🧪 Formulation Notes

We have added a proprietary blend of three effective substrates of arginine for maximum pharmacokinetics, including Arginine Alpha-Ketoglutarate (A-AKG), Arginine Ketoisokaproate (A-KIC), and Arginine HCl.

Additional Information

Max Nitro 2 is a masterfully formulated pre-workout innovation to promote the body’s production of nitric oxide. This scientifically-based formula is designed to provide insane muscle pumps, intensity and performance. Max Nitro 2 provides two levels of support two levels of support for NO production, the amount of arginine substrate needed for nitric oxide production and amplification of the endothelial nitric oxide (eNOS) enzyme that facilitates the conversion of arginine to nitric oxide.

L-Citrulline plays a pivotal role in supplying arginine to eNOS and has the unique ability to recycle itself to maximize and sustain NO levels. Quercetin enhances nitric oxide bioactivity for extended NO kinetics. Exciting new research has shown that Resveratrol upregulates eNOS mRNA expression resulting in enhanced NO production. Vitamin C has been known to have beneficial vascular effects by increasing the bioavailability of NO and may prevent endothelial dysfunction by scavenging free radicals. Other science-supported cofactors promoting eNOS activity include Thiamin, Niacin and Vitamin B6. Magnesium is a component of hundreds of enzymes and potentiates nitric oxide production and energy support.
