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)

As long as they are miscible (fancy chemist word for mixable), it should work as you describe. Any oil will do it too. Don't bother with MCT oil, try olive oil.

Just from the fact the MK4 is taken in milligrams and MK7 in micrograms, it seems that MK4 is safer. Also, I read on another forum that MK7 doesn't have that effect on teeth.

Lots of K2 supplements say they are "soy-free". But if you dig deeper, you'll find they're almost all DERIVED from soy -- the soy is supposedly all processed out. I don't believe this, because of how sick I got from taking a tobacco-derived K2. ... (more)

Do you have any scientific evidence to support that CLO/HVBO products are more bio-available to your body? I think that the CLO/HVBO is rancid, nutritionally damaged product and taste bad. I stopped taking it.
