Thorne Grape Seed Extract
Every hard training session generates free radicals — reactive molecules that damage cell membranes, blood vessel walls, and connective tissue if your antioxidant defenses can't keep up.
Most athletes think about antioxidants in a vague, general sense. Thorne Grape Seed Extract makes the case more specifically: the oligomeric proanthocyanidins (OPCs) concentrated in grape seeds have a documented affinity for vascular tissue and connective tissue — the exact structures that endurance athletes beat up most.
This is targeted antioxidant support, not a general wellness supplement.
Phytosome Delivery – Most grape seed supplements use raw OPC extract that your body absorbs poorly. Thorne binds its OPCs to phosphatidylcholine — a phospholipid found naturally in cell membranes — so significantly more of the active compound actually reaches the tissues that need it.
Vascular Protection Where It Counts – OPCs protect the lining of your blood vessels from exercise-induced oxidative damage — the same tissue responsible for nitric oxide production and blood flow regulation. Protecting it daily supports the long-term vascular health your endurance performance is built on.
Stronger Connective Tissue, Less Bruising – OPCs have a natural affinity for collagen and elastin, the proteins that give tendons and ligaments their strength. Clinical studies in athletes show reduced swelling and faster recovery from sports injuries when OPCs are supplemented before competition, with less bruising thanks to reduced capillary permeability.
What Is This About OPCs?
They are among the most potent plant-derived antioxidants available — with some research suggesting greater free-radical scavenging capacity than vitamins C and E. They neutralize reactive oxygen species, bind iron and copper to reduce their oxidizing effects, and protect cell membranes from injury. The phytosome delivery in this formula ensures that potency is actually delivered to the tissues that need it.
How to Use Thorne Grape Seed Extract
Dosage: Take 1 capsule two to three times daily with food. Consistent daily use builds a baseline of OPC coverage that benefits both acute training sessions and longer-term vascular and connective tissue health.
