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.

Approximately 98% of small-molecule drugs fail to cross the blood-brain barrier (BBB), but many vital nutrients, including specific amino acids, successfully navigate this biological defense. Understanding which amino acids cross the blood-brain barrier is crucial for appreciating the brain's metabolic needs and its communication with the rest of the body.
