Best Value Max Strength 10,000 IU Vitamin D3 and 1,500 mcg Vitamin K2 (MK4) Food Supplement

What Makes This D3 + K2 Formula Different?

Our Max Strength formula delivers a potent dose of 10,000 IU of vitamin D3 (cholecalciferol) alongside 1,500 mcg of vitamin K2 (menaquinone-4, MK4) in each vegetarian capsule. This carefully balanced combination is designed for those who want robust support for bone density, immune function and cardiovascular wellness. Manufactured in a GMP-certified facility and lab-tested for purity and potency, it offers a three-month supply in a single bottle.

Understanding the D3-K2 Synergy

Vitamin D3 helps increase calcium absorption from the gut, but without vitamin K2, that calcium may not be directed properly. K2 activates two essential proteins: osteocalcin, which binds calcium to the bone matrix, and matrix Gla protein (MGP), which helps prevent calcium deposition in soft tissues like arteries. By taking D3 and K2 together, you support a more complete calcium management system—particularly important if you are on a high-dose vitamin D protocol.

Key Health Benefits

• Bone Support: Vitamin D3 contributes to normal calcium absorption, while K2 helps incorporate calcium into the bone structure, supporting bone mineral density.
• Heart Health: K2’s activation of MGP helps maintain arterial flexibility and promotes normal calcium balance in the cardiovascular system.
• Immune Function: Vitamin D3 is recognized for its role in supporting a healthy immune response.
• Dental Health: Proper calcium utilisation also benefits teeth by helping to maintain strong enamel and dentin.

This food supplement is designed to complement a balanced diet and healthy lifestyle. Individual results may vary.

Choosing the Right D3 and K2 Supplement

Not all D3 and K2 combinations are created equal. The form of K2 matters: MK-4 (as used here) has a shorter half-life than MK-7 but remains effective and well-researched. The dosage ratio also counts—this product provides a potent 10,000 IU of D3 paired with 1,500 mcg of K2, suitable for those needing extra support. Quality is assured by GMP certification, lab testing, and a 100% vegetarian, gluten-free formulation.

Frequently Asked Questions

Q: Can I take this food supplement if I am on blood thinners?
A: If you take anticoagulant medications like warfarin, consult your health care provider before using vitamin K2, as it may interfere with the medication’s effectiveness.

Q: When is the best time to take this product?
A: To maximise absorption, take with a meal that contains some fat, as both D3 and K2 are fat-soluble vitamins.

Q: Is this product suitable for vegans?
A: The capsules are vegetarian and free from animal-derived ingredients, but vitamin D3 is typically sourced from lanolin (sheep’s wool). Those seeking a vegan alternative may wish to choose a D2 or lichen-based D3.
