Cocoa flavanols can increase nitric oxide synthase activity, potentially explaining blood pressure reduction when combined with homocysteine-lowering strategies.

“because when you directly inhibit nitric oxide synthes in the endothelium you are preventing the creation of nitric oxide and of course that's what coca flaven oils actually do the opposite of that so I think the one two punch of lower Ing homocystine and raising uh nitr oxide synthes activity via coca flavanol could could certainly explain a reduction in blood pressure”
