Matcha and Immune Support
Matcha contains catechins, especially EGCG, which have antioxidant properties. A 2018 review in Nutrients notes that green tea polyphenols may support immune function. However, matcha is not a treatment or cure for illness.
Potential Benefits When You Are Sick
Warm matcha can soothe a sore throat and provide mild hydration. It also contains L-theanine and a small amount of caffeine, which may help with alertness without the jittery effect of coffee. Matcha may ease mild fatigue when you are recovering from a common cold.
When to Avoid Matcha While Sick
Avoid matcha if you have nausea, acid reflux, or a sensitive stomach, because it can increase stomach acid. Its caffeine content may interfere with sleep, which is important for recovery. If you are taking medication, check with a healthcare provider, as tannins in matcha can reduce absorption of some drugs.
