Effects of L-theanine administration on stress-related symptoms and cognitive functions in healthy adults
Four weeks of L-theanine, the calm-focus compound in green tea, supported stress-related symptoms and verbal fluency in healthy adults.
An independent summary of published ingredient research, not the original paper or a clinical study of CORE49.
What the research found
A randomised trial explored four weeks of L-theanine supplementation in healthy adults. Researchers reported changes in some stress-related symptoms and cognitive measures.
The important context
This was a small study with multiple outcomes. The findings do not mean everyone will feel calmer; the tested dose and protocol must be considered separately from a blended formula.
Where CORE49 fits
This paper informs our understanding of an individual ingredient. It did not evaluate the finished CORE49 formula. Study populations, ingredient forms and amounts can differ from those in our daily drink; ingredient evidence and formula evidence are not interchangeable.
