A carbohydrate supplement helps replace the muscle glycogen lost from your workout. Glycogen is the primary source of fuel your muscles use for energy production, therefore, is critical for performance.

2. Are carbohydrates supplements safe?

Carbohydrate powder supplies your body with energy, but this can be detrimental in some cases, as it may cause your body to burn less stored energy.

Carbohydrate Source and Properties Many of the best carbohydrate supplements use dextrose, maltodextrin, or waxy maize as their source—others are extracts from vegetables such as potatoes or rice.

4. What is the function of carbohydrate supplements?

Energy. The primary function of dietary carbohydrate in ONS and other food products is to provide an energy source. Carbohydrate delivers roughly 4 kcal per gram, which is a slightly greater level of energy than delivered by protein and roughly half the calories per gram delivered by fat [47].
