Calcium 600 mg + D3 20 mcg
Brand: Walgreens Essentials
Dr. Feb's Analysis
Scientific Mechanism
This supplement combines Calcium and Vitamin D3 to support skeletal integrity. Calcium is the primary mineral found in bones and teeth, providing structural hardness. At the cellular level, Vitamin D3 (Cholecalciferol) is crucial for the absorption of Calcium in the small intestine. Without sufficient Vitamin D3, the body cannot effectively absorb dietary Calcium, leading to reduced bone mineralization. Together, they maintain serum Calcium levels necessary for muscle function and nerve transmission while fortifying bone density.
Key Benefits
Key benefits include:
- Supports bone density and structural integrity
- Aids in proper muscle function and nerve transmission
- Helps prevent calcium deficiencies
- Essential for maintaining healthy teeth
Usage & Safety
Take 1 tablet daily, preferably with a meal to enhance absorption. Calcium is best absorbed when taken in doses of 600 mg or less at a time. Consult a physician if you are pregnant, nursing, taking medications, or have a health condition. Keep out of reach of children.
