Ce que c\u2019est<\/h2>\n

Le DHA (acide docosahexa\u00e9no\u00efque) est un acide gras om\u00e9ga-3 \u00e0 longue cha\u00eene. Il est abondant dans les membranes des cellules du cerveau et de la r\u00e9tine. On le trouve surtout dans les poissons gras (saumon, maquereau, sardine, hareng) et les fruits de mer, qui l\u2019accumulent en mangeant des microalgues, les vraies productrices. Le corps peut en fabriquer \u00e0 partir d\u2019un om\u00e9ga-3 v\u00e9g\u00e9tal, l\u2019acide alpha-linol\u00e9nique, mais en faible quantit\u00e9.<\/p>\n

L\u2019Autorit\u00e9 europ\u00e9enne de s\u00e9curit\u00e9 des aliments<\/a> retient pour un adulte un apport ad\u00e9quat de 250 mg par jour d\u2019EPA et de DHA r\u00e9unis, et conseille 100 \u00e0 200 mg de DHA en plus pendant la grossesse et l\u2019allaitement.<\/p>\n

Une dose de 10 ml d\u2019Optirenov apporte 40 mg d\u2019huile riche en DHA, extraite de la microalgue Schizochytrium<\/em>, avec de la lut\u00e9ine, de la z\u00e9axanthine, de la myrtille, de l\u2019euphraise et du ginkgo.<\/p>\n","protected":false},"excerpt":{"rendered":"
