Vitamin B2


The B vitamins are a group of 8 all water-soluble vitamins, all crucial for cell metabolism, converting food into energy, the normal functioning of the central nervous system and the formation of red blood cells.

What might a low result mean?

Although rare, vitamin B2 deficiency can occur. Symptoms include anaemia, fatigue, slowed metabolism, nerve damage, a swollen tongue, mouth sores and cracks, skin inflammation, sore throat, swelling of the mucus membranes and changes in mood.

What might a high result mean?

Elevated levels of B2 is likely to be due to over-supplementation. Although high levels are rarely dangerous, vitamin B2 supplements can interact with other medication and cause a reaction.

How might I improve my result?

Low vitamin B2 levels can be improved by incorporating more foods rich in vitamin B2 into your diet. Vitamin B2 or riboflavin is a water-soluble vitamin found in foods like almonds, whole-grains, mushrooms, certain dairy products, eggs, brewer's yeast and some green vegetables.
