Supplements for Mortality

What the Research Shows

Current large-scale clinical research generally shows that most dietary supplements do not significantly reduce the risk of all-cause mortality in the general population. While many nutrients are essential for health, taking them as isolated supplements often fails to produce the life-extending benefits seen with whole-food diets. Evidence for specific supplements varies. For example, there is insufficient evidence to support the use of Vitamin D for reducing overall mortality. Other popular supplements often show weak or conflicting results in long-term mortality trials, as the benefits are frequently limited to individuals with severe clinical deficiencies rather than the general public. These findings are limited by the fact that many studies are short-term or rely on observational data, which can be misleading. Because individual health needs vary and long-term data on many compounds are lacking, it remains difficult to definitively prove that any single supplement increases lifespan for the average healthy adult.
