Abstract: Beta-hydroxybutyrate compositions for administering ketone bodies to a subject include a non-racemic mixture of R-beta-hydroxybutyrate and S-beta-hydroxybutyrate enriched with R-beta-hydroxybutyrate so as to contain more than 50% and less than 100% by enantiomeric equivalents of R-beta-hydroxybutyrate and less than 50% and more than 0% by enantiomeric equivalents of S-beta-hydroxybutyrate. Non-racemic mixtures of beta-hydroxybutyrate include one or more R-beta-hydroxybutyrate salts, one or more S-beta-hydroxybutyrate salts, one or more R-beta-hydroxybutyrate esters, one or more S-beta-hydroxybutyrate esters, R-beta-hydroxybutyric acid, S-beta-hydroxybutyric acid, and combinations thereof.

Abstract: 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.

Abstract: Beta-hydroxybutyrate compositions formulated for ingestion by oral delivery as a beverage, or as a dietary supplement for addition to water or beverage, include a liquid carrier, such as water, milk, drinkable liquid, coconut water, watermelon water, or electrolyte water, and beta-hydroxybutyrate. The beta-hydroxybutyrate composition can include enantiomerically pure R-beta-hydroxybutyrate or a non-racemic mixture enriched in R-beta-hydroxybutyrate relative to S-beta-hydroxybutyrate. Alternatively, the beta-hydroxybutyrate composition can include enantiomerically pure S-beta-hydroxybutyrate or a non-racemic mixture enriched in S-beta-hydroxybutyrate relative to R-beta-hydroxybutyrate. Alternatively, the beta-hydroxybutyrate composition can include a racemic mixture of R-beta-hydroxybutyrate and R-beta-hydroxybutyrate. The beta-hydroxybutyrate compositions comprise beta-hydroxybutyric acid and optionally one or more beta-hydroxybutyrate salts or esters.

Abstract: Compositions for improving metabolic function in a subject include optically pure S-beta-hydroxybutyrate or non-racemic mixtures enriched with the S-enantiomer. S-beta-hydroxybutyrate in pure or enriched form provides energy to the heart, dilates the arteries, decreases blood pressure and systemic vascular resistance, and increases cardiac output. S-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. S-Beta-hydroxybutyrate salts are more slowly absorbed and utilized by the body and provide one or more electrolytes. S-Beta-hydroxybutyrate esters provide more controlled release without adding electrolytes. Compositions for improving heart function in a subject may contain a dietetically or pharmaceutically acceptable carrier and optically pure S-beta-hydroxybutyrate or non-racemic mixture enriched with S-beta-hydroxybutyrate, wherein the compositions contain from about 50.

The compositions may optionally include one or more ketone body esters, such as one or more beta-hydroxybutyrate esters and/or one or more acetoacetate esters. An example composition contains about 2% to about 98% on a molar basis of the one or more beta-hydroxybutyrate salts and the one or more acetoacetate salts, about 2% to about 98% on a molar basis of the beta-hydroxybutyrate free acid and optionally the acetoacetate free acid, and optionally about 2% to about 98% on a molar basis of one or more ketone body esters.

Abstract: Compositions for inducing and maintaining a state of flow in a subject include optically pure S-beta-hydroxybutyrate or non-racemic mixtures enriched with the S-enantiomer. The S-beta-hydroxybutyrate enantiomer modulates the effect of ketone bodies in the subject and controls the rate at which ketosis is achieved. 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. Beta-hydroxybutyrate salts are more slowly absorbed and utilized by the body and can provide one or more electrolytes.

Abstract: Compositions for improving heart function in a subject include optically pure S-beta-hydroxybutyrate or non-racemic mixtures enriched with the S-enantiomer. S-beta-hydroxybutyrate in pure or enriched form provides energy to the heart, provides antiglycation and signaling, which lessens or reduces cardiovascular disease by lessening or preventing atherosclerosis, plaque formation, diastolic dysfunction, systolic dysfunction, fibrosis, and hypertension, and/or by facilitating normal nitric oxide (NO) production, which dilates the arteries, reduces blood pressure and systemic vascular resistance, and increases cardiac output in humans. S-Beta-hydroxybutyric acid is more rapidly absorbed and utilized by the body than salts or esters. S-Beta-hydroxybutyrate salts are more slowly absorbed and utilized by the body and provide one or more electrolytes. S-Beta-hydroxybutyrate esters provide more controlled release without adding electrolytes.

Abstract: An autobiotic composition includes a prebiotic component and postbiotic component. The prebiotic component is a substance resistant to digestion in the stomach and small intestine and selectively fermentable by microorganisms in the large intestine. The postbiotic component is a short-chain fatty acid, such as butyric acid, lactic acid, succinic acid, or salt or ester thereof, such as tributyrin. An autobiotic composition beneficially combines the microbiome-enhancing effects of a prebiotic with the intestinal healing effects of a postbiotic to provide overall benefits to digestive health. A seedbiotic component may form part of or be co-administered with the autobiotic composition. Enzymes may form part of or be co-administered with the autobiotic composition to enhance digestion of the prebiotic in the stomach and intestine and/or increase microbiome health. An exogenous ketone body component may form part of or be co-administered with the autobiotic composition.
