This is a great overview of OPC's...I'm headed to my 20th yr taking OPC's...pycnogenol and grape seed extract are my "miracle workers"....I am not using/endorsing this company's product but like their info. MANY vit companies sell OPC's.

Personally, I never had circulation issues until I had hip replacement in 2010, and left with many complications; one major one, cutaneous femoral nerve damage...going on 5 yrs soon.

My main reason for starting on OPC's in 1995, we were told it MAY prevent cancer....so I jumped on Pycnogenol. Then went to grape seed ex and shortly after on Pyc, a lifetime of allergies/sinus issues cleared up big time....there are MANY benefits to OPC's..
