Caffeine Content

Caffeine levels in tea range from zero to medium strength. What exactly does that mean? Typically an 8 oz cup of coffee can range between 100-200mg - this is considered high, especially when you compare it to energy drinks that only range between 70-80mg. According to the Mayo Clinic, caffeine consumption should be capped at about 500mg/day.

Black tea ranges between 15-61mg per 8 oz cup and green tea 24-40mg - still giving you the energy without the unwanted jitters and anxiety. So if you are looking for an afternoon boost or a tea to help you relax, narrow your search by caffeine and then pick out your favorite brew.
