Frequently Asked Questions
What is theanine?▼
Theanine is a phytochemical that accumulates in Camellia sinensis (tea plant) and has demonstrated neuroprotective effects.
How does theanine affect sleep?▼
Theanine alleviates neuroinflammation, which helps treat mild sleep disturbances caused by cumulative stress.
Is theanine effective for depression from sleep deprivation?▼
Yes, the abstract states theanine has therapeutic effects on depression induced by sleep deprivation.
What other health benefits does theanine have?▼
It also shows beneficial effects in delaying progression of neurodegenerative diseases like Parkinson's and Alzheimer's, and protects against organ dysfunction from nerve injury.
