Vitamin B2 (also called as riboflavin) is part of the B-complex group of vitamins. Riboflavin is produced in the body by the intestinal flora and is easily absorbed, although very small quantities are stored, so there is a constant need for this vitamin.

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

The limited capacity to absorb orally administered riboflavin precludes its potential for harm. Riboflavin intake of many times the RDA is without demonstrable toxicity.
A normal yellow discoloration of the urine is seen with an increased intake of this vitamin – but it is normal and harmless.

Potential symptoms of Riboflavin overdose

There is no known toxicity to Vitamin B2. Because Vitamin B2 is a water-soluble vitamin, excess amounts are easily excreted by the body in the urine.

Potential side effects of very high doses may include: itching, numbness, burning or prickling sensations, and sensitivity to light. Excess riboflavin excreted in the urine causes it to become bright yellow in color, which many people notice when they take B vitamin supplements.
