Iron: While ten million people are iron deficient, that issue can be remedied with an improved diet. Most people get their daily iron from brown rice, beans, shrimp, beef, eggs, and even tofu. Taking more iron than needed through supplements can contribute to irregular heartbeat and even internal bleeding in extreme cases.
B Vitamins: Even though we need B12 to keep our nerves and blood cells healthy, being deficient can take a long time to happen because our daily needs are relatively small.
Vitamin E: Vitamin E is stored in the body for later if it’s not needed immediately after being consumed. Like others we’ve mentioned, a well-balanced diet will most likely nullify the need for supplementing.
