Journal of the American Pharmaceutical Association-2004 "Overall, herbal products and dietary supplements promoted for weight loss lack sufficient supporting efficacy and safety data. More research is needed to draw definitive conclusions. Conjugated linoleic acid and pyruvate have the best supporting evidence, but larger and better-controlled trials are needed before pharmacists should recommend these agents to patients seeking to lose weight." The American Journal of Clinical Nutrition-2004 "The evidence for most dietary supplements as aids in reducing body weight is not convincing. None of the reviewed dietary supplements can be recommended for over-the-counter use." American Family Physician-2004 "Currently, no weight-loss supplements meet criteria for recommended use." Journal of the American Dietetic Association-2005 "Many botanical and other types of dietary supplements are purported to be useful for stimulating or enhancing weight loss. Evidence of their efficacy in stimulating weight loss is inconclusive at present." Yukarıdakiler bir çok araştırmadan yapılan derlemelerin sonuçlarıdır. Özetle; Henüz kilo vermeye yardımcı olacak, güvenliği ve etkinliği insanlar üzerinde kanıtlanmış önerilebilecek bir supplement yoktur.
