Description
Doctor’s Best Fast Acting Arginine Complex with Nitrosigine features a patented form of inositol-stabilised arginine silicate (Nitrosigine) that has been shown in clinical research to be significantly more effective at raising and maintaining blood arginine levels than standard L-arginine. Greater arginine availability means more robust and sustained nitric oxide production.
Nitric oxide promotes vasodilation – the widening of blood vessels – which improves blood flow, nutrient delivery to muscles, cardiovascular efficiency and the muscle pump during training. Nitrosigine’s superior bioavailability makes each dose work harder and last longer.
Key Benefits:
- Nitrosigine – clinically superior arginine form
- Greater and more sustained nitric oxide production
- Supports muscle pump, blood flow and performance
- Cardiovascular health benefits
- From Doctor’s Best – science-based US supplements
Take 2 tablets 30″“60 minutes before exercise for performance support, or daily for cardiovascular benefits.
