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... (more)

I take a Life Extension Super K every day. It has K1, K2 MK-4, and K2 MK-7.

I accidentally bought a k2 supplement in the MK-7 form instead of MK-4. Would you bother taking this? Thanks a lot!

There's decent data for K1, and multiple forms of K2, including mk-7 and mk-4. The type of data supporting each is currently different, a testament to the infancy of the state of knowledge on this topic. There's a randomized placebo controlled... (more)

Only MK-4 is implicated in bone health and it is the x-factor in spring butter. Vitamin K1 is converted to MK-4 in the body. Pre-formed is probably more optimal but who knows. I take 5mg of MK-4 almost everyday, I want to make sure I load up... (more)

Dr K has made reference to testing grass-fed butters for Vit K2 levels and has said that Kerrygold tested at zero before, which didn't help with some people's suspicions that KG may not be entirely grass fed. But tartare provided a link to a fact... (more)

I wonder if the K2 doesn't vary wildly with season. I know that the butter is different colours depending on the time of year. Hence why high vitamin butter oil is only from cows fed on summer pasture.

I live in Iceland and we have canned cod livers (in their own oils) and cod liver pate in all the grocery stores. I've started eating these 115g packs during my pregnancy instead of taking cod liver oil as I found I was unable to tolerate taking... (more)

Thorne puts out a K2 that is made in a lab. It is drops, and the drops last a long time. The caveat is that I actually went back to Carlson's 5mg pills, which are made from animal sources, because I didn't feel the Thorne product made me feel as... (more)

Thanks largely to the Weston Price Foundation and all its adherents, we never stop hearing about vitamin K2. My efforts to find the actual evidence to support a benefit of K2 over, say, other variants of the vitamin (such as K1) turn up very... (more)

It depends on how much you weigh and how much you're getting from food. I would say 1g Vit C if you're not getting it from food. But you must be getting some from what you eat. As for K-2 in MK4 / Menaquinone form, 1mg if not getting from... (more)
