Just curious to know what the current wisdom on this supplement is. I've been taking a few drops under the tongue of Thorne's liquid K2 and just want to be sure that it is still considered "safe" and "beneficial". Just worries me a bit seeing the constant news about calcium supplementation now being considered risky, and I wanted to check in to see if there were any updates or recent medical literature about K2 (re it's efficacy, safety, etc...)

Also, how many of you are supplementing with K2?

CanPrev K2 + D3. It comes in a dark blue bottle with a silver cap. It's a Canadian brand but I think they ship internationally.

I ordered from healthdesigns.com which shipped to Australia. Very cheap, still have more than half the bottle left.

Amy,ru certain about this? That that is the actual mechanism? If so, then calcium supplementation could be safe as long as you also supplement K2, D, and Mg. My understanding is that you should supplement with K2, D and Mg but ANY calcium supplementation is superfluous and/or dangerous. In other words, any exogenous Ca supplementation will just increase CVD risk by stiffening up arteries.

Can you only get that brand through a doctor? Doesn't appear to let you order it through the site.

That's what I do as well - there's so much disagreement on MK-7 vs Mk-4 that I decided to get one that has both.

This is one of my main issues with supplementation. There are always piles and piles of co=factors, and often excess consumption of one nutrient (see beta-carotene for classic example) cause problems when not balanced by others. It makes better sense to me to eat a wide variety of highly nutritious foods, and periodically check with Cron-o-meter to see if you have a tendency to unbalance certain nutrients. Otherwise the pill bottle collection gets huge and unwieldy with the accumulation of new nutrients of the week.

Kasra: you aren't eating fat either, from what I've gathered. Do you not feel that the fat soluble vitamins have value in our diet?

Yes. The reason calcium supplementation is risky is because people are flooding themselves with Ca but NOT also upping their intake of magnesium, vitmain D, K2, or any of the other cofactors that help calcium stay in the bones and teeth and keep it out of the soft tissue, where we *don't* want it to go, like our kidneys, blood vessels, and joints.

Taking supplements is a low-risk low-reward game. I'm not supplementing.

I have celiac/wheat allergy and my digestion was wrecked for a while. I definitely saw the effects on my nails (weird ridges, more prone to breakage, random indents and spots). Right now, I'm taking a d3/k2 supplement that comes in a coconut oil base + magnesium, as well as zinc, which my endo told me I was deficient in. It hasn't been long enough to make any sort of judgement just yet but I'll update my progress in a couple of months.

I do too. And I believe that calcium is not (or is much less) a risk if K2 IS supplemented?

Green Pastures cod liver oil/butter oil blend based on a Chris Kresser post that this had K2 plus D3, A, other omega-3 fats coming from a food source rather than pill.

I only supplement with it in the Winter time around here (when cows and chickens go into the barn all season.)

Otherwise, I devour pastured butter, eggs, cheeses, etc in Spring/Summer/Fall months.

I am really interested in getting this right as I have mild, early onset osteoporosis. Currently I supplement magnesium and d3 but not calcium or k2. I'm torn between adding butter oil to the dairy and eggs etc I eat versus a k2 supplement. Also having briefly read some (ok, controversial) Ray Peat stuff I'm not sure I even get enough calcium. Help!

I have experimented with the Thorne drops and with the Green Pastures Butter Oil. I find that any supplemental K2 makes my skin dry (and dry in a weird, papery kind of way) -- have seen others here say the same, but still don't understand the mechanism since it's widely reported to help dry skin, not cause it. It may be that I get enough K2 already from pastured butter and aged raw milk cheese.

I have been taking one drop of d3/k2 daily for about a year now.

I noticed a positive change in my skin (much clearer) within about a week.

Most K2 supplements at vitamin shoppe I have seen are natto (soy) based. It would be nice to have alternatives to that.
