Since 2012, we have been creating natural supplements in Ukraine, combining Tibetan medicine traditions with modern scientific technologies. Our Biotin (vitamin B7) 5000 mcg is one of the most popular products among customers who care about beauty and health. Over 14 years, we have sold tens of thousands of jars and collected hundreds of reviews about real improvements in hair, skin, and nail condition.
What is biotin and why is it called the “beauty vitamin”?
Biotin (vitamin B7 or vitamin H) is a water-soluble B vitamin that plays a key role in the metabolism of proteins, fats, and carbohydrates. It is essential for the synthesis of keratin — the main structural protein of hair, skin, and nails.
The body does not store large amounts of biotin, so it must be regularly obtained from food or supplements. Deficiency is rare, but modern lifestyle factors (stress, diets, antibiotics, smoking) quickly deplete reserves.
Science-backed benefits of biotin
💇 Hair health
Biotin participates in keratin production. Deficiency causes hair to become brittle, dull, and fall out. Studies show improvement in patients with confirmed deficiency.
💅 Strong nails
Clinical observations confirm: regular biotin intake reduces nail brittleness and splitting within 4–8 weeks of consistent use.
✨ Healthy skin
Supports the skin’s barrier function and reduces dryness and inflammation. Especially relevant for seborrheic dermatitis and dry skin.
⚡ Metabolism and energy
Biotin is a cofactor of carboxylases involved in energy production from nutrients. Without it, cells literally “starve” even with adequate nutrition.
⚠️ Important about scientific evidence (an honest approach):
Most studies (PubMed, 2017–2024) confirm the effectiveness of biotin specifically in cases of deficiency. In healthy people with normal vitamin levels, the effect on hair and nail growth is less pronounced. That’s why we always recommend testing your biotin levels first before taking high doses.

❓ FAQ — most common customer questions
Does biotin work for hair growth in healthy people?
Works best with hidden deficiency. In healthy people with normal biotin levels, the effect is moderate, but many customers notice improved hair quality, shine, and density within 6–8 weeks.
How long does it take to see results?
First changes (less hair loss, stronger nails) — within 4–8 weeks. Maximum effect — 3–6 months of regular use. Hair grows slowly, so patience is key to the result.
Can biotin be taken continuously?
Yes, since it is a water-soluble vitamin — excess is excreted from the body. We recommend taking it in courses: 3 months on + 1 month off. Then it can be repeated.
Does biotin cause acne?
In rare cases — yes. If rashes appear, reduce the dose or check other factors (hormones, nutrition, skin care). Usually, this is temporary and passes after adaptation.
Which dose is better: 5000 mcg or less?
5000 mcg is the optimal therapeutic dose for hair and nail issues. It is much higher than the daily recommended amount (30–50 mcg), but this dose is used in clinical studies and delivers visible results.
Can it be combined with other Tibetan Formula products?
Yes! Ideal combinations: Biotin + Collagen + Vitamin C (for maximum effect on skin and hair) or Biotin + Multivitamins for comprehensive body support.
Does biotin affect blood tests?
Yes — this is important to know! High doses of biotin can distort immunoassay results, including thyroid hormone tests (TSH, T3, T4) and troponin. Stop taking biotin 48–72 hours before testing and inform your doctor.
Conclusion
Biotin is not a magic pill but a science-backed tool for supporting beauty from within. Our Biotin (Vitamin B7) 5000 mcg / 90 capsules is designed for those who want real results: strong hair, healthy skin, and strong nails.
Remember: the best results come with confirmed deficiency and regular use for 3–6 months. If you have questions about choosing a course — contact us, we are always happy to help.
