in my life since I started on Pycnogenol in 1995, then after a year went to grape seed extract. Long history and I could write my own book, but here is a good site to learn about OPC's if you don't have the history of them. Just too too bad, they could not save me from a hip replacement which has been a huge downfall for me since late 2010. Nice to be here and learn more and support others with all I've learned in the last 25 yrs on my alternative healing path.
