How much caffeine is in a caffeine pouch?

It depends on the brand. A 2026 review of caffeine pouches found them running from about 25mg to 200mg each, so 50mg is on the low side, and 200mg is the top of what EFSA treats as safe in one go for a healthy adult. Flint has 100mg in every pouch, printed on the tin. Whatever you buy, check the label for the per-pouch figure.
How does a caffeine pouch compare with coffee or an energy drink?

The big difference is how fixed the dose is. A UK Food Standards Agency survey found brewed coffee ranging from 15mg to 254mg a cup. In 2023, Which? found high-street cappuccinos ranging from 66mg to 325mg. Every Flint pouch is 100mg. Nothing to brew, nothing to drink, and coffee doesn't come with L-theanine.
Do you get a buzz from caffeine pouches?

There's no nicotine in Flint, so there's no nicotine buzz. What you get is 100mg caffeine, inside the range a mug of brewed coffee holds. How caffeine feels varies from person to person, so start with one pouch and see how you get on.
What are the pros and cons of caffeine pouches?

The pros: a fixed dose you can read on the tin, nothing to brew or drink, nothing to spill. The cons: some people get gum irritation, it's easy to stack caffeine on top of coffee without noticing, and there's no long-term research on the pouch format yet. Count your total and keep to 3 a day.
How many caffeine pouches can you have in a day?

The European Food Safety Authority says up to 400mg a day from all sources, and up to 200mg in one go, raises no safety concerns for healthy adults who aren't pregnant. Flint's guidance is up to 3 pouches a day (300mg), spaced out. Count your coffee and tea in that total. How to take it is on the Flint product page.
Who shouldn't use caffeine pouches?

Flint isn't for under-18s or anyone pregnant or breastfeeding. EFSA's limit for pregnancy and breastfeeding is 200mg a day from all sources. If you're sensitive to caffeine and one strong coffee is already too much, a 100mg pouch will be too.
Are caffeine pouches bad for your gums?

Some people feel a tingle or soreness where the pouch sits, and a 2026 review of caffeine pouches lists mouth irritation among the risks. There's no long-term research on caffeine pouches and gum health yet, so we won't tell you there's no risk. Switch sides each time, keep it to 20 minutes at most, and stop if your gums get sore. If you already have gum problems, ask your dentist first.
Do caffeine pouches have nicotine?

Some do, so check the label. Flint has none. What's in it instead is on the nicotine-free pouches page, and why the caffeine is matched 1:1 with L-theanine is on the nootropic pouches page.
Are caffeine pouches the same as energy pouches?

Usually. Most shops use both names for a nicotine-free pouch where caffeine is the main active. A few energy pouches also contain nicotine, and the name doesn't tell you the dose, so check the label for both. Flint has no nicotine and 100mg caffeine, matched 1:1 with 100mg L-theanine. In the EU, the energy claim belongs to the B-vitamins, not the caffeine: vitamin B6, vitamin B12 and pantothenic acid contribute to normal energy-yielding metabolism.
