Arginine is an amino acid used as a supplement to support blood vessel and metabolic health.
It is commonly used for:
• Circulatory support: Used to help support healthy blood flow and blood vessel function.
• Wound healing support: Used to support the body's natural healing processes.
• Exercise performance: Used by some as a supplement to support exercise performance and recovery.
• Certain metabolic conditions: Used under medical guidance to help manage specific inherited metabolic disorders.
Nausea
Abdominal pain
Rash and swelling
Low blood pressure
Worsening of asthma symptoms
Arginine works mainly by helping the body produce nitric oxide, a molecule that helps blood vessels relax and widen.
This can support healthy blood flow and circulation throughout the body.
Arginine is also involved in protein synthesis and wound healing, as it plays a role in producing other compounds needed for tissue repair and immune function.
