Natural Factors L-Arginine supports healthy heart function, circulation, immunity, and healing. As a free-form amino acid, it is more effective than when sourced from food. It promotes the secretion of growth hormone and boosts the body’s nitric oxide production to relax blood vessels and improve blood flow.
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 utilize, 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, optimize 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.
The amino acid L-arginine is used to make nitric oxide, a compound in the body that relaxes blood vessels. Studies have found that L-arginine may help with conditions that improve when blood vessels are relaxed. May help support a modest improvement in exercise capacity in individuals with stable cardiovascular disease (CVD). Supports healthy immunity.
