Biotin is an essential nutrient for the human body, functioning as a key coenzyme for various carboxylases. It plays a pivotal role in metabolizing fats, carbohydrates, and amino acids—facilitating gluconeogenesis to produce glucose, regulating lipid synthesis as a component of the rate-limiting enzyme in fatty acid production, and promoting the deamination of amino acids like leucine and nucleic acid metabolism. Additionally, it contributes to forming retinal required by photoreceptor cells, supports immune system repair, and benefits infant development and cardiovascular health.
Under normal circumstances, the human body obtains sufficient biotin through diet: free biotin is directly absorbed by the intestines, while bound biotin is released with the help of intestinal flora before absorption, forming a dual pathway to ensure supply. However, specific groups need additional supplementation due to increased physiological demands or impaired absorption.
Based on recommendations from the European Food Safety Authority (EFSA) and Mayo Clinic, lactating women are a priority group with a daily intake of 45μg—higher than the 40μg for adults (including pregnant women)—to meet both their own needs and those of breastfeeding. Adolescents require 35μg/day during rapid growth. For children, 6μg/day is recommended for infants over 6 months, 20μg/day for 1-3 years olds, and 25μg/day for 4-10 years olds, which can be ensured through proper feeding or supplements.
Furthermore, individuals with poor intestinal function, those taking long-term antibiotics (which may disrupt intestinal flora), or those with diets lacking biotin-rich foods should consider supplementation under professional guidance. It’s crucial to adhere to recommended doses: 30-100μg/day for adults and age-appropriate amounts for children. Excessive intake may cause adverse effects, so supplementation should be tailored to individual needs.
