Highly Bioavailable Vitamin D3 & K2: Our vitamin D3 is the same form of vitamin D naturally produced by your body when exposed to sunlight, giving you the same health benefits of sunshine without UV damage.* And the vitamin K2 is in its top-grade menaquinone-7 (MK-7) form for higher bioavailability & longer retention. We've gone a step further by infusing cold-pressed sunflower oil to maximize the absorption of these two fat-soluble vitamins.
Support Bone, Immune & Heart Health*: While vitamin D3 aids calcium absorption, vitamin K2 directs calcium to bones where calcium is needed most, preventing it from depositing in unwanted areas.* This perfect match works better than taking vitamin D3 alone, supporting optimal calcium utilization and promoting bone, teeth & heart health.* Vitamin D3 and K2 supplements can also regulate immune response and strengthen immune defense all year round.*
