ENANTIOMERICALLY PURE R-BETA-HYDROXYBUTYRATE MIXED SALT-ACID COMPOSITIONS

摘要

A ketogenic R-beta-hydroxybutyrate mixed salt-acid composition includes enantiomerically pure R-beta-hydroxybutyric acid and one or more enantiomerically pure R-beta-hydroxybutyrate salts. The R-beta-hydroxybutyric acid is more rapidly absorbed and utilized by the body than salts or esters, enhances taste, and reduces the need to include citric acid or other edible acids. The enantiomerically pure R-beta-hydroxybutyrate salt(s) are more slowly absorbed and utilized by the body and can provide one or more electrolytes. Compositions for increasing ketone body level in a subject may contain a dietetically or pharmaceutically acceptable carrier and an R-beta-hydroxybutyrate mixed salt-acid composition. The composition contains less than 100% by molar equivalents of total enantiomerically pure R-beta-hydroxybutyrate salts and more than 0% by molar equivalents of enantiomerically pure R-beta-hydroxybutyric acid.
