Vitamin D3 + K2 to Support Immune Health, Muscle Function, Strong Bones
-
The Power of MK-7 (Menaquinone-7) Not all Vitamin K2 is created equal. Blue Star Nutraceuticals® Vitamin D3 + K2 features MK-7 (Menaquinone-7), the most researched and bioavailable form of Vitamin K2. Compared to other forms of vitamin K, MK-7 remains active in the body for significantly longer, allowing for sustained support of calcium metabolism and bone health with just one daily serving.
-
Premium Cholecalciferol Our product delivers premium cholecalciferol, the same form naturally produced by the body from sunlight to help support bone health, immune function, muscle performance, and overall wellness.
-
Coconut Oil - No Seed Oil Coconut oil is a preferred carrier for fat soluble vitamins, such as Vitamin D3 and Vitamin K2, because they are faster and easier absorbed. Coconut oil is stable and more resistant to oxidation.
What’s Inside
AT A GLANCE
What Vitamin D3 + Vitamin K2 Do For You
-
Supports Strong Bones & Teeth Strong bones require more than just calcium. Vitamin D3 increases calcium absorption, while Vitamin K2 activates proteins such as osteocalcin that help bind calcium directly into bone tissue. This complementary relationship helps support the development and maintenance of strong bones and teeth while promoting proper mineral utilization throughout the body. -
Supports Immune Health Vitamin D3 is one of the most important nutrients for healthy immune function. It helps regulate both innate and adaptive immune responses and supports your body's natural defense systems year-round. Emerging research suggests Vitamin K2 may provide additional support by helping regulate inflammatory pathways and promoting healthy immune balance. -
Supports Healthy Calcium Utilization Calcium is only beneficial when it ends up in the right places. Vitamin D3 helps increase calcium absorption, while Vitamin K2 activates Matrix Gla Protein (MGP), a key protein involved in directing calcium away from soft tissues and toward bones.Think of Vitamin D3 as helping load the calcium, while Vitamin K2 helps guide where it goes. -
Supports Everyday Wellness Modern lifestyles can make it difficult to obtain optimal amounts of both Vitamin D and Vitamin K. Limited sunlight exposure, indoor work environments, seasonal changes, and dietary patterns may all contribute to suboptimal intake. Vitamin D3 + K2 provides daily support for the systems that help keep you healthy, active, and performing at your best.

How Vitamin D3 + K2 Works
-
01 Vitamin D3 Floods the Blood with Calcium Vitamin D3 turns into its active hormone form (calcitriol) and signals your intestines to aggressively absorb calcium. This increases the total concentration of calcium circulating in your bloodstream. -
02 Vitamin D3 Prepares the "Calcium Catcher" Proteins Crucially, Vitamin D3 doesn't just absorb calcium; it also stimulates your body to produce two vital proteins: Osteocalcin and Matrix Gla Protein (MGP). However, when D3 creates these proteins, they are born inactive. -
03 Vitamin K2 Turns on the Proteins (Carboxylation) This is where Vitamin K2 steps in. It provides the "keys" via a biochemical process called carboxylation. K2 activates those two proteins so they can do their jobs. (1) Activated Osteocalcin (The Bone Builder): This protein acts like a magnet for calcium. Once activated by K2, it grabs the calcium floating in your bloodstream and locks it securely into your bone matrix, increasing bone density. (2) Activated Matrix Gla Protein (The Artery Protector): This protein lines your blood vessel walls. Once activated by K2, it actively repels calcium, preventing it from binding to arterial walls and forming hard, dangerous plaques.
