Introduction

Riboflavin (vitamin B2) was extracted from milk in 1935. It is now understood that it plays a vital role in energy and many other bodily functions.

Its role in energy production is four-fold. It functions in glucose and amino acid oxidation as well as in the synthesis of fatty acids. Riboflavin also helps metabolize thyroid hormones, which plays a role in the body’s metabolism. Riboflavin also has a role in repairing tissues.

Without Vitamin B2, a person may experience vitamin B2 anemia. Riboflavin deficiency may also lead to a decrease in the production of antibodies. Without riboflavin, the esophagus may be more susceptible to cancer. If there are low levels of riboflavin, the eyes may become overly-sensitive to light, causing watery, bloodshot and inflamed eyes. Blurred, tired eyes, as well as cataracts, have all been tied to a deficiency of riboflavin.

Since vitamin B2, as well as vitamin B1, has a significant impact on the nervous system, psychiatric patients may be prescribed high doses of these vitamins in order to ensure a well-functioning nervous system. Those suffering from carpal tunnel syndrome may also find benefit from supplementing with riboflavin, along with vitamin B3 and vitamin B6.

Deficiency Symptoms

Biological changes in the nervous system, skin, eyes and lips are early signs of deficiency of riboflavin. Eyes may tear or burn as well as experience early fatigue. The corners of the mouth may be sore with tiny cracks or lesions. Those who are experiencing depression, irritability, nervousness and moodiness may also be deficient in vitamin B2.

The recommended daily intake of riboflavin is 1.6 mg for both women and men. Depending on lifestyle, a person may need to increase his/her intake of riboflavin. For those who are on certain medications or consume alcohol may need to increase their consumption of riboflavin-rich foods. Those who exercise frequently may also have a greater need for riboflavin intake.

Sources

Whole grains are a good source of riboflavin. Foods like processed grains, however, are known to have low amounts. Other sources include spinach, beans, fish, poultry, eggs, cheese and yogurt. You may also want to try adding mushrooms to your salad or pizza, since they provide a source of riboflavin that is low in calories.
