# Setting the Stage for Branched-Chain Amino Acids Use in Neurological Pathologies: Does a Single Oral Dose Provide Hours of Elevated Systemic Levels?

## TL;DR

This study shows that a single dose of branched-chain amino acids can significantly raise their levels in the blood for hours, which may help in treating brain injuries.

## Contribution

The study provides the first evidence of sustained elevated branched-chain amino acid levels after a single oral dose in healthy adults.

## Key findings

- Branched-chain amino acid levels remained significantly elevated compared to baseline.
- A single oral dose is a viable method to increase systemic branched-chain amino acid levels.
- The findings support the potential use of branched-chain amino acids in neurological treatment planning.

## Abstract

Background: Recent studies have demonstrated that branched-chain amino acids are neuroprotective and neurorestorative. Branched-chain amino acid supplements are now being recommended to be taken before contact sports to reduce concussions. While peaks and troughs in branched-chain amino acids have previously been reported in hospital settings, the metabolism of a single recommended dose of over-the-counter branched-chain amino acids has yet to be elucidated. Methods: We analyzed a patented branched-chain amino acid product to assess its metabolism in 10 healthy adults. Results: Over the defined time points, measured levels of branched-chain amino acids remained significantly elevated when compared to the physiological baseline. The elevations in measured plasma levels indicate that a single oral dose is a viable intake option for increasing levels of branched-chain amino acids. Conclusions: This information can be leveraged to better plan branched-chain amino acid-based treatment doses in order to treat pathologies such as brain injury.
