High-Potency D3 + K2-7 for Bone Strength, Calcium Control & Heart Health


MegaQuinD₃™ pairs bioactive vitamin D₃ (cholecalciferol) with vitamin K2-7 (MK-7) to support optimal calcium absorption and smart calcium use in bones and arteries — a combo shown to be more supportive than either vitamin alone for bone and cardiovascular health.

  • Helps maintain cardiovascular health via healthy calcium metabolism. 
  • Synergistic D3 + K2-7 formula for superior calcium absorption & utilisation. 
  • Additional whole-body support noted across nerve, mitochondrial and immune function (brand positioning). 

Vitamin D3 (cholecalciferol) 5,000 IU (125 mcg) and vitamin K2-7 (MK-7, MenaquinGold®) 200 mcg per capsule; refer to the product label for full excipient and allergen information.


Adults (18+): Take 1 capsule daily with a meal, or as directed by your healthcare professional. 

  • Always read the label and follow directions for use.
  • If you are pregnant, breastfeeding, taking anticoagulants (e.g., warfarin), or under medical care, seek professional advice before use.
