Research review
Does ginger root tea have caffeine?
Ginger root itself is not a source of caffeine and contains none — its documented active compounds are gingerols and shogaols, not a stimulant. The evidence doesn't support ginger changing how caffeine affects the body, because no trial has tested the two together.
The evidence doesn't support ginger root as a source of caffeine, and it doesn't support any claim that combining ginger with caffeine changes how caffeine affects the body — no trial has tested that pairing. Ginger root itself contains no caffeine; its documented active compounds are gingerols and shogaols, not a stimulant.
What the evidence doesn't support
It doesn't support the idea that ginger is a caffeine source, that it "boosts" caffeine's effects, or that it offsets caffeine's downsides like jitteriness or a crash. None of those pairings have been tested in a human trial. A search for "ginger and caffeine" often turns up recipes and marketing for energy drinks or pre-workout blends that include both ingredients, but a product containing both isn't the same as research showing they interact.
What's actually documented about ginger's composition
A National Institutes of Health reference database identifies gingerols and shogaols as ginger's characteristic pungent compounds, and describes it as commonly used for nausea and motion sickness — not as a stimulant, and not alongside any mention of caffeine content. Caffeine is a specific, well-studied compound found naturally in coffee beans, tea leaves, cacao and kola nut. Ginger root doesn't belong to any of those plant families and isn't reported to contain caffeine in USDA food composition data or the pharmacology literature reviewed for this site. Separately, ginger has documented effects on gastric emptying and platelet function (covered in ginger benefits: what the research does and doesn't show and ginger and medications: what to check) — real, measured effects, but unrelated to caffeine or stimulation.
That said, a bottled "ginger tea," "ginger root beer," or ginger-flavored drink can contain caffeine if the manufacturer blends in real tea leaves, coffee, guarana or another caffeinated ingredient — that caffeine comes from the added ingredient, not from the ginger itself. The only reliable way to know is to check that specific product's label or ask the manufacturer, since recipes vary and this page can't speak to any one brand's formulation.
Questions people ask
Does ginger root tea have caffeine?
Plain ginger tea, made from fresh or dried ginger root steeped or simmered in water, does not naturally contain caffeine. A blended product that adds tea leaves, coffee or another caffeinated ingredient would, but that's a matter of what else is in the recipe.
Does ginger root have caffeine?
No. Ginger root's documented active compounds are gingerols and shogaols, not caffeine or a related stimulant.
Do ginger sodas have caffeine?
It depends on the specific product and its full ingredient list — some brands make caffeine-free versions and others don't, and ginger itself isn't the ingredient that would add it. Check the can or bottle's label for that product.
Is ginger root extract caffeine-free?
A ginger extract made from the root itself contains no caffeine. If it's combined with other botanicals in a blended supplement, check that product's full ingredient list rather than assuming based on the word "ginger" alone.
When to talk to a doctor
Ginger is not a substitute for caffeine, a treatment for fatigue or low energy, or a way to change how caffeine affects you — none of that is supported by the research reviewed here. If you're managing caffeine intake for a health reason, or have questions about how any supplement fits alongside your diet or medication, ask a doctor.
