Is Matcha Safe for Dogs and Cats?
Green tea, especially Matcha, is well-known for its health benefits in humans, but what about our furry friends? Many pet owners wonder whether introducing green tea or Matcha into a dog’s or cat’s diet is safe and beneficial. In this article, we explore the scientific evidence, potential benefits, and precautions for giving green tea to pets.
Why Green Tea Is Popular in Pet Health
Green tea contains polyphenols, namely catechins, particularly epigallocatechin gallate (EGCG), known mainly for its antioxidant and health-promoting properties. While humans consume it daily with our cup of tea, research shows that pets can also benefit-if administered in safe doses.
Benefits of Green Tea for Dogs and Cats
1. Oral Health
- EGCG and other catechins help reduce gum inflammation.
- Can prevent periodontal disease, common in dogs.
2. Metabolism and Weight Management
- In overweight dogs, EGCG can improve insulin sensitivity.
- Supports healthy glucose and lipid metabolism.
3. Natural Food Preservation
- Antioxidants in green tea stabilize fats in pet food.
- Extends shelf life while maintaining quality and natural appeal.
4. Joint Support and Pain Reduction
- Diets enriched with green tea extract, curcumin, and collagen can reduce arthritis-related pain in dogs.
- Improves mobility and overall quality of life.
5. Anti-Cancer Properties
- Polyphenols in green tea can inhibit all stages of cancer development.
- EGCG protects DNA, scavenges free radicals, and inhibits enzymes linked to tumor growth.
6. Skin and Coat Health
- EGCG supports healthy skin and fur, helping with hair loss and dermatological issues.
- Can be used in green tea-infused shampoos or baths.
7. Stress Reduction and Behavior Improvement
- L-theanine in Matcha (an amino acid existing in large quantities) helps reducing anxiety, fear, and aggression in cats and dogs.
- Contributes to the increase of serotonin and dopamine levels, improving mood, behavior, and sleep.
Safety Guidelines: How Much Green Tea or Matcha Is Safe for Pets
Caffeine Concerns
Green tea contains caffeine, which is toxic in high doses.
Lethal dose (MLD50) in dogs: ~140 mg/kg (range 120–200 mg/kg).
Examples:
10 kg dog → 1,200-2,000 mg caffeine can be dangerous.
1 g Matcha → 18-35 mg caffeine; 1 cup green tea (~250 ml) → 30-50 mg.
Recommended Dosage Based On Research
No more than 1 g of Matcha per day for dogs or cats.
Always dilute with water.
EGCG: Fasted dogs are sensitive to doses >40 mg/kg/day; fed dogs can tolerate up to 500 mg/kg/day.
