What is Pycnogenol, does it work, and is it the same as other pine bark extracts?
Pycnogenol (Horphag Research), a branded form of pine bark extract, is promoted for various uses — including improving circulation, cognition, joint pain, vision, symptoms of prostate enlargement, and other conditions — due to its antioxidant and anti-inflammatory properties. Some clinical research has suggested that Pycnogenol may be beneficial for some of these conditions, but many of the studies to date have been funded by the makers of Pycnogenol and some were small in size, which limits the impact of the results and has led some experts to conclude that there is insufficient evidence to recommend for or against Pycnogenol or other pine bark extracts for any uses (Robertson, Cochrane Database Syst Rev 2020; Schoonees, Cochrane Database Syst Rev 2012).

Note: Unfortunately, the current method of testing for compounds in Pycnogenol and other pine bark extracts can be easily fooled by the addition of tea catechins. Until a more reliable, validated method is developed, ConsumerLab.com is unable to test and review these products.
