Dark chocolate, particularly varieties with minimal sugar, is rich in polyphenols that support mitochondrial health. Coffee offers numerous benefits, including improved insulin resistance and gut microbiome support, while also enhancing melatonin levels, which can aid in mitochondrial regeneration. The importance of melatonin extends beyond sleep, serving as a powerful antioxidant, especially in aging populations. Understanding the decline in melatonin levels is crucial for promoting longevity and overall health.
