How Vitamin D3 and K2 Work Together

Vitamin D3 (cholecalciferol) is the most bio-available form of vitamin D, naturally produced when skin is exposed to sunlight. It plays a fundamental role in the absorption and utilisation of calcium from the digestive tract.* Vitamin K2, specifically the menaquinone‑7 (MK‑7) form, activates proteins that help bind calcium to the bone matrix and prevent calcium from depositing in blood vessel walls. Together, they ensure that calcium is properly directed to where it’s needed most.

* Vitamin D contributes to normal absorption and utilisation of calcium and phosphorus, to normal blood calcium levels, and to the maintenance of normal bones.

Key Advantages of This Combination

• Bone strength support: Vitamin D3 enhances calcium absorption, while K2 activates osteocalcin to incorporate calcium into the bone mineral structure. Both vitamins contribute to the maintenance of normal bones.
• Cardiovascular health: K2 supports arterial flexibility by activating matrix Gla‑protein, which helps keep calcium out of vessel walls.
• Immune function: Vitamin D3 contributes to the normal function of the immune system.*
• Calcium utilisation: Adequate vitamin D status supports normal blood calcium levels and bone mineralisation.*

Who May Benefit from Supplementation

Many people have limited sun exposure due to indoor lifestyles, northern latitudes, or sunscreen uses, which can reduce endogenous vitamin D production. Older adults, individuals with darker skin, and those following vegan or dairy‑free diets may also be at higher risk of insufficient intake. Vitamin K2 is less abundant in modern diets than vitamin K1 (found in leafy greens), so supplementation can help fill the gap. If you take high‑dose vitamin D without K2, adding K2 may help direct calcium more effectively.

Recommended Usage for Best Results

As a food supplement, take one tablet daily with a meal that contains some fat — since both vitamins are fat‑soluble, a meal with healthy fats (such as avocado, nuts, or olive oil) enhances absorption. Each tablet provides 100 µg of vitamin K2 (as menaquinone‑7) and 25 µg (1,000 IU) of vitamin D3. This dosage is appropriate for general maintenance; higher therapeutic doses may be recommended by a health care professional based on blood levels.
