Biotin was originally called vitamin H, because it was recognized early on its importance for skin and hair. Like folic acid, biotin belongs to the vitamin B complex and is known as vitamin B7. Biotin is water-soluble and can be bound by the proteins streptavidin and avidin. Both for the metabolism of fat and the metabolism of carbohydrates and proteins, as well as in the nucleus biotin plays an important role. It is also involved in the regulation of blood sugar levels. As a dietary supplement, biotin has experienced a veritable boom in recent years: biotin capsules and biotin tablets are said to provide beautiful hair, strengthen nails and counteract inflammatory skin reactions such as acne.

Biotin deficiency is rare

Biotin is essential for important processes of the body. Unlike other vital vitamins, the body usually absorbs enough biotin through certain foods. Therefore, healthy people who eat a balanced diet rarely suffer from biotin deficiency. Possible symptoms of biotin deficiency may be:

  • Hair: Hair loss, dull and brittle hair, color changes of the hair
  • Skin: Skin disorders and lesions, local paraesthesia, pale and greyish skin color
  • Brittle nails
  • Higher susceptibility to infections
  • Muscle aches
  • depression
  • Increased cholesterol levels
  • Loss of appetite and nausea
  • hallucinations
  • Changes in the metabolism
  • movement disorders
  • Disorders of cardiac function

Biotin in food

Some foods are true biotin dispensers: dry yeast, beef liver, egg yolks, soybeans, oatmeal, walnuts, mushrooms, wild rice, fish and spinach; Bananas and tomatoes, milk and kidneys also supply the organism with biotin.

However, anyone who has a biotin deficiency can not remedy this by eating certain foods, but has to resort to biotin capsules or biotin tablets. Smokers, alcoholics, nursing mothers and people who suffer from certain hereditary diseases (such as biotinidase deficiency) or over-consumption of raw eggs are susceptible to biotin deficiency. The long-term use of antibiotics can also lead to a biotin deficiency.

Biotin: hair, skin and nails

More and more women are using biotin capsules and biotin tablets as supplements to positively influence the structure and growth of their skin, hair and nails. Biotin has its greatest effect on the hair. It can help if the hair becomes thinner, brittle and dull. Biotin can also act against hair loss - biotin deficiency, however, is not only noticeable by hair loss on the head, even the smallest hair such as eyelashes and eyebrows can go out.

If you want to specifically improve the look of your hair with biotin, you can even purchase shampoo with biotin in some specialist shops. However, the body hardly absorbs biotin through the skin, so definitive efficacy can not be confirmed.

Biotin capsules and biotin tablets

If you are looking for a wellness all-in package from the inside, you will most likely find biotin tablets and biotin capsules in the drugstore, health food store or pharmacy that contain additional active ingredients. The trace element zinc provides the skin with moisture, strengthens the nails and prevents hair loss.

Silica is also commonly found in biotin capsules and biotin tablets. The term silica describes various sediments and minerals that have a high silicon content. However, recent studies give rise to caution when dealing with silica: Scientists suspect a connection between the intake of silica over a long period of time and possible kidney damage. Likewise, a possible health risk from oral intake of silica is not excluded, since many preparations are largely composed of cristobalite and quartz and could possibly cause silicosis.

Zinc and biotin for beautiful hair

Due to the risks mentioned above, a permanent ingestion or overdose of silica biotin capsules or tablets should be foreseen. For beautiful hair, therefore, rather recommend products with a mixture of biotin and zinc. Like biotin, zinc is also involved in the metabolism and promotes cell growth. In addition, zinc increases the ability to concentrate, is important for the immune system and the body's defense and it is essential for the function of many hormones.

By the way, it is not just "vain" women who appreciate the effect of biotin on hair, skin and nails. Pet owners also give biotin pills to their four-legged pets, such as when man's best friend has broken claws, a dull coat and flaky, leathery skin. An older dog should also be able to be saved from impending hair loss. In addition to biotin for dogs, the animal feed industry has developed products for another animal, which benefits from the additional feeding with the vitamin: Biotin provides the horse for healthy, strong hooves - which causes a better hold of the iron - and strengthens the skin and hair during the coat change,
