Belvedere Environmentals, LLC tests SuperMannan capsules (containing the two deactivated yeast ingredients and canberry powder) for safety and purity. Independent labs do the testing on each lot of SuperMannanan to provide independent results.
All raw materials used in Belvedere Environmentals, LLC products conform to CA Prop 65 for heavy metals. Furthermore, Belvedere Environmentals follows dietary supplement industry best practices to ensure microbial safety. We employ the latest generation safety testing with the MEM Elution Test, which provides assurance of biological safety, but does not require the use of laboratory animals.
SuperMannan capsules pass the following tests…always!
Safety Test: MEM Elution Test for cytotoxicity
The MEM Elution Test (ISO) is a qualitative cytotoxicity assay, in which a sample of the test material is exposed to a healthy culture of tissue culture cells for one to two days to examine its effect on those cells. The MEM Elution test is stringent: it is extremely sensitive to substances harmful to animal cells. The MEM Elution Test provides a 0 to 4 cytotoxicity value. A score of 0 is given if the test cells are completely unchanged after 24 hours; a score of 4 is given if the test cells are completely deactivated This rigorous testing also employs positive and negative controls that are tested simultaneously and under the same conditions as the test article: (1) positive control, or material of known toxicity, which have a score of 4, and (2) negative control, or materials known to be harmless, which have a score of 0. Safety is determined by a MEM Elution Test score of 2 or less. SuperMannan ingredients must pass the MEM elution test with a score of 2 or less.
