Om man ligger lågt på vitamin D2...

[AnnikaE]

...vilket tillskott ska man ta då? Kan D3 även hjälpa upp D2?

[Zepp]

Du kan alltid äta mer kantareller! 

 

"Vitamin D₂ kan endast fås via maten, och då främst från kantareller och några andra svampar och vissa alger."

http://sv.wikipedia.org/wiki/Vitamin_D

 

Det är altså D3 du skall sträva efter att få i dig!

[AnnikaE]

Danke! :-)

Hur i hela friden kan du veta att du har brist på vitamin D2?

 

Behöver man D2?

[AnnikaE]

Ingen aning. :-D

[MKJ]

Ingen aning. :-D

 

Frågan var ju hur du kunde veta att du har brist på D2. Har aldrig hört att något mätt det.

Hon kom väl på att hon åt väldigt lite kantareller, andra svampar samt alger?

Most 25(OH)D tests measure both D3 & D2 and it's the TOTAL of D2+ D3 that is reported as your vitammin d level.

Most people only have a little D2 and this may be below test accuracy threshold, in which case it isn't included in the total. 

 

It D3 Cholecalciferol, that is made in human skin and this is the form that works best in human bodies. D2 speeds up the rate the body disposes of Vitamin D so the more D2 you consume the faster your body catabolises ALL your vitamin D and the more you will need to increase vitamin D intake to keep up. 

 

 Ergocalciferol from mushrooms or supplements consumed with a standard meal increases 25-hydroxyergocalciferol but decreases 25-hydroxycholecalciferol in the serum of healthy adults.

 

Vitamin D4 in mushroom we don't know much about Vitamin D4 but it's half life is so short in humans it probably isn't significant.

Hörru Ted. Du läser ju uppenbarligen det vi skriver på svenska eftersom du kan svara så varför inte åtminstone sammanfatta ditt budskap på svenska också?

Som jag förstått det så översätter han till engelska med Google, och svarar sen på engelska, då han inte pratar svenska

Indeed I have the gibberish Google translate version of what you write so have to interpret this as best I can. 

Any jokes or humour or subtlety is totally lost in the Google translate so I presume that any summary of the evidence I provide in English would also be distorted so I prefer to limit my waffle to the minimum and present only the evidence I'm relying on, in the hope you are sufficiently intelligent to join up the dots.

The vitamin D made from UVB exposure of algae is cholecalciferal. Vitamin D3. So you can buy Vegan Cholecalciferal. (at a price) It's why Caribou grazing on lichen have Vitamin D rich meat. Slugs, snails also graze on lichen. Tthese are eaten by wild birds so game birds are also vitamin D rich. That's why the INUIT were able to survive the Winter by fermenting this and other meats in pits underground in seal oil for use in midwinter. They averaged 5000iu / day from their diet.

What do you mean by "at a price"? Do you mean that it is less absorbable or that it's expensive?

 

I buy the brand Vitashine, and they're not really expensive. 180 capsules á 5000IU for 30 euros.

Jag skrev väl "om man ligger lågt...." ;-) D2 stod på mitt provsvar men där fanns inget gränsvärde så jag har ingen aning om vilka nivåer man bör ha. Så frågan var mer hypotetisk än nåt annat.
