As measles cases rise again in several U.S. communities, concern and confusion are also increasing—especially around prevention and treatment. One piece of misinformation making the rounds has pushed some people to take high doses of vitamin A, thinking it will keep measles away or help cure it.

But taking too much of this nutrient isn’t just ineffective—it can be dangerous.

Why People Are Turning to Vitamin A

Measles is a highly contagious viral disease. It spreads easily through the air when someone coughs, sneezes, or breathes near others. With symptoms like fever, cough, runny nose, and a widespread rash, it can become severe—especially for young children.

While there’s no specific antiviral treatment for measles, doctors sometimes recommend vitamin A for people who are malnourished or have a deficiency. This can help the immune system fight off the infection more effectively.

But here’s the issue – that clinical use of vitamin A is being misunderstood. Some people assume more is better and begin taking large doses on their own. That’s where the real problem begins.

Too Much Vitamin A Can Lead to Toxicity

Vitamin A is fat-soluble, meaning the body stores what it doesn’t use right away. That may sound like a good thing, but it also means the nutrient can build up to unsafe levels over time.

When the body stores too much vitamin A, it can lead to a condition called hypervitaminosis A, or vitamin A poisoning. This can cause a wide range of symptoms, including:

– Nausea and vomiting
– Dizziness or blurred vision
– Liver damage
– Bone thinning
– Headaches
– Skin irritation

The effects can be even more severe for children, who are more sensitive to overdoses.

Poison Centers Are Getting More Calls

Poison control centers across the country receive hundreds of calls each year related to vitamin A. According to experts, that number could go up as more people turn to supplements without guidance.

Christopher Holstege, a physician and medical director with years of experience in toxicology, warns against this approach:

“People assume vitamins are always safe because they’re sold over the counter, but taking more than your body needs can be risky. Unless there’s a diagnosed deficiency, there’s rarely a reason to take high doses.”

Misinformation Is Part of the Problem

Online forums, social media posts, and even word-of-mouth are spreading myths about vitamin A’s ability to cure or prevent measles. While there’s research supporting the use of this vitamin to support recovery in children who are malnourished, that doesn’t mean it should be used in large quantities by healthy individuals.

In fact, self-dosing with high levels of vitamin A without a doctor’s oversight can backfire, making the situation worse instead of better.

What Actually Works Against Measles

The most effective way to stay protected from measles isn’t through supplements—it’s through vaccination. The MMR (measles, mumps, rubella) vaccine remains the strongest defense available.

Here’s what’s important to know about the MMR vaccine:

– Two doses provide about 97% protection against measles.
– One dose gives roughly 93% protection.

The vaccine is safe and widely recommended by health professionals.

Getting vaccinated not only protects individuals but also helps prevent outbreaks in the community.

How Much Vitamin A Is Too Much?

It’s easy to assume that if a little helps, a lot will help more. But when it comes to vitamins, that approach can cause serious harm.

Here’s a quick look at the recommended daily intake for vitamin A:

– Adults: About 700 to 900 micrograms (mcg) per day
– Children: Varies by age, usually between 300 and 600 mcg

Supplements often contain much more than this, and some people take several at a time. That’s when trouble starts.

Too much vitamin A can build up in the liver and other organs, and it doesn’t get flushed out quickly. Taking megadoses, especially over long periods, can trigger toxic effects even if symptoms aren’t obvious at first.

Safer Ways to Support the Immune System

To stay healthy and keep the immune system functioning properly, there are far safer and more effective approaches than turning to high-dose supplements.

Prioritizing quality sleep, maintaining a balanced diet that includes plenty of fruits, vegetables, whole grains, and lean proteins, staying well-hydrated, and getting regular physical activity all play important roles in overall wellness. Practicing good hygiene, like washing hands frequently, also helps reduce the spread of germs.

If there’s concern about a possible vitamin deficiency, the smartest step is to consult a healthcare provider. They can evaluate what’s needed, recommend an appropriate dose, and keep an eye on vitamin levels to help prevent any health issues.

Be Cautious with Supplements

The renewed focus on vitamin A as measles makes headlines highlights a bigger issue—how easily misinformation can spread. While it’s understandable to want extra protection during a health scare, taking matters into your own hands without medical advice can do more harm than good.

Stick to science-backed strategies, keep vaccines up to date, and treat supplements as what they are—support tools, not cures.
