Product Description
Vitamin D increases how much calcium your body absorbs, but calcium absorbed isn't automatically calcium delivered to the right place. Vitamin K2 activates the proteins that direct that calcium into bone and away from soft tissue like arteries, which is why the two nutrients are increasingly paired rather than taken separately.
Pure Encapsulations Vitamin D3 & K2 combines both, covering calcium absorption and calcium utilization together.
Directs Calcium Where It Belongs – Vitamin K2 activates matrix Gla-protein, a protein involved in calcium balance that helps keep calcium working for bone rather than building up in arterial tissue.
A Higher-Potency Dose for a Specific Purpose – At 4,000 IU, this delivers more vitamin D per capsule than typical maintenance doses, relevant if blood testing has shown you need more than general daily support.
One Capsule Covers Both Nutrients – D3 and K2 work together in bone metabolism, so getting both in a single daily capsule is simpler than managing two separate products and timing them together.
Vitamin K2 (as MK-7) activates matrix Gla-protein, a key protein involved in calcium balance, supporting arterial calcium balance and vascular elasticity alongside proper calcium utilization in bone. Vitamin D3 and vitamin K2 both participate in regulating osteocalcin, a biomarker of bone formation, and research associates higher vitamin K2 intake with cardiovascular health and healthy vascular calcium balance. This formula combines 4,000 IU of vitamin D3 with 100mcg of biologically active, all-trans vitamin K2 in a single capsule.
How to Use Pure Encapsulations Vitamin D3 & K2
Dose: Take 1 capsule daily, with a meal.
This single capsule provides more than double the 50mcg (2,000 IU) vitamin D threshold at which blood-level monitoring is recommended, so this is generally intended for people with a confirmed need for a higher dose rather than general daily maintenance.

Pure Encapsulations Vitamin D3 & K2 FAQ's
Everything you need to know about Pure Encapsulations Vitamin D3 & K2.



Vitamin D increases how much calcium your body absorbs, but that doesn't automatically mean it ends up in the right place. Vitamin K2 activates the proteins that direct calcium into bone and away from soft tissue like arteries — which is why the two are increasingly paired rather than taken separately.
Take 1 capsule daily, with a meal.
This delivers more vitamin D per capsule than typical maintenance doses, which matters if bloodwork has shown you need more than general daily support. It's generally intended for people with a confirmed need for a higher dose rather than as a baseline daily vitamin.
Vitamin K2 (as MK-7) activates matrix Gla-protein, a key protein involved in calcium balance, supporting arterial calcium balance and vascular elasticity alongside proper calcium utilization in bone.
Vitamin D promotes calcium absorption, but K2 is what directs that calcium into bone instead of soft tissue — the combination supports the calcium utilization your bones need to hold up under the repetitive impact of high mileage or training load.
