Mineral relative bioavailability misconceptions explained

Availability, in absolute terms, refers to the amount of a nutrient that is available to the animal for metabolism and incorporation into tissues.

Availability, in absolute terms, refers to the amount of a nutrient that is available to the animal for metabolism and incorporation into tissues. It is extremely difficult, and often impractical, to measure absolute availability. Thus, we measure relative bioavailability, and here some confusion exists because many take this to be the same as digestibility, which it is not.
