Til alle regjeringer, helsemyndigheter og helsearbeidere, signert 197 fagfolk: – Så mye vitamin D trenger vi. Ytterligere forskning trengs ikke for å øke anbefalingen.
Oppropet av 7.12. er oversatt og forkortet av hemali. Du kan se det originale oppropet her.
En rekke artikler viser at vitamin D påvirker COVID-19 sterkere enn de fleste andre helsemessige forhold. Lave vitamin D-nivåer fremmer COVID-19-infeksjoner, sykehusinnleggelser og dødsfall. Derfor krever vi nå anbefalinger om økt inntak. D-vitamin påvirker tusenvis av gener og mange aspekter av immunforsvaret, både medfødte og adaptive. Det vitenskapelige grunnlaget viser at:
- Høyere vitamin D-blodnivåer er assosiert med lavere SARS-CoV-2-infeksjon.
- Høyere vitamin D-nivåer er assosiert med lavere risiko for alvorlig forløp av sykdom (innleggelse, pustehjelp, død).
- Intervensjonsstudier (inkludert randomiserte, placebokontrollerte) indikerer at vitamin D kan være effektiv behandling.
- Mange artikler viser flere biologiske mekanismer der vitamin D påvirker COVID-19.
- Hills vitenskapelige kriterier for årsak, intervensjonsstudiene og biologiske mekanismer indikerer at vitamin Ds innflytelse på COVID-19 er årsakssammenheng, ikke korrelasjon.
- (Altså forskjellen mellom at faktorer tilfeldigvis inntreffer samtidig, og at de forårsaker hverandre)
De fleste mangler vitamin D
Betydningen av vitamin D er kjent, men de færreste får nok. To vanlige definisjoner av mangel er
<20ng / ml (50nmol / L), målet for de fleste helsemyndigheter
<30ng / ml (75nmol / L), målet for flere medisinske samfunn og eksperter
Mange har nivåer under disse målene. De fleste anslag for mangel <30 ng / ml viser at godt over halvparten av oss har nivåer under dette. Blant mange grupper er tallet mye høyere. Nordiske anbefalinger for daglig inntak er 10 µg/ for dem under 75 år. For dem over er anbefalingen 20 µg/daglig.
-Annonse-
Risikoen for mangel oppveier enhver annen risiko knyttet til for mye vitamin D. 197 internasjonale fagfolk.
Vitamin D-mangel er vanligere om vinteren, og noen grupper er særlig utsatt:
- overvektige
- mørkhudede
- beboere på sykehjem ol.
- disse samme gruppene har økt risiko for COVID-19
For 97,5 prosent av oss kreves:
- 3875 IE (97mcg) daglig for å nå 20ng /ml.
- 6200 IE (155mcg) for å nå 30ng /ml.
Altså fire ganger høyere inntak enn de typiske, nasjonale retningslinjer. Flere oppfordringer fra fagfolk om å øke offisielle anbefalinger ga ikke resultat innen SARS CoV-2 kom. Forskning antyder at COVID-19-pandemien opprettholdes via infeksjon hos dem med lite vitamin D. Og at død oftere inntreffer hos dem med mangel enn uten.
Tryggere enn steroider som behandling
Tiår med data viser at D-vitamin har svært lav risiko: Forgiftning er ekstremt sjelden med nevnte anbefalinger. Risikoen for mangel oppveier enhver annen risiko knyttet til for mye vitamin D. D-vitamin er mye tryggere enn steroider, den vanligste behandlingen ved COVID-19. Vi trenger ikke å vente på ytterligere kliniske studier for å øke bruken av noe så trygt.
Derfor ber vi regjeringer, leger og helsearbeidere om å straks anbefale og iverksette tiltak for befolkning for å øke inntaket av vitamin D:
- Vitamin D fra alle kilder som er tilstrekkelige til å oppnå 25 (OH) D-serumnivåer over 30 ng /ml (75 nmol/l). Det reduserer risiko for COVID-19.
- Anbefaling til voksne: inntak 4000 IE (100 mcg) daglig (eller minst 2000 IE)
- Voksne i risikogrupper kan trenge høyere inntak.
Mange faktorer disponerer for høyere risiko for SARS-CoV-2: alder, kjønn, underliggende sykdommer mm. Men nok vitamin D er uten tvil det tryggeste, enkleste, billigste og mest effektive tiltaket for å redusere risiko for å bli smittet av og for alvorlig forløp ved COVID-19.
