Root Explanation

Bioavailability → It is formed from "bio-" (from Greek "bios", meaning life) and "availability" (from Latin "valere", meaning to be strong or to be worth). The term refers to the extent and rate at which the active ingredient or active moiety is absorbed and becomes available at the site of action in the body, thus relating to how life processes utilize substances.

Memory Tip

Think of 'bio-' meaning 'life' and 'availability' indicating how much of something is accessible — bioavailability describes how much of a substance is available for life processes.
