Measure, then drink
The range decides the tactics: deep deficiency requires therapeutic doses with control after 2–3 months, the norm requires support; overdose is real and toxic - “blog megadoses” without analysis are dangerous. Level D includes fertility checks (for both partners), osteoporosis and chronic fatigue.
When is it appointed?
- fatigue, hair loss, frequent illnesses - deficiencies;
- anemia - ferritin, B12, folate before treatment;
- pregnancy planning - folate, D, ferritin;
- vegetarianism, gastrointestinal diseases, metformin - B12 control;
- miscarriage, thrombosis - homocysteine.
Deficiencies are proven
Taking “vitamins just in case” is a lottery: deficiencies are measured, doses are selected based on numbers, and monitoring confirms replenishment. Ferritin - iron reserves (depleted long before anemia), D - hormone-like regulator with epidemic deficiency, B12/folate - hematopoiesis and nerves, homocysteine - an integral marker of the folate cycle and vascular risk. The exact number means the exact therapy.
