Biotin (Vitamin B7) daily dose

Biotin is a vital part of a healthy metabolism and creating important enzymes. Clinical  signs  of deficiency include dermatitis of an erythematous and seborrheic type; conjunctivitis; alopecia; and  central  nervous  system  abnormalities  such as  hypotonia, lethargy,  and  developmental delay in infants and depression, hallucinations, and paresthesia of the extremities in adults. Toxicity is not a problem because of limited intestinal absorption of biotin.
