Product education

L-Arginine 700mg by Douglas Laboratories

L-Arginine capsules, provided by Douglas Laboratories, contain 700 mg pure, crystalline L-arginine. Amino acids have many functions in the body, serving as the building blocks for all body proteins, including structural proteins that build muscle and functional proteins in the form of enzymes. L-arginine is a conditionally essential amino acid, particularly important during physical stress, trauma, or illness when the body’s production may be insufficient. It plays a crucial role in tissue protein synthesis, ammonia detoxification, and energy production.

Key Benefits

  • Supports muscle growth and recovery*
  • Enhances energy production*
  • Stimulates hormone release

How It Works / Key Ingredients

L-arginine is involved in the synthesis of creatine phosphate, which provides readily available energy for muscle contraction. It also acts as a precursor for polyamines that regulate cell growth and stability.

How to Use

As a dietary supplement, adults take 1-6 capsules daily or as directed by your healthcare professional.
