Quizplus · Accepted Answer

Bioavailability is the fraction of a nutrient that is absorbed and used by the body. In this case, the bioavailability of the vitamin is 35%, which means that only 35% of the vitamin that Brian consumes is actually absorbed and used by his body. Therefore, Brian needs to consume 100 milligrams / 0.35 = 285.71 milligrams of the vitamin each day to meet his needs.
