Very Low Risk for breastfeeding

Safe. Compatible.
Minimal risk for breastfeeding and infant.

It is an essential co-enzyme 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).

Biotin is found in the non-fat fraction of breast milk in an amount of 5 to 9 μg/L.

Biotin is widely distributed in most foods with a very rare occurrence of deficiency 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.

With an adequate and comprehensive diet, the consumption of vitamin supplementation is not necessary.


We do not have alternatives for Biotin since it is relatively safe.

Suggestions made at e-lactancia are done by APILAM´s pediatricians and pharmacists, and are based on updated scientific publications.
It is not intended to replace the relationship you have with your doctor but to compound it.

Jose Maria Paricio, Founder & President of APILAM/e-Lactancia

Your contribution is essential for this service to continue to exist. We need the generosity of people like you who believe in the benefits of breastfeeding.

Thank you for helping to protect and promote breastfeeding.
