Effects of Miricell Supplementation on Biomarkers of Healthy Aging and Autophagy

The goal of this clinical trial is to learn if a dietary supplement called Miricell works to improve cellular health and signs of healthy aging in adults. It will also learn about the safety of Miricell. The main questions it aims to answer are: * Does Miricell improve markers of autophagy(definition), which is the body's natural process for recycling damaged cells? * Does Miricell support brain health, metabolic health, and visible signs of aging? * What medical problems, if any, do participants experience while taking Miricell? Researchers will compare Miricell to a placebo (a look-alike capsule that contains no active ingredients) to see if Miricell works better to support healthy aging. Participants will: * Take either one Miricell capsule or a placebo every day for 12 weeks with a morning meal. * Visit the research clinic four times over the course of the study for checkups and tests. * Complete memory and thinking tests, track their daily physical activity, and give blood samples to measure health changes.
