Safety & Warnings

Do not exceed the recommended daily dose. Food supplements should not replace a varied and balanced diet and a healthy lifestyle. If you are pregnant, breastfeeding, under 18 or taking any medication, consult a doctor before use. Stop use if adverse reactions occur.

Interactions: Vitamin K2 can interact with anticoagulant medications, such as Warfarin (Coumadin). Warfarin works by inhibiting the action of Vitamin K-dependent clotting factors to prevent blood clots. Supplementing with Vitamin K2 can counteract the effects of warfarin, potentially reducing its effectiveness and increasing the risk of clot formation. Caution should also be taken those supplementing with Calcium as Vitamin D3 can increase Calcium absorption, potentially, to dangerous levels. If you are taking these medications or any other medication, please first speak with your doctor before adding Vit D3 and K2 to your supplement regime.

For further information regarding any other potential drug and supplement interactions of Vitamin D3 and K2 please see the individual ingredient profiles on Drug Bank.* Allergy: This product does not contain any common allergens; however, it should not be used by anyone with a history of hypersensitivity to its ingredients or those taking medications that may interact with it.

Foundational

Vitamin D and K are vital for health. Vitamin D supports bone health by aiding calcium absorption, boosts immune function, and may protect against certain diseases. Vitamin K is essential for blood clotting and helps direct calcium to bones and away from arteries, preventing calcification. Together, they work synergistically to maintain bone and cardiovascular health.

The Synergistic Interplay between Vitamins D and K for Bone and Cardiovascular Health: A Narrative Review – Narrative Review

Outcome: Vitamin D enhances the production of vitamin K-dependent proteins, which, when activated by vitamin K, promote bone mineralisation and prevent soft tissue calcification. Together, they improve bone health more effectively than when taken separately.

Summary: This review suggests that taking both vitamin D and vitamin K together could be better for bone health than taking either one by itself.

Immune System

Vitamin D and the Immune System – Review

Outcome: Vitamin D supports the immune system by enhancing protective immunity and may reduce the risk of autoimmune diseases.

Summary: Vitamin D plays a crucial role in modulating both the innate and adaptive immune responses. Deficiency in vitamin D is linked to higher susceptibility to infections and autoimmune diseases, suggesting that maintaining adequate levels of vitamin D is important for immune health.

Everything You Need To Know About Vitamin D3 & K2

Vitamin D3 (cholecalciferol) is the form of vitamin D that the body naturally produces when the skin is exposed to sunlight. It helps regulate calcium absorption and supports immune function. Vitamin K2 (menaquinone) is a fat-soluble vitamin that plays essential role in directing calcium to the bones and teeth preventing its deposition in arteries and soft tissues.

Vitamin D3 plays a role in calcium calcium absorption in the small intestine by binding to Vitamin D receptors (VDRs) in the gut, promoting the production of calcium-binding proteins that transport calcium into the bloodstream. Vitamin D3 also binds to VDRs on immune cells, such as T-cells and macrophages, activating the body’s defense against pathogens enhancing their ability to identify and eliminate harmful invaders.

Once calcium is absorbed, Vitamin K2 ensures that it is directed to the bones and teeth rather than accumulating in soft tissues like arteries. K2 activates two key proteins: osteocalcin and matrix Gla-protein (MGP). Osteocalcin binds calcium to the bone matrix, strengthening bone density, while MGP binds excess calcium in the blood and prevents its deposition in arteries and other soft tissues.

In a healthy body, D3 and K2 work together to absorb calcium and direct it to bones, supporting bone health and reducing fracture risk. Calcium absorption and proper utilisation are essential for maintaining bone density. Ageing, insufficient Vitamin D3, or poor sun exposure reduce calcium absorption, while low K2 levels impair calcium deposition in bones. This can lead to weakened bones and conditions like osteoporosis.  Improper distribution can also lead to arterial calcification, increasing the risk of cardiovascular issues.

As we age, maintaining optimal bone density becomes crucial to prevent fractures, while avoiding arterial calcification is essential to reducing the risk of heart issues. Ensuring proper calcium absorption and utilisation helps maintain skeletal strength and cardiovascular health, supporting a more healthier more independent life.

Consider the following statements. If you find one or more relatable, Vitamin D3 and K2 might be the support you’ve been searching for:

  • I have a vitamin D deficiency and would like to explore Vitamin D3 and K2 to correct this.
  • I want to support strong and healthy bone density, especially as I age.
  • I’ve learned that Vitamin D3 and K2 can help protect against calcium buildup in the arteries.
  • Despite eating a balanced diet, I’m concerned I’m not getting enough vitamin D from sunlight, especially in the winter months.
  • I’ve read that vitamin K2 works with vitamin D to ensure calcium is properly utilised by my body.
  • I want to boost my immune system, particularly during flu season or times of stress.
  • I’ve been recommended Vitamin D3 and K2 by a health professional.

Frequently Asked Questions

Yes. A hormone is a signaling molecule produced by glands and transported through the bloodstream to regulate physiology and behavior. Vitamin D is considered a hormone because, once produced in the skin from sunlight exposure, it undergoes conversion in the liver and kidneys to its active form (calcitriol), which then acts as a signaling molecule to regulate calcium and phosphate levels.

Studies have shown that vitamin k may help improve cardiovascular health by reducing the calcification of arteries and decreasing the risk of heart disease.

This product contains  Vitamin K2 known as Menaquinone 7 (MK7). MK7 is what is called a long-chain form of K2, it’s found naturally in fermented foods like Natto. The advantage of this form of K2 is that although it’s absorbed slowly, it has a much longer half-life (how long it remains in the body) than other forms of K2 meaning that needs to be taken less frequently.

Magnesium is essential for activating Vitamin D and plays a role in supporting bone formation.
