Vascular and metabolic longevity are addressed through a multi-pathway approach including Resveratrol, Green Tea Phytosome, and R-Lipoic Acid. These ingredients appear well-aligned with goals for maintaining cardiovascular flexibility and mitochondrial efficiency.

The use of advanced Greenselect Phytosome technology significantly improves the absorption of the green tea catechins. However, the 50mg dose of resveratrol is relatively low compared to standalone clinical products for sirtuin activation.

Thorne L-Arginine Plus includes 50mg of trans-resveratrol along with Green Tea Phytosome to support cardiovascular and circulatory health. It is a high-quality, pure formula, but the resveratrol dose is strictly supportive.
