Riboflavin deficiency is known as pellagra, usually found in those who do not consume a diet rich in organ meats, leafy greens, and whole grains. It is seen in elderly, alcoholics, those with chronic liver disease, and those on total parenteral nutrition. Deficiency may be associated with severe lactic acidosis, especially in HIV patients on triple antibiotics. It also functions as an antioxidant. Riboflavin adsorption is decreased in hyperthyroidism.

Fasting for 10-12 hours required.
