SCS - Why Does BioShield MD Lack Vitamin K2?
While Vitamin D is usually paired with K2 to help absorption, BioShield MD contains zinc, quercetin, resveratrol, and curcumin that act as a powerhouse for antioxidants and anti-stress properties that also help with absorption of vitamin D.
Zinc can also be paired with Vitamin D for its absorption properties and ensures calcium is going into the right areas (just like K2).
