A Chronic Toxicity Study (L.D.50) has demonstrated that Pharmachem Labortories’ Phase 2 Starch Neutralizer™, which is a standardized white bean extract used in a variety of weight loss supplements, is safe and non-toxic. According to the study, Phase 2 showed no signs of chronic toxicity at doses up to 1.0 gm/kg body weight for up to 90 days. In addition, researchers said that the administration of Phase 2 for 90 days did not produce any adverse reaction as seen from the organ weight, necropsy, haematological values and biochemical values.
