Green tea is in BreathiZen for its antioxidants. Like any tea, it also comes with some natural caffeine. Here is how to think about it.
BreathiZen contains green tea extract, which naturally includes some caffeine; the amount is not printed on the label. If you are sensitive to caffeine, take BreathiZen earlier in the day and count it alongside coffee, tea and cola. The FDA cites about 400 mg a day as a general limit for most healthy adults.
Why green tea is in BreathiZen
Green tea is rich in polyphenols, plant antioxidants carried here for respiratory tissue that meets city air every day. It sits alongside organic lemon in the formula's antioxidant pair.
How much caffeine does BreathiZen add?
The label does not print an amount, so we cannot give you a number. What we can say: it is one ingredient among seven in a small daily spray, so it is not designed as an energy product.
