You could also look at OPC's namely: grape seed extract and or pycnogenol. I'm headed into 20 yrs on these OPC's...for my total immune system. I've never had the "fog" issue as many report with so many health issues...OPC's work on our total circulatory system from head to toes....

I have a post on the vitamins/supps section here on OPC's...I'm huge on Coconut Oil, use it for everything.
