"This combination really helps in my workouts with lots of endurance at a great price." ~product review by Eternalsage

  • A popular free-form amino acid two-some supporting overall health

  • This nourishing combo delivers renewed vitality without denting your pocketbook

  • Helps promote lean muscle

Life extension enthusiasts, body builders, and natural health proponents have been telling the world of this amino acid combination for quite a few years now, and the science is catching up to their claims. Arginine is integral to the production of nitric oxide. It's an important natural substance involved with everything from cardiovascular function to muscular energy. Ornithine metabolizes to arginine in the body, and it has its own unique, nourishing influence on the body. Our L-Arginine & L-Ornithine brings you the proper two-to-one combination in free form for optimum results.

Good Purchase This is a feel better product for me. The increase in blood flow is great. Increases my workouts with less fatigue. January 3, 2014
Great help I started taking this to help me sleep with some Melatonin. It really helps me enter a nice deep sleep and not have that 3 am wake period that so plaques menopausal women. Your product seems to work better than another popular vitamin store brand and it is cheaper. Thanks for the restful sleep. August 8, 2013
