Caltrate 600+D3 tablets provide a high-dose combination of calcium carbonate, the body’s primary bone-building mineral, with vitamin D3 to optimize absorption and utilization. Calcium supports bone density, muscle contraction, nerve signaling, and hormone release, while D3 facilitates intestinal calcium uptake and mineralization, reducing osteoporosis risk when part of a balanced diet. This formulation addresses deficiencies common in aging, low-dairy diets, or limited sun exposure, promoting skeletal, joint, and muscular health for active living.
Key Benefits:
- Maximizes calcium absorption with high-level vitamin D3
- Reduces osteoporosis risk through bone mineralization
- Supports nerve, hormone, muscle, and dental health
- Ideal for adults over 50 or with dietary gaps
- Once/twice-daily convenience for maintenance
How to Use
- Administration: Take orally with a full glass of water.
- Dosage: Adults: 1 tablet up to twice daily with food, or as directed by physician. Not for children.
- Timing: With meals to enhance absorption and reduce GI upset.
- Consistency: Daily for optimal bone health; do not exceed recommended dose.
- Duration: Long-term as supplement; reassess with bone density tests.
Expert Tips from CureCart Direct:
- Pair with weight-bearing exercise and sun exposure for synergy.
- Space from iron supplements or dairy (calcium competes).
- Monitor intake from all sources to avoid excess (>2000mg/day calcium).
- Crush if swallowing issue, but prefer whole.
- Annual D levels check for efficacy.
Missed Dose: Take when remembered; skip if near next—do not double.
Overdose: GI upset, kidney stones risk—seek care if hypercalcemia symptoms (nausea, confusion).
Primary Uses
- Bone health maintenance and osteoporosis risk reduction.
- Support for muscles, joints, nerves, hormones, and teeth.
Indications
Indicated as dietary supplement for adults to provide sufficient calcium and vitamin D3, reducing osteoporosis risk when combined with healthy diet/exercise. Suitable for postmenopausal women, elderly, or those with low intake/sun exposure.
Side Effects
Common:
- Mild GI: Constipation, bloating, gas
Less Common:
- Nausea, abdominal discomfort
Serious/Rare:
- Hypercalcemia (excessive thirst, frequent urination)
- Kidney stones (long-term high-dose)
Discontinue if severe; consult for persistent issues.
Warnings and Precautions
- Pregnancy/Lactation: Safe in recommended doses; consult for needs—excess risks fetal harm.
- Driving: No impairment.
- Renal Impairment: Caution; high calcium risks stones/hypercalcemia—monitor.
- Other: Avoid in hyperparathyroidism or vitamin D toxicity. Space from antibiotics/antacids.
Contraindications
Do not use in:
- Known hypersensitivity to ingredients.
- Hypercalcemia or kidney stones history.
- Sarcoidosis or hypervitaminosis D.
FAQs
How does it work? Calcium builds bones/teeth; D3 enhances absorption for mineralization.
Osteoporosis prevention? Yes, with diet/exercise; reduces risk in deficient adults.
GI upset? Common; take with food, divide doses.
Safe long-term? Yes, but monitor levels; avoid excess.
Interactions? With tetracyclines/thyroid meds—space 2 hours.
Related Tests: Bone density (DEXA), vitamin D levels, calcium serum.
Quick Tips:
- With meals.
- Hydrate well.
- Annual checks.
Doctor Review
Dr. Sana Iqbal, MBBS, FCPS – Consultant Endocrinologist “Caltrate 600+D3 combines bioavailable calcium carbonate with cholecalciferol to achieve 100% RDA, enhancing intestinal absorption via VDR upregulation and reducing PTH-mediated bone resorption. RCTs show 20-30% fracture risk reduction in deficient populations, with natriuresis aiding BP control. Monitor 25(OH)D levels (target 30-50ng/ml) to avoid hypercalcemia; enteric coating minimizes GI AEs. Ideal for postmenopausal prophylaxis, but pair with K2 for vascular safety.
