Supersmart Vitamin K2 MK-7 with Vitamin D3, 90 mcg, 60 Soft gel capsules

Key Health Benefits

Vitamin D3 and Vitamin K2 (as MK-7) deliver complementary benefits for your body. Vitamin D3 contributes to the normal absorption and utilisation of calcium and phosphorus, helping maintain normal bones and teeth. Vitamin K2 contributes to normal blood clotting and also helps maintain normal bones by activating osteocalcin, which binds calcium to the bone matrix. Together, they support a healthy calcium balance.

• Bone Support: Both vitamins contribute to normal bone maintenance. By directing calcium where it is needed, K2 helps optimise bone density.
• Dental Health: Vitamin D3 helps maintain normal teeth, while K2 supports tooth mineralisation via osteocalcin.
• Immune Function: Vitamin D3 is recognized for its role in normal immune system function, helping the body defend against seasonal challenges.
• Blood Clotting: Vitamin K2 contributes to normal blood clotting, a process essential for overall health.

How D3 and K2 Work Together

Vitamin D3 (cholecalciferol) encourages the production of calcium-binding proteins in the intestinal lining, facilitating calcium absorption. Once calcium enters the bloodstream, vitamin K2 (menaquinone) activates two critical proteins: osteocalcin, which binds calcium to the bone matrix, and matrix GLA protein (MGP), which helps prevent calcium deposition in soft tissues such as blood vessels. This synergy ensures that the calcium you absorb is directed to your skeleton and teeth, rather than accumulating elsewhere.

The MK-7 form of vitamin K2 is preferred because it has a longer half-life than MK-4, providing sustained activity throughout the day. Supersmart undertake MK-7 derived from fermented chickpea, ensuring high bioavailability and stability. The soft gel capsule format includes olive oil, which aids the absorption of these fat-soluble vitamins.

Why Combine Vitamin D3 and K2?

Taking these two vitamins together is especially beneficial for those supplementing with vitamin D3 alone. Increased calcium absorption from D3 without adequate K2 may lead to the deposition of calcium in blood vessels. By pairing D3 with K2 as MK-7, you help maintain a healthy calcium balance, directing calcium to the bones and teeth and away from soft tissues.

This combination is a convenient way to ensure you get both nutrients in appropriate doses, optimising their synergistic effects.

What to Look For in a D3 and K2 Supplement

When selecting a combined supplement, consider the form and dose of vitamin K2. MK-7 is ideal for sustained benefits, and a daily dose of 90 mcg (as in this product) aligns with clinical research. For vitamin D3, a dose of 1000–5000 IU is common; this product provides a balanced amount. Look for non-GMO and gluten-free certifications, as well as third-party testing for purity. Supersmart’s formula is made with olive oil to enhance absorption, and the soft gel capsules contain no unnecessary additives.

Recommended Dosage

Take one soft gel capsule daily with a meal. Each soft gel capsule provides 90 mcg of vitamin K2 (as MK-7) and a complementary dose of vitamin D3. For personalised advice, consult your health care professional, especially if you have a medical condition or are taking medication.

Frequently Asked Questions

What is the best time to take D3 and K2? Since they are fat-soluble, take with a meal that contains fat for optimum absorption.

Can I take D3 and K2 separately? Yes, but taking them together ensures synergistic benefits. This product combines them conveniently.

Are there any side effects? Generally well tolerated. Vitamin K2 may interact with blood thinning medications such as warfarin; consult your health care provider if you are on anticoagulants.

Is this supplement vegan? The vitamin D3 is from lanolin (sheep’s wool), so it is not suitable for vegans. However, the K2 MK-7 is from non-soya fermentation.
