insightsAnalysis

The 21st Century Calcium 500+D3 offers 500mg of elemental calcium derived from oyster shell, combined with 5mcg (200 IU) of Vitamin D3. Oyster shell calcium is primarily calcium carbonate, often containing natural trace minerals, and the added D3 supports calcium absorption.

This product is a practical choice for individuals seeking to bolster their daily calcium intake for bone and nail health, particularly appealing due to its remarkably low price per serving and generous quantity, making it an excellent long-term supplement option.

  • Includes Vitamin D3 to aid calcium absorption.
