Andriy Duyko — founder and ideologist of the "Tibetan Formula Duyko" brand.
Since 2012, we have been creating natural supplements in Ukraine, combining the traditions of Tibetan medicine with modern scientific technologies. Our B vitamin complex is one of the basic products for supporting energy, the nervous system, and overall well-being. Over many years, we have received thousands of customer reviews noting reduced fatigue, improved mood, and increased stress resilience.
What are B vitamins and why are they so important?
B vitamins are 8 water-soluble vitamins (B1, B2, B3, B5, B6, B7, B9, B12) that work as a team. They are key cofactors in energy metabolism, nervous system function, neurotransmitter production, and red blood cell formation.
Unlike fat-soluble vitamins, they hardly accumulate in the body, so they need to be obtained daily. The modern lifestyle (stress, coffee, alcohol, diets, antibiotics) quickly depletes B vitamin stores.
Main functions of the B vitamin complex
- Energy and fatigue reduction — help convert food into ATP (cellular energy). B1, B2, B3, B5 are especially important.
- Nervous system health — support the myelin sheath of nerves, synthesis of serotonin, dopamine, and GABA. B6, B9, and B12 are especially important for the brain and mood.
- Stress and emotional balance — reduce cortisol levels, help with anxiety, irritability, and "brain fog."
- Healthy skin, hair, and nails — B7 (biotin) and B5 participate in keratin synthesis.
- Cardiovascular system — lowers homocysteine levels (along with B6, B9, B12).
Scientific evidence (E-E-A-T)
Studies confirm that taking a B vitamin complex improves energy metabolism, cognitive functions, reduces stress symptoms, and supports peripheral nerve regeneration. The effect is especially noticeable with subclinical deficiency, which often occurs even with a normal diet.

FAQ — most common customer questions
1. Can B vitamins be taken continuously?
Yes, but it’s better to take it in courses with short breaks. The body excretes the excess through urine.
2. When will the effect appear?
Many customers feel a surge of energy and mood improvement within 1–2 weeks. The maximum effect occurs after 4–8 weeks.
3. Does the B complex help with stress and anxiety?
Yes, especially B6, B9, and B12 participate in the synthesis of “happiness hormones.” Studies show a reduction in stress symptoms.
4. Can it be combined with Biotin?
Perfect! Biotin (B7) is part of the B group, but in a separate high dose, it works better for hair, skin, and nails.
5. Is it suitable for vegetarians?
Yes. Especially important for those who do not eat meat, as the risk of B12 deficiency is higher.
6. What is the difference between individual B vitamins and the complex?
The complex provides a synergistic effect — vitamins work better together. For example, Vitamin B1 and Vitamin B6 individually have a narrower effect, while the complex covers all 8 vitamins simultaneously.
Conclusion
B Vitamin Complex is the fundamental support for energy, nerves, and emotional balance in today’s world. Our product is designed for those who want to feel energetic, calm, and productive every day.
