improvements in wrinkles or hydration are not strongly established for this combination.

The trans-resveratrol amount is meaningful and its botanical source is named. Purity, emodin removal, and the contents of the grape blend are not fully disclosed, so mild laxative effects from Japanese knotweed remain a practical possibility.

Trans-resveratrol and olive leaf provide relevant polyphenol support for inflammatory and oxidative-stress signaling. The resveratrol amount is meaningful, but the evidence is less direct and consistent than for established options such as fish oil or curcumin.

Individual amounts are listed, yet resveratrol purity, olive-leaf standardization, and the grape blend composition remain unclear. Japanese knotweed without an emodin-removal claim may cause mild laxative effects in sensitive users.

The label clearly identifies a therapeutic amount of trans-resveratrol from Japanese knotweed. Standard capsule delivery and missing purity percentage limit bioavailability and refinement assurance. Cost efficiency is good, but no emodin-removal claim means mild laxative effects remain a source-specific concern.
