Why choose this product

Optimal Calcium Absorption for Indian Lifestyles

21st Century Calcium Citrate Plus D3 Maximum Tablets are formulated for superior absorption, essential for maintaining bone health, especially for active individuals in India. Unlike calcium carbonate, calcium citrate doesn't rely on stomach acid, making it ideal for all adults, including those with digestive sensitivities common in varied Indian diets. This USA-sourced supplement ensures you receive a high-quality formulation, free from gluten, GMOs, and artificial additives, supporting your daily wellness goals effectively. Imported directly, all customs duties and GST are pre-paid, ensuring a transparent and hassle-free purchase.

Who Should Choose This vs. Who Should Consider Alternatives

This supplement is ideal for adults seeking to support bone health, particularly those who find calcium carbonate difficult to digest or have low stomach acid. It's excellent for vegetarians and individuals prioritizing gluten-free, non-GMO options. Those needing a convenient 100-day supply will appreciate the value. However, individuals with specific medical conditions or those on medication should consult a healthcare provider before use. If you require a higher dosage of Vitamin D or specific mineral combinations, consult your doctor for personalized recommendations.

How to use

  • Take with Meals — As a calcium supplement, take two (2) tablets with any meal, twice daily. This ensures optimal absorption and digestive comfort throughout the day.
  • Maintain Dosage — Do not exceed the recommended dosage of four tablets per day. Consistent daily intake is key for supporting bone health and calcium absorption over time.
