Sleep is the body’s primary cellular repair window, with autophagy and mitophagy peaking during deep sleep stages. Research shows that Urolithin A may enhance sleep quality by supporting mitochondrial function in brain cells, leading to more restorative sleep. To maximize cellular repair: maintain consistent sleep/wake times, keep your bedroom cool (65-68°F), minimize blue light exposure 2 hours before bed, and avoid large meals close to bedtime. Studies indicate that people who combine quality sleep habits with Urolithin A show superior improvements in biomarkers of cellular health compared to those focusing on sleep alone.
