Essential Vitamins for Longevity
Complete evidence-based guides on all 13 essential vitamins for optimal health, energy, and healthy aging. Discover the nutrients your body needs daily.
Vitamins are organic compounds essential for life. Unlike minerals, your body cannot produce most vitamins—they must come from food or supplements. Each vitamin plays unique roles in metabolism, immune function, cellular repair, and longevity.
Research shows that optimal vitamin levels are associated with reduced risk of chronic disease, better cognitive function, stronger bones, and increased lifespan. Our comprehensive guides cover the science, optimal dosages, and best food sources for each vitamin.

Understanding how vitamins support healthy aging
Energy Production
B vitamins are essential cofactors in converting food into cellular energy (ATP). Without them, metabolism slows dramatically.
Immune Defense
Vitamins C, D, and A support immune cell function and help protect against infections and disease.
Bone Health
Vitamin D and K work together to regulate calcium and maintain strong bones throughout life.
Brain Function
B12 and folate support cognitive function, memory, and help prevent age-related mental decline.
Research Insight: A 2021 meta-analysis in the American Journal of Clinical Nutrition found that adequate vitamin D levels were associated with a 25% reduction in all-cause mortality. Similarly, optimal B12 status has been linked to better cognitive function in aging populations.
