A single-dose acute oral toxicity produced no toxic effects after 14 days of treatment. Four-week (subacute) and 3-months (subchronic) oral toxicity studies were conducted and observed no abnormal clinical signs, no alterations in the body weight, hematology and biochemical parameters or gross and histopathological changes. Thus, oral administration of LivLonga showed no signs of toxicity when dosed orally to rats, with a no observed adverse effect level (NOAEL) of 600 mg/kg/day.
