Probably some, yes. The Audifort blend includes guarana seed extract and green tea leaf extract. According to the FDA, guarana is one of the ingredients that can carry caffeine, and NCCIH says green tea contains it. What you won't find on the bottle is a number: there is no caffeine line on the label, so you can't tell how much a dropper adds to your day.
Why the word caffeine isn't on the label
The FDA explains how this works for packaged foods. When an ingredient naturally contains caffeine, the label names that ingredient and caffeine itself doesn't appear in the list. Chocolate is the FDA's example. Audifort's label follows the same pattern. Inside the 200 mg proprietary blend you'll find "Guarana (Paullinia cupana) Seed Extract" and "Green Tea (Camellia sinensis) Leaf Extract", and nowhere does it give a caffeine figure.
The FDA also notes that many drinks and supplements containing caffeine state the amount on the label voluntarily. The word it uses is voluntarily, so Audifort isn't breaking a rule by leaving it off. It does leave caffeine-sensitive buyers guessing.
For context, the order page credits green tea with supporting blood flow to the ears. That's the seller's claim, and the caffeine that comes with the leaf is a separate matter.
How much caffeine could one dropper hold
There's exactly one hard number to work with. A dropper is 1 ml, and the entire blend in that milliliter weighs 200 mg. Whatever caffeine the guarana and green tea bring is part of those 200 mg. So the caffeine in one dropper can't be more than 200 mg.
Read that as a ceiling, nothing more. To reach it, the whole blend would have to be pure caffeine, and it can't be, because the same 200 mg also holds maca, ginseng, eight amino acids and the rest of the 22 ingredients. The real amount is likely far lower. The label gives no way to say how much lower.
Example, assuming the impossible case that the entire blend were caffeine:
| Daily amount | Blend weight | Caffeine ceiling (example) | Ceiling as a share of the FDA's 400 mg |
|---|---|---|---|
| 1 dropper (order page directions) | 200 mg | 200 mg | 50% |
| 2 droppers (top of the label's directions) | 400 mg | 400 mg | 100% |
The table is only useful as an outer limit. It does not mean Audifort contains 200 or 400 mg of caffeine.
What the FDA says about 400 mg a day
For most adults, the FDA has cited 400 mg a day, roughly two to three 12-ounce cups of coffee, as an amount not generally associated with negative effects. The same page stresses how much people differ in sensitivity and in how quickly they clear caffeine, and says some medical conditions and medications make people more sensitive.
The part most relevant to Audifort is the FDA's advice to count every source. Your body handles caffeine from a plant ingredient the same way it handles caffeine in coffee or tea. If you already drink a few cups a day, a dropper adds an unknown amount on top, and the chart below shows how quickly ordinary drinks use up that 400 mg.
FDA figures for common drinks. Where the FDA gives a range, the bar runs to the top of it. Audifort is not on the chart because its label gives no caffeine amount.
| Drink | Caffeine |
|---|---|
| Green tea | 37 mg |
| Black tea | 71 mg |
| Caffeinated soft drink | 23 to 83 mg |
| Energy drink | 41 to 246 mg |
| Coffee, regular brewed | 113 to 247 mg |

Who should be careful with an unlisted amount
The FDA's general tip for a new product with added caffeine and no declared amount is to take care the first time you try it. Audifort's caffeine comes from plant extracts rather than added caffeine, but the same care makes sense for these readers:
- People who react strongly to caffeine or have been told to cut back.
- Anyone pregnant, trying to get pregnant or breastfeeding. The FDA suggests asking a provider about caffeine, NCCIH says caffeine can pass to an infant through breast milk, and the Audifort label tells pregnant or nursing mothers to consult a physician.
- Anyone under 18, a group the label also sends to a physician first.
- People who already sleep badly. Insomnia is on the FDA's list of signs of too much caffeine, and the blend's ginseng has its own sleep warning, covered on our side effects page.
- People on regular medication, since the FDA says some medications raise caffeine sensitivity.
If any of these describe you, read our checklist on who should skip Audifort before ordering.

How to tell if it's affecting you
The FDA's list of signs that you've had too much caffeine covers a faster heartbeat, palpitations, higher blood pressure, insomnia or disrupted sleep, anxiety, jitters, an upset stomach, nausea and headache. If you notice any of them, the agency's advice is to talk with your health care professional about your caffeine intake.
Because the amount per dropper is unknown, the simplest test is to start at one dropper, the amount the order page recommends, rather than the two the bottle allows (our page on how to take Audifort covers both sets of directions). Keep your coffee and tea steady for the first week or two so you can tell what changed. Another option: ask the distributor, whose contact details are printed on the label, how much caffeine is in a 1 ml serving. A straight number would settle it.
Apart from the maker's duty to meet safety and labeling rules, no law caps how much of a dietary ingredient a supplement serving can contain. According to the FDA's supplement Q&A, that decision belongs to the manufacturer and doesn't need FDA approval. The real caffeine figure is the manufacturer's to give.
