Biotin, just like other vitamins, is needed for the proper growth and development of the fetus. It was earlier believed that the deficiency of this vitamin is quite rare, but now, it has been found that pregnant women tend to be deficient in it.

Biotin participates in vital metabolic processes in humans, including gluconeogenesis, fatty acid synthesis, and amino acid breakdown, by serving as a prosthetic group for enzymes involved in energy metabolism (3).

Maternal health can be at risk due to biotin deficiency, which generally increases the likelihood of various health conditions and even birth defects during pregnancy, making it one of the most essential vitamins (4).

According to the Institute of Medicine, pregnant women must take in at least 30 mcg of biotin on a daily basis (5). Just like iron and folates like folic acid, biotin also makes for a crucial nutrient needed during pregnancy. In fact, a lot of women also tend to be deficient in this important vitamin during pregnancy because the body breaks down biotin more quickly during this period.

protip_icon Be watchful
Avoid consuming raw egg whites in excess during pregnancy, as they can interfere with biotin absorption and lead to acquired biotin deficiency (13).

The Linus Pauling Institute and the American Journal of Clinical Nutrition state that around 1/3rd to ½ of pregnant women are deficient in biotin, and this deficiency most commonly occurs during the late pregnancy. (6)

A deficiency of biotin is linked to several health problems including:

  • Poor hair and nail health
  • Increased risk of seborrheic dermatitisiA common skin disease in children that causes dandruff, scaly patches, and inflamed skin on the body.
  • Diabetes
  • Cleft Palate/LipsiA type of congenital disability that results in underdeveloped lips or mouth. – A type of congenital disability that results in underdeveloped lips or mouth.
  • Fatigue
  • Reduced appetite
  • Depression
  • InsomniaiA sleep disorder that makes it difficult to fall asleep, stay asleep, or get a sound sleep. (7)

When it comes to pregnancy, biotin deficiency may also lead to birth defects. It has been found that a deficiency of this crucial vitamin may lead to birth defects in animals, particularly conditions such as skeletal deformitiesiAbnormality in the size, shape, growth, or alignment of the bones . , cleft palate, cleft lip, etc. (8)
