Vitamin D Plus K by Klaire Labs (SFI Health) delivers a bioavailable pairing of Vitamin D3 (5,000 IU) and Vitamin K2 as MK-7 (100mcg) in a single capsule.* These two nutrients work synergistically: D3 promotes calcium absorption while K2 directs calcium to bones and away from arteries, supporting both skeletal integrity and vascular health.*
Formulated by Klaire Labs — trusted by healthcare practitioners since 1969 — this hypoallergenic formula is free of all major allergens and contains no synthetic colors, flavors, or preservatives.*
Why D3 + K2 Together?
Vitamin D3 enhances calcium absorption in the gut, but without adequate Vitamin K2, excess calcium can deposit in soft tissues and arteries. K2 MK-7 activates proteins that direct calcium to bones where it belongs and inhibit its accumulation in vascular tissue — making this combination essential for anyone supplementing with higher-dose Vitamin D.*

Frequently Asked Questions
Why combine Vitamin D3 and K2?
Vitamin D3 enhances calcium absorption, while K2 MK-7 directs calcium to bones and prevents it from depositing in arteries. Together they provide more comprehensive bone and cardiovascular support than either nutrient alone.*
What is MK-7 and why is it used?
MK-7 (menaquinone-7) is the most bioavailable and longest-acting form of Vitamin K2. It has a longer half-life than MK-4, meaning it stays active in the body longer and provides more sustained cardiovascular and bone benefits.*
Can I take this with blood thinners?
Vitamin K2 may interact with anticoagulant medications such as warfarin (Coumadin). If you take blood thinners, consult your healthcare practitioner before starting this supplement.*
Is this product allergen-free?
Yes. This product is free of milk/casein, eggs, fish, shellfish, tree nuts, peanuts, wheat/gluten, soybeans, and sesame. It contains no synthetic colors, flavors, or preservatives.*
Should I take this with food?
Yes. Vitamins D3 and K2 are fat-soluble, meaning they absorb best when taken with a meal that contains some dietary fat. Taking with food also improves tolerability.*
