Key Health Benefits

  • Bone Health: Vitamin D3 contributes to normal calcium absorption and vitamin K2 helps incorporate calcium into bone tissue, supporting strong, healthy bones.*
  • Heart Health: By activating MGP, vitamin K2 helps maintain normal calcium balance in the arteries, promoting cardiovascular wellness.*
  • Immune Support: Vitamin D3 plays a role in the normal function of the immune system, helping you maintain overall health.*
  • Dental Health: Proper calcium utilisation supports healthy teeth and gums.*
  • Convenience: This 2-in-1 formula eliminates the need for separate bottles, and each bottle provides a 3-month supply (90 capsules per bottle, 270 in total).

Understanding the Synergy: How D3 and K2 Work Together

Discover Best Value, Strength — Vitamin D3 stimulates the production of calcium-binding proteins in the intestinal lining, enhancing calcium absorption. Once calcium enters the bloodstream, vitamin K2 activates two key proteins: osteocalcin, which helps bind calcium to the bone matrix, and matrix GLA protein (MGP), which may help prevent calcium from accumulating in blood vessels. By taking D3 and K2 together, you support a balanced calcium distribution that promotes bone density and arterial flexibility. The MK-4 form of vitamin K2 used in this supplement is a well-researched bioidentical form that supports efficient utilisation by the body.

What to Consider When Choosing a D3 + K2 Supplement

When selecting a vitamin D3 and K2 supplement, consider the dosage, form of K2, and quality certifications. Our formula offers 10,000 IU of vitamin D3—a potent dose suitable for those with higher needs (always consult your health care provider before starting any new supplement). The K2 is provided as MK-4 at 1,500 mcg, a dose that aligns with clinical research on bone and heart health. The capsules are 100% vegetarian, gluten-free, and made in a GMP-certified facility. Each batch is third-party lab tested for purity and potency, ensuring you receive a high-quality product you can trust. Our lifetime satisfaction guarantee reflects our commitment to your satisfaction.

Why Take Vitamin D3 and K2 Together?

Vitamin D3 and vitamin K2 form a powerful duo that works synergistically to support your body's calcium metabolism. While vitamin D3 helps increase calcium absorption from the gut, vitamin K2 directs that calcium to the bones and teeth where it is needed, and helps prevent it from depositing in soft tissues like arteries. This combination is essential for maintaining strong bones, a healthy heart, and a robust immune system. Our Max Strength formula delivers 10,000 IU of vitamin D3 (as cholecalciferol) and 1,500 mcg of vitamin K2 (as menaquinone-4, MK-4) in each capsule, providing a convenient way to support these critical functions.

Frequently Asked Questions

What is the best form of vitamin K2?

Vitamin K2 exists in two main forms: MK-4 and MK-7. MK-4 has a shorter half-life and is rapidly utilised by the body, while MK-7 lasts longer in circulation. This product uses MK-4, which is the form most commonly studied for bone health and is naturally found in animal foods.

How much K2 should I take with D3?

A common ratio is 100 mcg of K2 (MK-7) per 1,000 IU of D3, but higher ratios like 1,500 mcg K2 (MK-4) with 10,000 IU D3 are also used. The appropriate dosage depends on individual needs, so it is best to consult a health care professional.

Can I take this supplement with blood thinners?

If you are taking anticoagulant medications (e.g., warfarin), consult your doctor before using vitamin K2, as it can interfere with the medication's effectiveness.

Recommended Dosage

Take one capsule daily with a meal containing fat to enhance absorption. Each bottle contains 90 capsules, providing a 3-month supply. As with any supplement, consult your health care provider before uses, especially if you are pregnant, nursing, or have a medical condition.

*Vitamin D contributes to the normal absorption/utilisation of calcium and phosphorus, normal blood calcium levels, maintenance of normal bones, normal muscle function, and normal function of the immune system. Vitamin K contributes to maintenance of normal bones and normal blood clotting. This product is a food supplement. Food supplements should not be used as a substitute for a varied diet and healthy lifestyle. Do not exceed the recommended daily dose.
