Carbohydrates are one of the body’s three natural energy sources along with proteins and fats. Carbohydrates are often cited as a natural source of physical energy, but they also provide mental energy to the brain. Their function does not stop here - many types of carbohydrates also contain fibre, which maintains healthy metabolism and bowel movements.

Carbohydrate supplements perform a variety of functions and come in a range of forms. They are predominantly used by athletes and strength trainers for energy or by people aiming to gain weight.
