| Typical dose | RDA for adults: approx. 2.4 µg per day; with confirmed deficiency, therapeutic doses are considerably higher — usually 1000 µg per day orally or intramuscular injections following a schedule set by a doctor | 200–400 mg of elemental magnesium per day (RDA: approx. 310–420 mg depending on sex and age) |
| Form | Cyanocobalamin or methylcobalamin orally; for deficiency related to absorption disorders — intramuscular injections that bypass the intestinal absorption step | Magnesium citrate, lactate or glycinate — better bioavailability than the oxide form |
| Average price | 10–30 zł za opakowanie starczające na kilka miesięcy suplementacji profilaktycznej | 20–45 zł za opakowanie 60 kapsułek (miesiąc stosowania) |
| Monthly cost | ok. 3–10 zł/miesiąc przy standardowych dawkach profilaktycznych | ok. 20–45 zł/miesiąc |
| Time to effects | Improvement in blood parameters (e.g. resolution of macrocytosis) is often visible after several to a dozen or so weeks of treatment, and subjective improvement in energy often comes sooner; neurological changes, if already established, may resolve more slowly or only partially, which is why early detection matters so much. | With an actual deficiency, improvements in well-being and sleep can be noticeable after 1–3 weeks; fully replenishing tissue stores takes longer, usually several weeks. |
| Who it's for | People on a vegan or vegetarian diet without regular supplementation | People with a diet low in leafy greens, nuts and whole grains |
