Energy pouches
Energy pouches are oral pouches that contain caffeine instead of — or occasionally as well as — nicotine. Caffeine content is usually stated in milligrams per pouch and commonly ranges from around 20 mg to 150 mg or more. For reference, a typical cup of filter coffee contains roughly 80–100 mg.
The European Food Safety Authority considers single doses of up to 200 mg and daily intake of up to 400 mg of caffeine not to raise safety concerns for healthy adults, with lower limits for pregnant people. Count every source of caffeine you consume, including coffee and energy drinks.
Functional pouches
“Functional pouch” is a broad marketing term for nicotine-free pouches built around other ingredients — for example vitamins, amino acids such as L-theanine, or plant extracts. There is no single legal definition, and claims about effects are regulated in most markets. Treat bold claims with care and look for a full ingredient list.
Where they overlap
Some products combine caffeine with other ingredients and are sold as both energy and functional pouches. On PouchHunters, any product with a stated caffeine content is listed under energy pouches; nicotine-free products without caffeine are listed under functional pouches.
Comparing prices
The same rules apply as for nicotine pouches: compare identical products, convert to price per can and price per pouch, and add shipping. For energy pouches it can also be useful to compare price per 100 mg of caffeine if you are choosing between products with different strengths.
