• Inadequate intake of biotin-rich foods
• Gastrointestinal disorders such as inflammatory bowel disease and celiac disease that affect nutrient absorption
• Prolonged use of antibiotics or anticonvulsants that can disrupt the gut microbiome and reduce biotin production

Treatment:

The treatment of biotin deficiency typically involves supplementation of biotin-rich foods or biotin supplements. Some biotin-rich foods include eggs, almonds, sweet potatoes, spinach, and whole grains. In severe cases of biotin deficiency, high doses of biotin supplements may be recommended.

Prevention:

Biotin deficiency can be prevented by ensuring an adequate intake of biotin-rich foods or supplements. It is recommended that adults consume 30 mcg of biotin daily. People with gastrointestinal disorders or those taking antibiotics or anticonvulsants should consult their healthcare provider regarding biotin supplementation.
