Unverified改善记忆认知优先选DHA含量≥250mg/日的藻油或深海鱼油，且EPA:DHA比例应偏向DHA（如1:4以上），因大脑灰质中DHA占比远高于EPA91% similarUnverifiedPS+DHA/EPA协同配方对认知益处的证据强于单一PS，但DHA含量需≥100mg才有意义；若已单独补充鱼油，选纯PS避免DHA重复摄入即可80% similarUnverified看单粒DHA绝对含量而非鱼油总量：许多产品标注'1000mg鱼油'但DHA仅120-200mg，成人补脑护眼建议每日DHA摄入250-500mg，需据此换算实际服用粒数77% similarUnverified看营养强化优先关注DHA添加量，达到总脂肪酸0.2%-0.5%（约每100kcal含15-25mg）才符合脑发育有效摄入，仅标注'含DHA'但剂量极低无实际意义76% similarUnverifiedPS+DHA协同配方对老年认知支持更优，但DHA需达到足量（≥100mg）才有协同意义，若DHA仅象征性添加几十毫克，不如单独补鱼油76% similar
