ModerateUnderdosed
What the lab found
Contained only 80.8% of listed vitamin K2 as trans MK-7 (161.6 mcg instead of 200 mcg). MK-7 instability when combined with large amounts of minerals may explain the degradation.
Failure type · Underdosed
Active ingredient measured significantly below the labeled amount — not therapeutic.
