It sounds like the K2 (MK4) is synthetic whereas the K (MK7) is sourced from fermented soy (natto).I want to take a K2 supplement. Which is best, and why?Sadly, I don't eat leafy greens so I do think I also need a K1 supplement. I haven't begun... (more)

There seems to be such a split of opinion on MK4 vs. MK7, and dosage is all over the place too. I have no clue. I found a good source of MK7 from natto, and since natto is one of the rare soy products that is considered acceptable in most real... (more)

According to the below except from Wikipedia (with appropriate citations) k2 is converted from k1 in mammals regardless of gut bacteria. If this is true then is K1 just as good as K2? The MK-4 form of vitamin K2 is produced via... (more)

First of all, K1 to K2 conversion in humans hasn't been studied, so anyone comparing it to beta-carotene or saying it's limited (or saying anything about the conversion) is just guessing. If we go by clinical evidence, vitamin K1... (more)

I'm wondering is there any vitamin k2 at all in conventionally-raised or grain-fed animals? If so, where?

Propably, if you eat the whole animal, like kidneys, marrow, salivary glands? I wonder if its near the tongue, or somewhere else? Organs are like CPU the of the animal, they have everything. Muscle meat is just a casing ;)

I know there is vitamin k2 in grass-fed butter, but is it also in grass fed tallow? I use tallow because I can't have anything to do with dairy products.

Yes it's found in tallow. According to Vitamin K2 and the Calcium Paradox by Dr. Rheaume-Blue, BSc., ND, K2 is found in butterfat of mammalian milk and the organs and fats of animals. It's also present in natto (fermented soybeans), goose liver,... (more)

I'd recommend k2mk4 dops by Thorne @ 1mg/drop. I'd also recommend 3 drops per day with your fattiest meal. I recommend this across the board, and even for myself.

If you want to spend the least, spend that money on K2, it is expensive, particularly the SuperK Lifeextension one, but it is important. D3 you can get from the sun, and it is a pretty cheap supplement, costing a 10-12$ for a whole year of D3,... (more)
