A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study investigates how individual characteristics, such as age and metabolic health, influence the metabolism of ketones. It aims to recruit a diverse group of participants aged 20 to 70, representing various metabolic health statuses, to assess their response to ketone supplementation. The research will involve blood and urine analysis, as well as questionnaires to evaluate tolerability and satiety. The ultimate goal is to develop guidelines for the effective use of ketone supplements tailored to individual needs.

Inclusion Criteria:

* Ages 20 - 70 years
* Participant is willing and able to comply with all study procedures including the following prior to Test Day: fasting (\>10 h; water only), no alcohol (\>24 h), no exercise (\>24 h), no acute illness and controlled feeding before the Test Day, maintain diet, exercise, medication, and supplement habits throughout the study.
* Participant has no health conditions that would prevent completion of the study requirements as judged by the Investigator based on health history.
* Participant understands the study procedures and signs forms providing informed consent to participate in the study and authorizes the release of relevant protected health information to the Investigator.

Exclusion Criteria:

* Participant follows a low-carbohydrate diet (\<30% energy from carbohydrate) or have used exogenous ketone supplements within 4-months of study participation.
* Participant has a Primary Care Physician diagnosed history or presence of uncontrolled and/or clinically important hypertension (blood pressure \>150/95 mmHg), pulmonary, cardiac, hepatic, renal, endocrine (including type 1 and 2 diabetes), hematologic, immunologic, neurologic (e.g., Alzheimer's or Parkinson's diseases), psychiatric (including unstable depression and/or anxiety disorders) or biliary disorders.
* Participant has a known allergy, intolerance, or sensitivity to any of the ingredients in the study beverages, including soy and milk protein, wheat, shellfish, fin fish, eggs, tree nuts or peanuts (production facility handles nuts).
* Participant has unstable use of a medication or supplement that the Investigator considers may affect the outcomes of the trial.
* Consumption of alcohol more than 3 drinks per day or more than 18 drinks per week.
* Consumption of tobacco.
* Consumption of cannabis.
* Participant is currently in another research study or has been in the 14 days before screening.
* Participant has had a blood draw or donation in the last 8 weeks.
* Participant has a clinically important gastrointestinal (GI) condition that would potentially interfere with the evaluation of the study beverage \[e.g., inflammatory bowel disease, irritable bowel syndrome, chronic constipation, severe constipation (in the opinion of the Investigator), history of frequent diarrhea, history of surgery for weight loss, gastroparesis, systemic disease that might affect gut motility according to the Investigator, medication managed reflux and/or clinically important lactose intolerance\].
* Participant has a condition the Investigator believes would interfere with his ability to provide informed consent, comply with the study protocol, which might confound the interpretation of the study results, or put the participant at undue risk.
