Have Used L-Arginine 1000mg for a decade
I started using this product in my daily supplementation about 10 years ago after reading Ray Kurzweil's Fantastic Journey. I take 2 caplets in the morning and 2 at night. I experienced the problem described in some reviews of crumbling caplets when I traveled to Mexico, having put the caplets in a large baggy with all my other supplements. Whether it was the heat or the humidity, I can't be certain, but my solution was to make small daily dose packets (one for morning, one for night) in ziploc poly bags that I got at a hardware store. I make up the packets before I leave on a trip - it takes no more time than sorting through a large bag hunting for the various supplements, and it keeps everything fresh. It's difficult to prove the product is keeping my vessels flexible, but my blood pressure is excellent so I believe it works.

This product works just like it's supposed to. I could feel the difference when I first started taking it, although now I take it every day. But when I ran out some weeks ago, I felt the difference! Great product. I cannot swallow the caplets, but the capsules are fine. I get it on Auto Ship. I recommend this to anyone instead of "beet juice" which is more expensive.
