The real difference
MK-7 is the menaquinone form of vitamin K2 with a half-life measured in days rather than hours, which is why it is dosed once daily while MK-4 needs repeat dosing. Both of these are MK-7 at 100 mcg, so the form and the dose are the same.
Neither carries an independent certification, which makes the comparison unusually simple: the same nutrient, the same dose, no verification difference, and a meaningful gap in cost per day. The remaining differences are capsule versus softgel and servings per bottle.
Who each one is for
Choose on cost with the same form, same dose and no certification on either side, the lower cost per day is the rational pick.
If you take a blood thinner vitamin K interacts directly with warfarin. Do not start either product without talking to whoever manages your anticoagulation.
Pairing with vitamin D K2 is commonly taken alongside vitamin D. If you would rather buy them together, see vitamin D with or without K2.

Frequently asked questions
Is NOW Foods or Nutricost vitamin K2 better?
Both deliver 100 mcg of MK-7 and neither carries a third-party certification, so the nutrient, the dose and the verification level are the same. The decision is cost per day and whether you prefer a capsule or a softgel.
Is MK-7 better than MK-4?
MK-7 has a much longer half-life, which is why it works as a once-daily dose while MK-4 is typically taken several times a day to maintain levels. Both products here are MK-7.
Can I take vitamin K2 with a blood thinner?
Not without medical supervision. Vitamin K directly opposes warfarin, and changing your K intake changes how much anticoagulation you are getting. This applies to K2 as well as the K1 in leafy greens.
