★★★★★ "I won't go back to high street supplements. The difference in quality is something you can actually feel." Susie
L-proline is an amino acid the body makes and gets from food. With glycine it makes up most of collagen, the protein of skin, tendons and cartilage.
Proline is used wherever collagen is built or repaired. People take it with glycine and vitamin C when they want the building blocks of collagen from a vegan source.
Each capsule provides L-proline with nothing else apart from the vegetable shell. It is often chosen alongside the Glycine capsules and Vitamin C powder.

Frequently asked questions
What is Proline good for?
Proline provides amino acids that serve as building blocks for proteins.
When should I take amino acids?
Often best on an empty stomach for optimal absorption.
Can I take this with protein?
Yes, though taking separately may improve absorption.
What are amino acids used for in the body?
Amino acids build proteins, neurotransmitters, hormones, and enzymes. Each has specific functions beyond protein synthesis.
Are amino acid supplements safe?
Generally yes for most people. Those with certain metabolic conditions should consult a practitioner.
Do you ship internationally?
Yes. We ship worldwide from the UK. Duties, taxes and delivery costs for your country are calculated and shown at checkout.
Why capsules rather than tablets?
Tablets need binders, fillers and a coating to hold their shape. A capsule is a cellulose shell around the powder, so it carries no binders and breaks down quickly once swallowed.
