Proline Effect on Probiotics Viability


Proline Probiotics are Alive!

What is Proline?

Proline is an essential component of collagen and is produced by various plants as a defensive material to survive in extreme environments. Youguth’s probiotics is combined with Proline for a protective coating that helps them survive harsh conditions in our gut.

CKD BiO Silk Fibroin Probiotics™

To further protect the probiotics in the acidic conditions of the gut, silk fibroin in diluted solutions is used to encapsulate these probiotics. The protective layer then melts away safely when the probiotics are ready to take effect, contributing greatly to its’ efficacy.

What is Silk Fibroin?

Silk Fibroin, an FDA-approved natural protein, is isolated from Bombyx mori silkworm cocoons and has hydrophobic characteristics. It is used in drug delivery applications because of their excellent biocompatibility, biodegradability and low immunogenicity.
