Dr. Feb's Analysis

Scientific Mechanism

This supplement utilizes Calcium derived from oyster shells, a form known for its high elemental calcium content. At the cellular level, Calcium is essential for bone mineralization, muscle contraction, and nerve transmission. The addition of Vitamin D (Cholecalciferol) is critical; it acts as a hormone to regulate calcium absorption in the small intestine. Without sufficient Vitamin D, the body cannot effectively absorb the Calcium provided, rendering it less effective for strengthening the skeletal structure.

Key Benefits

Key benefits include:

  • Supports bone density and structural integrity
  • Aids in preventing calcium deficiency
  • Facilitates proper muscle function and nerve signaling
  • Enhances calcium absorption with Vitamin D

Usage & Safety

The recommended dosage is 1 tablet daily, preferably with a meal to aid absorption. Calcium is best absorbed in smaller doses (500 mg or less), making this single tablet a convenient option. Avoid taking it simultaneously with high-fiber foods or certain medications (like antibiotics or thyroid meds) as it may inhibit absorption. Consult your healthcare provider if you are pregnant, nursing, or taking prescription drugs.
