There are dosages ranging from 100mcg to 5mg and I think I saw 15mg once.

 

Does taking 5mg a day have any issues?

The probably highest dose which is available as supplement is from http://www.k-vitamins.com/ at 30.5 mg per cap. If you read the research at that site you'll for example also find references for cases where up to 400 mg where used (as antidote to overdoses of vitamin K antagonists).

 

However, I do find web accounts of side-effects of all and more harmless vitamins at tiny doses, and even from dietary sources, which are really difficult for me to believe - vitamins are essential substances impossible to live without, after all - which makes me think they are often from other ingredients (like binder and filler in pill or capsules) or other unexplainable individual intolerances.

Therefore you'll find people who say they had issues with even less than that, for any supplemental substance available.

 

But nobody could say how you would react to any supplement or food taken or at what amount, or have any issue. And it is therefore the best to start any supplement at its smallest possible dose (when necessary by taking even only fractions of a cap) and increase gradually over weeks, months and years. If one brand gives you a reaction, you could still try different brands.

It’s pointless to guess unless you get blood work done. I think 100mcg with a meal containing fat is a perfectly normal dose if you absorb it normally. But the only way you will know it’s from a blood test. I don’t believe there is a Vitamin k2 test though I’ve only seen K1 and typically they don’t even test that they usually do a coagulation test.

So really I have been taking 5mg because I have had issues with hypercalcemia from D supplementation, and I read that K2 is useful for teeth.

I'm fighting the same issue. I need vitamin D for my brain fog but the calcium ends up being a problem. Massive K doses aren't helping but I did try lowering the amount of D and dosing magnesium malate heavily just today. This may work...will get back to you.

First step would certainly to identify those dietary sources which provide the most calcium and eliminate them.

Yep. Is magnesium effective against calcium?

Not in my case: Vitamin D3 raised calcium from deficient to normal, but depleted magnesium in that process to very severely deficient (despite supplementing about 700 mgs Mg). Therefore I increased up to 2.5 g/d of oral elemental supplemented Mg during the last 10 years (about 1.6 in average). But only Mg-sulfate IVs since last November last year ceased painful-muscle cramps completely. While calcium remained in the mean of normal despite all that supplemented Mg.

It could be different for you.

I had a good start on magnesium. No cramps and no dehydration I get when my calcium seems to be out of control. Wish I knew more about how calcium and magnesium interact -any idea?
