2x Daily for Prime Performance

Take 2 before you head to the gym. Take one before work, one before you head out to class, or to your Peloton®. You decide. Two capsules daily is all you need for safe and effective Nitric Oxide support.


As a powerful vasodilator produced within the body, Nitric Oxide (NO) may be the most important molecule for physical performance. Dietary support of nitric oxide production is a well-established performance-enhancing strategy. * It helps open the blood vessels and capillaries for optimum blood flow, increasing circulation and oxygenation to the muscles.* It’s as true for your heart and lungs as it is for your biceps and deltoids.* The key is to do it safely. Sports IllustratedTM Nutrition’s Nitric Oxide formula has your back with a precision blend of ingredients scientifically validated to stimulate and support optimum NO production, naturally.*

L-Arginine is the direct precursor to this powerful vasodilator, increasing blood flow to the muscles.* Combining it 2:1 with L-Citrulline helps the body use NO to its fullest potential.* Alpha-ketoglutarate (AKG) promotes cellular energy production, supports protein synthesis, and inhibits protein degradation in muscles, opening the channels for extreme energy and physical performance.*

  • Includes supporting herbs not found in other supplements
  • Garlic, Ginger & Cayenne Pepper to boost Nitric Oxide levels*


Inside the Bottle

Because it’s what’s inside that counts

Collapsible content

Arginine Hydrochloride & Arginine AKG

L-Arginine is the direct precursor to the powerful vasodilator nitric oxide*. Alpha-ketoglutarate (AKG) promotes Kreb’s Cycle energy production.* Together they deliver a potent one-two punch to amplify the body’s production of nitric oxide.*

L-Citrulline helps the body use NO to its fullest potential. SPORTS ILLUSTRATED™ Nutrition’s Nitric Oxide formula opens the channels for extreme energy and physical performance.*


L-Citrulline helps the body use NO to its fullest potential.* As a precursor to L-arginine production, this amino acid has its own value as an amino acid.* Evidence suggests L-citrulline may be involved in the formation of certain proteins in addition to its direct and indirect effects on vasodilation and NO synthesis.*

Ginger Root

Primarily known for its stomach-soothing qualities, ginger is much more. It’s a well-recognized herb for testosterone support and stress management.* Evidence suggests that ginger compounds may work through a mechanism of action that involves the stimulation of NO production.*


Garlic is widely revered as a cardioprotective food.* It turns out that among its other amazing benefits, garlic contains compounds known to activate nitric oxide synthase, the enzyme that aids in the arginine-to-NO conversion.*


Maximum pump. Ultimate endurance. Superior strength. Healthy levels of nitric oxide are recognized for supporting all of these objectives.* Athletes at all levels look to the ingredients in SPORTS ILLUSTRATED™ Nutrition’s Nitric Oxide formula for support. We simply put them together in the most powerful NO supplement you can trust for safe, reliable results.*


Maximum pump means maximum power. Maximum oxygenation and nutrition means maximum gains. NO-enhancement is a common strategy made simple with SPORTS ILLUSTRATED™ Nutrition’s Nitric Oxide formula.*


The effect of Nitric Oxide on the cardiovascular system and the oxygenation of muscles and tissues make it the “miracle molecule” for endurance athletes and anyone looking to boost their stamina throughout the day.* Well-nourished muscles recover faster and build stronger tissue, giving you the power to keep going for the long term.*


Circulation. Blood pressure. Oxygenation. Without these functions, muscles don’t matter. They don’t exist if you’re an aerobic athlete, you need that oxygen and circulation support as well. Whether you’re an average Joe, a weekend warrior, or an aerobic athelte, you can benefit from optimized NO production. SPORTS ILLUSTRATED™ Nutrition’s Nitric Oxide formula is for everyone who wants to experience the most life has to offer.*
