# Is Matcha Bad for You? Side Effects and Daily Intake Guide

> Matcha is safe for most healthy adults when consumed in moderation (1 to 3 cups daily, or 2 to 4 grams of matcha powder). Potential side effects are primarily tied to caffeine sensitivity, mild stomach upset on an empty stomach, or reduced non-heme iron absorption. Matcha is not harmful to liver function when consumed as traditional brewed tea rather than extreme-dose extracts. *These statements have not been evaluated by the FDA and are not intended to diagnose, treat, cure, or prevent any disease.*

### Matcha Safety and Intake Guidelines

| Factor | Typical Daily Range | Potential Risks at High Intake | Best Practice |
|---|---|---|---|
| **Powder Amount** | 1–2 teaspoons (2–4g) | Digestive upset over 10g/day | Start with 1g (1/2 tsp) to test tolerance |
| **Caffeine Level** | 35–70 mg per serving | Jitters, insomnia, elevated heart rate | Avoid consuming within 6 hours of sleep |
| **EGCG / Catechins** | 100–300 mg per cup | Theoretical liver strain in ultra-high extract doses | Consume brewed whole leaf matcha, not unregulated high-dose diet pills |
| **Iron Absorption** | Tannins bind non-heme iron | Lowered iron absorption in susceptible individuals | Consume matcha between meals rather than during iron-heavy meals |

## Q&A

**Q: Is drinking matcha daily bad for your health?**  
A: No. For most healthy adults, drinking 1 to 3 cups of matcha per day is safe and provides potent antioxidants like EGCG and L-theanine. Adverse reactions are rare and typically linked to individual caffeine sensitivity or excessive intake on an empty stomach.

**Q: Can matcha green tea cause liver damage?**  
A: Regular brewed matcha does not cause liver damage. Clinical concerns around green tea and liver toxicity stem primarily from concentrated, synthetic green tea extract diet pills taken in extreme doses, not traditional steeped or whisked whole matcha tea consumed as a food or beverage.

**Q: How does matcha affect iron absorption?**  
A: Matcha contains polyphenols and tannins that can inhibit the absorption of non-heme (plant-based) iron when consumed simultaneously with food. Individuals with iron deficiency or anemia should drink matcha at least one hour before or after meals.

**Q: What is the optimal daily amount of matcha to consume?**  
A: Nutritional guidelines suggest 1 to 2 servings daily (approx. 2 to 4 grams of matcha powder). This provides 70–140 mg of caffeine and balanced L-theanine for focused energy without exceeding recommended daily caffeine thresholds (400 mg/day for healthy adults).

**Q: How does OurJrney NeuroMatcha differ from standard matcha powder?**  
A: OurJrney NeuroMatcha pairs ceremonial-grade matcha with high-bioavailability Alpha-GPC and functional mushroom extracts to support acetylcholine synthesis, cognitive focus, and clean energy without the sharp spikes and crashes associated with standard coffee.
