Overview
Oxystorm is a standardised red spinach extract delivering ~9% naturally occurring nitrate (~90 mg per 1 g), a low-volume alternative to beetroot for the nitrate→nitrite→NO pathway.
Mechanism & Function
Mechanism of Action
Increases plasma nitrite and NO, improving mitochondrial efficiency, oxygen cost of exercise, and pump.
Physiological Role
Lower-volume nitrate source vs beetroot juice; useful for endurance athletes and pump stacks at 1–2 g doses.
Primary Pathways
Performance / Health Relevance
Manufacturer RCTs show improved time-to-exhaustion at ~1 g dose; consistent with broader nitrate literature.
