An interventional study of high absorption CoQ10 product and standard CoQ10 product in CoQ10 Blood Levels, sponsored by Midwest Center for Metabolic and Cardiovascular Research. Completed at 1 site in United States. Open to participants aged 21 Years to 65 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-08-24.

The goal of this clinical trial is to compare the relative bioavailability of coenzyme Q10 (CoQ10) from acute administrations of a CoQ10 product designed for enhanced absorption versus a standard CoQ10 product in healthy men and women. Participants will be asked to come to the clinical on five different occasions, including a screening visit (visit 1, -7 days), two test 1 visits (visits 2 and 3, days 0 and 1), and two test 2 visits (visits 4 and 5, days 7 and 8). During the start of each test visit (visits 2 and 4), the participant will consume each study product with water and a standardized breakfast meal. Then, blood samples will be collected over a 10-hour period, and a standardized lunch, dinner, and snacks will be provided. The participant will return to the clinic the next morning for a blood draw 24 hours after the study product ingestion from the previous day. The same procedures will be repeated 7 to 14 days later with the other study product.
The study products will include 100 mg CoQ10 product designed for high absorption (administered as two 50 mg capsules) and 100 mg standard CoQ10 product (administered as two 50 mg capsules).

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
