Uthini Umahluko phakathi kweVithamin D2 kunye neD3? Yeyiphi Esebenzayo?

I-Vitamin D yintsapho yezondlo ezinokufana kwisakhiwo sekhemikhali. IiVithamini D2 kunye ne-D3 zifumaneka ekutyeni. Zombini ezi ntlobo zinceda ukuhlangabezana neemfuno ze-vitamin D. Kukho umahluko obalulekileyo phakathi kwabo. “Umahluko phakathi kwe-vitamin D2 kunye ne-D3 ngoba?"

Umahluko phakathi kwe-vitamin D2 kunye ne-D3

Uphononongo lubonisa ukuba i-vitamin D2 ayisebenzi kangako ekunyuseni amanqanaba egazi kune-vitamin D3.

Ivithamin Dzineendlela ezimbini eziphambili:

Vitamin D2 (ergocalciferol)
Ivithamin D3 (cholecalciferol)

Umahluko phakathi kwe-vitamin D2 kunye ne-D3 imi ngolu hlobo lulandelayo;

I-Vitamin D3 ivela kwizilwanyana kwaye i-vitamin D2 ivela kwizityalo.

Iintlobo ezimbini zevithamini D ziyahluka ngemithombo yokutya. I-Vitamin D3 ifumaneka kuphela kukutya okuvela kwizilwanyana, ngelixa i-vitamin D2 ifumaneka kakhulu kwimithombo yezityalo kunye nokutya okuqinisiweyo.

Imithombo ye-vitamin D3 ibandakanya;

Iintlanzi ezinamafutha kunye neoli yeentlanzi
Isibindi
Umpakathi weqanda
ibhotolo
Izongezo zesondlo

Imithombo ye-Vitamin D2 yile ilandelayo;

Amakhowa (akhule kwisibane seUV)
Ukutya okuqinisiweyo
Izongezo zesondlo

Ngenxa yokuba ivithamin D2 inexabiso eliphantsi ukuvelisa, le yeyona ndlela ixhaphakileyo efumaneka ekutyeni okuqinisiweyo.

I-Vitamin D3 yenziwa esikhumbeni

Ulusu lwethu luvelisa i-vitamin D3 xa luvezwe kukukhanya kwelanga. Ngokukodwa, imitha ye-ultraviolet B (UVB) evela ekukhanyeni kwelanga ibangela ukwakheka kwe-vitamin D7 kwi-compound 3-dehydrocholesterol esikhumbeni.

Inkqubo efanayo yenzeke kwizityalo kunye nefungi, apho ukukhanya kwe-UVB kubangela ukubunjwa kwe-vitamin D2 kwi-ergosterol, i-compound efumaneka kwi-oyile yezityalo.

Ukuba uchitha ixesha ngaphandle ngeveki, ngaphandle kwe-sunscreen, unokuvelisa yonke i-vitamin D oyifunayo.

IiNzuzo zeOyile yeCoconut-Ubungozi kunye nokusetyenziswa

Kodwa qaphela malunga nokuchitha ixesha elininzi elangeni ngaphandle kwe-sunscreen. Oku kubaluleke ngakumbi kwabo banolusu olulungileyo. Ukutshiswa lilanga ngumngcipheko obalulekileyo womhlaza wolusu.

Ngokungafaniyo ne-vitamin D ethathwe kunye nezongezelelo zesondlo, awuyi kuba ne-overdose ene-vitamin D3 eveliswe eluswini. Kuba ukuba umzimba sele unokwaneleyo kuwo, ulusu luvelisa ngaphantsi.

I-Vitamin D3 isebenza ngakumbi

IiVithamini D2 kunye ne-D3 azifani xa kuziwa ekukhuliseni amanqanaba e-vitamin D. Zombini zifunxwa ngempumelelo egazini. Nangona kunjalo, isibindi siyawatshintsha ngokwahlukileyo.

Isibindi sidibanisa i-vitamin D2 kwi-25-hydroxyvitamin D2 kunye ne-vitamin D3 kwi-25-hydroxyvitamin D3. Ezi khompawundi zimbini zaziwa ngokudibeneyo njenge calcifediol.

I-Calcifediol yeyona ndlela ijikelezayo yevithamin D, kwaye amanqanaba egazi abonisa iindawo ezigcina umzimba ezi zondlo.

I-Vitamin D2 ivelisa i-calcifediol encinci kunexabiso elilinganayo le-vitamin D3. Uninzi lwezifundo zibonisa ukuba i-vitamin D3 isebenza ngakumbi kune-vitamin D2 ekunyuseni amanqanaba egazi le-calcifediol.

Ukuba uthatha isongezelelo se-vitamin D, unokuthatha i-vitamin D3.

Iingcali zenzululwazi ziye zavakalisa inkxalabo yokuba izongezo ze-vitamin D2 zinokuba kumgangatho ophantsi kunezongezelelo ze-D3.

Ngapha koko, uphononongo lubonisa ukuba ivithamin D2 ichaphazeleka kakhulu kukuguquguquka kokufuma kunye nobushushu. Kungenxa yoko le nto izongezelelo ze-vitamin D2 zinokuthi zithobe ngokuhamba kwexesha.
