Hi, I want to buy a vitamin D supplement for the 3 months where the weather is too cold to sit for 15 minutes to get sun outside. I've seen that many vitamin D supplements come with vitamin K too (vitamin K2 mk7 they say its the best)
Anyway, I just don't understand why is this the case. I've never tested my vitamin K in a lab, but if you had a defecit wouldn't it be obvious?
Isn't there an higher chance you are overdosing by taking a supplement than not taking it? I have tested for vit D and it was low, but wouldn't low levels of vit K give you horrible obvious sides?
Which markers would be needed in a lab to test for vitamin K anyway? For vit D I tested both OH25 and 1,25 metabolites and both came back on the lower end.
I just don't want to take a vitamin that I may not even need and do more harm than good (I only supplement stuff if I get a bloodwork first but I wasn't sure what to get to accurately measure vit K)
