Has any significant acute or chronic coexisting health conditions that would prevent them from fulfilling the study requirements, put the Participant at risk or would confound the interpretation of the study results as judged by the investigator on the basis of medical history and routine laboratory test results. Excluded health conditions include: * a. Major illness/surgery in the 12-weeks prior to screening * b. Diagnosed cardiovascular disease (NHYA Class III or IV congestive heart failure, atrial fibrillation, uncontrolled arrhythmia, uncontrolled hypertension) * c.

Prohibited supplements include: * a. Mitopure® containing supplements * b. Supplements for muscle strengthening/building or mitochondrial boosting supplements (e.g. high protein, Vitamin B3 \[and precursors\], L-carnitine, CoQ10, NAD+, resveratrol) * 12\. Blood donation in the 8-weeks prior to screening. * 13\. Individuals who, in the opinion of the investigator, are considered to be poor attendees or unlikely for any reason to be able to comply with the study. * 14\. Participants may not be participating in other clinical studies. If the participant has previously taken part in an experimental study (physical or muscle performance), the Investigator must ensure sufficient time has elapsed before entry to this study to ensure the integrity of the results.
