green tea extract

Botanical

Green tea extract brings catechin antioxidants and two footnotes worth knowing: caffeine status and the high-dose liver literature — neither at label doses.

Also appears on labels as: green tea · decaffeinated green tea extract · camellia sinensis extract

What it is

Extract of Camellia sinensis leaves, standardized for catechins (EGCG). Pet-food versions are typically decaffeinated — worth confirming on the label, since caffeine is genuinely toxic to dogs and cats. Human and canine research on concentrated high-dose EGCG has flagged liver stress, particularly fasted; food-level inclusions sit far below those doses.

Why it's in pet food

Antioxidant positioning with a modern-wellness accent. At recipe doses the honest description is 'a polyphenol garnish' — present, plausible, and unmeasurable from the outside.

How Bowlmark scores it

Scores are deterministic math over the printed label — the rules below apply to every product identically, and nothing estimates or fills in a blank.

Neutral: no bonus, no deduction, no flag. The two footnotes are context, not points: 'decaffeinated' on the label is the version to prefer, and the high-dose EGCG liver literature is a supplement-aisle concern that food inclusions don't approach. Caffeinated tea and coffee themselves belong nowhere near pets.

For dogs

The caffeine hazard is the household one — tea bags, coffee grounds, espresso beans. The decaffeinated extract in a recipe is a different exposure by orders of magnitude.

Common questions

Answers come from this entry and the scoring rules above — reviewed before publish, like everything else on this page. For anything about your own pet, your vet knows best.

Is green tea extract safe for dogs?

At recipe doses, the honest description is "a polyphenol garnish" — present, plausible, and far below the concentrated high-dose EGCG amounts the liver-stress literature flags. Pet-food versions are typically decaffeinated — worth confirming on the label, since caffeine is genuinely toxic to dogs and cats.

Can dogs have caffeine from green tea?

No — caffeine is genuinely toxic to dogs and cats, and the household hazard is the real one: tea bags, coffee grounds, espresso beans. The decaffeinated extract in a recipe is a different exposure by orders of magnitude; caffeinated tea and coffee themselves belong nowhere near pets.

How does Bowlmark score green tea extract?

Neutral: no bonus, no deduction, no flag. The two footnotes are context, not points: "decaffeinated" on the label is the version to prefer, and the high-dose EGCG liver literature is a supplement-aisle concern that food inclusions don't approach.
