Question

Quizplus · Accepted Answer

The bioavailability of dietary zinc varies depending on the source, but typically ranges from 15-40 percent. This means that only a portion of the zinc consumed is actually absorbed and utilized by the body. Zinc from animal products (meat, fish, poultry) is more readily absorbed than zinc from plant sources (such as grains and legumes). Adequate intakes of protein, vitamin A, and other minerals like iron and calcium can also improve zinc absorption.
