Evaluating Your Fasting Objectives

The confusion often stems from the fact that it depends on your reason for fasting. If you are practicing intermittent fasting (IF) for weight management and caloric restriction, a small serving of collagen is unlikely to hinder your progress. Many users find that collagen is low in calories, so it is often allowed during fasting plans that are less rigid than a water-only fast.

However, if you are fasting to maximize autophagy—the body’s process of cleaning out damaged cells—the intake of amino acids may interrupt this process. In this specific scenario, taking collagen peptides during your fasting period would interrupt the fast.

My Personal Takeaway

While ten grams of collagen will technically break a strict caloric fast, the impact is often negligible compared to the potential benefits of the supplement itself. Hydrolyzed collagen (collagen peptides) has become a staple in my routine, but I treat it as a "break-fast" item rather than something I consume during deep fasting hours.
