Beautiful, silky skin and thick, shiny hair need Biotin. That’s why Biotin is often referred to as the beauty vitamin. Biotin may do more for your beauty than the most promising cosmetic products in the world.
The name “bios” means life — and Biotin (also known as Vitamin H or B7) is a life-sustaining vitamin that plays a vital role in nearly all key metabolic processes.
Without Biotin, the body cannot generate energy from carbohydrates and fats. It also nourishes the skin, hair, and nervous system.
A deficiency may not only affect skin and hair but also show up in the form of low energy. Biotin is especially important during pregnancy and breastfeeding, supporting the optimal development of the baby.
There are 8 different forms of Biotin, but only D-Biotin is the natural form found in food — and the only one with full vitamin activity. Always choose Biotin supplements that only contain D-Biotin.
To benefit fully from Biotin, proper dosage matters — and this depends on age, sex, and individual needs (e.g. absorption issues).
A high-dose supplement with 5,000 mcg (5 mg) is recommended for Biotin treatment courses or for people with increased needs.
While a minimum of 2,000 mcg is considered effective, do not exceed 10,000 mcg per day to avoid side effects.
As a natural vitamin, Biotin is generally well tolerated. Side effects are rare as long as daily intake stays below 10 mg (10,000 mcg).
However, some Biotin tablets contain unnecessary additives, preservatives, dyes, and fillers, which can impair tolerance.
Biotin is available as both tablets and capsules. Both are effective, but experts recommend capsules as they are easier to swallow, gentler on the stomach, and ensure optimal absorption.
Additives in Biotin tablets can reduce absorption. That’s why capsules are preferred — they help the body absorb Biotin more efficiently and improve its effectiveness.
The best Biotin supplements are free from unnecessary additives to avoid allergies and side effects. This is especially important since Biotin should be taken for at least 6 months to achieve full beauty benefits.
Biotin, also known as Vitamin H or B7, is a water-soluble B-vitamin known for its positive effects on hair, skin, and nails. Since the body cannot produce Biotin on its own, it must be consumed through food — although some is also produced by gut bacteria.
Biotin is essential for fat, carbohydrate, and protein metabolism and supports the growth and longevity of blood cells, skin cells, and nerve tissue.
It also plays a key role in Keratin production, which is important for strong nails and healthy hair.
In Switzerland, Biotin is even used as a therapeutic drug to treat nail and hair growth disorders as well as seborrheic dermatitis in infants.
While Biotin is found in many foods, its absorption can be blocked by avidin, a substance in raw egg whites.
Since Biotin is water-soluble, it can be lost during washing or cooking of food.
Biotin is found in a wide range of foods. In plant-based foods, it's present in free form. In animal-based foods, it is bound to proteins and is released during digestion.
Best natural sources of Biotin include:
Important: Raw egg whites contain avidin, which binds to Biotin and prevents absorption. Avoid consuming raw eggs frequently to prevent deficiency.
Tip: Be especially mindful of your Biotin intake if you consume a lot of sugar, drink alcohol regularly, or take antibiotics — as these factors can compromise your gut flora and reduce Biotin production.
To prevent a deficiency, Biotin can be taken as a supplement in capsule or tablet form. The German Nutrition Society recommends 30–60 mcg per day to maintain health.
However, micronutrient experts recommend 2,000 to 5,000 mcg daily over several months to improve skin, hair, and nails.
When choosing dietary supplements, quality and safety matter. At VitaminExpress, you’ll find only premium-quality Biotin supplements that are pure, free from unnecessary additives, and non-GMO.

Biotin, also called vitamin B7, is a water-soluble vitamin and part of the vitamin B complex. The B vitamins are required in particular for the function of the metabolism, the nerves, the digestion and for the heart / circulation.
Biotin acts like a coenzyme in the body and is required for the metabolism of fatty acids, amino acids and glucose. This means that if we eat foods that contain fats, proteins and carbohydrates, biotin must be present to convert these macronutrients so that they can be used for body energy, physical activities and for brain functions.
Biotin is also a nutrient that helps to stay young and attractive as it plays an essential role in maintaining beautiful, healthy hair, nails and skin. Biotin is also sometimes called vitamin H, which is derived from hair and skin.
Biotin is also found in many hair and beauty care products, although it is believed that it is not very well absorbedthrough the skin and must actually be taken orally to profit from all of its benefits.
Biotin is water-soluble, which means that it flows in the bloodstream and any excess or unused amounts are excreted in the urine. The body therefore does not build up any biotin reserves. However, this also means that one should ideally take biotin daily to ensure the adequate intake in the body.
Some of the people who are at increased risk of biotin deficiency are:
Biotin deficiency can manifest itself through symptoms such as:
To avoid a deficiency, the DGE (German Society for Nutrition) recommends the following daily intake:
Biotin mostly occurs as part of B-complex food supplements. These usually include a full range of B vitamins, including vitamins B1, B6, B12, B2 and B3 (niacin). Together, the B-vitamin complexes support metabolic activity,brain functions, nerve signals and many other important daily functions. They also work together, so it's always best to take B vitamins together to make sure they get the best results.
