Potassium is a crucial biomarker when it comes to longevity. It plays a vital role in maintaining proper cellular function and electrolyte balance, which are essential for overall health and longevity. Low levels of potassium have been linked to an increased risk of hypertension, stroke, and cardiovascular disease, all of which can significantly impact a person’s lifespan. Monitoring and maintaining optimal potassium levels through diet and supplementation can help support healthy aging, reduce the risk of age-related diseases, and improve overall longevity. As a longevity expert, understanding and addressing potassium levels is essential for promoting longevity and well-being in individuals.
