Calcium Carbonate 500 mg and Calcitriol 0.25 mcg + Capsule


What does Caldoz do?

  • Builds and maintains strong bones and teeth
  • Helps in the formation of bone mass
  • Maintains calcium homeostasis
  • Improves balance and muscular strength
  • Treats established post menopausal osteoporosis.
  • Corrects the abnormalities of calcium and phosphate metabolism in patients with renal osteodystropy
Caldoz potential:
  • Orthopedic
  • Gynecology
  • Endocrinology
  • General medicine

Bones are living organs that contain:

  • Bone tissue
  • Cartilage
  • Connective tissue

Bones provide strength and flexibility

  • Contain about 65% minerals, providing the hardness of bone
  • Contain 35% organic structures for strength, durability, and flexibility (collagen)
  • Hydroxyapatite: mineral crystals around collagen designed to bear weight

Calcium is the most recognized nutrient associated with bone health

Also essential for bone health:

  • Vitamins D and K
  • Phosphorus
  • Magnesium
  • Fluoride
  • Calcium absorption is enhanced in an acid environment. It requires 1,25-dihydroxyvitamin D
  • Provides structure for bones and teeth
  • Assists with acid−base balance
  • Helps in transmission of nerve impulses
  • Assists in muscle contraction
  • Maintains healthy blood pressure
  • Initiates blood clotting
  • Regulates hormones and enzymes
Calcium Intake:
  • Adequate Intake (AI) varies with age and gender: 500 mg to 1,200 mg/day
  • RDA ICMR- Infant 500, Adult 600, Teen:800 P&L 1200
  • Upper limit (UL): 2,500 mg

Bioavailability: Body’s ability to absorb and utilize calcium depends on

  • Individual’s age and calcium need
  • Dietary calcium and vitamin D
  • Binding factors (phytates, oxalates) in foods
Calcium deficiency:

Osteoporosis from long-term calcium deficiency

Hypocalcemia (low blood calcium)

  • Causes: kidney disease, vitamin D deficiency, or diseases that inhibit the production of PTH
  • Symptoms: muscle spasms and convulsions
Vitamin D
  • Fat-soluble vitamin
  • Excess is stored in liver, adipose tissue
  • Can be synthesized by the body from exposure to UV rays from the sun
  • Considered a hormone: synthesized in one location and regulates activities in other parts of the body
Functions of Vitamin D:
  • Regulates blood calcium levels (regulates calcium and phosphorus absorption from the small intestine)
  • Stimulates osteoclasts when calcium is needed elsewhere in the body
  • Required for bone calcification
  • May decrease cancer growth
  • Involved in cell differentiation
Sources of Vitamin D:

Ergocalciferol (D2): plants, supplements

Cholecalciferol (D3): animal foods, sun

  • Most foods naturally contain little vitamin D
  • Mostly obtained from fortified foods (e.g., milk)
  • High amounts: cod liver oil, fatty fish (salmon, mackerel, and sardines)
  • Vegetarians not consuming milk products receive vitamin D from the sun, fortified soy or cereal products, or supplements
Vitamin D deficiency:
  • Loss of bone mass: from fat malabsorption
  • Rickets (children), osteomalacia (adults)
  • Medications alter vitamin D metabolism and activity: glucocorticoids, phenobarbital
