Others claim to be the most bioavailable butyrate. We proved it.

BIOMEnd® is a next-generation L-lysine butyrate. In a published clinical trial it was clinically shown to deliver 5× the peak blood butyrate and 1.75× the total butyrate exposure of tributyrin. Protected by multiple patents. Backed by a randomized clinical trial.

Randomized, single-blinded crossover clinical trial in 10 healthy men; each product dosed in 3 capsules standardized to deliver an equivalent amount of butyrate (La Monica et al., Journal of Exercise and Nutrition, 2025;8(1):4). Individual results may vary.
