I wanted to pass along my finding that taking L-carnitine with Viagra or Cialis appears to improve the effect of these drugs. The great thing about L-carnitine is that it is very safe (for most people – talk to your physician before taking anything) and has virtually no side effects that I can detect (although I’ve been a little itchy recently…) It’s also not expensive.
If I were Pfizer or Lilly, I would give free carnitine with every prescription of Viagra or Cialis…
The research I uncovered used proprionyl-L-carnitine, but L-carnitine seems just as good. You can get it at any vitamin shop or drug store, or on-line (no prescription needed). I take 1000 mg/day (500 mg, twice a day), although some studies discuss 2 g (2000 mg) per day. Like some other agents, it may be good to use it for a while and then stop for a few days. I can’t say how quickly it works, but I get the sense that it works pretty quickly (say, within 1 hour). I take it at night and in the morning (500 mg BID).
I’ve posted references on this before, but here’s two more:
Life Extension Newsletter (CLICK HERE)They offer it for sale but you can probably find it for less in your local drug store. If anyone knows a cheap place to buy L-carnitine, let me know.
