Taking vitamin D3 and K2 separately

I’ve got a bottle of D3 3000IU and K2 Menaquinone MK7 200ug.

I’ve read on here to take them separately at different times of the day.

Well after being ill with some sort of virus from the Sunday before Christmas until the Sunday after New Year, I broke my right arm - I’m only right handed! - on Wednesday night so I can type with the iPad dictation facility but trawling through posts is very hard work.

If anyone who knows could be bothered letting me know what’s already been said, probably multiple times, I’d be really grateful.

Thanks.

Are your D3 and K2 in softgel form, liquid, oral spray, tablets or capsules?

Both vitamins are fat soluble so need fat to be absorbed.

If they are oil based, this would usually be softgels and liquid, then they could be taken at the same time but also have some kind of dietary fat with them, eg fattiest meal of the day, full fat yogurt, cheese, toast and butter, etc, to make sure there is enough fat for both of them.

Tablets and capsules don't contain any fat so would need dietary fat to aid absorption and are best taken at opposite ends of the day with some form dietary fat, maybe take one with breakfast and one with evening meal.

If they are in oral spray form then they are absorbed through the mucous membranes in the oral cavity so no need to worry about when you take them but I wouldn't take one immediately after the other.

Thanks for that, the K2 are tablets and the D3 are capsules. Good excuse to have something fatty.

I have just read exactly the same thing, K2 away from D3 and magnesium away from both if you also supplement. Apparently they contest each other for absorption. I also did not know this until recently as I was taking them all together !!!!!

The ones I’m taking at present are D3 and K2 combined- that can’t be the ideal arrangement can it?

Well companies produce and market multi vitamins and that certainly can't be ok as we are well aware of. One wonders just what body of knowledge is advising them? My source of info comes from Jayson Calton who has a PhD in nutrition and has several published books on nutrition. Apparently he is one of the world's leading experts in micro-nutrients and dietary supplement science.

Strange isn’t it. I don’t ever take multivitamins and for some reason - well because I know you should take both K2 with D3 - I trusted that a D3/K2 combo would be ok. Silly me.
