There are some Coca-Cola drinks which do contain protein but at very small amounts, due to the sweetener aspartame.

Aspartame is made up of two amino acids, aspartic acid and phenylalanine. It is a sugar alternative, used in place of sugar in many foods and drinks to provide people with a reduced, low or no sugar and kilojoule option.

The Classic Coca-Cola formula does not contain any protein. Coca-Cola Vanilla and Coca-Cola with Stevia also do not contain any protein.

The Coke No Sugar, Diet Coke and Coke Zero products have trace levels of protein. The 250ml can of Coke No Sugar contains 0.13 grams of protein while the standard 375ml can of Diet Coca-Cola contains 0.19 grams of protein.
