Rated 5 out of 5 by from LEAN MUSCLES Going back to the '70s I have taken L-Ornithine along with L-Arginine when working out. Today I take 5 grams of Swanson's AKG Arginine Lemon Flavored Powder daily, so I take 2 grams (4 capsules) of L-Ornithine along with it. I don't mind taking my L-Ornithine in capsules, because it tastes terrible. I wouldn't want it in powder. The Arginine powder tastes fine, actually pretty neutral even without the lemon flavoring plus the xylitol and stevia natuaral sweeteners. Personally, I have always felt that L-Ornithine is a partner with L-Arginine. Sort of like Fred Astaire and Ginger Rogers. A lot of people think that Ginger was even better than Fred, because she did everything he did backwards and in heels. So is L-Ornithine better than L-Arginine? No, I don't think so. They are complimentary team mates. I like my results when I take 2 grams L-Ornithine daily.
