Vitamins serve crucial functions in many bodily processes, and without them, many of those processes fail. Depending on the vitamin and a person's diet, sometimes these nutrients must be obtained through supplements because our bodies can’t produce them and the foods we eat don't provide sufficient amounts. However, many people do not realize that vitamins interact with each other. Some vitamin pairings provide a significant boost in the efficacy of both vitamins, while other pairings essentially make both substances useless. Additionally, medications and foods can manipulate the effectiveness of vitamins.


1. Pairings with Iron

One of the most vital minerals for the human body is iron. It plays a role in creating energy from nutrients and contributes to the transmission of nerve impulses that control the body. Calcium and zinc both negatively affect the body’s absorption of iron. If a person takes vitamin A, they can improve their iron absorption. Another benefit of this pairing is higher levels of hemoglobin that improve red blood cell function. Vitamin C also improves the absorption of iron in the gastrointestinal tract.
