Better You vitamin D spray

For you to reach the recommended level from your current level, the Vit D Council suggests 3,700iu D3 daily, the nearest is 4,000iu.
BetterYou DLux 3000 (green packaging) gives 3,000iu D3 in 1 x spray
BetterYou DLux 1000 (light blue packaging) gives 1,000iu in 1 x spray
BetterYou DLux 1000 Vegan (dark blue packaging) gives 1,000iu in 1 x spray
BetterYou DLux+ Vitamin D+K2 (red packaging) gives 1,000iu in 1 spray
So the choice is yours. As K2 is an important cofactor needed when taking D3 then you might want to choose the red spray and take 4 x sprays daily. If you want to use a separate K2 then choose from the others, and take either 4 x sprays of either of the blue packages or lower your dose to 3,000iu daily and take 1 spray of the green.
Remember to retest in 3 months time as dose will possibly need adjusting as your level rises.
Just noticed that K2 is key to blood coagulation which may be an issue to me as I'm on blood thinners post bypass surgery. These conflicting requirements are driving me crazy!
It's K1 that aids blood clotting and K2 that directs calcium to bones, etc. However, as you have an issue this is something that you should research yourself thoroughly and make your decision based on that.
This is a post I did some time ago about this

although there is much more information out there that you will be able to find to help you make your decision.
A couple of links I've found linking K2 to interference with blood thinners. Of course I don't know how accurate or knowledgeable either of the comments are but enough to make me refrain from K2 supplementation until I get better information. Just to let you know the Vitaman D council link in your articles was dead for me.
"Q: Are there any medical conditions or medication that should not be used in conjunction with this supplement?
A: We do not recommend taking this if you are on any blood thinning medication."

" ...the MK-7 form of vitamin K2 has a longer half-life than K1, which may account for better stability of INR values (a clotting measurement) for people on anti-coagulant therapy. However, MK-7 has been shown to interfere with anti-coagulant therapy, and at much lower doses than vitamin K1..."

Yes, unfortunately the Vit D Council website is not live at the moment, possibly due to funding. However, that is a recent thing and my post I linked to was from 3 or more years ago.
You will probably find just as many articles saying that K2 is not recommended when on blood thinning medication as there are that say it's only K1 that you have to avoid. This is why it's so important to research thoroughly and decide which articles are from the most reputable sites. With such conflicting information it has to be your decision as to whether or not you take K2 and whether you risk the extra uptake of calcium aided by taking D3 being deposited in soft tissues and arteries, etc.
"With such conflicting information it has to be your decision as to whether or not you take K2."
Of course...but when I'm taking a, for this, but this makes me have to take b to counteract it, so I then need c because b suppresses d, which means I need e, but this needs f, but I can't have that because it stops a and g working. Aarrgghhhh!
For what it’s worth I’ve spoken to a couple of junior doctors in the family. The first, who gained a Masters in medical biochemistry before switching to become a doctor, says “Warfarin is a vitamin K antagonist” and “I would say that vitamin K has no effect on antiplatelets such as aspirin and clopidogrel”. The second says “I’ve never heard of it (K2) being contra-indicated for people on aspirin / clopidogrel”. You pay your money you make your choice, which is what I’ll do.
