Study Summary

This trial will study the effects of MitoQ, a mitochondria-targeted antioxidant, on vascular function in older adults.

Who is the study for?
This trial is for men and women aged 60 or older who are mentally fit (with a mini-mental exam score of at least 21), not alcohol dependent, have had stable weight recently, and aren't heavily involved in vigorous aerobic activities. Those with uncontrolled thyroid disease or recent blood donations are excluded.Check my eligibility
What is being tested?
The study tests if MitoQ, an antioxidant targeting mitochondria, can improve vascular function by reducing oxidative stress in the elderly when taken orally for three months compared to a placebo. The effects on endothelial function and aortic stiffness will be measured.See study design
What are the potential side effects?
While specific side effects are not listed here, previous studies suggest that MitoQ was well-tolerated by older adults. However, as with any supplement, potential side effects may include digestive discomfort or allergic reactions.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

Is enrollment in this experiment still open?

"Affirmative, the information located on clinicaltrials.gov suggests that this medical experiment is actively recruiting participants. This trial was first published in April 2021 and last modified in July 2022, with a total of 112 volunteers expected to be recruited from 1 site."

Answered by AI

How many persons are being included in this trial?

"Affirmative. According to data on clinicaltrials.gov, this investigation is still recruiting patients since its initial posting in April of 2021 and latest update in July 2022. The desired sample size involves 112 individuals from a single site."

Answered by AI

What potential risks come with the administration of MitoQ?

"MitoQ's safety is rated a 2, as the Phase 2 status implies that there are some studies confirming its safety but none attesting to its efficacy."
