Arginine is a conditional amino acid, which means it can be manufactured by the body. However, in times of illness and stress, more may be needed than the body can produce. Arginine is found in foods such as dairy, meat, and fish. As a dietary supplement, "free form" L-arginine is easier for the body to utilise, as free form amino acids are already singular molecules that don't require digestion.

Arginine supports healthy heart function, strengthens the immune system, improves healing, and enhances the power, strength, intensity, and recovery of muscles. It also increases the production of nitric oxide, a substance that dilates blood vessels and aids in circulation. As a result, arginine may help with conditions that improve when blood vessels are relaxed.

Arginine stimulates protein synthesis and increases the force and power of skeletal muscle, which helps athletes and bodybuilders increase strength, optimise lean body mass, increase performance, and promote recovery. High intensity training weakens the immune system and can cause inflammation and injury. Arginine counteracts these effects by enhancing immune function, decreasing inflammation, and improving wound healing. It's especially important for athletes who train intensively, as they require extra support during training and a shorter recovery period.

  • Improves circulation by improving blood flow.
  • Supports performance and immune system of athletes and bodybuilders.
  • For use by those with stable a cardiovascular system.
  • Convenient 1000mg tablets for easier dosing.

How it works

Arginine is an amino acid that is involved in protein production, wound healing, and the production of nitric oxide and other important compounds. Nitric oxide is a molecule that is involved in many physiological processes, especially in the cardiovascular system. Many diseases are associated with low production of nitric oxide including diabetes, heart disease, high cholesterol, high blood pressure, obesity, and aging. Nitric oxide dilates blood vessels, increases blood flow, improves functioning of the endothelium, and inhibits platelet aggregation and smooth muscle proliferation. These effects help maintain normal cardiovascular function and blood pressure, and protect against oxidative damage.

In skeletal muscle, arginine causes the release of nitric oxide, prostaglandins, and other powerful compounds that increase muscle force and power, stimulate protein synthesis, maintain glucose homeostasis, and increase blood flow to muscles.

Arginine stimulates the release of hormones from the pituitary and adrenal glands, including growth hormone, insulin, and glucagon, which may help bodybuilders increase muscle strength and lean body mass. Arginine promotes protein synthesis, improves collagen deposition, improves wound strength, decreases inflammation, and strengthens the immune system, making it an important supplement for wound healing.
