Vitamin D3 again

For UK people looking to measure 25(OH)D3 (and a few other parameters thrown in it seems) Sue sent this address

http://www.biolab.co.uk/vitamins.html

Very reasonable cost but you will need guarenteed next day delivery or a courier, and time the sample appropriately too.

Not sure how long it will be up.

Hi Joann,

You're very welcome.

Mark,

Anna over at Going Against the Grain emailed me a similar link, neither seem to work. I'd be interested to listen. Chris Masterjohn is clearly very clued up, though I can't quite bring myself to agree with LDL cholesterol causing IHD and obviously oxidised LDL and sdLDL are simply features of eating sugar. I'm old fashioned enough to feel that the sugar is one of a small number of causes of CHD...

Peter, re your sugar comment.

Is it glucose or fructose metabolism that is more relevant to CHD? Or is it a one-two punch with both implicated?

Peter said...

Hi Sam,

It's the fructose

Hi Peter,

Is this test much more useful from the "normal" test which doesn't distinguish between different forms of vitamin D?

Hi Jana,

That I don't know and as far as I can see "vitamin" D2 is a pharmaceutical which minimcs D3 but is chemically quite distinct, so there's no reason anyone should be taking it at all, certainly not taking megadoses....
