  • Patent number: 11806328
    Abstract: Ketone supplementation, such as through use of precursors of beta-hydroxybutyrate (BHB) and acetoacetate (AcAc), increased blood levels of ketone bodies, increases blood flow and wound closure in ischemic young and aged fisher rats significantly earlier compared to standard diet in aged rats. In vitro experiments with ketone bodies demonstrate decreased mitochondrial and cytosolic ROS in young and aged primary human dermal fibroblasts (PHDF). Ketone bodies increased migration in young and aged PHDFs.

  • Publication number: 20210100766
    Abstract: The ketogenic diet (KD) has therapeutic implications in many disease states. It was hypothesized ketone precursor supplementation would elevate blood ketone levels to therapeutic ranges (2-7 mM) without need for dietary restriction. The effects of ketogenic agents were tested on blood glucose, ketones, and lipids with a 28-day dose escalation study in male Sprague-Dawley rats: R,S-1,3-Butandiol (BD), acetoacetate ketone ester (KE), and control (H2O) (n?8). Days 1-28, rats received a daily 5g/kg intragastric gavage, based on previous toxicology studies. Once weekly, whole blood samples (10 ?l) were acquired for analysis of glucose and ?HB at 0, 0.5, 1, 4, 8, and 12 hours after test substance administration, or until ?HB returned to baseline. At day 1 and 28, 10 ?L of whole blood were collected to measure triglycerides, total cholesterol, and HDL concentration. Significant elevation of blood ketone was observed with a significant inverse relationship with blood glucose for the duration of the experiment.

  • Publication number: 20200268701
    Abstract: Beta-hydroxybutyrate mineral salts in combination with medium chain fatty acids or an ester thereof such as medium chain triglycerides were used to induce ketosis, achieving blood ketone levels of (2-7 mmol/L), with or without dietary restriction. The combination results in substantial improvements in metabolic biomarkers related to insulin resistance, diabetes, weight loss, and physical performance in a short period of time. Further, use of these supplements to achieve ketosis yields a significant elevation of blood ketones and reduction of blood glucose levels. Use of these substances does not adversely affect lipid profiles. By initiating rapid ketosis and accelerating the rate of ketoadaptation, this invention is useful for the avoidance of glucose withdrawal symptoms commonly experienced by individuals initiating a ketogenic diet, and minimizes the loss of lean body mass during dietary restriction.
