Trial Summary

What is the purpose of this trial?

This trial studies how different ages and overall health affect the body's response to a special drink. Participants will consume the drink, and researchers will measure how their bodies process it by checking blood and urine levels.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but it requires that you maintain your medication habits throughout the study. If your medication use is unstable and might affect the trial outcomes, you may be excluded from participating.

What data supports the effectiveness of the treatment Ketone Supplements for Ketosis?

Research shows that ketone supplements, like the ones used in the trial, can safely increase blood ketone levels, which is a state known as ketosis. This state has been associated with potential benefits for physical and cognitive performance, making ketone supplements a practical way to achieve ketosis without dietary changes.12345

Is it safe for humans to consume ketone supplements?

Research shows that ketone supplements, like ketone esters and monoesters, are generally safe and well-tolerated in healthy adults. Some mild gastrointestinal effects, like nausea, may occur, especially at higher doses, but no significant changes in vital signs or lab tests were observed.13456

How is the ketone supplement treatment different from other treatments for ketosis?

The ketone supplement, specifically bis hexanoyl (R)-1,3-butanediol, is unique because it induces ketosis without requiring dietary changes, unlike traditional methods that rely on high-fat, low-carbohydrate diets. It is available in novel forms like powder and ready-to-drink beverages, which rapidly increase blood ketone levels, making it a convenient option for achieving nutritional ketosis.34578

Findings from Research

Exogenous ketone drinks, such as ketone esters and ketone salts, effectively raise blood D-β-hydroxybutyrate (D-βHB) levels, with significant increases observed in a study of 15 participants, indicating a practical alternative to traditional ketogenic diets.
Both types of ketone drinks lowered blood glucose and triglyceride levels without causing adverse effects on blood electrolytes, suggesting they are safe and beneficial for metabolic health.

Both powdered and ready-to-drink (RTD) formulations of the novel ketone ester BH-BD effectively induce ketosis in healthy adults, increasing blood beta-hydroxybutyrate (BHB) levels within approximately 15 minutes after consumption.
The study found that a higher dose of the powdered formulation (25g) resulted in significantly greater BHB concentrations compared to lower doses and the RTD version, but both formulations were equally effective in raising BHB levels without affecting blood glucose concentrations.

A novel ketone di-ester, bis hexanoyl (R)-1,3-butanediol (BH-BD), effectively raises blood levels of beta-hydroxybutyrate (BHB) to 0.8-1.7 mM in healthy adults, indicating successful induction of ketosis without dietary changes.
The study showed that higher doses of BH-BD (25g) resulted in greater increases in BHB levels compared to lower doses (12.5g), while also decreasing plasma glucose and free fatty acids, suggesting potential metabolic benefits.
