Vitamin B2 - otherwise known as Riboflavin
Potential for deficiency
A Vitamin B2 deficiency can happen due to numerous factors, such as over-dieting, abusing alcohol, liver disorders, and kidney dialysis. The elderly, the chronically ill and alcoholics are groups who may be especially susceptible to riboflavin deficiency. Women who take birth control pills may also benefit from supplementation - the body's ability to absorb riboflavin is believed to be reduced when taking birth control pills. Riboflavin deficiency is particularly widespread among alcoholics because chronic alcohol abuse lowers the quantity of Vitamin B2 (and other nutrients such as Vitamin B1) that is absorbed by the body.
What does Vitamin B2 do?
Vitamin B2 (Riboflavin) is one of 8 in the B-Vitamin family. Just like Vitamin B1 (Thiamin) It is involved in vital metabolic processes in the body, and is necessary for energy production and normal cell function and growth. We know that Vitamin B2 helps support adrenal function, helps calm and maintain a healthy nervous system, and facilitate key metabolic processes, including helping to turn food into energy. Riboflavin is also important to help maintain normal vision and normal red blood cells.
The European Food Safety Authority (EFSA) confirms that clear health benefits have been established for the dietary intake of Riboflavin (Vitamin B2) in contributing to:
- normal energy-yielding metabolism
- normal metabolism of iron in the body
- the maintenance of normal skin and mucous membranes
- the maintenance of normal red blood cells
- the maintenance of normal vision
- the protection of cell constituents from oxidative damage
- the maintenance of the normal function of the nervous system
- the reduction of tiredness and fatigue.
Whole grains, milk, cheese,eggs, mushrooms, dark green vegetables (particularly broccoli, spinach and asparagus), meats, liver (and other organ meats), fish and poultry.
Riboflavin (Vitamin B2) is a water-soluble vitamin and as such, it is unlikely to reach toxic levels. There is little danger of riboflavin toxicity when it is taken orally.

- Throat swelling/soreness
- Swollen tongue
- Skin cracking (including cracked corners of the mouth)
