Are you feeling as if you’re not able to digest the foods you used to love, even indulge in? There’s a reason! The body’s primary digestant and disinfectant is Hydrochloric Acid (HCl). Hydrochloric Acid (HCl) is produced by the stomach and has the job of breaking down proteins. If you make plenty of HCl, then the body can adequately digest protein. If not, protein digestion is compromised. Low HCl signals the beginning of all digestive problems that plague modern man.
