Benefits

• Enhanced Nitric Oxide & Blood Flow: L-Arginine is a key precursor to nitric oxide — a molecule that helps relax and widen blood vessels, improving circulation, oxygen delivery, and nutrient transport to muscles. This can lead to better pumps, endurance, and performance during workouts.
• Improved Muscle Growth & Recovery: By supporting protein synthesis and nutrient uptake, Arginine may help with muscle repair and lean mass development post-exercise.
• Cardiovascular & Systemic Support: Enhanced circulation supports heart health, healthy blood vessel function, and overall vascular performance — beneficial both in and out of training.
• Hormone & Growth Factor Support: Arginine has been shown to stimulate natural growth hormone release, which can contribute to lean muscle growth and fat metabolism when combined with resistance training.
• Immune & Metabolic Roles: Involved in ammonia detoxification and immune function, supplemental L-Arginine also supports broader metabolic and health pathways.

Key Ingredient

• L-Arginine (Free-Form Amino Acid)

A semi-essential amino acid that:

• Acts as a nitric oxide precursor to support vasodilation and circulation.

• Supports protein synthesis and nutrient transport to muscle cells.

• May promote growth hormone release and assist with metabolic and immune functions.

NutraBio’s formula is pure L-Arginine without additives, ensuring a clean, focused dose of this amino acid.
