Which vitamins can you overdose on?

It's possible to overdose on all vitamins. An "overdose" means that someone has exceededrecommended daily allowances(RDAs) of a vitamin or mineral.

Most multivitamins contain the RDA (or close to it) of each vitamin and mineral. So, if you take more than the serving size (usually one vitamin), you can overdose on all the vitamins that make up your multivitamin. So it's possible to have multiple vitamin overdoses from taking a single pill.

Some vitamin overdoses are more dangerous than others. These particular vitamins in the following chart can be dangerous for adults and children. Let's take a closer look at what they do in the body and what an overdose might look like.

What are the symptoms of a vitamin overdose?

The symptoms of a vitamin overdose depend on the vitamin and the amount taken. Some vitamin overdoses start off with mild symptoms like stomach upset and vomiting, and then progress into more serious symptoms. Other vitamin overdoses cause very few or no symptoms.

If you think you or a family member has overdosed on vitamins, don't rely on symptoms to make a decision. Symptoms may become serious very quickly. It's safest to get help right away.

What to do if you took too many vitamins

If you or your child just ate a bunch of vitamins - whether gummies or another kind of vitamin - what should you do? First, call your local poison control center orPoison Controlat1-800-222-1222. They can let you know if you should go to an emergency room for immediate care.

If you or your child took vitamins without iron and vitamin A, you might be able to remain at home. But you shouldn't make this decision on your own, since certain vitamin overdoses can be life-threatening, especially in young children.

Care at home If Poison Control says you or your child can remain at home, you should be on the lookout for vitamin overdose symptoms. These can include:

• Stomach upset
• Nausea and vomiting
• Diarrhea
• Flushing(usually due to vitamin B3/niacin)
• Change in urine or stool color
• Bad headache
• Dizziness
• Muscle pain

Your child probably won't want to eat while having these symptoms. But it's important to make sure your child stays hydrated, so encourage them to drink plenty of fluids. You may want to use oral electrolyte solutions.

If your child is showing signs of dehydration, call a healthcare professional immediately. In kids, this might include:

• Not urinating or making wet diapers as much as usual
• Acting more tired or sleepy
• Dry lips and mouth
• Making less tears when crying

Care in the emergency room If Poison Control recommends getting immediate care, go to your nearest emergency room. You may need:

• Bloodwork
• X-rays to look for signs of pill fragments
• A procedure called GI tract irrigation to make the vitamins leave the body quicker
• Medications to bind vitamins (especially iron) and remove it from the body

How many vitamins should you take?

You should always take the recommended amount of vitamins suggested on the supplement bottle, usually 1 to 2 a day. If you take more than that in 1 day, you've taken too many.

Experts from theFood and Nutrition Boardat the Institute of Medicine have developed guidelines that cover how much of each vitamin a person needs each day.

These guidelines include:

• Recommended daily allowance (RDA):This is the average amount of each vitamin or mineral a person needs in a day.
• Tolerable upper intake limit (UL):This is the highest amount of vitamin or mineral a person can safely consume each day without it making them sick.

Your vitamins shouldn't exceed the RDA for any single vitamin or mineral. It's also important to keep your diet in mind as you choose vitamins. It's possible to exceed your upper intake limit from your dietary intake plus your vitamins.

Vitamin and iron guidelines for children younger than 1 year

The American Academy of Pediatrics recommends that all babies receive a vitamin K injection at birth. But if your baby didn't receive avitamin K shot, a healthcare professional may recommend oral vitamin K supplements.

Otherwise, young children don't typically need vitamins. However, infants who are bornprematurelyusually need daily iron supplements. And the American Academy of Pediatrics recommendsdaily vitamin D supplementsfor nursing infants. Infants who are exclusively nursing may also need iron supplements after 4 months of age until they're eating iron-fortified foods several times a day. Infants who takeinfant formuladon't usually need any extra vitamins.

Frequently asked questions
