Optimum Dose - GCSE Biology Definition

Reviewed by: Lára Marie McIvor

Last updated

The term 'optimum dose' refers to the amount of a substance, such as a medicine or nutrient, that produces the best effect with the fewest side effects. In biology and medicine, finding the optimum dose is important to ensure the treatment is both effective and safe. A dose that is too low may not work, while a dose that is too high could cause harmful side effects. Scientists and doctors test to find this balance when developing medicines or treatments.
