Alertness / attention (acute)

Limited Evidence

Small acute studies of standardized Alpinia galanga extract report effects on sustained attention, comparable in scale to mild stimulants.

How it works

Galangal rhizomes contain volatile oils, gingerols-related diarylheptanoids, and flavonoids (galangin). Preclinical work suggests anti-inflammatory, antioxidant, and antimicrobial activity, and some small studies have explored effects on alertness and respiratory comfort. Human clinical evidence is most developed for branded Alpinia galanga standardized extracts (e.g., 'EnXtra') with small trials suggesting acute effects on attention.

Dosage

There is no RDA. Branded extracts have been tested at around 300 mg. Traditional culinary use is small. DSLD does not provide a median dose for this entry.

When and how to take it

Standardized extracts marketed for alertness are typically taken in the morning. Take with food to reduce GI upset.
