1. Iron Element Differences
| Population | Daily Recommended Intake |
|---|---|
| Women of childbearing age (18-50 years) | 18mg |
| Adult men (19-50 years) | 8mg |
| Pregnant women | 27mg |
- Women need iron supplementation due to menstrual blood loss; men should avoid routine iron supplementation unless iron deficiency is diagnosed
- Vitamin C can promote iron absorption by 2-3 times
2. Calcium Requirements Differences
| Population | Daily Recommended Intake |
|---|---|
| Adolescents (9-18 years) | 1300mg |
| Adulthood (19-50 years) | 1000mg |
| Post-menopausal women (51+ years) | 1200mg |
| Elderly men (71+ years) | 1200mg |
- Women’s bone density peaks at age 30 then declines, recommend ensuring adequate calcium intake from age 25
- Combine with vitamin D (600-800IU/day) to promote absorption
3. Folate Supplementation Guide
- Women planning pregnancy: Start supplementing 400μg/day 3 months before pregnancy
- High-risk groups: 4-5mg/day (requires doctor’s guidance)
- Men’s routine needs: 200-400μg/day
- Standard supplementation can reduce neural tube defect incidence by 50-70%
4. Other Nutrient Differences
- Zinc: Men 11mg/day, women 8mg/day (supports reproductive health)
- Magnesium: Men 400mg/day, women 310mg/day
- Vitamin B group, C: Little difference in requirements between men and women
Scientific Selection Suggestions
- First assess daily dietary intake
- Blood test key nutrient levels (such as serum ferritin, 25-hydroxyvitamin D)
- Choose formula based on test results and physiological stage
- Regularly (every 6-12 months) re-evaluate and adjust
