Dr. Feb's Analysis

Scientific Mechanism

This supplement delivers Calcium and Vitamin D3 to support skeletal integrity. Calcium is the primary mineral in bones, providing structural hardness. Vitamin D3 (Cholecalciferol) is essential for intestinal calcium absorption. Without sufficient Vitamin D3, the body cannot efficiently absorb dietary calcium, leading to reduced bone mineralization. Together, they maintain serum calcium levels, supporting bone remodeling and preventing demineralization.

Key Benefits

Key benefits include:

  • Supports bone density and structural integrity
  • Aids in preventing osteoporosis risk
  • Provides 50% Daily Value of Calcium per serving
  • Enhances calcium absorption via Vitamin D3

Usage & Safety

Take 1 tablet daily with food to improve absorption and reduce stomach upset. Do not exceed recommended dosage. Consult a healthcare provider if you are pregnant, nursing, taking medications, or planning a medical procedure. Discontinue use and consult a doctor if adverse reactions occur. Keep out of reach of children.
