What We Like

  • D3+K2 is the scientifically ideal pairing.
  • 120 servings = 4 months supply.
  • NOW Foods quality at budget pricing.
  • MK-7 form of K2 (longer half-life than MK-4).

Watch Out For

  • D3 at 1000 IU may be low for deficient individuals.
  • K2 at 45 mcg is modest (100 mcg is optimal).
  • No absorption enhancer.
