$Approach: conceptual metaphor. Palette: D, bold color field. A single cracked ceramic-white bone-shaped column, like a femur section, stands upright at the center of a saturated mustard-yellow seamless backdrop. A thin, clean hairline fracture runs through its middle. Beside it, a small golden-amber glass dropper bottle sits tipped, with one droplet suspended just above the bone and not touching it, which suggests extra vitamin D that makes no difference. The camera is at a low three-quarter angle with a shallow depth of field. Hard, directional studio light from the upper left casts a crisp, long shadow across the yellow floor.

Visokodozirani vitamin D za kosti? Petogodišnje ispitivanje kaže ne

Uzimate dodatni vitamin D da biste ojačali kosti? Petogodišnja randomizovana studija na 2.495 starijih Finaca pokazala je da ni doze od 1.600 ni 3.200 IU dnevno nisu smanjile broj preloma u odnosu na placebo. Čudno, grupa koja je prima 1.600 IU imala je čak i više preloma (HR 1,52), dok viša doza takav efekat nije pokazala – što ukazuje na moguću slučajnost. Učesnici su već na početku imali dovoljno vitamina D, pa rezultati možda ne važe za osobe s deficitom. Evo šta je studija otkrila, koja su njena ograničenja i šta razmotriti pre nego što kupite još jednu bočicu.
