OPCs are primarily known as ingredients in skin care products, providing benefits both from the inside and out: In herbal medicine, grape seed extract is believed to have antioxidant and collagen-forming properties.
Additionally, OPC is believed to offer numerous other health-promoting benefits. The health claims in relation to OPC have not yet been conclusively evaluated. However, due to the number of studies, the efficacy described here can be sufficiently substantiated.
In humans, polyphenols like OPC are linked to a reduced risk of various diseases. [1] [2]
Oxidative stress, caused by free radicals, can accelerate the appearance of signs of aging. Although the body is equipped with complex protective mechanisms, oxidative stress occurs when the balance between free radicals and these defenses is disrupted due to factors like overload, environmental toxins, cigarette smoke, and alcohol [3]. When the damaging effects of free radicals outweigh the protective mechanisms, oxidative stress results.
Vitamin C is well-known as a potent antioxidant that may help protect our body’s cells from oxidative stress caused by free radicals, potentially slowing the aging process of cells.
The effects of vitamin C on the human body have been scientifically examined and confirmed by the European Food Safety Authority (EFSA). [4]

Several studies suggest that OPC from grape seed extract also has powerful antioxidant properties:
For example, one study shows that OPC can achieve a 78 to 81 percent inhibition of oxidants and free radicals at a concentration of 100 mg / l. [5]
Another study found that OPC grape seed extract capsules have an antioxidant effect that is at least equal to, and sometimes even stronger than, that of pure vitamin C, E, or beta-carotene. [6]
OPC Vital, combined with vitamin C, supports normal collagen formation, contributing to normal skin function. [4] This makes it the perfect support for maintaining youthful, elastic, and smooth skin, while also helping to combat premature skin aging.
According to studies, OPC also has circulation-promoting [7] and blood vessel-protecting [8] properties. As a result, it can help improve the supply of nutrients and oxygen to the blood vessels. Through the blood vessels, skin cells are supported in the production of fibrous proteins like collagen.
Together, OPC and vitamin C support the skin and connective tissue as "cosmetics from within".
Vitamin C can help prevent premature ageing processes in various ways. The EFSA's research revealed, among other things, that vitamin C contributes to:
- normal functioning of the immune system,
- normal functioning of the blood vessels,
- normal functioning of bones and cartilage,
- normal functioning of the gums and teeth,
- normal functioning of the nervous system and psyche,
- reduction of fatigue and tiredness.
- protection of cells from oxidative stress.
When the recommended daily intake of OPC Vital is followed, no side effects are generally expected. The product is not recommended for pregnant women.
