Research review
Does turmeric have caffeine?
Turmeric root doesn't contain caffeine; it's a rhizome, not a caffeine-producing plant like coffee or tea. No trial has tested turmeric or curcumin combined with caffeine specifically, so claims about the pairing boosting energy or absorption go beyond what's been measured.
Turmeric doesn't contain caffeine. It's a rhizome from the ginger family, not a caffeine-producing plant like coffee or tea, and USDA FoodData Central's nutrient listing for turmeric doesn't include any. What hasn't been studied is whether combining turmeric or curcumin with caffeine — in a "golden coffee," a latte, or a supplement stack — does anything beyond what each ingredient does on its own.
What the evidence doesn't support
It doesn't support the idea that turmeric contains any caffeine of its own, and it doesn't support a specific claim about combining turmeric with caffeine — for energy, absorption or anything else — because no trial has tested that combination directly.
What the trials found
There's no caffeine content to report for turmeric root or a curcumin extract; it's a food-composition fact, not a research finding, and USDA FoodData Central is the reference for it.
The actual research on raising curcumin's absorption is about a different pairing. Curcumin is well documented to absorb poorly on its own — a 2007 pharmacokinetic review describes poor absorption, rapid metabolism and rapid elimination as its central limitation. A 1998 human trial found that a 2 g dose of curcumin taken alone was barely detectable in blood, but adding 20 mg of piperine (from black pepper) raised curcumin's measured bioavailability by 2000%. That's the pairing with actual human pharmacokinetic data behind it — piperine, not caffeine. No trial has tested whether caffeine has any similar effect on curcumin absorption, or whether curcumin changes how caffeine is absorbed or metabolized.
Questions people ask
Does turmeric tea or turmeric latte have caffeine?
Only if it's made with an ingredient that does. Turmeric root and powder contain none; a golden latte made with black tea or added coffee gets its caffeine from that ingredient, not the turmeric. See turmeric tea for what plain turmeric tea does and doesn't contain.
Can you take a turmeric supplement with coffee?
No documented interaction has been reported between turmeric or curcumin and caffeine at typical intake amounts. For the practical side of timing turmeric around coffee, including one small study on turmeric and mineral absorption from a meal, see turmeric and coffee.
Does caffeine help turmeric absorb better?
No trial has tested that. Piperine is the absorption enhancer with human pharmacokinetic data behind it; caffeine hasn't been studied for that purpose.
When to talk to a doctor
If caffeine itself affects you strongly, or your doctor has asked you to limit stimulants, that's a caffeine question, not a turmeric one — turmeric itself contributes none. If you take medication, or are pregnant or nursing, talk to a doctor before adding any supplement.

- Bioavailability of curcumin: problems and promises A 2007 review found curcumin is safe at doses up to 12 grams a day in early human trials but absorbs poorly on its own, which is why supplements pair it with piperine, a phospholipid complex, liposomes or nanoparticles to raise how much reaches the bloodstream.
- Influence of piperine on the pharmacokinetics of curcumin in animals and human volunteers A 1998 study found 2 g of curcumin taken alone barely showed up in human blood at all, but adding just 20 mg of piperine (from black pepper) increased how much curcumin reached the bloodstream by 2000%.
