The extract is part of the result
Pine bark extracts are sold as capsules, tablets and powders. They vary in plant species, procyanidin content and added ingredients, which complicates comparisons between products. Pycnogenol is standardized to about 70% procyanidins; a generic pine bark label does not identify an identical preparation. 1 2
How much has been studied?
The skin trial used 100 mg per day, divided into two doses. That is a description of one study, not an established daily requirement or a general dose for blood pressure, joint symptoms or other concerns. The wider review included different preparations and treatment schedules. 2 3
