The human body requires a constant supply of amino acids for protein synthesis and other metabolic processes. This process is not passive; it relies on complex and specialized transport systems to ensure these vital building blocks are moved efficiently from the diet and across cellular membranes.

While it's a common misconception that all proteins and their fragments must be fully broken down into single amino acids, research shows that dipeptides and tripeptides are absorbed intact across the intestinal wall. So, do peptides need to be digested for the body to use them effectively? The process is more complex and depends heavily on the peptide's size and structure.

Over 95% of ingested protein is effectively digested and absorbed in the small intestine. A key question in nutrition is: **Does amino acid need to be digested before absorption?** The answer reveals a more complex and efficient process involving the uptake of various protein fragments, not just individual amino acids.
