Message definition (Dietary supplement)

===Essential fatty acids===
{{main|Essential fatty acids}}
Fish oil is a commonly used fatty acid supplement because it is a source of [[omega-3 fatty acid]]s. Fatty acids are strings of carbon atoms, having a range of lengths. If links are all single (C-C), then the fatty acid is called ''[[saturated fat|saturated]]''; with one double bond (C=C), it is called ''[[monounsaturated fat|monounsaturated]]''; if there are two or more double bonds (C=C=C), it is called ''[[polyunsaturated fat|polyunsaturated]]''. Only two fatty acids, both polyunsaturated, are considered essential to be obtained from the diet, as the others are synthesized in the body. The "essential" fatty acids are [[alpha-linolenic acid]] (ALA), an omega-3 fatty acid, and [[linoleic acid]] (LA), an [[omega-6 fatty acid]]. ALA can be elongated in the body to create other omega-3 fatty acids: [[eicosapentaenoic acid]] (EPA) and [[docosahexaenoic acid]] (DHA).

必須脂肪酸

魚油はオメガ3脂肪酸の供給源であるため、脂肪酸サプリメントとしてよく使われている。脂肪酸は炭素原子のひもであり、さまざまな長さを持つ。結合がすべて単結合（C-C）であれば、その脂肪酸は飽和脂肪酸と呼ばれ、二重結合（C=C）が1つであれば一価不飽和脂肪酸と呼ばれ、二重結合（C=C=C）が2つ以上あれば多価不飽和脂肪酸と呼ばれる。多価不飽和脂肪酸のうち、食事から摂取することが必須とされるのは2種類だけで、他の脂肪酸は体内で合成される。"必須"脂肪酸は、α-リノレン酸（ALA）とオメガ3系脂肪酸とリノレン酸(LA)とオメガ6系脂肪酸のである。ALAは体内で伸長し、他のオメガ3脂肪酸であるイコサペンタエン酸（EPA）とドコサヘキサエン酸（DHA）を作り出すことができる。
