What Are Vitamin D3 and K2?
Before we explore the products, let’s understand why Vitamin D3 and K2 are crucial for our well-being.
Vitamin D3, also known as cholecalciferol, helps regulate calcium and phosphate in the body, promoting the health of bones, teeth, and muscles. It also plays a role in immune system function.
Vitamin K2, on the other hand, is vital for activating proteins involved in calcium utilization and metabolism. It helps to direct calcium to the bones and teeth while preventing it from accumulating in soft tissues, like arteries.
Benefits of Combining Vitamin D3 and K2
The synergy between D3 and K2 provides powerful benefits:
- Bone Health: Vitamin D3 enhances calcium absorption while K2 helps in depositing the calcium in bones.
- Heart Health: Adequate levels of K2 can help reduce arterial calcification.
- Immune Function: Both vitamins contribute to a robust immune response.
