Adaptogen drinks, lattes and coffee alternatives checked: how much caffeine is typical, what a drink label may hide, and the few studies that tested an adaptogen drink.

Safety first. Natural products can cause side effects and interact with medicines. Read who should be careful, by situation before you use anything on this page.
Adaptogen drinks include ready-to-drink bottles, powders stirred into a latte, "mushroom coffee" and coffee alternatives. The claims are usually about calm focus or steady energy. This page asks what is known about the drink itself. "Adaptogen" is a contested term, not a medical category (see what adaptogens are), and no brands are named here.
Before you start. This is information, not medical advice. If you take medicines, are pregnant or breastfeeding, or are sensitive to caffeine, ask a pharmacist or clinician first. In the US, call or text 988 if low mood or anxiety is affecting your daily life; a drink is not a treatment.
Start with the caffeine
Many functional drinks contain caffeine, and caffeine is the one effect that is well documented. The FDA cites 400 mg a day, about two to three 12-ounce cups of coffee, as an amount not generally associated with negative effects for most adults, and adds that sensitivity and how fast people clear caffeine vary widely. [1]| 12-fluid-ounce drink | Typical caffeine per the FDA |
|---|---|
| Green tea | 37 mg |
| Black tea | 71 mg |
| Regular brewed coffee (non-specialty) | 113 to 247 mg |
| Energy drink | 41 to 246 mg |
[1] The FDA also says decaffeinated coffee and tea still contain some caffeine, and that caffeine from added sources is handled by the body the same way as caffeine from coffee or tea. [1]
Reading the label: packaged foods that contain added caffeine must list it as an ingredient, and many give the amount voluntarily, but restaurants and cafes are not required by law to tell you how much caffeine is in what they serve. [1] Ask the retailer. For pregnancy or breastfeeding, the FDA recommends talking to a health care provider about limiting caffeine. [1] For children and teens, medical experts advise against energy drinks because of sugar and caffeine. [1]
What an "adaptogen" adds is not clear from labels
A 2022 analysis of 75 top-selling US energy drinks and shots (55 drinks, 20 shots) found 15 products with proprietary blends that hid individual ingredient amounts, and every product contained caffeine (average 174.4 mg). [2] The study did not set out to measure adaptogens, so it does not tell us how much ginseng or any adaptogen those products held. A proprietary blend is a legal way to list a total without individual amounts; see proprietary blends and reading labels.What research has tested in drinks
| Question | What the source found | Strength of evidence |
|---|---|---|
| Does one caffeinated adaptogen-containing shot differ from a caffeine-only shot? | A crossover trial in 30 adults who were low caffeine consumers compared such a shot, a matched caffeine shot and placebo. Both caffeinated drinks raised systolic blood pressure at 30 minutes (still within normal healthy ranges), and the authors suggested the adaptogen blend might modulate caffeine's effect on mood and thinking. [3] | Promising but limited: one small trial of one product; the effect of any single herb cannot be separated. We did not read funding. |
| Do adaptogen lattes or powders improve stress, energy or focus? | Proper evidence not found. We read no trial of a latte or powder drink. | No usable evidence |
| Does mushroom coffee do what is claimed? | Proper evidence not found. A PubMed search for "mushroom coffee" returned no human study of it. | No usable evidence |
For mushroom coffee and blends specifically, see mushroom coffee and adaptogen blends, claims checked. Mushroom guides: reishi and cordyceps.
Frequently asked questions
Is adaptogen coffee healthier than regular coffee?
Proper evidence not found. We read no comparison. If the drink contains coffee, the FDA's caffeine figures apply. [1]
How much caffeine is in an adaptogen latte?
It depends on the base. Brewed coffee typically has 113 to 247 mg per 12 fluid ounces; cafes are not required to state caffeine. [1] Ask the seller.
Does mushroom coffee reduce stress?
Proper evidence not found in our PubMed search. See the linked claim-check page for the mushroom side.
Can I have these drinks while pregnant?
The FDA advises talking to a health care provider about limiting caffeine in pregnancy and breastfeeding. [1] We read no safety data on the adaptogen ingredients in drinks.
Are these drinks safe for teenagers?
Medical experts advise against energy drinks for children and teens. [1] See adaptogens for children and teenagers.

Safety questions to ask
- Is the adaptogen one with known cautions? NIH says insomnia is the most common side effect of Asian ginseng. [4] A drink that adds a stimulant herb to caffeine has not been shown, in the sources we read, to be gentler.
- Which medicines do you take? See how medicine interactions work and adaptogen medicine interactions.
- Is the drink replacing sleep or a clinician visit? A persistent need for stimulants is a reason to see a clinician. See adaptogens vs caffeine and other stimulants and caffeine and energy drinks.
