Understanding Biological Age vs. Chronological Age

Your birthday doesn’t tell the whole story. While chronological age is just the number of years you've lived, biological age reflects how well your body is actually aging—down to your cells and DNA. It’s influenced by lifestyle, environment, and epigenetic factors, making it a more accurate marker of overall health. At Genestica, we believe this distinction matters. Why? Because biological age is changeable. It can go up or down based on how you live your life. In this article, we’ll break down the key differences and explain why tracking your biological age is one of the smartest things you can do for your long-term health and vitality.
