We generally advise against combining caffeine and collagen or consuming them within a few hours of each other. This recommendation is based on research indicating that caffeine can suppress collagen production by inhibiting cell growth and interfering with cartilage development. Consequently, this may impact the body’s ability to generate new collagen and regulate the genes involved in cartilage cell maturation.
That said, whether or not you consume caffeine, supplementing with collagen remains highly beneficial. We recommend taking collagen prior to workouts for optimal results. If eliminating caffeine in the mornings or pre-workout is not feasible, consider waiting a few hours after consuming caffeine before taking collagen or incorporating it into your bedtime routine instead.
