What is it?
Proline is a unique amino acid that plays a crucial role in the formation of proteins, particularly collagen, which is vital for the structure and vitality of connective tissues. Unlike most amino acids, proline is not linear but rather has a cyclic structure, which contributes to the stability and function of proteins. It is known for its role in promoting skin elasticity and hydration.
Where does it come from?
Proline can be synthesized naturally by the human body, making it a non-essential amino acid. It is also found abundantly in dietary sources such as meat, dairy products, and certain vegetables like cabbage and asparagus. Proline can be produced via fermentation processes.
