Introduction
Biotin, also known as vitamin B7 or vitamin H, is a water-soluble vitamin that plays a crucial role in various metabolic processes in the body. As part of the B-vitamin family, biotin is essential for the metabolism of carbohydrates, fats, and proteins. While it is often celebrated for its benefits to hair, skin, and nails, its functions extend far beyond aesthetics.
This article explores the importance of biotin, its dietary sources, health benefits, and recommendations for supplementation.
What is Biotin?
Biotin serves as a coenzyme that facilitates the conversion of nutrients into energy. It plays a vital role in the synthesis of fatty acids and glucose, making it crucial for energy production. Additionally, biotin is involved in regulating gene expression and contributes to maintaining the health of the nervous system.
Dietary Sources of Biotin
Biotin can be easily incorporated into a balanced diet through various food sources, including:
- Eggs: Particularly the yolk, which is rich in biotin.
- Nuts and Seeds: Almonds, walnuts, and sunflower seeds are excellent sources.
- Legumes: Beans and lentils provide significant amounts of biotin.
- Whole Grains: Oats and wheat germ are beneficial for biotin intake.
- Meat and Fish: Liver, pork, and salmon are particularly high in biotin.
- Dairy Products: Milk, cheese, and yogurt contribute to biotin levels.

Healthy Eating for the Mother During the Breastfeeding Stage
Adequate biotin levels are essential during pregnancy and breastfeeding, as they support fetal development and maternal health. Pregnant women may require higher amounts of biotin to meet the needs of both mother and baby.
Biotin Deficiency: Causes and Symptoms
Although biotin deficiency is rare, it can occur under specific circumstances, such as prolonged consumption of raw egg whites (which contain avidin, a protein that binds biotin) or in individuals with certain genetic disorders. Symptoms of deficiency may include:
- Hair loss
- Skin rashes
- Brittle nails

Supplementation and Recommendations
While biotin can be obtained through a balanced diet, some individuals may benefit from supplementation, especially if they have specific health concerns related to hair, skin, or nails. Biotin supplements are available in various forms, including tablets, capsules, and gummies.
The recommended daily intake of biotin varies by age and gender but generally ranges from 30 to 100 micrograms for adults. It is important to consult a healthcare professional before starting any supplementation, as excessive biotin intake can lead to potential side effects or interactions with medications.
