Oral Bioavailability

Oral bioavailability refers to the extent and rate at which a substance, like a medication or nutrient, is absorbed into the bloodstream when taken by mouth. When you swallow a pill or food, it must pass through the digestive system before entering the bloodstream. Factors such as the substance's chemical properties, how it's processed in the body, and individual health can affect this absorption. Higher oral bioavailability means more of the active ingredient reaches circulation and becomes effective. Understanding this concept is important for ensuring that medications work as intended and nutrients are effectively utilized by the body.
