Why do elephants need salt?

Elephants need salt primarily for their health and physiological functions, as sodium and other minerals are essential for maintaining electrolyte balance, nerve function, and muscle contractions. In the wild, they often seek out natural salt licks to supplement their diet, as their herbivorous diet may not provide sufficient amounts of these minerals. Additionally, salt helps regulate hydration and supports overall metabolic processes. Thus, access to salt is crucial for their well-being.
