What are Oligomeric Proanthocyanidins (OPC)?

Oligomeric Proanthocyanidins (OPCs) are plant polyphenols found in sources like grape seed and pine bark. They are known for antioxidant activity and support for blood vessel function.

What are the main benefits of OPC supplements?

OPCs are commonly used for antioxidant protection, cardiovascular and capillary support, and microcirculation. They’re also used to support skin elasticity and protection from oxidative stress.

What is a typical OPC dosage range?

Common supplemental amounts are about 100–300 mg per day, depending on the product and individual goals. Follow the label directions and consider medical advice if you have health conditions.

Can OPC help with circulation or swelling (edema)?

OPCs may support microcirculation and help strengthen small blood vessels, which can be relevant for swelling related to vascular function. Effects can vary by person and underlying cause.

Are OPCs the same as grape seed extract?

Not exactly—OPCs are a group of compounds, while grape seed extract is an ingredient that may contain OPCs. The OPC content can vary by extract and standardization.
