Arginine is a semi-essential amino acid, meaning your body can produce it, but dietary intake becomes important during growth, stress, or illness. Arginine is critical for:
- Protein synthesis and muscle growth
Wound healing and immune defense
Production of nitric oxide, a key molecule for healthy blood vessel dilation, blood pressure regulation, and brain signaling
Adequate arginine is closely linked to cardiovascular benefits and may support healthy blood flow, balanced blood pressure, and enhanced athletic or sexual performance.
Rich dietary sources of arginine include: meat, poultry, fish, dairy products, nuts, seeds, and legumes.
Arginine is also available as a dietary supplement to target specific needs.
Low arginine levels may compromise blood vessel health, slow healing, weaken immune response, and increase risks for metabolic or cardiovascular concerns.
