Vitamin Deficiency — Myth or Reality?

Vitamin Deficiency — Myth or Reality?

There is a lot of discussion around vitamins today: some believe deficiencies are rare, while others think almost everyone has them. The truth lies in between. Vitamin levels truly affect immunity, energy, skin, brain function, and metabolism — but the only reliable way to assess them is through lab tests.

Why does deficiency occur?

• poor or unbalanced diet
• chronic stress
• lack of sunlight
• digestive disorders
• pregnancy or breastfeeding
• intense physical activity

Which symptoms may indicate deficiency?

• fatigue, low energy
• brittle nails, hair loss
• irritability, mood swings
• muscle weakness
• frequent infections

How to know for sure?

Only blood tests (vitamin D, B12, folate, iron, etc.) can show the real status.

Conclusion: vitamin deficiency is real, but highly individual. Taking supplements without testing can be harmful — proper diagnostics and medical guidance are essential.
