OPCs, also known as proanthocyanidins or procyanidins, are one type of naturally occurring plant compounds called bioflavonoids. The grape seeds used to produce grape seed extract are generally obtained as a by-product of grape juice or wine industry. As a potent antioxidant and free radical fighter, it is widely used in pharmaceutical, cosmetic and food industries.

Grape seed extract Benefit and Dosage

1. Antioxidant – free radical fighter

Antioxidants play a role in the management or prevention of some medical conditions, such as blood vessel disease, cancer and Alzheimer's disease. Grape seed extract is an excellent source of an antioxidant known as oligomeric proanthocyanidins (OPCs), which is 20 times stronger than vitamin C and 50 times stronger than vitamin E. It can protect the body from damage caused by harmful molecules known as free radicals. Many experts believe this damage is a factor in the development of some diseases.

Recommended Dosage —— 50-100 mg per day

In chronic venous insufficiency, blood pools in the legs, causing pain, swelling, fatigue, and visible veins. A number of studies have shown that Proanthocyanidins from grape seed can strengthen weakened capillaries and reduce symptoms. Proanthocyanidins are shown to protect collagen, one of the most important components of capillary walls.

Recommended Dosage —— 50 to 100 mg two to three times daily

3. High blood pressure

According to one study, grape seed extract significantly lowered both systolic and diastolic blood pressure in people with mild hypertension (mildly elevated blood pressure).

Recommended Dosage —— 300 mg per day
