Does Biotin Deficiency Cause Hair Loss?

Biotin is a B vitamin and water-soluble. It is also called vitamin H or vitamin B7. It plays a vital role in facilitating several metabolic processes in the body. Certain enzymes in our body need biotin to break down carbohydrates and fats into glucose. As we all know, every cell in our body needs glucose to sustain itself. Biotin also affects the synthesis of proteins by amino acids like keratin. Keratin is a vital component of hair, skin, and nails; 90% of hair comprises keratin. If keratin is not synthesised sufficiently, it affects hair growth and regrowth. So, when biotin is deficient, keratin production goes down, resulting in hair loss or alopecia, hair thinning.

There are various causes of biotin deficiency, including inadequate diet and genetic disorders that affect biotin metabolism, health conditions that affect the gut flora in producing biotin, certain medications, alcohol consumption, smoking, etc.

The amount of biotin we need per day varies with age. The table below indicates the recommended average daily requirement of biotin in micrograms

Recommended Biotin Intake:

  • Birth to 6 months – 5 mcg/day.
  • Infants (7-12 months) – 6 mcg/day.
  • Small Children (1-3 years) – 8 mcg/day.
  • Children (4-8 years) – 12 mcg/day.
  • Children (9-13 years) – 20 mcg/day.
  • Teens (14-18 years) – 25 mcg/day.
  • Adults (19+ years) – 30 mcg/day.
  • Pregnant teens and women – 30 mcg/day.
  • Breastfeeding teens and women – 35 mcg/day.

Benefits of Biotin:

Biotin helps the body carry out some important functions and keeps various systems in the body healthy, like the digestive system, nervous system, etc. Let us look at some key benefits of biotin in maintaining the health of our body:

1. Hair, Nail and Skin Health:

Biotin is linked to the development of hair, skin, and nails. It is vital for producing keratin, a protein that gives structure to hair, nails, and skin. Any deficiency in biotin results in hair loss, brittle, weak hair, thin hair, brittle nails, skin infections, skin rashes, etc.

2. Aids in Metabolism:

Biotin plays an important role in spearheading various metabolic processes that create energy. Various enzymes in our body require biotin to produce glucose from carbohydrates, fats, and amino acids. It also helps break down many vital amino acids to produce energy. It also plays a very important role in synthesising fatty acids.

3. Supports Pregnancy and Breastfeeding:

Pregnant and lactating women require higher energy levels, so nutrients get used up quicker than at other times. Biotin gets depleted more rapidly during these times. Low levels of biotin during pregnancy may lead to birth defects in unborn children. So consuming biotin-rich foods or supplements during these periods is very important.

4. Helps Manage Multiple Sclerosis:

Multiple sclerosis is an autoimmune disease where the protective covering of certain nerve fibres is damaged. This protective covering is made up of myelin, a lipid-rich component. Biotin helps in the production of myelin. Biotin consumption may help MS patients manage their disease better.

5. Helps in Diabetes Management:

Diabetes is a metabolic disease where the functionality of insulin is compromised, leading to higher levels of blood sugar levels. Some research says that people with diabetes have lower biotin levels, so biotin supplements for diabetic patients could help lower blood sugar levels.

6. Aids in Brain Functions:

Brain functionality depends on the conduction of nerve impulses. Myelin is the insulating layer around the nerves that facilitates the transmission of electric impulses and nerve cells. Biotin helps in myelin production, so depleted levels of biotin may affect cognition, memory, and other functionalities.

7. Protects Heart:

Biotin helps in defending against inflammation that affects heart health. It is also helpful in lowering the LDL or bad cholesterol levels that cause heart disease. It helps increase HDL or good cholesterol levels that benefit the body.

Foods That Are Rich in Biotin:

Biotin is water-soluble; hence, it is not retained in the body. Though the body does not synthesise biotin alone, gut bacteria produce biotin in levels that are usually sufficient for the body. Small amounts of biotin are also found in various food sources. Adequate intake of biotin-rich foods is always recommended, as biotin is a vital nutrient that can influence overall health. Let us look at some foods rich in biotin.

  • Egg yolk.
  • Yeast.
  • Cheese.
  • Nuts.
  • Whole grains.
