DHA、EPA魚油功效比一比！幫助健康好循環、新陳代謝選這種
Omega-3是人體所需之必需脂肪酸的一種，其中又含有ALA（α-亞麻酸）、EPA （二十碳五烯酸）、DHA（二十二碳六烯酸）(1)。這些不同的成份有不同的功效，因此想透過補充Omega-3脂肪酸來幫助健康，可以依據需求，選擇合適的成分，效果會更精準喔。
魚油EPA、DHA差別在哪？
魚油中DHA含有22個碳原子以及6個雙鍵，因此學名稱作二十二碳六烯酸(2)。
Omega-3中的EPA則含有20個碳原子以及5個雙鍵，所以學名稱作二十碳五烯酸(2)。
DHA其對於嬰幼兒的健康發育與學習力發展來說非常重要，DHA同時也是維持晶亮健康的成分。在飲食中攝取充足的DHA可幫助我們提高學習能力與專注力，相關研究認為老年人因為年紀的增加，體內DHA含量也隨之降低，對於反應能力會有所影響(3)。

EPA則是與循環健康、心情健康有關，對於經常外食、少運動，或者工作高壓的族群，提供暢通維持、加強心情及壓力管理，補充高濃度的EPA有正面效益。

若是有特別的健康促進目的，透過選擇高濃度DHA或是EPA的魚油產品來攝取，幫助會更大。

DHA、EPA魚油什麼時候吃最好？
魚油主要富含Omega-3不飽和脂肪酸，其為脂溶性的化合物，所以在攝取後會需要酵素分解成游離脂肪酸的型態，才能夠被身體利用(14)。因此，會建議於飯後再攝取魚油，其吸收效率會因為有消化酵素的幫助而比較好。
DHA、EPA魚油怎麼挑選？
DHA和EPA屬於Omega-3不飽和脂肪酸，一般在我們的飲食中主要的來源多為魚油，未精製魚油中Omega-3脂肪酸A的含量大約占總脂肪酸量的20-30%左右，所以必須經過精製的過程後，DHA與EPA的含量才會提高(15)。
-
DHA、EPA80%以上濃度魚油：相關研究指出，Omega-3脂肪酸濃度要高，健康促進效果才會好，若有特殊保健目的，則應挑選魚油中DHA或EPA比例80%以上的魚油，才能更有效率的幫助想調理的部分(16)。
-
rTG型式魚油：目前研究結果指出，rTG魚油，吸收率與生物利用率都顯著比EE高， rTG生物利用率更顯著高出EE超過50%(17)。
