Umuntu ojwayelekile ongenakho ukushoda kufanele athathe umthamo wansuku zonke okungenani wama-600 amayunithi wamazwe omhlaba (IU) ka-vitamin D, ngokusho Imithi Yale . Kodwa-ke, inani levithamini D umuntu okufanele alithathe lixhomeke ebudaleni bakhe, izimpawu zomuntu ngamunye, umlando wezokwelapha, kanye nempendulo ekuthatheni ivithamini.

Abantu abangaphezu kweminyaka engama-70 nabesifazane abaya esikhathini bangadinga ngaphezu kwe-600 IU. Njengoba abantu bekhula, isikhumba sabo sikhiqiza uvithamini D omncane, okusho ukuthi bazodinga ukwengezwa.

Abesifazane abakhulelwe nabantu abanezimo ezithile zezempilo eziphazamisa ukumuncwa kukavithamini D — njengesifo se-celiac noma i-cystic fibrosis - badinga ukudla okuphezulu nsuku zonke okungaphezu kwama-600 IU. Ungathatha uvithamini D nganoma yisiphi isikhathi sosuku. Noma kunjalo, kungakuhle kakhulu ukuwathatha ngamafutha athile okudla aqhamuka ekudleni okufana namantongomane noma imbewu ngoba kuncibilikile amafutha.



Abaningi odokotela futhi ochwepheshe bezempilo batusa ukuthatha imithamo emincane kavithamini D ngokuhamba kwesikhathi ukubuyisa amazinga. Kubantu abadala, lokhu kungasho ukudla okuphezulu kukavithamini D kwama-1,500-2,000 IUs. Ukweqiwa okuphezulu okusondele ku-10,000 IU kungadingeka kubantu abathile abane-osteoporosis noma ezinye izimo ezifanayo. Kodwa-ke, ukuthatha imithamo ephezulu kavithamini D (okungukuthi, i-40,000 IU) kungadala ubuthi bukavithamini D kanye nezinye izinkinga zempilo.

Uhlobo oluhle kakhulu lwevithamini D ongalusebenzisa njengesengezo yi-D3; noma kunjalo, i-D2 yamukelekile, kusho uTod Cooperman, MD, umsunguli we UmsebenzisiLab . I-D3 mancane amathuba okuthi ibangele amaphutha ekuhlolweni kwegazi, futhi amanani aphezulu angaphakamisa amazinga kangcono. Ngokuya kokwakhiwa, iziphuzo namaphilisi ngokuvamile akulungile (yize, sithole eminye imikhiqizo enganikeli amanani abhalwe kumalebula). Engikukhethayo kungamaconsi oketshezi, njengoba ungakwazi ukulungisa kalula umthamo. Futhi, ungayibeka ngqo ekudleni noma esiphuzweni, okufanele sikukhumbuze ukuthi uvithamini D, oncibilikiswa ngamafutha, kufanele athathwe nokudla okuqukethe amafutha ukwenza ngcono ukumuncwa.
