Bioavailability of Amino Acids

Meaning

Bioavailability of Amino Acids quantifies the proportion of ingested amino acids that are effectively absorbed from the gastrointestinal tract and become available for systemic utilization, including protein synthesis, hormone production, and neurotransmitter generation. This metric is a critical determinant of nutritional efficacy, as it reflects the true metabolic impact of a dietary protein source or supplement. Factors such as digestion rate, transport capacity, and first-pass hepatic metabolism significantly influence this crucial physiological parameter.
