Proline is a non-essential amino acid that is part of the protein composition. Even if the body knows how to synthesize proline, it is important to provide enough via the diet because it enters the collagen metabolism essential for the integrity of joints, tissues and tendons.
Characteristics of proline:
- Non-essential amino acid
- Amino acid with unique structure
- Allows to synthesize collagen
- A good supply of proline is important for the joints, the dander and the tendons
- Mostly found in foods of animal origin
Why consume proline-rich foods
Benefits
Proline is an amino acid synthesized by the body from glutamic acid.
Synthesis of collagen
Proline enters the collagen metabolism that is essential for the joints, skin and tendons.
Promoting healing
In case of injury, a sufficient amount of proline in the body will help a good healing.

How to use proline well
Use of proline
For the maintenance of good health, it is recommended to have a proline intake of 500 to 3000 mg per day.
As proline has a positive impact on the quality of connective tissue and healing, supplementation may be indicated to help heal and provide strength and strength to nails, skin and hair.
The dosage can vary from 500 to 4000 mg per day depending on the problem and the context.
Undesirable effects of proline
Consequence of proline deficiency
In case of proline deficiency, there is a fragility of the skin, joint problems and fragility of the blood vessels.
Consequences of an excess of proline
For a healthy adult, proline in large quantities does not induce health consequences.
Interactions with other elements
In general, a diet rich in vitamins and amino acids promotes the synthesis of proline and collagen.
Chemical Properties
The formula of this amino acid is C 5 H 9 NO 2, its molecular weight 115, 1305 g / mol. Proline has a unique structure; it is the only protein-forming amino acid to have a secondary amine.
The proline residues can regroup to form helices, which is what happens during the collagen synthesis.
