Description
Functions in the Body
Arginine is a conditionally essential amino acid that plays a vital role in several physiological processes, primarily through its ability to produce nitric oxide (NO), a key compound for cardiovascular health. By promoting the dilation and relaxation of blood vessels, arginine improves blood circulation and helps regulate blood pressure, contributing to overall heart health. In addition to its cardiovascular benefits, arginine aids in protein synthesis, supports immune function, and accelerates wound healing. This amino acid is particularly important for athletes, as it enhances physical performance and recovery by increasing blood flow and oxygen delivery to muscles. It also plays a role in hormone production, including growth hormones, which are essential for tissue repair and muscle growth. Regular intake of arginine can support cardiovascular wellness, improve athletic endurance, and boost immune response, making it a valuable addition to a balanced diet.
Deficiency Symptoms
A deficiency in arginine can lead to symptoms such as stiffness in the legs, slower growth, hair loss, skin rash, delayed development, intellectual disability, slow wound healing, and constipation.
Synergy & Antagonism
Arginine works synergistically with citrulline and nitric oxide boosters to improve blood flow. It may antagonize lysine due to competition in the body.
ARGININE
Warnings
Overdosing on arginine may cause abdominal pain, bloating, diarrhea, and exacerbate conditions like gout. In people with asthma, it may cause breathing problems. It can also interact with medications for high blood pressure, erectile dysfunction, and heart conditions, so caution is advised.
Food Sources
Rich sources of arginine include nutritional yeast, nuts, seeds, meat, legumes, seaweed, lentils, oats, corn, and chocolate.
Time Frame
Arginine can be taken at any time of day, with no specific timing required for its benefits.
Depleted By
Arginine levels can be depleted by a poor diet and excessive intake of lysine, which competes with arginine for absorption.
