Overview

This resveratrol supplement provides 125 mg of natural trans-resveratrol per capsule, which is within the clinically effective dosage range (150-500 mg/day) seen in studies for metabolic and vascular benefits. While the specific proprietary blend components are disclosed, the individual contribution of wine grape concentrate to the overall efficacy beyond the purified trans-resveratrol is not precisely quantified. The efficacy is supported by moderate to high-quality evidence, particularly for cardiovascular and metabolic improvements in at-risk populations.

The Good

Provides a clinically relevant dose of 125 mg natural trans-resveratrol per capsule, an active and well-researched form.

Resveratrol offers antioxidant and anti-inflammatory support, contributing to overall health and cellular protection.

May improve endothelial function and metabolic parameters such as waist circumference, HbA1c, and LDL cholesterol, particularly in at-risk individuals.

The Bad

The term "Proprietary Blend" partially obscures the exact proportions of wine grape concentrate and purified resveratrol within the 250mg blend, though the trans-resveratrol content is disclosed.

Resveratrol has limited oral bioavailability due to rapid metabolism, which may impact its systemic effectiveness.

Potential for drug interactions, especially with blood thinners and certain medications metabolized by the liver, necessitating professional medical consultation.
