NSI L-Arginine & L-Ornithine -- 2,000 mg - 300 Capsules

How Does NSI® L-Arginine & L-Ornithine Work? L-Arginine & L-Ornithine is a combination of two closely-related amino acids in one supplement. L-arginine is a semi-essential amino acid which plays an important role in cell division, the healing of wounds, removing ammonia from the body, immune function, and the release of hormones. L-Ornithine is a nonprotein amino acid which the body uses in the biosynthesis of L-arginine. NSI® L-Arginine & L-Ornithine is better because it:. Comes in 2,000 mg per serving. . Did You Know? All NSI supplements are packaged in HDPE (High Density Polyethylene) bottles. These bottles keep moisture vapor out, protecting the freshness and integrity of their contents, and are 400% more effective compared other brands currently using PET (Polyethylene Terephthalate) bottles. HDPE bottles do not break as glass can and are also recyclable so we urge you to please recycle them.

"I have been taking this stuff before running, cycling and lifting. I'm very in tune with my body, and my level of fatigue after different levels of exertion and on different diets/supplements. Simply adding this to my routine (3 pills, 20-30 minutes before I start) gives me more endurance, stamina and leaves me feeling less fatigued/sore during and afterwards. These are now a staple of my supplementation."

"I take quite a few supplements for my workout (creatine, glutamine, whey proteins, arginine + ornithine). All of them together have completely ripped me up and helped me gain a little mass that i was looking for. I added the arginine because I take a lot of protein and it helps with the synthesis and transport of proteins. Good stuff!"

"I've taking L-Arginine separately for months and never really so much results. I thought I'd try this combo formula and I was quite surprised at it's effectiveness. If you looking to put a little more lead in your pencil, this stuff really works."

"If your searching for the supplement that keeps you coming back for more bodybuilding workouts day after day this is the product for you. This product is great at keeping muscle mass on you when go on vacation etc. as well. If you are a hard gainer this will help you keep the muscle mass that you worked so hard to get. I don't know if I would recommend the serving size of 3 capsules, if I take that many I start to become nothing but veins. Therefore, I lowered my dose to 2 capsules a day, and I am not having the vein issue anymore. In my opinion the L-Arginine & L-Ornithine combination works far better than just buying the L-Arginine alone."

"I've been taking this product for about 2 months now, and I have noticed better circulation. I used to get extremely cold in the winter months especially my hands and feet. Taking the product has definitely helped!

I've also noticed a difference in my muscle tone. As someone who is quick to loose muscle tone, I seem to retain more tone after workouts using this product."

"I first learned about L-arginine and L-ornithine as a trainer for a major sports program in the 70s. The properties of these 2 amino acids in vaso-dilation and natural production of human growth hormone has helped me maintain normal blood pressure, cholesterol, and a healthy love life at age 65. L-arginine has been called "nature's viagra". I feel every on the planet over 40 should take it."
