Changing the Face of Antioxidant Protection

In 1948, Professor Jack Masquelier helmed a scientific breakthrough when he successfully isolated the powerful antioxidants Oligomeric proanthocyanidins (OPCs). OPCs are not naturally generated in the human body, nor can they be synthetically produced. Decades of research went into his revolutionary technique of extracting OPCs from Grape Seeds for therapeutic use. OPCs provide phenomenal antioxidant action to noticeably help support healthy circulation, the cardiovascular system, and hair, skin and nails. As a potent free radical scavenger, OPCs can reduce inflammation and associated tissue damage.

Decades of research

Professor Masquelier spent his entire scientific career developing, perfecting and researching OPCs, known as MASQUELIER’s® Original OPCs. There have now been multiple clinical trials investigating the benefits of the patented Grape Seed extract in Anthogenol®, focusing especially on their benefits for the symptoms of varicose veins*

OPCs appear in nature in many different forms with varying degrees of efficacy, however they are most highly concentrated in the woody parts of plants. Professor Masquelier developed an exacting, patented method to extract this powerful antioxidant, which lead to the development of Anthogenol® – a highly refined form of Grape Seed extract that cannot be compared to any other on the market.
