What Happens If You Take Too Many Vitamins?

It’s important to take all the vitamins and minerals you can, but there’s a limit. According to the Food and Nutrition Board of the National Academies, the upper daily limit of a vitamin is 35 milligrams. If you’re taking more than that, you may experience gastrointestinal problems. The higher the dose, the more serious your symptoms will be. If you notice these symptoms, consult a doctor immediately.

Multivitamins increase your intake of certain nutrients

Too much vitamin D is the most common cause of vitamin D toxicity. High levels of vitamin D can lead to hypercalcemia, which causes bone pain and muscle weakness. Too much vitamin A can also lead to irregular heartbeat and dizziness. Too much vitamin E is toxic, and can lead to hemorrhagic stroke. The recommended daily allowance for adults is 1,100 milligrams of vitamin E.

Remarks

Vitamin A is the most common cause of vitamin overdose. Too much vitamin A can lead to dermatitis, hair loss, difficulty walking, and even dizziness. It can also cause nausea, vomiting, and heart palpitations. In addition to a possible adverse reaction, excessive vitamin D can cause a variety of symptoms. The most obvious symptoms of an overdose of this vitamin are muscle weakness and constipation.
