What Vitamin K2 MK-4 Brand Are You Using?

Hey guys, so I've been searching for a vitamin K2 MK-4 brand that isnt as expensive as Carlson's 40-50$ a bottle and has more than the much cheaper 100mcg Now Food's has to offer. It also seems that most brands now have a complex of 2-3 Vitamin K's so that makes it even harder for me to find one with just MK-4 that's affordable yet effective. I've searched this subreddit and online to try to find a brand that had at least 1-2mg and isnt 40+ dollars a bottle but havent had any luck.

I'm aware that I could just get Carlson's (reputable brand and more than enough mg) but I just cant justify spending that much money for 5 mg when, although safe, it is not necessary to take that much for it to be considered an effective dose.

​

I'm wondering if there are any other people in similar situations as me and what brand of vitamin K2 MK-4 you guys are using.

​

Thanks!
