A killer workout starts with Bio-Synergy L-Arginine. With 1000mg L-arginine in each capsule, our nitric oxide boosting formula increases the volume of blood flowing to your hard-working muscles, which also increases the level of oxygen and nutrient delivery, so your muscles can work harder. In short, you’ll have more stamina and power than you normally do.

L-Arginine is perfect for sports that require explosive actions, such as weight training, sprinting, boxing or crossfit. But it’s also popular with endurance athletes who want to push their stamina. That’s why you’ll find L-arginine in just about every pre workout supplement out there.

It also helps with muscle growth because the body uses this amino acid in the synthesis of most proteins. When the size of a muscle increases, L-arginine helps to boost the release of growth hormone, which then aids in fat metabolism.

L-arginine, the only ingredient in Bio-Synergy Arginine, is an ideal pre workout supplement that can help you have an explosive workout. L-arginine is proven to boost short-term nitric oxide (NO) levels, which increases the volume of blood flowing through to your muscles. This leads to more oxygen, amino acids and glucose being delivered to the muscles that need them most. This results in more power and stamina.

While L-arginine is popular with gym goers, it’s also ideal for any athlete that wants to improve muscle recovery. The enhanced blood circulation means that more restorative nutrients can be delivered to distressed muscles, helping to speed up their recovery.
