Switch Arginine

Switch Nutrition’s 100% Pure L-Arginine is a clean, unflavoured amino-acid powder formulated to support blood flow, recovery, and performance. Each 1 g serve delivers a full gram of L-Arginine — a conditionally essential amino acid that helps the body produce nitric oxide, which can support healthy circulation and improve delivery of oxygen and nutrients to muscles. 

When used before workouts, it can help improve blood flow and nutrient delivery to working muscles, potentially enhancing endurance, performance and recovery. On non-training days, it remains a useful addition to support cardiovascular health, circulation and overall metabolic function. 

This formulation is simple and straightforward — just pure L-Arginine, with no fillers or flavours — making it easy to stack with other supplements or mix with water or a shake. 

Incorporate L-Arginine into your pre-workout supplement routine by taking about 30 minutes before exercise. This timing helps maximise the vasodilatory effects, enhancing blood flow when you need it most.

On non-training days, L-Arginine can still support health and recovery, so consider taking it with breakfast or lunch to maintain its benefits.

Not suitable for children under 15 years or pregnant women. Should only be used under medical or dietetic supervision. Not suitable as a sole source of nutrition and should be consumed in conjunction with a nutritious diet and appropriate exercise program.
