Key Benefits of Vitamin D3 and K2
Vitamin D3 and K2 work together to keep your bones strong, your heart healthy, and your immune system firing. Vitamin D3 helps your body absorb calcium from food, while vitamin K2 directs that calcium to your bones and teeth instead of soft tissues like arteries. This dynamic duo is a popular choice for anyone wanting to support bone density, cardiovascular function, and overall wellbeing.*
-
Bone Health: Vitamin D3 boosts calcium absorption in the gut, and K2 activates osteocalcin to lock calcium into bone tissue. Together they help maintain solid, healthy bones.*
-
Cardiovascular Support: Vitamin K2 activates matrix Gla protein, which keeps calcium from depositing in artery walls. This helps maintain flexible blood vessels and normal circulation.*
-
Immune Function: Vitamin D3 is known to regulate immune cells, helping you mount a strong defence against bugs.*
-
Teeth and Muscle Health: Proper calcium metabolism also supports dental strength and muscle function.*
Understanding Vitamin D3 vs. D2
Vitamin D comes in two forms: D2 (ergocalciferol) from plants and D3 (cholecalciferol) from animal sources. Research shows D3 is more effective at raising and keeping your blood levels of vitamin D. That’s why NOW Foods uses D3 for optimal absorption.
Similarly, vitamin K2 is the star for bone and heart health compared to K1. Vitamin K1 mainly helps with blood clotting, while K2 activates the calcium-binding proteins you need for strong bones and a flexible heart. The MK-4 form in this supplement is well-studied and easily used by your body.
Who May Benefit from Vitamin D3 and K2 Supplementation?
Plenty of Aussies could do with a bit more D3 and K2. If you spend most of your day indoors—office workers, shift workers, or anyone who slathers on sunscreen—you’re not getting enough sun to make vitamin D naturally. Older adults also produce less D3, so supplementation can help maintain bone density. Even if you’re eating well, this combo gives you a targeted boost where it counts.
If you’re vegan or vegetarian, note that vitamin D3 here comes from lanolin (sheep’s wool), so it’s not strictly vegan—but the capsules are vegetarian-friendly. Chat with your healthcare provider to see if this blend is right for you.
Why Choose a Vitamin D3 and K2 Combination?
Taking D3 and K2 together makes smart use of their synergy. Vitamin D3 boosts calcium absorption, but without enough K2, that calcium might end up in your arteries instead of your bones. This formula gives you both nutrients in one convenient vegetable capsule, so you don’t have to remember two separate tablets. Each serving delivers 1,000 IU of vitamin D3 and 45 mcg of vitamin K2—a well-researched ratio for daily support.*
With limited sun exposure a reality for many of us, supplementing with D3 is a sensible move. Adding K2 ensures the calcium you consume goes where it’s needed most. Whether you’re aiming to maintain strong bones or support heart health, this combo offers a science-backed approach to everyday wellbeing.

How to Incorporate into Your Routine
Take one vegetable capsule daily, preferably with a meal that contains some fat to help absorb these fat-soluble vitamins. Consistency is key—try to take it at the same time each day. Don’t exceed the suggested dose unless your doctor says so.
Safety and Considerations
Vitamin D is fat-soluble and can build up in your body. While 1,000 IU is a moderate dose, consistently taking more than 4,000 IU a day could lead to toxicity. Vitamin K2 has no known toxicity but can interact with blood-thinning medications like warfarin. If you’re on any medication or have a medical condition, check with your healthcare professional before starting this supplement.
Store in a cool, dry place with the lid tightly closed. Keep out of reach of children. Always read the label and follow directions for use.
