    True K2 the best Mk4 & Mk7 on the market today
    Cis and trans isomers of the vitamin menaquinone-7: which one is biologically significant?
    This would explain any brands of K2 that gave people no effects. I've had success with both Thorne and LifeExtension.

    Nested Naturals, a pure MK7 supplement, gave me zero effects. This might not be due to the MK7, but rather a cheaper synthesis process that produce more cis-isomer.
