  Hello and welcome to the Blueness Guide, the ideal nutrition guide for humans. Today, we're going to take a look at vitamin B8, also known as vitamin B7 by English speakers. It's a water-soluble vitamin, which means it's eliminated through urine and isn't stored by the body. It is essential for ourselves because it supports a number of reactions necessary for the absorption of proteins, carbohydrates, and fats. It's especially known for its role in sugar production by the liver. So it's highly recommended to adopt a healthy, balanced diet to meet your body's daily needs. It belongs to the large family of B vitamins. It is essential for our metabolism, and its self-production by the body has not yet been fully proven. So it's a water-soluble vitamin, as we've said. And so it is quickly eliminated from the body through urine. It's known in eight different forms. But biotin... its naturally occurring form is the active form recognized to this day. When it is absorbed by the body, vitamin B8 directly becomes part of the structure of a coenzyme that is essential for the activity of a number of enzymes. It is especially involved in the metabolism of proteins and certain amino acids, as well as the metabolism of carbohydrates and lipids. Finally, it ensures the proper functioning of the nervous system as well as the renewal of skin and hair cells. Frequently included in dietary supplements for nails, skin, and hair, the effectiveness and beauty benefits of this vitamin are often highlighted. However, as of now, these claims remain at the stage of scientific studies. Nevertheless, a deficiency in vitamin B8 is most noticeable on the skin and hair. In fact, these are two conditions that are often treated with biotin supplements, which is another name for vitamin B8. So what are our needs? The recommended daily intake is 50 micrograms for a young adult or teenager, a pregnant woman or an adult. So 50 micrograms per day. The needs of a breastfeeding woman can go up to 55 micrograms. These needs are generally met by a healthy balanced diet. By the way, vitamin B8 is found in almost all foods, but in greater amounts in legumes, organ meats, meat, and in nuts. Vitamin B8 deficiency is rarely observed. The main signs are seen in the skin, so there's inflammation, as well as in the mucous membranes and nerves, which can lead to hallucinations, drowsiness, and mood disorders. Simply administering vitamin B8 is often enough to correct this type of deficiency. Moreover, no safety limit has been set for this vitamin so far, because the risk of overdose is relatively minimal. It's worth noting, however, that consuming large amounts of raw eggs can prevent the absorption of vitamin B8. Similarly, prolonged antibiotic treatment also reduces its absorption. That's all for vitamin B8
