L-Proline is one of the twenty amino acids that help in building blocks of proteins. It is the only DNA-encoded amino acid that has a secondary amino group alpha next to the carboxyl group. It plays a crucial role in the proper functioning of joints and tendons. Also, an essential component of collagen maintains and strengthens heart muscles.

L-proline is good for skin health, joint and bone support, muscle recovery, digestive health and cardiovascular health.
L-Proline is hydrophobic in nature due to the presence of an aliphatic chain and pyrrolidine ring.
L-Proline is the same as Proline. L-Proline is a specific stereoisomer of proline. It is one of the 20 amino acids.
L-Proline is naturally present in the body, hence making it a non-essential amino acid and it is also present in certain food items. Â
L-Proline indirectly helps in the hair growth by aiding the collagen formation which anchors the hair follicles and strands.
