12 Unexpected Causes of Vitamin Deficiencies You Might Be Missing

5. The Genetic Factor: How DNA Affects Vitamin Needs

Genetics can significantly influence an individual's vitamin requirements and susceptibility to deficiencies. Certain genetic variations can affect the metabolism of specific vitamins, leading to increased needs or reduced absorption. For example, mutations in the MTHFR gene can impair the conversion of folic acid to its active form, necessitating higher intake of folate-rich foods or supplements for those affected. Genetic testing can provide valuable insights into an individual's unique nutritional needs, allowing for personalized dietary and supplementation strategies. By understanding their genetic predispositions, individuals can take proactive steps to address potential deficiencies and optimize their health. This personalized approach to nutrition underscores the importance of considering genetic factors when evaluating vitamin status and developing dietary plans.
