What interferes with the absorption of biotin
– Dietary avidin, a glycoprotein contained in in raw egg whites, tightly binds to dietary biotin and interferes with the absorption of the vitamin in the gastrointestinal tract, the nutritionist explains. “But the heat treatment of eggs denatures the avidin and it no longer interferes with the absorption of biotin.
Biotin absorption may also interfere with artificial sweetener saccharin – with regular use.
– interferes with the absorption of biotin also alcohol and some sulfur-containing food preservative additives (E221-E228), more precisely, sulfur oxide formed from them when products containing these additives are heated (juices, preserves and jams, for example), says Irina Kononenko.
Biotin and drugs
Some medications can have an adverse effect on biotin levels.
“For example, treatment with anticonvulsants for at least 1 year has been associated with significantly lower levels of biotin,” explains the nutritionist. – It is possible that treatment with anticonvulsants increases biotin catabolism, resulting in decreased biotin status and slowing down its absorption in the intestine.
