L\u2019acide alpha-lipo\u00efque (ALA), aussi appel\u00e9 acide lipo\u00efque ou tioctique, est un antioxydant similaire \u00e0 une vitamine. On dit de l\u2019ALA que c\u2019est un \u00ab antioxydant universel \u00bb en raison de sa caract\u00e9ristique unique d\u2019\u00eatre \u00e0 la fois liposoluble et hydrosoluble.<\/p>\n

Autre aspect particulier de l\u2019ALA : sa capacit\u00e9 de r\u00e9g\u00e9n\u00e9rer d\u2019autres antioxydants en un \u00e9tat actif, notamment les vitamines C et E<\/a>, ainsi que la coenzyme Q10<\/a>. L\u2019acide alpha-lipo\u00efque influe aussi sur la production du glutathion<\/a>, ce qui favorise chez une personne en sant\u00e9 une d\u00e9toxication h\u00e9patique de phase II<\/a>.*<\/p>\n

\u00c0 ce jour, aucun apport quotidien de r\u00e9f\u00e9rence n\u2019a \u00e9t\u00e9 \u00e9tabli pour l\u2019acide alpha-lipo\u00efque. On recommande une dose de maintien de 10 mg \u00e0 25 mg par jour, m\u00eame si des doses quotidiennes pouvant atteindre plusieurs centaines de milligrammes ont \u00e9t\u00e9 utilis\u00e9es.<\/p>\n

On trouve de l\u2019acide alpha-lipo\u00efque en petite quantit\u00e9 dans la plupart des aliments, car presque tous les organismes, humains compris, en produisent naturellement. Les abats (rognons, c\u0153ur et foie), pommes de terre, \u00e9pinards et brocoli sont les aliments les plus riches en ALA.<\/p>\n

\"\"<\/p>\n

Cet antioxydant puissant n\u2019est pas particuli\u00e8rement abondant m\u00eame dans les aliments ayant une forte teneur en ALA. L\u2019un des premiers groupes de chercheurs \u00e0 isoler l\u2019acide alpha-lipo\u00efque a d\u00fb utiliser plus de 9\u00a0000 kilos de r\u00e9sidus de foie pour produire \u00e0 peine 30 mg d\u2019acide lipo\u00efque cristallin. Par cons\u00e9quent, la prise d\u2019un suppl\u00e9ment d\u2019acide alpha-lipo\u00efque est certes un choix judicieux.<\/p>\n

*Ces d\u00e9clarations n\u2019ont pas \u00e9t\u00e9 \u00e9valu\u00e9es par la F\u00e9d\u00e9ration am\u00e9ricaine des aliments et drogues. Ce produit n’est destin\u00e9 ni \u00e0 diagnostiquer, ni \u00e0 traiter, gu\u00e9rir ni emp\u00eacher les maladies.<\/p>\n","protected":false},"excerpt":{"rendered":"
