-
Dental Health: Calcium directed to teeth helps maintain enamel strength and supports oral health, thanks to the combined action of D3 and K2.*
How D3 and K2 Work Together
The synergy between D3 and K2 comes from their complementary roles in calcium metabolism. Vitamin D3 (as cholecalciferol) enhances calcium absorption from the gut. Vitamin K2 (as menaquinone-7) then activates key proteins: osteocalcin, which binds calcium to the bone matrix, and matrix GLA protein, which helps prevent calcium deposition in soft tissues like arteries.* This coordinated action ensures calcium supports bone density and cardiovascular health simultaneously.
Why Take Vitamin D3 and K2 Together?
Taking these two vitamins together makes sense because they work as a team. Vitamin D3 boosts calcium absorption, but without K2 that calcium may not be properly directed. K2 activates osteocalcin and MGP, guiding calcium to bones and teeth and away from arteries.* By combining them, you help maintain healthy bones and a healthy heart with one simple capsule.

For adults, take one (1) vegan capsule daily with food to enhance absorption. Each capsule provides 5,000 IU of vitamin D3 and 180 mcg of vitamin K2 (as MK-7). This is a suitable dosage for maintaining bone and cardiovascular health. Always follow the recommended serving size unless advised otherwise by a health care practitioner.
Frequently Asked Questions
Can I take vitamin D3 and K2 together on an empty stomach?
Because both are fat-soluble vitamins, taking them with a meal containing fat improves absorption. A small amount of healthy fat from food is ideal.
Is it safe to take 5,000 IU of vitamin D3 daily?
For most adults, 5,000 IU per day is within the safe upper limit. However, individual needs vary. If you have a medical condition or take medications, consult your doctor before using this supplement.
Does this supplement contain soya?
No. The vitamin K2 used (MenaQ7) is soya-free. The product is non-GMO and vegan.
Can I take this with blood thinners like warfarin?
If you are taking anticoagulant medication (e.g., warfarin), please consult your health care professional before adding vitamin K2 supplements, as vitamin K can interact with these medicines.
