What Are OPCs and Where Do They Come From?

Oligomeric Proanthocyanidins (OPCs) are a unique class of powerful plant-based antioxidants. They belong to the flavonoid family and are especially abundant in:

• Grape seeds
• Pine bark
• Chokeberries (Aronia)
• Red wine
• Cocoa and certain berries

OPCs are made up of catechin and epicatechin monomers, which combine into dimers, trimers, and larger oligomers. Their low molecular weight makes them highly bioavailable, allowing them to penetrate cell membranes and deliver protection at a cellular level.

Why OPCs Are Among the Most Potent Antioxidants

OPCs are known for their strong free radical scavenging activity and broad cellular support. Their unique properties allow them to:

• Cross the blood-brain barrier to support brain and cognitive function
• Support collagen and elastin integrity in skin and joints
• Promote blood vessel elasticity and healthy circulation
• Help balance oxidative stress and support a healthy inflammatory response

This makes OPCs ideal for supporting skin vitality, cardiovascular function, cognitive clarity, joint comfort, and immune resilience.
