Premier Vitamin D3 + K2 from Premier Research Labs is a high-quality synergy of Vitamins D3 and K2.

Vitamins D and K2 are both fat-soluble vitamins, playing pivotal roles in several critical physiological processes, particularly in maintaining bone health and calcium metabolism. PRL produce a very high quality liquid-capsule version of this important synergy.

  • Supports health bones and teeth
  • Supports immune function
  • Resists calcification of soft tissues.
  • Helps maintain healthy cardiovascular function
  • Supports healthy inflammatory response
  • Can be protective for the respiratory system
  • Important for maintaining healthy thyroid function.


Vitamin D3, often referred to as the "sunshine vitamin," is crucial for the regulation of calcium and phosphorus metabolism in the body. It enhances the absorption of calcium from the diet, which is a fundamental mineral for maintaining bone density and strength. When dietary calcium intake is insufficient, Vitamin D3 helps maintain blood calcium levels by facilitating its release from the bones, ensuring that vital cellular functions that depend on calcium are not disrupted.

Furthermore, Vitamin D3 supports the immune system, contributing to the body's defence against various pathogens. It also plays a role in muscle function and may impact mood regulation, possibly helping to alleviate symptoms of depression.

Vitamin K2, on the other hand, is instrumental in managing the direction of calcium within the body. It promotes the calcification of bones, which is vital for maintaining bone strength and integrity. Interestingly, while it enhances bone calcification, Vitamin K2 paradoxically helps in reducing the calcification of soft tissues, such as the kidneys and blood vessels. This property is particularly significant in cardiovascular health, as it helps prevent the hardening of arteries—a major risk factor for heart diseases.

This supplement is an important synergy between Vitamin D3 and K2, which is why they are often found together in supplements. Vitamin D3 facilitates the absorption of calcium in the intestines, while Vitamin K2 activates osteocalcin, a protein that integrates calcium into bones and teeth. This collaboration ensures that calcium is not only absorbed efficiently but is also directed to the right areas in the body, promoting strong bones and teeth while preventing the unwanted calcification of soft tissues. There is growing evidence that Vitamin D3, in combination with K2, may play a role in supporting cognitive health, reducing inflammation, and even aiding in the regulation of blood sugar levels.

Premier Research Labs' produces one of the highest quality Vitamin D3 and K2 combinations. These are liquid containing capsules for high absorption and utlity.
