Oligomeric Proanthocyanidins (OPC)

OPCs are oligomeric proanthocyanidins from grape seed or pine bark, used for microcirculation, collagen stability, and heaviness in the legs.

Eases heaviness in the legs

Oligomeric proanthocyanidins can affect capillary permeability and venous return, so calf heaviness and ankle swelling after long standing are often milder. For people whose shoes feel tighter after standing at a counter or sitting through a long trip, a lighter feeling in the calves is more often noticeable after several weeks of continued use.

Supports collagen stability and skin

OPCs can cross-link collagen fibers and reduce oxidative burden on connective tissue; skin elasticity and capillary integrity are often watched together. For people who feel their skin is sagging or who easily show capillary marks, differences in firmness and evenness of tone are more often noticeable after several weeks of continued use.
