Product analysis
PolyResveratrol-SR combines resveratrol and plant extracts with limited support for visible skin benefits and uncertain effects on everyday energy expenditure. Its relatively high cost and undisclosed mixture details make it harder to justify for those goals.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality31
Some plant preparations are named, but their quality cannot be established from those names alone. Unidentified blend components and unnamed forms for resveratrol and pterostilbene add uncertainty.
Ingredient Transparency68
Ingredient totals are disclosed, but the three mixtures lack component breakdowns. That leaves the amounts of their individual substances unclear despite several named preparations.
Value For Money16
Curcumin and resveratrol are expensive at the serving cost. Green-tea value cannot be compared reliably because the amount of its relevant compounds is unknown.
Customer Satisfaction85
Buyers give high ratings across a substantial number of reviews. That supports positive customer sentiment without establishing the claimed metabolic or skin effects.
Product Focus40
The combination relates to skin and metabolism goals, but benefits remain uncertain for both. The undisclosed blend composition also prevents a complete picture of how many active substances it contains.
