I’ve been doing some research in this area myself and thought I would share some thoughts with everyone. As most of us here knows, arginine is the direct precursor to nitric oxide. Viagra, Cialis, and Levitra inhibit the enzyme cGMP to keep nitric oxide “alive” longer. The production and release of nitric oxide is controlled by the enzyme nitric oxide synthase.
There are some good studies showing that pomegranate,blueberry, and dark chocolate, by virtue of their flavanoid content, increase the activity of NOS and thus raise NO levels. Pomegranate especially, has been shown to increase NO levels by 50% in cardiac tissue. Whether this occurs in the CC is not known at this time but the speculation is interesting. Panax ginseng has been shown to raise NOS/NO levels in the rabbit CC due to it’s polysaccaride content. One wonders if taking arginine,eating certain foods, taking ginseng, and using Viagra would have a marked effect on potency.
Hope this is helpful or at least interesting to members of the forum.
