You're getting 300mg of **maritime pine bark extract** in one daily capsule — above the 50–200mg range used across clinical trials. At this dose you're fully covered for what this ingredient is studied for: improving venous circulation and leg-vein function, supporting skin elasticity and UV resistance, and helping manage blood glucose.

The extract is standardized to at least 95% proanthocyanidins — the procyanidin compounds behind its antioxidant and anti-inflammatory activity — so what you're taking is a concentrated, consistent active fraction. One capsule a day keeps your dosing simple, with nothing else to track.

Worth knowing: most of the 100-plus published studies on pine bark used a specific French maritime pine extract standardized to 65–75% procyanidins, so the deepest evidence sits with that particular form rather than pine bark broadly. Those trials dosed 50–200mg, and your single 300mg capsule clears that range with room to spare.
