  • Arginine

    First, NO2® provides a potent dose of Arginine-AGK delivered with its clinically tested delivery technology.

  • NOS-Enhancing

    Second, the revolutionary "NOS-Enhancing" peptide fraction up-regulates nitric oxide synthase (NOS) and increases your nitric oxide levels by up to 950%.

  • Alpha-Lipoic Acid

    Third, the NO2® formula includes alpha-lipoic acid, designed to boost your insulin sensitivity and nutrient uptake. Simply put, the NO2® formula is an advanced nitric oxide generator.


Nitric oxide levels once had a pre-set limit - until NO2® that is! You see, nitric oxide (NO) generators provide your body with arginine - the building block of NO. But it's the NOS enzymes inside your body that convert the arginine into NO. In fact, NOS is the rate-limiting factor in NO production. Enter NO2®! NO2® contains ACTINOS®, the NOS-enhancing peptide fraction that's lab tested to increase NOS activity and boost nitric oxide levels by up to 950%.

As the chart depicts, regular arginine goes in and out of your system. Extended-release AAKG sustains nitric oxide levels over time. But NO2® can provide even more nitric oxide per gram of AAKG/ARG!*

In vitro research showed nutrients in MRI NO2® increased NO production in the tested cell cultures by up to 950%, which may result in a nitric oxide potential of 950%.

NO2 Pills Chart

Unleash the full potential of your workouts with MRI Performance NO2 Nitric Oxide Pills, a meticulously formulated supplement designed to enhance nitric oxide production and boost your exercise performance. The synergistic blend of key ingredients, including L-Arginine Alpha-Ketoglutarate 2:1 (A-AKG), L-Arginine HCL, Alpha-lipoic acid, ACTINOS (CFM Nitro), and Quercetin, works in harmony to maximize your athletic capabilities and promote overall cardiovascular health.

Key Ingredients and Their Synergistic Benefits

L-Arginine Alpha-Ketoglutarate 2:1 (A-AKG): A potent precursor to nitric oxide, A-AKG enhances blood flow to the muscles, promoting nutrient delivery and oxygenation. This key ingredient sets the foundation for an efficient nitric oxide boost.

L-Arginine HCL: Complementing A-AKG, L-Arginine HCL further supports nitric oxide production, leading to improved vasodilation. This enhances blood circulation, delivering more oxygen and nutrients to active muscles during exercise.

Alpha-Lipoic Acid: Known for its antioxidant properties, alpha-lipoic acid helps neutralize free radicals, supporting overall cellular health. By reducing oxidative stress, it contributes to a conducive environment for sustained nitric oxide synthesis.

ACTINOS (CFM Nitro): This innovative compound derived from whey protein isolate is scientifically proven to boost nitric oxide levels. ACTINOS works synergistically with other ingredients, enhancing the vasodilatory effect and promoting efficient nutrient delivery to muscles.

Quercetin: A flavonoid with anti-inflammatory properties, quercetin complements the nitric oxide-boosting effects by promoting cardiovascular health and aiding in recovery. Its synergistic role enhances the overall impact of the formula.

How They Work Together

Nitric Oxide Boost: A-AKG, L-Arginine HCL, and ACTINOS work in tandem to increase nitric oxide production, supporting vasodilation and improving blood flow for enhanced nutrient delivery and oxygenation.

Nitric Oxide Boost: A-AKG, L-Arginine HCL, and ACTINOS work in tandem to increase nitric oxide production, supporting vasodilation and improving blood flow for enhanced nutrient delivery and oxygenation.

Antioxidant Support: Alpha-lipoic acid and quercetin contribute antioxidant support, helping combat oxidative stress induced by intense workouts, promoting overall cellular health.

    I've been using NO2 from MRI Performance for some time now, and it far surpasses any beet juice or Super Beets, both of which are quite popular in the fitness world. My experience with this product dates back to 2008, and I recently started taking it again to support my blood pressure and cardiovascular health. As someone who has dealt with significant cardiovascular damage from past heroin addiction, NO2 has been incredibly beneficial. Since resuming NO2, I’ve noticed a significant reduction in anxiety and incredible muscle pumps. Unlike many, I steer clear of pre-workout supplements and caffeine. The natural boost from NO2, without any added stimulants, makes it a vital part of my routine In my opinion, NO2 delivers better results than beet-based products. While beet juice and Super Beets have their merits, NO2 offers a more effective and immediate impact on my cardiovascular health and workout performance. My Overall Impression NO2 by MRI Performance is a must-have for anyone seeking to improve their cardiovascular health and enhance workout performance without relying on stimulants. I highly recommend this product and will continue to share its benefits with others. Whether you’re managing specific health issues or simply aiming to elevate your fitness routine, NO2 is an excellent addition to your regimen

    MRI has always been the best NO2

    Posted by Willie on 7th Jun 2024

    MRI is tried and true. I’ve tried other NO2 products after MRI wasn’t available and there’s no comparison to MRI. Once they came back to market I notice the efficacy right away. People always comment on my vein popping guns with your product and it lowers my blood pressure naturally!

    Extremely glad these we're brought back into production. The first bottle I got was kind of chalky but I have had 3 bottles since that and they seem fine with a yellow coat to to them. The pump I get during my workouts and just overall fullness is forever unmatched. Thanks MRI

    Sustained energy!

    Posted by Jose Salgado on 31st Jan 2024

    I have been taking MRI NO2 for two weeks now and the energy I get afterwards was just amazing. Unlike pre-workout drinks, the energy I get was sustained and no crash at all. I do not drink pre-workout supplements anymore. Just a dose in the morning before breakfast and another in the afternoon before lunch w energize me the whole day. This NO2 from MRI is a game changer for me.
