Over 65 years of science on their remarkable benefits to human health.

MASQUELIER's® OPCs ingredients have been studied for over 65 years and are renowned for their powerful health benefits that help support collagen, elastin and the vascular and immune systems. OPCs were first discovered by Professor Masquelier who was also the first to extract them. He dedicated his life to developing OPCs ingredients that would have the greatest benefit to human health. Still produced and authenticated by his original company, they are now protected by the MASQUELIER's® mark.




By helping protect, strengthen and promote the growth of collagen and elastin, MASQUELIER's® OPCs ingredients support the body's vascular system. This system is at the heart of good health, as it delivers nutrients and oxygen to every part of the body. It also performs the important task of waste removal. By supporting the healthy functioning of this essential system, they support many areas of human health.

Professor Masquelier's ultimate evolution of OPCs

Professor Masquelier was the first person to successfully isolate and extract OPCs. After many years of intensive research, he not only found that OPCs are not all the same, they come in many different sizes, and form many different compositions that have different effects on human health. He dedicated decades to developing the ultimate compositions of OPCs now identified by the MASQUELIER's® trademark. They are still authenticated at every stage of their production by a group he set up to uphold their unique composition and quality. He spent the rest of his life researching their remarkable impacts on health.


What are OPCs?

OPCs (short for oligomeric proanthocyanidins) are a group of naturally occurring compounds with important health benefits. OPCs are completely natural, and perform a number of known functions in the human body, although the body itself cannot produce them.  They are a special type of proanthocyandin, which is a chemical compound that helps protect plants. Professor Masquelier was the first to isolate and identify them. He named them OPCs and only included the very smallest kinds in his definition. He did so as these are the ones most active and bioavailable ... the ones that the body can process and are therefore of most nutritional value.
