This extract comes from red grapes grown in France using traditional viticulture methods, respecting the vine’s natural cycle. Each capsule contains the concentrated equivalent of 15 grams of grape seeds, thanks to a 150:1 extraction ratio, among the highest on the market — it takes 150kg of dried seeds to produce just 1kg of finished extract. A gentle double-extraction process preserves the integrity of the polyphenols while reaching an exceptional 96% concentration of total polyphenols. The raw material is non-GMO and grown with attention to ecological impact, with full traceability from field to finished product.

Oligoproanthocyanidins (OPC) are the most active fraction of grape polyphenols, recognised for their ability to neutralise the free radicals responsible for premature cellular ageing. This extract’s ORAC index exceeds 19,000 micromoles TEQ/g, making it one of the most powerful measurable natural antioxidants. Its OPC profile includes procyanidins B1, B2, C1 as well as epicatechins and catechins — a full molecular spectrum providing broad cellular protection against everyday oxidative stress.

Grape OPC has a well-documented effect on blood vessel health, improving the elasticity and suppleness of small capillaries, reducing vascular fragility, and supporting circulatory comfort in the legs — particularly appreciated by people who experience heavy legs or spend long periods standing. On the cardiovascular side, grape polyphenols help protect against LDL cholesterol oxidation and support healthy blood pressure when combined with a suitable lifestyle. Unlike many classic antioxidants, the OPC monomers in this extract also cross the blood-brain barrier effectively, giving them direct access to brain and eye tissue where they exert their protective properties — of interest to anyone wishing to support memory, mental clarity and visual acuity.

Recommended dose is one capsule a day, preferably with a meal to optimise assimilation. A course is particularly useful during seasonal changes, increased sun exposure, or as part of an anti-ageing routine. Grape seed extract pairs well with marine omega-3 for cardiovascular support, collagen for skin elasticity, or natural vitamin C to complete the antioxidant effect.

Under normal conditions of use, grape seed extract does not cause major adverse effects in healthy adults. Prior discussion with a healthcare professional is nevertheless advised for those on anticoagulant treatment or with a bleeding disorder. Food supplement. Not a substitute for a varied, balanced diet and a healthy lifestyle. Do not exceed the recommended daily dose. Keep out of reach of children.

Why choose a French grape seed extract?

A French extract relies on a well-controlled local supply chain, responsible farming and a harvest timed for grape maturity. France applies strict safety and quality standards that ensure full traceability and optimal preservation of the actives, while short supply chains reduce the ecological footprint.

How long does a bottle of 60 capsules last?

At one capsule a day, the 60-capsule bottle covers two full months of supplementation. For lasting results, many people continue the course over several annual cycles, particularly during periods of fatigue, increased oxidative stress, or intense sporting effort.
