Vitamins, organic compounds, aid in cell functions and reactions. Minerals, inorganic elements, are found in everything from DNA to muscle contractions. Foods like carrots and milk provide both vitamins and minerals. Overdosing is easier with fat-soluble vitamins (A, D, E, K) than water-soluble ones (C) as they stay longer in the system.
