Vitamin B2 (riboflavin)
Riboflavin, also known as vitamin B2, is one of the B vitamins. Here is what it does, where it is found in food and how much adults need, based on NHS guidance.
What it does
- Helps keep skin, eyes and the nervous system healthy
- Helps the body release energy from food
Good food sources
- Milk and plain yoghurt
- Eggs
- Mushrooms
- Fortified breakfast cereals
How much do adults need?
Adults aged 19 to 64 need about 1.3 mg a day (men) and 1.1 mg a day (women). Riboflavin cannot be stored in the body, so you need it in your diet every day.
Good to know
- UV light can destroy riboflavin, so keep these foods out of direct sunlight.
- Taking 40 mg or less a day of riboflavin from supplements is unlikely to cause any harm.
