Vitamin B2 (riboflavin)
Men need around 1.3 milligram a day and women, 1.1 milligrams of vitamin B2 (riboflavin) per day.
The 2016 UK National Diet and Nutrition Survey found that while most people get enough vitamin B2 (riboflavin), many are falling short. Low intakes are particularly high among breakfast-skipping teens with one in five teenage girls and one in 12 boys missing out. But it’s not just young people missing out, 13 per cent of women and three per cent of men aged 19 to 64, and five per cent of older adults are also failing to meet targets.
Vitamin B2 (riboflavin) is one of the B vitamins, which are all water soluble. It is essential for energy metabolism, is important for growth, healthy eyesight and red blood cell production. It is also essential for the body to utilise vitamin B6 and is an antioxidant, protecting your cells and DNA from free radicals that can cause damage. The body stores only small amounts of riboflavin in the liver, heart and kidneys, so you need it in your diet every day.
Riboflavin is found in animal and plant foods. You can’t have too much of it from food but if you have very high doses in supplements, it can colour your urine bright yellow (which is harmless and disappears as your body flushes out the excess).
No, a healthy vegan diet containing the foods below on a daily basis will cover your needs.
The best plant sources of riboflavin include yeast extract (Marmite/Vegemite), nutritional yeast, quinoa, muesli, fortified vegan breakfast cereals, fortified soya milk, avocado, almonds, wild rice, mushrooms and mange-tout peas.
Nutritional yeast is a food additive that can be used as a condiment or ingredient. It is made from yeast grown on molasses and then harvested, washed and heated to kill or ‘deactivate’ it. It doesn’t froth or grow like baking yeast as it is inactive. It is sold in tubs of flakes that can be sprinkled on dishes or added to sauces. Very popular with vegans, it even has its own nickname – nooch! A five gram teaspoonful of nutritional yeast provides over 70 per cent of your daily requirement of riboflavin. Buy one that’s fortified with vitamin B12 to cover all bases!
