Vitamin D-3 & K-2 1000 IU/45 mcg

The evidence-based D3+K2 pairing at NOW Foods prices. D3 helps you absorb calcium. K2 makes sure it goes to your bones, not your arteries. 120 servings for under $15. Four months of bone and heart support for the price of a pizza.

7.5/10
VERY GOOD

D3 at 1000 IU + K2 MK-7 at 45mcg is the right combination for calcium metabolism. D3 is at minimum effective, K2 at minimum effective. The synergy between D3 and K2 for directing calcium to bones (not arteries) is well-established. Both ingredients hit their floor doses. For daily maintenance at 120 servings for under $15, this is excellent value. Would be stronger at higher doses (2000-4000 IU D3, 100mcg K2).

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.
