Grape seed extract (Vitis vinifera L.; 50% oligomeric proanthocyanidins (OPC)), anti-caking agent: calcium carbonate, coating agent: hydroxypropylmethylcellulose (capsule shell), camu camu fruit extract (Myrciaria dubia; 25% vitamin C).
OPC Grape Seed Extract Capsules by Natura Nova provide 250 mg OPC (oligomeric proanthocyanidins) per capsule – combined with natural vitamin C from camu camu. Vitamin C contributes to the normal function of the immune system and to the protection of cells from oxidative stress. Storage and shipping are handled directly from Switzerland.
OPCs are secondary plant compounds from the flavonoid family, naturally found in grape seeds as well as in berries and pine bark. Grape seed extract is considered one of the best-known and most concentrated sources of OPC and has been studied in nutritional science for decades. Camu camu (Myrciaria dubia) is a South American berry and one of the richest natural sources of vitamin C. Unlike synthetic ascorbic acid, the vitamin C in our capsules comes exclusively from this plant.
OPC and its main active compounds, the oligomeric proanthocyanidins, are the subject of current nutritional research – you can find a detailed overview in our plant knowledge article.
For Natura Nova OPC Capsules, a standardised grape seed extract is used to ensure a reproducible OPC content of 250 mg per capsule. Manufacturing takes place in a GMP-certified facility. Each batch is laboratory-tested for purity, identity and microbiological parameters. The vegan HPMC capsule shell is free from animal-derived ingredients.

What is OPC?
OPC stands for oligomeric proanthocyanidins—secondary plant compounds found in grape seeds. These capsules contain a standardized grape seed extract from Vitis vinifera with a 50% OPC content.
What is the difference between OPC and grape seed extract?
Grape seed extract is the raw material; OPC is the active ingredient it contains. Each capsule contains 500 mg of grape seed extract, of which 250 mg is OPC.
Where does the vitamin C in these capsules come from?
The vitamin C comes from natural camu-camu fruit extract (Myrciaria dubia), not from synthetic ascorbic acid.
