How It Works
How It Works
L-Proline is a conditionally essential amino acid that serves as a key building block for collagen synthesis. Your body uses proline to create and maintain the structural proteins found in skin, joints, tendons, ligaments, and blood vessels. While your body can produce some proline, dietary intake becomes important during periods of growth, healing, or when following plant-based diets.
Who It's For
Adults looking to support healthy aging of joints and connective tissue. Vegetarians and vegans who may have lower proline intake from diet alone. Active individuals who want to maintain structural health as they age.
Who It's Not For
Those with kidney disease should consult their healthcare provider before using amino acid supplements. Not recommended for children unless directed by a healthcare professional.
About This Product
What It Does
L-Proline supports your body's natural collagen production — the structural foundation that keeps your joints, skin, and connective tissues strong. This conditionally essential amino acid becomes particularly important as you age, when natural collagen synthesis begins to decline. Unlike many collagen supplements that provide already-formed proteins, proline gives your body the raw materials to build collagen exactly where it's needed.
Why It Works
- COLLAGEN SYNTHESIS: Provides the specific amino acid building blocks required for your body's natural collagen production process.
- STRUCTURAL SUPPORT: Helps maintain the protein matrix that forms the foundation of joints, tendons, ligaments, and blood vessels.
- BIOAVAILABLE FORM: Free-form L-Proline is readily absorbed and utilized by your body, unlike proline bound in food proteins.
What's Inside
Each 2-capsule serving delivers 1,000mg of pure L-Proline in vegetarian capsules. Contains no sugar, salt, wheat, gluten, corn, soy, milk, egg, shellfish or preservatives. NPN N/A.
Why we carry it: NOW's L-Proline delivers the full gram dose backed by collagen research — not the underdosed amounts found in many joint formulas.
