Has anyone else figured out what vasodilators, such as the amino acid L-Arginine and the vitamin Niacin (B3), will do for many middle-aged men? It will make them feel years younger... in bed... No joke... these are common ingredients in erectile dysfunction (ED) dietary supplements aka neutraceuticals:
http://www.ncbi.nlm.nih.gov/m/pubmed/21966881/
"These preliminary findings indicate that the favourable cardiovascular effects of nutraceuticals might also reflect on male sexual function with possible implication in the treatment and prevention of ED. This study documents a considerable patient's interest toward nutritional supplementation--as first-line or adjunctive treatment to PDE5 inhibitors--that goes beyond the measurable increment in penile rigidity."

This already is a *huge* market that will simply increase as baby boomers age... and the supplement market will increase as states and private insurers stop covering ED drugs... the three top drugs alone brought in over 3 billion in 2006...

...and put the ingredients in a discreet, ready to go beverage instead of having to buy them in a ED supplement pill at the health food store counter... vasodilators also increase libido in women as well...

...and I'm waiting to see if this information gets removed from iHub, as it has several times before... you'd think a review of ingredients would be considered on-topic...
