There is no single number of matcha servings that is right for everyone. The practical limit depends mainly on caffeine, serving size, personal sensitivity and other sources consumed during the day.
Count grams, not just cups
A “cup of matcha” can contain 1 gram, 2 grams, 4 grams or more. Track the weight of matcha in each drink. Tay Leaf’s latte standard uses 4 grams, while a lighter straight preparation may use about 2 grams.
Consider total caffeine
Your daily total includes coffee, tea, chocolate, energy drinks, supplements and some medications. For most healthy adults, total caffeine up to about 400 milligrams per day is generally not associated with negative effects, but this is not a target and individual tolerance can be much lower.
Signs to reduce your intake
- Restlessness or shakiness
- Anxiety or a rapid heartbeat
- Stomach discomfort
- Headaches
- Trouble falling or staying asleep
People who need individualized guidance
Pregnant or breastfeeding people, children, people taking certain medications, and anyone with a condition affected by caffeine should follow guidance from an appropriate healthcare professional.
A practical approach
Start with one measured serving, observe how you feel, and avoid increasing several variables at once. If you make lattes, use the standard preparation guide so the dose remains consistent.
