Where does pine bark extract come from?
Maritime pine grows along the coasts of south-western Europe, particularly in France. The bark is harvested, ground and extracted with water to concentrate its natural compounds.
What are procyanidins?
Procyanidins (also called proanthocyanidins or OPCs) are flavonoids also found in grape seeds, cocoa, apples and cranberries. Pine bark extracts are often standardised to a percentage of procyanidins. See Extract Ratios and Standardisation Explained.
