About

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. Biotin is often referred to as the 'beauty vitamin' and is recognised for its potential benefits for hair and skin. However, its functions extend far beyond cosmetic improvements.

What is biotin?

Biotin is part of the vitamin B complex and is necessary for the metabolism of carbohydrates, fats and proteins.

It acts as a coenzyme and facilitates various enzymatic reactions that are important for energy production and the synthesis of fatty acids.

What are the benefits from biotin?

There is a reason why biotin is called the beauty vitamin. Biotin is said to play a crucial role in maintaining healthy hair and skin. Additionally, biotin can help maintain the normal functioning of the nervous system and contribute to normal energy metabolism in the body.

Biotin can help to:

  • contribute to normal energy turnover
  • contribute to the normal functioning of the nervous system
  • contribute to normal metabolism of macronutrients
  • contribute to normal psychological functioning
  • help maintain normal hair
  • help maintain normal mucous membranes
  • help maintain normal skin

Biotin for hair

Biotin is important for the production of keratin, a protein that forms the structural basis of hair and skin. Adequate biotin levels ensure the proper synthesis of keratin, which can contribute to stronger, healthier hair. Additionally, biotin is said to help support healthy hair growth.

If you suspect that you are not getting adequate levels of biotin and feel that your hair could use a boost, it may be worth trying a dietary supplement such as 4HER Hair.

It is an advanced supplement for hair and nails, with over 20 active ingredients.

The role of biotin in mucosal health

When we think of biotin (vitamin B7), we often associate it with promoting healthy hair and skin. However, the benefits of biotin extend far beyond cosmetic improvements.

One of its lesser-known but equally important roles is that biotin can help support the health of the mucous membranes throughout the body.

Mucous membranes, also called mucosae, are thin, moist layers of tissue that cover various cavities and structures in the body, including the respiratory, digestive, urinary, and reproductive tracts.

Biotin is important for the maintenance of these mucous membranes and also supports the synthesis of fatty acids, which are essential components of cell membranes, including those of the mucosal cells.

Adequate biotin levels can ensure the normal function of mucous membranes, allowing them to effectively fulfill their protective role.

Many women in menopause and those over 50 often experience that their mucous membranes in the body feel dry. A common menopausal problem that many women experience is dry mucous membranes in the abdomen, but also problems with dry mouth or dry eyes. But the fact is that these problems can start both before the menopause and often worsen afterwards with increasing age.

If you feel that you have dry mucous membranes, it may be worth trying a food supplement with biotin:

4HER 50+ is for women over 50 who, among other things, experiencing problems with mucous membranes, bone health or energy.

Which foods contain biotin?

Biotin is naturally found in a variety of foods, including cooked eggs, nuts, seeds, whole grains, and some vegetables such as sweet potatoes and spinach.

It can also be obtained through dietary supplements, which are widely available in various forms such as biotin tablets and capsules. Additionally, certain bacteria in the gut can produce small amounts of biotin.

If you regularly use raw eggs in dishes such as mayonnaise, Caesar dressing, protein shakes, or egg toddies, this may affect your biotin levels: Raw eggs contain a protein called avidin, which can bind to biotin and inhibit its absorption. However, boiled eggs do not pose this problem because the avidin is inactivated during the heating process.

Can you get too little biotin?

Biotin deficiency is relatively uncommon in the Western world, as the vitamin is widely available in many foods and can also be produced by gut bacteria.

However, certain factors such as prolonged use of antibiotics, excessive alcohol consumption, or genetic disorders that impair metabolism can contribute to insufficient intake.

Can you get too much biotin?

High doses of biotin supplements can interfere with some laboratory tests, leading to inaccurate results. There are no documented side effects of overdosing and, as biotin is a water-soluble vitamin, the body can dispose of the excess itself, i.e. it is excreted in the urine.

Upper limit of daily intake

There is no complete information on what is a tolerable upper intake level (UL) for biotin, as there is limited evidence of adverse effects of high dietary intake. However, it is advisable to stick to recommended doses to avoid potential adverse effects.

Summary

While you can benefit from biotin for both hair and skin, the vitamin is beneficial for the whole body, from the inside out!

Biotin is found in many foods, and to naturally increase your intake of biotin, you should especially include legumes, cooked eggs and liver in your diet.
