Grape seed extract is derived from the ground seeds of red grapes and is rich in oligomeric proanthocyanidins (OPCs)—potent antioxidants known for supporting vascular and cellular health. In sports nutrition, it is valued for its ability to improve circulation, protect against oxidative damage, and aid recovery from intense training.
This extract is particularly useful in supporting cardiovascular function, reducing inflammation, and improving blood flow, which may enhance nutrient delivery to muscles during exercise. Additionally, its antioxidant properties may support faster recovery and reduced soreness.
Grape seed extract is often found in recovery formulas, heart health supplements, and anti-aging blends due to its wide-ranging effects.
