Grape Seed Extract

Grape seed is one of nature's richest sources of OPCs, those lovely antioxidants from the seeds and skins, and the standardization tells you how much you're really getting. Ours is 90%, so 270mg of every 300mg tablet is the good part, not plant bulk. Vegan, non-GMO, clean and third-party tested, with the active content right on the front so you can compare it against anyone.

Proudly made in the USA and the UK to the strictest of standards

Among the richest natural sources of OPCs

Grape seed extract is valued for its OPCs, potent flavonoid antioxidants concentrated in the seeds and skin of the grape. The point of buying an extract is that most of what you swallow is active rather than plant bulk, which makes the standardization percentage the number that decides quality. Ours is standardized to 90% oligomeric proanthocyanidins, so each 300mg tablet delivers 270mg of OPCs, near the top of the market.

Standardized to 90%: 270mg of active per tablet

A tablet standardized to 90% is a different animal from a vague 'grape seed 300mg' claim, because it tells you exactly how much of the antioxidant compound is present. We put that figure on the front, since it's the only honest way to compare one grape seed product against another.

Vegan, and verified by an outside lab

It's cGMP-certified with clean binders, vegan-friendly and non-GMO, free of artificial colours and filler. An independent lab confirms the OPC standardization and screens each batch for contaminants, with the exact active content stated openly.
