Very Low Risk
Biotin, vitamin B7 or vitamin H is an essential coenzyme for fat metabolism and other metabolic reactions, which is classified among the vitamin B group.
Recommended daily allowance is 10 to 200 μg according to some authorities and 30 to 100 μg to some others: 5 at15 μg for infants, 20 to 30 μg for children, 30 μg for pregnant women and 35 μg for lactating mothers (Saleem 2021, Sauberan 2019, Ares 2015, Perry 2014, UMMC 2013, Zempleni 1999).
Biotin is found in the non-fat fraction of breast milk in an amount of 5 to 10 μg/L (Sauberan 2019, Sakurai 2005, Mock 1992) with a higher concentration in mature milk than in colostrum but without significant differences between preterm milk and full-term milk (Salmenperä 1985, Ford 1983), nor between different countries (Nguyen 2020).
Biotin is widely distributed in many foods. Foods rich in biotin are egg yolk, liver, cereals (wheat, oats), vegetables (spinach, mushrooms), rice, dairy products, and breast milk; intestinal bacteria can produce biotin (Saleem 2021), so its deficiency is very rarey among people who are on adequate diet, nor any case of intoxication is known even with higher doses than recommended for daily intake.
At date of latest update, relevant data related to breastfeeding were not found. However, because lack of toxicity a risk due to consumption at recommended dose is unlikely.
Breastfeeding can be continued even with high doses (2.5 mg/day) of biotin (Sauberan 2019).
With an adequate and comprehensive diet, the consumption of vitamin supplementation is not necessary.
