“Eat the rainbow!” We’ve all heard this (very good) dietary advice, but have you ever thought about why color is so important? It’s the phytonutrients! These compounds give plants their color, but they also provide protection from pests, diseases, and other environmental stressors; built-in defense systems, if you will. Phytonutrients also appear to provide similar protections to humans when we eat them or take them as supplements, promoting health and reducing the risk of chronic disease. You’ve probably heard of flavonoids, polyphenols, and carotenoids—these are all types of phytonutrients—but then there are some that aren’t as familiar, like oligomeric proanthocyanidins, or OPCs. OPCs are a very specific type of polyphenol found in high concentrations in grape seeds and certain types of pine bark (Pycnogenol ® is a trademarked name). They have a unique chemical structure that allows them to easily pass through cell membranes, making them more bioavailable compared to some other types of polyphenols, contributing to their powerful health e ects. With antioxidant activity 50 times greater than vitamin C, they protect cells from oxidative damage and have a special a nity for the blood vessels, helping to strengthen the arteries, veins, and capillaries, reducing the risk of a myriad of health problems that may arise from a weak or damaged vascular system, from the uncomfortable (hemorrhoids) to the serious (stroke). Through their positive effects on the vascular system, grape seed extract and Pycnogenol support whole-body health, from cardiovascular and brain health to skin health.
