DHA添加量并非越高越好，超过总脂肪酸1%的超高DHA可能挤占其他脂肪酸比例并增加氧化风险，日常喂养60-80mg/100g已足够，无需为高数值支付溢价

UnverifiedDHA添加量需≥0.2%总脂肪酸才有临床意义(约3.7mg/100kJ),很多国产奶粉标注含DHA但实际添加量低于此值,选购时看营养成分表每100g的mg数而非仅看是否含有86% similarUnverifiedDHA含量并非越高越好，参考0.2%-0.5%总脂肪酸(约每100kcal含20mg以上)即达欧盟标准，过量堆砌意义有限且推高价格85% similarUnverifiedDHA添加量建议达到总脂肪酸的0.3%以上（约每100g奶粉70-100mg），低于0.2%的补充意义有限；且需关注ARA与DHA比例，通常1:1至2:1较合理85% similarUnverifiedDHA含量需关注实际添加量而非仅看是否标注，建议每100g奶粉DHA≥50mg（占总脂肪酸0.2%-0.5%）才有实际补充意义，低于此量属于'概念添加'84% similarUnverifiedDHA添加量需达到总脂肪酸的0.2%-0.5%才符合国际专家共识（FAO/WHO），换算到常规奶粉约为每100g奶粉含DHA 60-100mg，低于该区间的强化意义有限82% similar
