Oral β-alanine absorption kinetics and muscle carnosine synthesis in the human vastus lateralis

Read the original on PubMed 16554972
Plain-language summary

The foundational human pharmacokinetic study that mapped how oral β-alanine is absorbed, distributed, and ultimately incorporated into muscle carnosine over weeks of supplementation. The data established β-alanine — not carnosine itself — as the rate-limiting substrate for raising intramuscular carnosine, and set the dosing logic the field still uses today.

Key takeaways
  • β-alanine is the limiting substrate for muscle carnosine synthesis.
  • Defined the dose, frequency, and duration of modern loading protocols.
  • Cited in essentially every subsequent β-alanine trial.
