Futurebiotics Vitamin K2 (MK-7) + Vitamin D3 Tablets are a high-potency bone and heart health supplement formulated to promote optimal calcium absorption, bone strength, and cardiovascular support. This synergistic blend of Vitamin D3 (Cholecalciferol) and Vitamin K2 (as MK-7, Menaquinone-7) ensures calcium is properly utilized — directed to the bones rather than arteries. Each tablet provides 5000 IU of Vitamin D3 and 90 mcg of K2 (MK-7) for maximum bioavailability and effectiveness, supporting strong bones, flexible arteries, and overall wellness.

Dietary Supplement / Bone & Heart Health Support
Key Ingredients
Vitamin D3 (Cholecalciferol, 5000 IU): Enhances calcium absorption in the gut and supports immune and bone health.
Vitamin K2 (as MK-7, 90 mcg): Guides calcium into the bones and prevents arterial calcification.
MK-7 (Menaquinone-7): The most bioavailable form of Vitamin K2 for longer-lasting effects.
Microcrystalline Cellulose: Plant-based stabilizer ensuring consistent potency.
How It Works / Nutritional Science
Vitamin D3 and K2 work in synergy to maintain healthy calcium metabolism:
Vitamin D3 increases calcium absorption from the diet.
Vitamin K2 (MK-7) activates key proteins — osteocalcin and matrix GLA-protein — that transport calcium to bones and prevent it from depositing in arteries.
This targeted delivery system supports stronger bones, healthier arteries, and improved joint and cardiovascular function, especially in individuals with limited sun exposure or aging concerns.
