Stamina Takes a Big Leap



The POWERHOUSE of nitrate delivery!

Oxystorm® is an extract of Amaranthus one of the highest dietary sources of nitrates discovered. Nitrates improve energy conversion in human cells and thus reduce fatigue during exercise. Dietary nitrate is an alternative source of nitric oxide(NO) when normal pathway is dysfunctional. Nitrate is secreted from salivary glands to mouth, which in presence of oral bacteria gets converted to nitrites which gets absorbed into systemic circulation and this nitrite is responsible for NO produced as and when required. Nitric Oxide is essential for normal functioning of vital organs.

At Arjuna Natural Extracts Ltd., our unique extraction process has resulted in the world’s first nitrate enriched extract from Amaranthus. Oxystorm®(Patent pending) provides four times the amount of nitrate as compared to conventional sources like beet root. This 100% water soluble extract has neutral pH of 7, is oxalate free and available in a convenient powder form.


Key Benefits

Enhances Nitric Oxide levels in the body

Nitric Oxide functions as a vasodilator and causes relaxation of smooth muscles.

Improves Ventilatory threshold

Improves lactate threshold

Significantly reduces the fatigue level and delays exhaustion


Oxystorm® can either be dissolved in water or used as a key ingredient in energy drink, energy bar, candy chewing gum, capsule, tablet and more

Clinical Science

Oxystorm® : Nitrate surge for an INSTANT Nitric Oxide Boost!

Universal energy currency of the living world is mainly synthesized by the mitochondria of the cell , the power house, that occupy 20% of the cell volume which utilizes oxygen . The energy produced is exported to all parts of the body to provide energy for the cellular work. Economy of energy conversion is very crucial during vigorous exercises or else it may lead to oxygen debt. In a recent study (Subramanian et al.,2016)it was observed that Oxystorm can deliver high nitrate and enhance nitric oxide levels in the body (Graph 1). Our clinical studies have shown that Oxystorm® enhances the nitric oxide by converting nitrate to nitrite. Nitric oxide generated from Oxystorm® enhances VO2 and maximize the energy produced and thus reduces extreme fatigue and physical weakness during strenuous exercise or physical activity.

Nitric oxide has been identified as an important endothelium derived relaxing factor, which is released from the endothelium and results in vascular smooth muscle relaxation (Palmer et al., 1987). The authors have also reported that the increased level of nitric oxide is due to the high level of nitrite in saliva (Graph 2)
