A new kind of Fasting with COLLAGEN

Collagen Fasting: Benefits, Risks, and How It Affects Intermittent Fasting

Collagen fasting refers to the practice of consuming collagen peptides, powders, or supplements while following intermittent fasting. Many people wonder if collagen breaks a fast and whether it still allows the body to reap the metabolic and longevity benefits of fasting. Unlike black coffee, tea, or water, collagen contains amino acids and small amounts of calories, meaning it technically breaks a strict fast. However, some use collagen during fasting windows to support skin elasticity, joint health, gut lining repair, and muscle recovery while still maintaining some of the weight loss and autophagy benefits of intermittent fasting.

Collagen peptides may enhance fasting by reducing hunger, preserving lean muscle mass, and promoting youthful skin, but they may interfere with deeper cellular repair processes that occur in a true fast. Understanding when to take collagen—whether during your eating window, before workouts, or alongside bone broth—can help you maximize both fasting benefits and collagen’s anti-aging effects.

If you’re exploring collagen fasting, consider your goals: fat loss, skin health, longevity, or autophagy. For strict fasting purists, collagen should be avoided until the eating window. For flexible fasting approaches, collagen may be a supportive supplement that boosts wellness without completely negating fasting benefits.
