What is L-proline good for?
L-proline is what is known as an amino acid, which means that it is used by the body as a building block for producing proteins. As the human body is capable of producing its own proline, it is not classified as an essential amino acid, however additional proline intake is important to ensure optimal protein production.
Role in collagen production
One of the most important proteins that L-proline is associated with is collagen, which serves as the framework for our skin, muscles, bones, tendons, cartilage, and other connective tissues, in addition to our organ membranes and artery walls. It is the most prevalent protein in the human body, and perhaps the most important.
For this reason, L-proline is often taken to promote skin health and enhance wound healing.
When should I take L-proline?
As with most amino acids, L-proline is best taken between meals, on an empty stomach, in order to maximize bioavailability and absorption.
What does L-proline combine well with?
L-proline with L-lysine and vitamin C, for cardiovascular health
L-proline features prominently in Linus Pauling's heart health protocol, alongside L-lysine and vitamin C.
The idea is that L-lysine is tasked with dissolving atherosclerotic plaques that adhere to any damaged artery walls, while L-proline compliments vitamin C in the production of collagen necessary for rebuilding and repairing these artery walls and ensuring that they remain smooth, and free of any lesions for future plaque to adhere to.
What are natural sources of L-proline?
If you are interested in achieving your daily L-proline intake through your diet, rich sources of L-proline include:
- Bone broth
- Beef liver
- Beef
- Chicken
- Salmon
- Eggs
- Cabbage
- Asparagus
- Peanuts
