Enhance The Size Of Your Blood Vessels: Better nutrient delivery, rock hard pumps, and that hard, vascular look.*

Aside from consuming lots of lean red meat, supplementing with arginine alpha-ketoglutarate is one of the best ways to enhance the natural nitric oxide production capacity of your liver.1

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.*1

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*.1

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.1 Arginine, taken in combination with proanthocyanidins or yohimbine, has also been used as a treatment for erectile dysfunction*.

Increased Nutrient Delivery Means Better Health Both In and Out Of The Gym

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*.3 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.3

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*.2

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.*

Try it today and you just might just experience the rock hard pumps, increased vascularity, and enhanced muscle growth and recover that has made arginine alpha-ketoglutarate a staple supplement for some of the best body builders and athletes in the world.

    I just posted my recommendation for this product on a men’s health forum I help started and Moderate on at and gave it my highest recommendation and now added it to my NO stack. The fact that it’s L-Arginine in the Alpha Ketoglutarate forum, ultra micronized for higher bio-availability and pharmacy grade at this price is amazing. 5 Stars in my book.

    The retail price is a little high but this Arginine is the best GOOD QUALITY arginine I’ve found. Find them on a wholesale site for cheaper

    this supp was my first time taking arginine alone. you dont get a crazy pump up like jack3d or something but i would get the jitters really bad from jack3d. this gave me a really good pump but its not the same level as a “preworkout” with all the stims. I wasnt feeling sick or cracked out though so im definitely buying more for my new preworkout.

    Good stuff. I use arginine and caffeine for preworkout. Ive tried alot of different brands of arginine and nutrakey’s arginine is probably among the best. Some brands will underdose capsules or have poor quality arginine and you can tell when you take it. Took 3 of these bad boys before my workout today and vascularity was crazy.
