The ICMR-NIN Recommended Dietary Allowances (2020) revised the calcium RDA for a sedentary Indian adult man (18 to 60 years) to:

• A 600 mg/day
• B 800 mg/day
• C 1000 mg/day ✓
• D 1300 mg/day

Explanation

ICMR-NIN 2020 raised the adult calcium RDA to 1000 mg/day for men and women aged 18 to 60 years, an upward revision from the earlier value of about 600 mg/day based on newer balance studies and bone health data. Requirements are higher in adolescence, pregnancy, lactation, and old age. The older figure of 600 mg appears in pre-2020 editions and remains a tempting distractor for candidates who studied from outdated material.
