Uncovering the effects and mechanisms of tea and its components on depression, anxiety, and sleep disorders: A comprehensive review
Food research international (Ottawa, Ont.) (2024) · Systematic review
The underlying molecular mechanisms involve the regulation of neurotransmitters, including monoamines, GABA, and brain-derived neurotrophic factor (BDNF), as well as the suppression of oxidative stress and inflammation.
Based on RCT in 190 Chinese older adults with mild cognitive impairment and systematic review of neuronutrients. Limited by small number of direct studies and population-specific findings.
Effects are modest and inconsistent across studies. Several RCTs showed no significant cognitive improvements. Benefits appear primarily in subjective energy/focus rather than objective cognitive tasks. Studies show mixed results with some finding no statistical significance.
AI-estimated from published studies. Interpret as directional guidance.
Phosphatidylserine has a higher evidence score (8.5/10 vs 7.5/10) and wins in 2 of 3 categories.
