Collagen is not only the most abundant protein in the human body, but it is the most abundant protein in the ENTIRE animal kingdom. Meaning that it is the most abundant protein across all animals.
Collagen is extremely involved in making tendons, ligaments, hair, skin, and nails.
zuCollagen and zuBroth are extremely dense in the amino acids glycine, proline, and alanine. These amino acids are the raw material that your body needs in order to build the necessary components for optimal joint health.
Supplementing with even more glycine prior to sleep with zuSleep is going to maximize these processes.
