Summary
Brief summary
To Evaluate the Absorption Efficacy Characteristics and Further Safety Over a 6-hour period of Coenzyme Q10 [100 mg administered as ONE dose orally] from SIX study Preparations to Healthy Participants. The study aims to find out whether;
1) Different Over The Counter (OTC) Coenzyme Q10 products absorb differently as assessed by blood serum levels
2) Different modes of Coenzyme Q10 oral preparations [i.e. as a liquid or capsule] can provide the best delivery vechile
3) and what forms of Coenzyme Q10 such as liquids, capsules or other forms are acceptable to participants
