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.

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 Menopause is for women who, among other things, are 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
• 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.

Can You Get Too Little Biotin?

Biotin deficiency is relatively uncommon in the Western world, as the vitamin is widely available in many foods.

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.

If you want to increase your biotin intake, you can also consider taking biotin (vitamin B7) supplements daily.
