However, concurrent butyrate supplementation in the form of sodium, calcium, or potassium butyrate (or its esters) will prompt the body to induce endogenous ketone synthesis; serve as a ligand to stimulate receptors that the ketone or ketone body will also act on; contribute to the improvement of insulin and general metabolic health; support inflammatory and general immune system health; support neurological health; support gastrointestinal health and integrity; and serve as an energy substrate for ATP generation directly--all in parallel with the benefits that concurrent supplementation of the sister ketone body (BHB) will provide.
