As measles cases rise again globally, many are looking for alternative ways to protect themselves – and some have turned to vitamin A.
But does this nutrient actually prevent the disease, or is it just hype? Here’s what health authorities and experts have to say.
Most people already get enough vitamin A
A well-balanced diet usually provides sufficient vitamin A.
Foods like eggs, dairy products, fish, and brightly colored vegetables contain high amounts of the nutrient, especially in high-income countries like the U.S.

Cod liver oil is not a miracle cure
While cod liver oil does contain both vitamins A and D, it’s not a magical solution.
In fact, because these are fat-soluble vitamins, they can build up in the body and become toxic when consumed in large amounts.
Too much vitamin A can be dangerous
Overdosing on vitamin A is not harmless. Side effects may include nausea, liver damage, skin issues, and even brittle bones.
This makes it crucial to avoid exceeding the recommended limits.

Daily vitamin A needs vary by age
Children typically need around 300 micrograms daily, while adult men require about 900 mcg and women about 700 mcg.
Consistently taking more than 3,000 mcg per day can lead to toxicity in adults.
Supplements are only needed for a few people
Most people do not need vitamin A supplements.
Exceptions include premature infants and individuals with conditions that interfere with nutrient absorption, such as celiac disease or Crohn’s disease.

Vitamin A does not prevent measles
Despite its immune-boosting properties, vitamin A cannot stop someone from getting infected with measles.
Health experts are clear: this vitamin is not a substitute for vaccination or other preventive measures.
Vitamin A may help once infected
When measles has already taken hold, vitamin A can play a supportive role.
Doctors often recommend two oral doses for children under the age of two with severe symptoms, especially because measles can deplete vitamin A levels in the body.

WHO supports vitamin A for treatment
The World Health Organization, WHO, officially recommends vitamin A for the treatment of measles – for both children and adults.
However, they do not endorse it as a way to prevent the disease.
Vaccination remains the only effective protection
Health professionals stress that vaccines are still the only proven way to protect yourself and your children from measles.
Vitamin A supplements cannot replace the need for immunization.

The MMR vaccine offers lifelong protection
The Centers for Disease Control and Prevention (CDC) advise giving the first MMR dose to children at 12–15 months and a second dose between ages 4 and 6.
Unvaccinated teens and adults should also get one or two doses, spaced 28 days apart.
