Navigating the nuances of intermittent fasting often leads to one persistent question: do collagen peptides break your fast? As someone who has incorporated these supplements into a daily wellness routine for years, I have spent considerable time observing how different additions to my morning regimen affect my progress.

Collagen peptides are a popular supplement for a reason. They contain specific amino acids like glycine and proline.
