Calcium K/D

• Vitamin D(Vitamin D (Form: as Cholecalciferol (Alt. Name: D3)) Note: 1,000 IU)

  25 mcg

  Ingredient research · Vitamin D

  Vitamin D is a hormone-like nutrient that helps the body absorb calcium and maintain healthy bones and muscle function. Supplementation can reliably prevent or correct low vitamin D status, particularly when sun exposure is limited, while broader immune, cardiovascular, and metabolic benefits are less certain.

  • Supports bone-density and fracture- or fall-related outcomes.
  • Supports muscle-strength outcomes, including lower-limb strength.
  • Supports glycemic-marker and insulin-sensitivity outcomes in studied metabolic populations.
  • Supports respiratory-infection-risk outcomes across studied age groups.

• Vitamin K(Vitamin K (Form: as Vitamin K1))

  100 mcg

  Ingredient research · Vitamin K

  Vitamin K is an essential fat-soluble nutrient that activates proteins needed for normal blood clotting and bone mineralization. Supplements reliably prevent or correct deficiency and may support bone health when intake or absorption is inadequate; effects beyond this, including cardiovascular benefits, are less certain and can differ between K1 and K2 forms.

• Calcium(Calcium (Form: as DimaCal Di-Calcium Malate))

  400 mg

  Ingredient research · Calcium

  Calcium is an essential mineral that gives bones and teeth their structure and also enables muscle contraction and nerve signaling. Supplements are most useful for filling inadequate intake and, often alongside vitamin D, can help preserve bone mineral density and support fracture prevention in some higher-risk groups.

  • Supports bone-mineral-density outcomes in studied healthy children and older women.

• Vitamin K2(Vitamin K2 (Form: as Menaquinone-7))

  30 mcg

  Ingredient research · Vitamin K2

  Vitamin K2 is a family of menaquinones that activates proteins involved in normal blood clotting, bone mineralization, and calcium regulation. Supplements are mainly used to support bone health, while possible benefits for vascular calcification and cardiovascular health remain less certain and may differ among forms such as MK-4 and MK-7.

  • Supports selected osteocalcin carboxylation markers in postmenopausal osteoporosis.
