The chronic toxicity of the Dunaliella salina microalgae was examined to evaluate its toxicity by the exposure of laboratory animals to high doses of Dunaliella salina and to estimate the possibility of using it as a safe supplement. Different hematological and biochemical analysis including complete blood picture (CBC), liver function enzyme activities; aminotransferases (ALT and AST), alkaline phosphatase (ALP), total bilirubin, kidney function tests; urea, creatinine, and albumin, as well as blood glucose level, were measured. The histopathological investigation was also carried out on hepatic, renal and cardiac architectures to examine its safety.
Hence we can conclude that Dunaliella salina has been proven a safe profile up to 100 mg/kg body weight, however, it succeeded to stimulate the Hb synthesis compared to control groups, showing its benifits to be used safely as food additives or protective and curative agent in different diseases in future.
