Swanson Superior Herbs Pine Bark Extract provides 50 mg of pine bark extract per capsule, standardised to 95% OPC (oligomeric proanthocyanidins) concentration. Each bottle contains 100 capsules, making it a well-priced option from a brand with a long-standing reputation for quality herbal supplements.
Oligomeric proanthocyanidins are naturally occurring compounds found in pine bark and are the defining feature of this extract. The high standardisation level means each capsule delivers a consistent concentration of OPCs, which is something to look for when comparing botanical supplements.
The capsule format is easy to take alongside food or drink and requires no measuring or mixing. This product is well suited to those who prefer their supplements in a simple, unflavoured capsule rather than a powder, and to anyone looking to add a concentrated pine bark extract to their existing nutrition routine.
