Comparison of Pharmacokinetic Responses to Three Ketone Esters

Running, not enrolling · Not applicable

Conditions studied: Healthy Volunteer

In brief

The purpose of this study is to examine how the body absorbs, digests, and metabolizes three different investigational ketone dietary supplements (ketone monoester, ketone tri-ester, ketone salt) and to assess gastrointestinal tolerance or other adverse effects. This study is considered investigational because data are being collected on the differences over time between three active study products. Consumption of these study products are not intended to diagnose, treat, cure, or prevent any disease.

If the first measurement is slightly elevated above these limits, the subject will be given a brief (5 minute) rest period, and two more measurements will be taken. The average of all three measurements will be used to determine eligibility.

• Willing to duplicate and record their previous 24-hour diet, refrain from caffeine, alcohol and exercise for 24 hours prior to each visit, and fast for 10 hours prior to each visit.
• Subject agrees to maintain existing dietary and physical activity patterns throughout the study period.

• Individuals who are determined to have liver, renal, cardiovascular, neurological, or other metabolic disease.
• History or presence of diabetes, prediabetes or endocrine disorder.
• Use of any dietary supplements or medications which may confound the study or its endpoints (e.g., fish oil, choline donors, gingko biloba, phosphatidylserine, huperzine A, etc.).

• Chronic inflammatory condition (e.g., rheumatoid arthritis, Lupus, HIV/AIDS, etc.).
• Previous medical diagnosis of asthma, gout, or fibromyalgia.
• Currently following a low-carbohydrate, keto type diet, or practicing an intermittent fasting lifestyle (>14 hours of fasting).
• Subjects that have donated blood or plasma within the previous week.
• Pregnant women, women trying to become pregnant, women less than 120 days postpartum or nursing women. Women who participate in this study must agree to the use of contraception for the duration of the study and any woman that is sexually active will have to take pregnancy test prior to enrolling with a negative result.
