What are the effects of 400 mg of MCHM?
In this study, the administration of 400 mg/kg/day for 4 weeks was associated with erythropoietic, kidney, and liver effects, including increased liver weight, inflammation, and kidney tubular degeneration. The study determined that the No Observed Effect Level was 100 mg/kg/day.
