What are Toxicity Symptoms for Vitamin B2?

Riboflavin or vitamin B2, is an easily absorbed, water-soluble micro-nutrient with a prominent role in maintaining human health. Vitamin B2 is a water-soluble vitamin, one that cannot be stored by the body except in insignificant amounts. It should be replenished daily to avoid deficiency.

It is required by the body to use oxygen and the metabolism of amino acids, fatty acids, and carbohydrates. Vitamin B2 is further needed to activate vitamin B6 (Pyridoxine), helps to create niacin and assists the adrenal gland. It may be used for red blood cell formation, antibody production, cell respiration and growth.

Even if you take excess levels of riboflavin through oral there is no potential harm according to the the Institute of Medicine at the National Academy of Sciences because the body stores only significant levels and the remaining is excreted. Although, toxic doses can be administered by injection any excess at nutritionally relevant doses is excreted in the urine, imparting a bright yellow color when in large quantities. A normal yellow discoloration of the urine is seen with an increased intake of this vitamin - but it is normal and harmless.
