Oral toxicity study of sports nutritional powder in Wistar rats: A 90 day repeated dose study

[Display omitted] •Fitnox is a newly developed dietary ingredient for physical endurance.•Fitnox is a unique blend of M. oleifera, P. granatum and K. parviflora extracts.•Fitnox has no toxic potential even at oral dose of 1000 mg/kg in rats.•No significant changes in body weight, biochemistry and hematological parameters.•NOAEL is considered to be 1000 mg/kg body weight in both the sexes rats. Fitnox is a newly developed dietary ingredient for physical endurance composed of the extracts of Moinga oleifera leaf (45–50%), Kaempferia parviflora (black ginger) root (15–20%) and Punica granatum peel (25–30%). The aim of this study was to assess the subchronic oral toxicity of Fitnox (test substance) - in Wistar albino rats. Forty rats equally divided into 4 groups (control male, control female, treatment male and treatment female) administrated the test substance at 1000 mg/kg per rat daily for 90 days. All the animals were observed for body weight, mortality and clinical observations during the entire study. Results revealed no significant changes between the control and Fitnox treated groups. Based on the results, it was concluded that orally administered Fitnox to rats (dose of 1000 mg/kg per rat, orally-90 days) is safe with no drug-related toxicity was observed during the study period. Thus, the no-observed adverse effect level (NOAEL) for the present study is evaluated to be 1000 mg/kg body weight in both the sexes.
