PERFORMANCE IN A POUCH.

A small, soft pouch you place between your upper lip and gum. It contains 200mg of caffeine, L-theanine, and a supporting blend of MCT oil, B vitamins, folate, ashwagandha, ginger root and chromium. No nicotine, no tobacco, no sugar, and nothing to swallow.

The tissue lining your mouth sits directly over a dense network of blood vessels. Caffeine crosses that tissue and enters your bloodstream without passing through your stomach first. Published research comparing caffeinated gum to capsules found meaningfully faster absorption through the mouth. Most people feel a FEINE pouch in 5 to 15 minutes. A swallowed drink or capsule typically has to clear your stomach first, which usually means 30 to 60 minutes, and longer if you are working hard.

Because it is the dose the performance research actually uses. Meta-analyses on reaction time, muscular strength and endurance cluster around this range for an average adult. It is roughly two cups of coffee. FDA guidance is up to 400mg of caffeine daily for healthy adults, so one pouch sits comfortably inside that.

L-theanine is an amino acid found naturally in tea. On its own it is mild. Paired with caffeine it is one of the most consistently studied combinations in cognitive research: controlled trials report better accuracy on attention-switching tasks and greater resistance to distraction than caffeine alone. In practice, it is the difference between focused and wired.

FEINE pairs caffeine with L-theanine, a combination studied for attention and focus. There is also zero sugar, so there is no sugar spike to come down from. Caffeine sensitivity varies. If you are sensitive, do not stack FEINE with coffee, pre-workout, or energy drinks.

Onset can begin within 5 to 15 minutes. Caffeine remains in the body much longer and has an average half-life of roughly five hours in healthy adults. How long you feel the effect depends on body size, tolerance, food, sleep, and other caffeine consumed that day.

No. Zero nicotine, zero tobacco, zero tobacco-derived ingredients. FEINE is a caffeine and supplement product. It is not a nicotine alternative and it is not a smoking or vaping cessation aid, and we do not sell it as one.

Start with one and see how you respond. FDA guidance is up to 400mg of caffeine daily for healthy adults, which is two FEINE pouches. Count them the way you would count coffees, and remember any other caffeine you have had that day.

That is normal and it means the pouch is active. Saliva starts the release as soon as it is in place. The sensation usually settles within a few minutes.

Anyone under 18, anyone who is pregnant or nursing, and anyone sensitive to caffeine. If you take prescription medication or have a heart condition, high blood pressure, or an anxiety disorder, talk to your doctor before using any caffeine supplement.

No, and we will not claim otherwise. The research we cite is on the individual ingredients at comparable doses, published in peer-reviewed journals and linked in full below so you can read them yourself. We have not run a clinical trial on the finished FEINE formula. Every number on this page refers to ingredient-level research, not a study of our product.
