Hi Torn 2 tears!
Thanks for your input and experiences! Makes me enthusiastic about my MK4, I have the Life extention super-K, it's got high levels of that in it.
thoughts after reading your input:
Mk4 stays in the blood a lot longer, it makes sense because it has more of a chance to circulate to the soft tissues
Mk4 is less expensive because it is usually extracted from alfalfa, and similar vegetables
Mk7 is the preferred form for bone remineralization in the elderly, it's got a lot of hype because it was popularized some ten years ago.
Mk7 is a byproduct of fermentation cultures, most noteably nattokinkase
