Maintaining strong bones, a healthy immune system and proper calcium balance requires a combination of nutrients that work together. Members Mark Vitamin K2 + D3 provides two key vitamins in a single daily soft gel capsule, featuring 5000 IU of vitamin D3 and 180 mcg of MenaQ7® MK-7 vitamin K2—a well-studied, highly bioavailable form. This 150-count bottle offers a convenient five-month supply, making it easy to support your daily nutritional needs.

Key Health Benefits

  • Bone maintenance: Vitamin D and vitamin K both contribute to the maintenance of normal bones. Vitamin D contributes to normal absorption and utilisation of calcium and phosphorus.
  • Normal blood clotting: Vitamin K contributes to normal blood clotting, an essential function for overall health.
  • Immune function: Vitamin D contributes to the normal function of the immune system and helps support normal muscle function.
  • Calcium distribution: By combining D3 and K2, this supplement helps ensure calcium is used effectively throughout the body.

Why Take Vitamin D3 and K2 Together?

Vitamin D3 and K2 work in harmony. D3 enhances calcium absorption from the diet, while K2 helps activate proteins that bind calcium to the bone matrix and support normal blood clotting. Taking them together optimises the benefits and simplifies your daily routine.

Understanding the Synergy: How D3 and K2 Work Together

Vitamin D3 (cholecalciferol) supports the production of calcium-binding proteins in the gut, improving calcium uptake. Vitamin K2, specifically as menaquinone-7 (MK-7), helps activate osteocalcin (which binds calcium to bone) and matrix GLA protein (which contributes to normal vascular health). The long half-life of MK-7 provides sustained activation of these proteins throughout the day, making it an ideal partner for daily D3 supplementation.

What to Look For in a D3 + K2 Supplement

Not all D3 and K2 supplements are created equal. This formula stands out with MenaQ7®—a clinically studied MK-7 form of vitamin K2 known for its superior bioavailability and longer duration of action. Each soft gel capsule provides 180 mcg of K2 and 125 mcg (5000 IU) of vitamin D3 from lanolin. The product is manufactured in the USA, is gluten-free, sugar-free, and contains no artificial flavours or synthetic colours. With 150 soft gel capsules per bottle, it offers a convenient five-month supply for consistent daily undertake.

Recommended Dosage

The suggested serving is one (1) soft gel capsule daily with food. Each soft gel capsule provides 5000 IU of vitamin D3 and 180 mcg of vitamin K2 (MK-7). Individual needs may vary; we recommend consulting a health care professional to determine the appropriate dosage for your specific health goals.

Frequently Asked Questions

Can I take vitamin D3 and K2 separately?

Yes, but taking them together ensures optimum synergy. D3 increases calcium absorption, and K2 helps direct it to the right places. Many users find that combining them simplifies their routine and optimises benefits.

When is the best time to take this supplement?

Take one soft gel capsule daily with a meal that contains fat, as both D3 and K2 are fat-soluble. This enhances absorption and effectiveness.

Are there any side effects or interactions?

This supplement is generally well tolerated. However, if you are taking blood thinners (e.g., warfarin), consult your health care professional before undertake, as vitamin K2 may interact with anticoagulant medications.
