insightsAnalysis

21st Century Calcium 500+D3 uses oyster shell as its calcium source, which is primarily calcium carbonate. The inclusion of Vitamin D3 is key, as Vitamin D helps facilitate the body's uptake and utilization of calcium, crucial for maintaining strong bones and teeth.

This supplement is suitable for individuals looking for a moderate dose of calcium combined with the important co-factor Vitamin D3. It can help bridge dietary gaps for those needing to increase their calcium and Vitamin D intake without taking excessively high doses at once.

thumb_downCons
  • Oyster shell calcium is primarily calcium carbonate, which may require sufficient stomach acid for absorption.

  • Tablet form might be large for some individuals.
warningWarnings
  • Oyster shell calcium can sometimes contain trace amounts of heavy metals; however, specific testing information is not provided here.
