How Protein Powder Ingredients Are Made

Protein powder ingredients go through multiple steps before they appear as finished products. These steps are designed to separate protein from raw food sources and prepare it for consistent use in...

Amino Acids and Protein Quality

Protein quality is often discussed at a high level, but at its foundation, protein quality is closely tied to amino acids. Because proteins are built from amino acids, the presence, balance, and av...

Amino Acids in Plant and Animal Proteins

Proteins from both plant and animal sources are made from amino acids. While these sources differ in origin and composition, the body ultimately breaks all dietary protein down into amino acids and...

Amino Acids and Nutrient Transport

After amino acids are absorbed into circulation, they must be transported to cells throughout the body. Nutrient transport is the system that moves amino acids and other nutrients from the bloodstr...

Amino Acids and Protein Absorption

After protein is digested into amino acids and small peptide units, absorption is the step that allows those components to enter circulation. Protein absorption determines whether digested amino ac...

Amino Acids and Protein Digestion

Protein digestion is the process that breaks dietary protein down into amino acids so they can be absorbed and used by the body. Amino acids are not present in usable form until this digestion proc...

Amino Acids and Digestive Health

Digestive health refers to how well the digestive system carries out its normal functions. Amino acids are part of this picture because they are the end products of protein digestion and must pass ...

Amino Acids and Digestive Efficiency

Digestive efficiency describes how effectively amino acids move through digestion and absorption to become available for use inside the body. It does not describe outcomes or results. Instead, it r...

Amino Acids and Digestive Absorption

Digestive absorption is the step that allows amino acids to move from the digestive tract into the body’s internal circulation. While digestion breaks protein down into smaller components, absorpti...

How Amino Acids Are Absorbed

After protein is digested, amino acids must be absorbed before the body can use them. Absorption is the step that moves amino acids from the digestive tract into circulation, where they become avai...
