How It Works
How It Works
L-Arginine is a conditionally essential amino acid that your body uses for protein synthesis and urea metabolism. During periods of stress, illness, or intense training, your body's demand for L-Arginine can exceed what it naturally produces. Free-form L-Arginine bypasses digestion for direct absorption.
Who It's For
Athletes and active individuals looking to support their protein needs. Adults following intense training programs or experiencing increased physical demands. Those wanting to supplement their amino acid intake between meals.
Who It's Not For
Not suitable for individuals with glaucoma, herpes simplex, or heart conditions unless prescribed by a physician. Avoid if you've had a heart attack or have coronary artery disease.
About This Product
What It Does
L-Arginine supports your body's protein synthesis and helps maintain healthy nitrogen balance. This conditionally essential amino acid becomes critical during periods of physical stress when your natural production can't keep up with demand.
Why It Works
- FREE-FORM ADVANTAGE: Unlike protein-bound arginine, free-form L-Arginine absorbs directly without requiring digestion.
- DOUBLE STRENGTH: Each serving delivers 1,000mg of L-Arginine — twice what you get from basic 500mg formulas.
- CONDITIONALLY ESSENTIAL: Your body produces L-Arginine naturally, but production drops during stress, making supplementation beneficial.
