TheaRelax™
The Fermented Relaxation Extract
A unique fermented green tea extract from Fermedics, standardized for L-theanine, a compound clinically studied for its benefits on stress-management, cognitive performance and sleep quality.

What is TheaRelax™ Good For?
TheaRelax™ provides a natural source to help anxiety management and sleep without causing drowsiness. By using fermentation technology, Fermedics enhances the purity and bioavailability of L-theanine.
TheaRelax™ supplementation may lead to:
- Improved stress and anxiety management
- Enhanced cognitive performance and memory in people with mild-cognitive impairment
- Improved overall sleep quality by helping to fall asleep more easily and reducing sleep disturbances
- Reduction in triglyceride levels (as demonstrated in animal models)
- Reduced risk of obesity through induced serotonin production (as demonstrated in animal models)
- Improved glucose tolerance and fatty liver markers (as demonstrated in animal models)
- Reduced inflammatory markers of IL-6 and TNF-alpha (as demonstrated in animal models)
- Improved gut microbiome ratios by increasing species from Bacteroidota phylum, which is associated with lowered obesity risks (as demonstrated in animal models)
- Improved antioxidant effects through increased superoxide dismutase and glutathione peroxidase (as demonstrated in animal models)
What is TheaRelax™?
TheaRelax™ is a fermented green tea extract designed to deliver a highly bioavailable form of L-theanine, the amino acid responsible for tea’s calming effect. Fermentation improves purity and enhances additional bioactive compounds.
Unlike synthetic L-theanine, TheaRelax™ provides a natural source, while fermentation improves concentration of L-theanine and other bioactives.
What is the Recommended Daily Dose of TheaRelax™?
Human clinical research supports 200 mg daily L-theanine for stress management, cognitive performance, and improving sleep quality, the dosage also validated in TheaRelax™ applications.
