Other information

Cradle cap in breastfed babies seems to improve when the mother eats more biotin rich foods.


No known toxicity for levels found in supplements.

High doses of single B-vitamins may deplete other B-vitamins; therefore if high doses are required, supplementation with a multivitamin or B-complex is advised.

Please note: Especially in babies, intestinal defects in absorption or cell binding can lead to deficiencies even where intake and production by intestinal bacteria are sufficient. Both adults and children are at greater risk of deficiency in cases of long-term therapy with prescribed antibiotics.


Factors which deplete levels, impair absorption and/or inhibit activity:

Consumption of raw egg whites


Oral contraceptives




Tea and coffee
