I am very pleased, so far, with the GNC L-Arginine. I was especially happy to find that it contains no stearates of any kind ~ hard to find these days.

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 will not cause heart palpitation?
A shopper on Nov 1, 2018
BEST ANSWER: I have not had any problems with heart palpitation from taking L-Arginine. I also take L-Citrulline with it. You can read about this combination in the book "No More Heart Disease" by Lou Ignarro. Hope this helps
