Which type of protein contains all 9 essential amino acids?

Complete protein is the term used to describe proteins that provide all nine essential amino acids that the human body cannot synthesize on its own. Essential amino acids are vital for various bodily functions, including tissue repair, hormone production, and the maintenance of a healthy immune system.

Foods that are classified as complete proteins typically include animal sources such as meat, poultry, fish, eggs, and dairy products, as well as some plant-based sources like quinoa and soy. Consuming complete proteins ensures that the body receives a balanced intake of all necessary amino acids, which is crucial for overall health and wellness.

In contrast, partial or incomplete proteins do not contain all essential amino acids in the required amounts, making them inadequate on their own for supporting all the amino acid needs of the body. Supplemental protein refers to protein products added to diets, which may or may not provide complete amino acid profiles depending on their source.
