| Form | Cyanocobalamin or methylcobalamin orally; for deficiency related to absorption disorders — intramuscular injections that bypass the intestinal absorption step | Creatine monohydrate (the best-studied form) |
| Average price | 10–30 zł za opakowanie starczające na kilka miesięcy suplementacji profilaktycznej | 40–70 zł za 500 g monohydratu (ok. 100 porcji po 5 g) |
| Monthly cost | ok. 3–10 zł/miesiąc przy standardowych dawkach profilaktycznych | ok. 15–25 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. | First strength effects after 1–2 weeks; full muscle saturation and maximum effect after about 3–4 weeks of regular use. |
| Who it's for | People on a vegan or vegetarian diet without regular supplementation | People doing resistance training and high-intensity sports |
