NutraKey | Arginine


In short, nitric oxide one of the most effective natural compounds that can expand the size, elasticity, and carrying capacity of your blood vessels (vasodilation). This means that you won’t just look more vascular and feel a better pump with each rep, but your muscles will actually be getting more of the vital nutrients, amino acids, and the oxygen that they need to grow.

Look Great, Feel Better

In this way, the increased circulation and blood flow that may result from arginine supplementation may also speed up recovery time, increase energy levels, decrease blood pressure, and boost sexual performance.

As an amino acid (the building blocks of protein), arginine also plays an important role in cell division, the healing of wounds, removing ammonia from the body, immune function, and the release of hormones. Arginine, taken in combination with proanthocyanidins or yohimbine, has also been used as a treatment for erectile dysfunction.


Arginine is also popular in the medical community to help combat kidney disease, digestive problems, liver issues, and even cataracts by increasing the amount of nutrients available to muscle and improving waste removal from muscle and healthy tissue. For athletes, arginine supplementation may assist with the breakdown and removal of exercise-related waste products in the liver such as ammonia – potentially decreasing soreness, fatigue, and recovery time.

Evidence also shows that arginine may even help stimulate protein synthesis, growth hormone, and insulin production – all of which will theoretically increase both muscle size and strength.


Don’t Flush Your Arginine (And Money) Down The Drain Unlike regular l-arginine, arginine alpha-ketoglutarate by Nutrakey has been specially developed for maximum bioavailability and absorption by the body. While normal l-arginine largely isn’t available for use by your liver, arginine alpha-ketoglutarate is perhaps the most effective delivery system for sustained nitric oxide production.

These work!

My father came to me with an expressed interest in N.O. he was looking around and everything seemed a lot more expensive. I told him that he should look in to arginine. Surfing the website I found this. It's reasonabley priced. Instructions are simple and you get 100 caps per bottle! I'm a firm believer you shouldn't have spend a ton of money on supplements. I purchased 3 bottles 2 for pops and one for myself. I noticed after taking these for a few weeks, my veins are a bit more vascular, I've increased my maximum out put on my workouts. Even my dad is excited, he had his best ride of the year so. He just turned 61 and killed his 41 mile bike ride. He's training for a century (100 mile) ride and he credits the ride to the supplements. Best bang for your buck right here! Highly suggest you get this if your looking to get a n.o. boost!

Tiger Fitness will not be undersold on this fantastic product, or any other product for that matter. I can really feel the energy and my wife says I do not get as agitated as before due to the effects of this product on my body. Again, you cannot beat the price and quality of this product anywhere. Thanks Tiger Fitness.
