The 21st Century calcium‑500 + D3 tablets share a uniform formulation: vitamin D3 at a standard 15 µg dose, a tablet matrix of maltodextrin, croscarmellose sodium, magnesium silicate, magnesium stearate, polyethylene glycol, polyvinyl alcohol and stearic acid, with all ingredient amounts disclosed. This combination sets it apart by featuring magnesium silicate and polyvinyl alcohol, both relatively rare in competing calcium‑D3 supplements. While the core composition is identical, individual flavours may vary slightly in non‑active additives, and pack‑size pricing differs, with bigger packs generally offering better value.
