Your body needs protein in large amounts daily to function property. When digested, protein is broken down into amino acids and can be used in a variety of different ways. There are 20 different amino acids that combine in different ways to make a protein.

Immune Function

When your body is under attack, such as a bacterial or viral infection, your immune system puts up a fight with proteins called antibodies. The antibodies bind to bacteria or viruses and keeps them from multiplying.

pH Balance

Your body works best if your fluid (blood, saliva, etc.) are at a neutral pH, about 7.0. However, there are many variables (what you eat, what you drink, pollution) that changes your body fluid pH. Proteins act as a shield that keeps your pH neutral. If your pH is too acidic, the protein will attract hydrogen ions until your pH is back to normal. If your pH is too basic, the protein will dump hydrogen ions.

Structure and Movement

Every single cell in your body has protein. These proteins are structural proteins; they provide the structure for your body. It is essential for hair, nails, muscles, organs, skin, ligaments, tendons and bones.


Proteins also transport nutrients. They carry sodium and potassium in and out of cells to maintain the right electrolyte balance. Proteins also carry vitamins from your organs to your cells. Hemoglobin, a specific protein found in red blood cells, carries oxygen from your lungs to your cells. Hemoglobin also takes carbon dioxide from your cells to your lungs to be released from your body when you breathe out.


These types of proteins transmits signals to coordinate biological processes between different cells, tissues and organs, such as some types of hormones.
