Good question! There is no set recommended intake or upper limit established for vitamin K2... but some research are suggesting a dose of anywhere from 100mcg to 300mcg can be beneficial.
To answer your question, if you take 180mcg of vitamin K2 & also take calcium with K2, this is still within the range... even if you take 4 capsules of calcium, this will provide 100mcg of K2 ... so a total of 280mcg which is still below 300mcg.
So it's not an issue to take both.
Hope that clear things up, and let me know if you have any other questions.
