I just wanted to post something anecdotal on this forum. For the past 6 months I have used MK7 for the first 2 months (90mcg/day Jarrow's) and then MK4 for the the next 2 months (3mg/day, Thorne), then switched back to MK7. The rest of my supplementation regimen did not change and I took it at the same time (dinner) everytime. I have to say that on MK4 my teeth are smoother, any sensitivities I have disappear, and they have less stains. While on MK7 it seems like my dental health degrades. I have just switched back to MK4 and I'm noticing a improvement in dental health again. From now on I'm sticking with MK4. Does anyone else experience this effect?
I know this is a slightly older thread, but rather than start a new one I just wanted to chuck another anecdotal experience into the pot. I've noticed the same things with regard to MK4. Or rather, I was just going about my business not paying attention, and people close to me started commenting on my teeth. So yesterday I gave them a good examination in the mirror and it's quite true - my teeth look better. They have less stains and look more universally colored. For a number of years they've had that weird mottled look, I don't know what it's called, but as a layman the best description is that they looked varied in density with some spots appearing "denser" than others, and the tips almost looking translucent to a degree. I'm sure it was just a pattern of staining. This is great, because I have been concerned about my teeth as I get older. All of my tea, coffee & nicotine use really started catching up with my oral health.
I've also noticed my gums, which are pretty healthy to begin with, look healthier.
This is the first winter I've supplemented with D3 and MK4. 5000iu and 5mg respectively, and whatever is in vimmortal. I take the d3 on alternate days.
