Biotin

What is Biotin?

Biotin, also known as vitamin B7, is a water-soluble vitamin that plays a crucial role in the body's metabolism. It is an important part of the B-vitamin complex and is known for its positive effects on hair, skin and nails. Biotin is also involved in the production of keratin, a protein that is a building block for hair and nails. Many use biotin as a dietary supplement to support beauty and health.

How does it work in the body?

Biotin acts as a cofactor for several enzymes involved in the metabolism of fatty acids, amino acids and glucose. By assisting in these processes, biotin contributes to energy production in the body. It is also important for maintaining a healthy metabolism and supporting nervous system function.

Scientific benefits

Several studies have examined biotin's effects on hair, skin and nails. A study published in the Journal of Cosmetic Dermatology showed that biotin can improve hair growth in individuals with biotin deficiency. Researchers have also found that biotin may help improve nail strength and reduce brittleness.

• Hair health: Research suggests biotin may help increase keratin production, resulting in thicker and stronger hair.
• Skin condition: Biotin has been shown to help improve skin moisture and elasticity.
• Nail strength: Studies have demonstrated that biotin can reduce nail brittleness and enhance overall nail health.

Dosage and recommendations

The recommended daily dose of biotin varies depending on age and sex. For adults, it is generally recommended to take between 30 to 100 micrograms per day. However, it is important to consult a doctor before starting supplements, especially if you have any underlying health conditions.

Best sources and forms

Biotin occurs naturally in a variety of foods. Some of the best sources include:

• Eggs (especially egg yolk)
• Nuts and seeds
• Legumes (such as beans and lentils)
• Whole grain products
• Dairy products (such as cheese and milk)

Biotin is also available as a dietary supplement, both as individual tablets and as part of B-complex preparations.

Side effects and warnings

Biotin is generally considered safe, and side effects are rare. Some individuals may experience mild side effects such as rash or gastrointestinal discomfort. It is important not to exceed the recommended dose of biotin, as this may lead to imbalances in the body. Always consult a healthcare provider before starting new supplements.
