S-Beta-hydroxybutyric acid compositions for oral delivery are effective in rapidly raising blood ketone levels without causing acute acidosis or gastrointestinal (GI) distress when consumed in sufficiently dilute form and / or as a gel or suspension. By limiting added beta-hydroxybutyrate salts containing alkali or alkaline earth metal ions, beta-hydroxybutyric acid solutions, gels, or suspensions can deliver exogenous ketone bodies without significantly altering electrolyte balance. Although aqueous beta-hydroxybutyric acid solutions are moderately acidic with a pH of about 3.5 to 4, when diluted with sufficient water, the water acts as a pseudo buffering agent that offsets otherwise harsh acidic effects when consumed orally. Gels and suspensions can also ameliorate acidic effects by partially encapsulating the beta-hydroxybutyric acid. Beta-hydroxybutyric acid can be pure S-beta-hydroxybutyric acid or a non-racemic mixture enriched with S-beta-hydroxybutyric acid relative to R-beta-hydroxybutyric acid.
