Vitamin d3 addition - We recommend that adults get between 125 mcg and 200 mcg of vitamin D3 every day. This supplement delivers 25 mcg, which makes it a great way to round out your vitamin D3 intake if you’re getting it from another source, or help you break up your vitamin D supplementation throughout the day.

Bone & brain health - Vitamin D helps get calcium into your bone matrix—the lattice-like structure that gives your bones their strength and rigidity. Vitamin D is good for your brain, too: healthy levels of vitamin D3 have been shown to correspond to better cognitive health scores as you age!

Immune health & supporting already-healthy blood pressure – Vitamin D3 plays a critical role in immune function. It also promotes endothelial health and can help maintain already-healthy blood pressure…which makes getting enough daily vitamin D3 a really, really good idea!

VITAMIN K FOR ARTERIAL HEALTH - Vitamin K is involved in how calcium interacts with your arterial walls, encouraging healthy calcium balance in your arteries. But it can be hard to get enough vitamin K from food sources.

GETTING ENOUGH K2 – Vitamin K2 comes from meat, eggs and cheeses. Some people avoid these foods for health reasons, which can make it hard to get enough. This supplement contains the form of vitamin K2 called MK-7, which has been clinically studied for arterial health.

STAYS IN YOUR SYSTEM - Vitamin K2 remains biologically active in the body far longer than vitamin K1: measurable levels of K2 (MK-7) have been detected 72 hours after you ingest it. That gives your body more time to make use of all that heart-healthy vitamin K

MULTI-NUTRIENT FORMULA FOR HEALTHY BONES - Give your bone cells the nutrients they need to maintain strong, healthy bones, especially because bone density begins to decline over time. Our science-based formula combines a high dose of a special kind of vitamin K2 (menaquinone-4) with three forms of easily absorbed calcium, vitamin D3 and trace minerals such as zincand boron, magnesium, silicon and manganese—all of which are essential for optimal bone health.

GOOD TO THE BONE - During development, your bones go through a growth phase until they reach a peak mass where remodeling and upkeep occur. But this process begins to decline naturally over time and leads to age-related bone density loss. While calcium is crucial for bone health, bones need more than this one mineral to thrive. So, we added vitamins D and K and trace minerals for comprehensive support.

THE SPECIAL “K” IN BONE HEALTH - Studies show that the right kind of vitamin K2 (menaquinone-4), in the right dose, can help maintain healthy bone density. That’s because this vitamin has been shown to be essential for mineralization, the process of binding calcium and depositing in the bone. We added vitamin D3 and calcium because studies show that this combination supports healthy bone mass density.
