How it works
Thorne’s Vitamin D + K2 combines two essential nutrients—vitamins D3 and K2—that work synergistically to support bone health, cardiovascular function, and immune system health. Vitamin D3 is critical for maintaining strong bones by enhancing calcium absorption, while vitamin K2 helps ensure that calcium is properly directed to the bones, rather than accumulating in soft tissues like the arteries and kidneys. This powerful combination of vitamins offers more comprehensive support than either nutrient alone, making it an excellent choice for individuals looking to maintain bone strength and cardiovascular health throughout their lives.
Maintaining optimal levels of both vitamin D and K2 is particularly important as we age. Vitamin D3 plays a crucial role in promoting healthy bone density and immune function, while vitamin K2 helps to protect soft tissues by preventing calcium buildup in the arteries. When these vitamins are paired together, they provide a more effective way to enhance calcium utilization in the body, promoting bone health while simultaneously supporting cardiovascular and immune function. Thorne’s Vitamin D + K2 ensures that your body gets these vital nutrients in their most bioavailable and effective forms for maximum benefit.
Thorne’s Vitamin D + K2 is formulated with MK-4, the most clinically studied and effective form of vitamin K2, and vitamin D3, which is far more potent and easily absorbed than the D2 form found in many other supplements. The liquid form of this supplement makes it easy to customize your dosage, with a self-dispensing top that meters out the exact amount you need for precise and safe dosing. This liquid is also made with a high-quality medium-chain triglyceride oil base and preserved with mixed tocopherols (natural vitamin E), ensuring the product remains fresh and free from unnecessary additives.
This supplement is especially beneficial for those looking to enhance their bone health, cardiovascular support, and immune function. If you’re at risk for a vitamin D deficiency, or if you want to make sure you’re optimizing calcium absorption while protecting your arteries from calcification, Thorne’s Vitamin D + K2 is a must-have addition to your wellness routine. With its combination of these two vital nutrients in the most bioavailable forms, it offers a powerful way to support overall health and vitality.
