1. Fish Oil (Omega-3)

  • Contains EPA and DHA, beneficial for cardiovascular and brain health
  • Multivitamins do not contain Omega-3, need separate supplementation
  • Recommendation: 2-3 times per week of fatty fish (such as salmon, sardines)
  • High-risk groups (coronary heart disease patients) can supplement approximately 1g EPA+DHA daily under doctor’s guidance

2. Calcium Supplements

  • Calcium is key element for bones and multiple physiological functions
  • Calcium content in multivitamins is limited (50-200mg/tablet), far below daily recommended amount
  • Chinese people generally have insufficient dietary calcium, recommend combining diet and calcium supplements
  • Precautions: Divide doses to avoid single-time excess (no more than 500mg/time), total daily not exceeding 2000mg
  • Recommend supplementing with vitamin D and K₂ synergistically to promote absorption

3. Vitamin C

  • Participates in immune, antioxidant, and collagen synthesis
  • Ordinary people can meet needs through fruits and vegetables
  • High-dose supplementation has limited disease prevention effect for healthy people
  • Only consider supplementation in smoking, insufficient diet, or special pathological conditions

Summary

Ordinary people prioritize food-based supplementation; those with specific health problems or insufficient diet should supplement specifically under doctor’s guidance.
