Arginine is an essential amino acid to children.

Essential means that the body cannot synthesize it, and therefore must be ingested through the diet.

Adults can synthesize arginine, and then it becomes non-essential.

Arginine is therefore classified as a semi-essential or conditionally essential amino acid.

Benefits Of Arginine

Arginine is a conditionally essential amino acid that has numerous functions in the body. For instance, it helps dispose of ammonia.

It can be converted into glucose and glycogen if needed. (source đź——)

Arginine is converted in the body into a chemical called nitric oxide.

Nitric oxide causes blood vessels to open wider for improved blood flow.

Arginine is also an important intermediate in the urea cycle and detoxification of nitrogenous wastes. (source đź——)
