Do you suffer from scaly red skin round the eyes, nose, mouth and genitals?
If you do, you may be deficient in BIOTIN
What is Biotin?
Although biotin deficiency is very rare, the human requirement for dietary biotin has been demonstrated in two different situations: prolonged intravenous feeding without biotin supplementation and consumption of raw egg white for a prolonged period (many weeks to years).
Avidin is a protein found in egg white, which binds biotin and prevents its absorption. Cooking egg white denatures avidin, rendering it susceptible to digestion, and unable to prevent the absorption of dietary biotin.
Symptoms of biotin deficiency include hair loss and a scaly red rash around the eyes, nose, mouth, and genital area. Neurological symptoms in adults have included depression, lethargy, hallucination, and numbness and tingling of the extremities. The characteristic facial rash, together with an unusual facial fat distribution, have been termed the "biotin deficient face" by some experts. Individuals with hereditary disorders of biotin metabolism resulting in functional biotin deficiency have evidence of impaired immune system function, including increased susceptibility to bacterial and fungal infections.
Biotin is a water-soluble vitamin, generally classified as a B-complex vitamin. After the initial discovery of biotin, nearly forty years of research were required to establish it as a true vitamin. Biotin is required by all organisms but can only be synthesized by bacteria, yeasts, molds, algae, and some plant species.
In its physiologically active form biotin is attached at the active site of four important enzymes, known as carboxylases. Each carboxylase is a catalyst for an essential metabolic reaction.
