Nutritional Profile
A standard 2g serving of matcha powder typically contains:
- 5 calories
- 0.3g protein
- 0.8g carbohydrates
- 0.8g dietary fiber
- Key vitamins and minerals:
- Vitamin A (β-carotene): approximately 580μg
- Vitamin C: about 1mg
- Vitamin K: around 58μg
- Potassium: about 54mg
- Calcium: approximately 8mg
Potential Brain Function and Cognitive Effects
Recent clinical trials suggest matcha may influence brain function. The combination of caffeine (64mg) and L-theanine(27-53mg) per serving might contribute to:
- Possible enhancement of attention and memory performance
- Potential improvements in emotional perception
- Suggested benefits for social cognition, particularly observed in older adults
A 12-month randomized, double-blind, placebo-controlled study with 99 participants indicated potential cognitive benefits, particularly regarding social cognition.
Sleep Quality
Some research suggests matcha might improve sleep quality, particularly in older adults with mild cognitive decline. However, timing of consumption may affect individual sleep patterns.
Antioxidant Content
Research indicates matcha may have notable antioxidant content:
- Studies suggest it contains more catechins than regular green tea
- Contains epigallocatechin gallate (EGCG), an antioxidant compound
- May provide concentrated nutrients due to consuming the entire leaf
Cardiovascular Health
Studies suggest possible cardiovascular effects:
- Some research indicates possible reduction in heart disease risk
- May influence blood pressure
- Potential effects on LDL cholesterol levels
Safety and Consumption Considerations
Current evidence suggests these guidelines:
- Contains approximately 64mg caffeine per serving
- Pregnant women may want to consult healthcare providers about intake
- Consider avoiding late-day consumption if sensitive to caffeine
- Discussing potential medication interactions with healthcare providers may be beneficial
While research on matcha tea continues to evolve, current scientific evidence suggests it may be a beneficial addition to a balanced diet. Consider the quality and timing of consumption while being mindful of individual caffeine sensitivity.
