insightsAnalysis

21st Century's Coral Calcium supplement delivers substantial amounts of calcium (1000mg) and magnesium (1000mg), including a portion from natural coral calcium and also magnesium oxide. The addition of Vitamin D3 (10mcg) is beneficial for supporting calcium absorption and utilization in the body, particularly for bone health.

This supplement is well-suited for individuals seeking higher doses of these minerals and who appreciate a natural source like coral calcium. However, the use of magnesium oxide as a significant portion of the magnesium content means that some of the magnesium may not be as readily absorbed compared to other forms.

thumb_upPros
  • Provides a high dose of both calcium and magnesium per serving.
  • Includes Vitamin D3, which supports calcium absorption.
  • Sourced partially from natural coral calcium.
  • Very high review count indicates widespread popularity.
thumb_downCons
  • Contains magnesium oxide, which is generally less bioavailable than other magnesium forms.
  • The specific form of calcium from 'Coral Calcium' is not explicitly detailed beyond being elemental calcium.
  • Can be a bulky supplement to take due to high dosages requiring multiple capsules per serving.
warningWarnings
  • Magnesium oxide can have a laxative effect in some individuals, especially at higher doses.
  • Those with kidney issues should consult a professional before taking high doses of calcium or magnesium.
  • Ensure adequate water intake when taking calcium supplements.
