Studies establish safety of eggshell membrane product

Paper demonstrating natural eggshell membrane ingredient's safety for human consumption can serve as a model for novel dietary ingredient safety evaluations.

This paper, coauthored by Alexander Strauss, Ph.D., of AIBMR, is a safety evaluation of a new dietary ingredient derived from eggshell membrane. A compositional analysis of the material was conducted, and it was subjected to cytotoxicity and mutagenicity evaluations. Acute and 90-day oral toxicity tests in rats were also completed. This article could perhaps serve as a model for novel dietary ingredient safety evaluations.

“Safety evaluation of a natural eggshell membrane-derived product”

 

ABSTRACT
Natural Eggshell Membrane (NEM) is a novel dietary ingredient that contains naturally occurring glycosaminoglycans and proteins essential for maintaining healthy joint and connective tissues. NEM was evaluated for safety via in vitro and in vivo toxicological studies. This included testing for cytotoxicity, genotoxicity, acute oral toxicity, and 90-day repeated-dose oral toxicity. NEM did not exhibit any cytotoxic effects at a dose of 100 μg in an in vitro human cell viability assay after incubation for up to 20 h. NEM did not exhibit any genotoxic effects in an in vitro assay of four strains of histidine-dependent Salmonella typhimurium and one strain of tryptophan-dependent Escherichia coli at a dose of up to 5000 μg/plate. NEM did not exhibit any signs of acute toxicity in rats at a single oral dose of up to 2000 mg/kg body weight, nor signs of toxicity (via urinalysis, hematology, clinical chemistry, or histopathological evaluation) in rats at a repeated oral dose of up to 2000 mg/kg body weight per day for 90 days. The results of these studies suggest that NEM may be safe for human consumption.
