Getting too much vitamin A

What happens if I don’t get enough vitamin A?



You may have heard of vitamin A but perhaps you're not sure of the benefits or how to get the right amount in your diet.  

It's vital to eat a [balanced diet](/healthy-diet/healthy-eating-and-balanced-diet) that includes vitamin A-rich foods to get enough of this essential vitamin.

## Why is vitamin A important?
Vitamin A helps the body work properly in a number of ways, including:

- helping with vision, especially in dim light
- protecting against illness and infection by supporting the immune system
- keeping the skin and other linings of the body, such as inside the nose, healthy

## Which foods are high in vitamin A?
Vitamin A is measured in micrograms (µg) of retinol equivalents (RE). The recommended daily allowance (RDA) of vitamin A for adults aged 19 to 64 is 700 µg a day for men and 600 µg for women – these are tiny amounts.

To make sure you’re getting the RDA of vitamin A, include a range of these vitamin A food sources in your diet: 
- liver and liver products: 100g of liver pâté contains around 7,322 µg of vitamin A, which is more than 1,000% of an adult’s RDA. Eating liver more than once a week can put you at risk of having too much vitamin A
- cheese: 100g of cheddar cheese contains 388 µg of vitamin A, just over half the RDA
- eggs: a serving of 2 boiled eggs weighing about 100g in total contains around 120 µg of vitamin A in total, which is around 20% of the RDA
- oily fish: 100g of grilled mackerel, for example, contains around 60 µg of vitamin A, which is about 10% of the RDA
- milk: 100ml of milk contains around 38 µg of vitamin A, which is about 5% of the RDA

Vitamin A is also available through eating foods rich in beta-carotene, which the body turns into retinol. Some of the best sources of beta-carotene are:
- yellow and red vegetables, such as carrots, red peppers and sweet potatoes 
- green leafy vegetables, like spinach
- yellow fruits, including apricots, mango and papaya

## Getting too much vitamin A
Some research suggests that getting more than the RDA of vitamin A, especially over several years, may weaken your bones as you age. This is especially important for older people, who may be at risk of [osteoporosis](/healthy-bones/osteoporosis), to be aware of.

Many multivitamins, such as fish liver oil, contain vitamin A. You should think about your total vitamin A intake, from both food and supplements, when working out your vitamin A consumption, which should not be more than 1,500 µg a day.

If you’re pregnant or trying to get pregnant, avoid liver and liver products – these foods are very high in vitamin A, which can be harmful to an unborn baby.
