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

La spiruline est le nom courant de cyanobact\u00e9ries du genre Arthrospira<\/em> (anciennement Spirulina<\/em>), comme Arthrospira maxima<\/em> et Arthrospira platensis<\/em>. On la dit souvent algue, mais c\u2019est une bact\u00e9rie capable de photosynth\u00e8se<\/a> qui forme des filaments en spirale dans les lacs chauds et alcalins des r\u00e9gions tropicales. S\u00e9ch\u00e9e, elle contient 60 \u00e0 70 % de prot\u00e9ines, de la phycocyanine, le pigment bleu qui lui donne sa couleur, des vitamines du groupe B et des min\u00e9raux. Sa vitamine B12 est surtout une forme inactive chez l\u2019humain : l\u2019Anses<\/a> rappelle qu\u2019elle n\u2019est pas une source fiable de B12 pour les personnes qui ne mangent pas de produits animaux.<\/p>\n

Une m\u00e9ta-analyse de 7 essais<\/a> trouve une baisse du cholest\u00e9rol total, du LDL-cholest\u00e9rol et des triglyc\u00e9rides, et une hausse du HDL-cholest\u00e9rol, chez les personnes qui en prenaient.<\/p>\n

Une dose journali\u00e8re de 10 ml de Vita\u00e9lix apporte 250 mg de spiruline, avec du pollen, de la gel\u00e9e royale, de la maca, du Panax ginseng, du ginseng am\u00e9ricain, de la rhodiola et du ginseng sib\u00e9rien.<\/p>\n","protected":false},"excerpt":{"rendered":"
