Health should be approached as a holistic ecosystem where various biological systems interact and affect overall well-being. Understanding the microbiome's influence on health is crucial, as it links to nearly all known conditions, yet remains under-researched and under-discussed. The hallmarks of aging—such as inflammation, microbiome changes, mitochondrial function, DNA integrity, and nutrient regulation—are fundamental drivers of age-related issues. Embracing advances in epigenetics highlights the importance of gene regulation in health management, where lifestyle and environmental factors can modulate genetic expression, ultimately allowing for the optimization of biological age and health outcomes.
