Product Details

Zahler BoneFactor is a comprehensive calcium supplement designed for men and women who want proactive, natural support for bone strength, bone density and joint health. This is not a basic calcium tablet. BoneFactor is a synergistic blend of advanced plant-based calcium, vitamin D3, vitamin K2 and magnesium, all working together to deliver real nutritional support for your bones, joints and teeth.

What makes it work:

  • Calcium 800 mg from Aquamin, an advanced algae-derived plant-based calcium sourced from Lithothamnion marine algae, providing a more natural and bioavailable form of calcium than standard calcium carbonate tablets
  • Vitamin D3 1000 IU as Cholecalciferol from Lichen, helping the body absorb calcium effectively and supporting bone density and immune health
  • Vitamin K2 30 mcg as Menaquinone-7, directing calcium to the bones where it is needed rather than allowing it to accumulate in the arteries
  • Magnesium 460 mg from multiple bioavailable forms including Aquamin Magnesium, Magnesium Citrate, Magnesium Aspartate and Magnesium Ascorbate, supporting muscle function, nerve health and overall bone support
  • Strontium 100 mg as Strontium Citrate, a trace element that helps bones continue to grow and strengthen over time
  • Silica 50 mg from Bamboo Stem and Shoot Extract, supporting joint flexibility and connective tissue health
  • Fruitex-B Calcium Fructoborate 216 mg, a natural plant-based boron compound supporting bone health and joint comfort
  • Vitamin C 120 mg as Magnesium Ascorbate, contributing antioxidant support and collagen synthesis for healthy bones and gums

Together this vitamin D3 K2 and calcium supplement creates a complete bone health formula that addresses bone density, joint flexibility and calcium absorption all in one daily supplement.

What you get in every bottle:

  • 120 tablets per bottle, 30 full servings at the recommended dose of 4 tablets
  • Kosher Certified and Halal Approved
  • Vegetarian friendly, non-GMO, gluten free, dairy free, soy free, peanut free, tree nut free and egg free
  • No preservatives or artificial ingredients
