Abstract: Protein-complexed MCT oil includes MCT droplets or particles encapsulated by and/or complexed with protein-based wall material. Protein-complexed MCT oil can be used as an additive for food products. The wall material includes protein, e.g., pea protein, emulsifier(s), optional co-emulsifier(s), and optional polysaccharide(s). Protein-complexed MCT oil may optionally include supplemental oil(s), such as that contain one or more essential omega-3 fatty acids (ALA, EPA and DHA) and optionally one or more essential omega-6 fatty acids. The protein-complexed MCT oil may be consumed by users as desired, e.g., by adding the protein-complexed MCT oil to food or drink products, such as plant flour (e.g., to make blended plant-MCT flour), liquid coffee creamer, bubble tea, jelly, ice cream, yogurt, processed meats (e.g., lunch meat), pet foods, baked foods, vitamin supplements, energy bars, and drink mixes. The food and drink products have increased nutrition provided by the MCT oil and pea protein.

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.

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.

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-hydroxybutyrate salts are more slowly absorbed and utilized by the body and can provide one or more electrolytes. Compositions for controlling ketone body level 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 50.5% to 100% by enantiomeric equivalents of S-beta-hydroxybutyrate and from about 49.

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.
