Lipton Brisk Lemon Iced Tea has about 8 milligrams of caffeine per 12 fluid ounce can. This is a very small amount of caffeine.
Those worried about whether or not a can of Lipton Brisk Lemon Iced Tea will keep them up at night can rest easy. The 8 milligrams of caffeine per 12 fluid ounce can is less than 1/10 of the maximum safe level of caffeine intake, about 400 milligrams, as stated by Mayo Clinic.
This low level of caffeine per can means that people can drink several cans of tea without suffering from the more common effects of caffeine intake. These include, insomnia, nervousness, restlessness, irritability, stomach upset, fast heartbeat and muscle tremors.
Lipton uses a powdered mix to create their ready-to-drink teas, rather than brewing. This is likely the reason for the low caffeine content in their teas. The other varieties of canned and ready-to-drink teas produced by Lipton are similarly low in caffeine. For instance, their half and half Tea and Lemonade contains 5 milligrams of caffeine and their Peach Tea has about 9 milligrams of the stimulant. People should take care as this brand does contain a large number of sugars and artificial sugars, which may affect the health in other ways.
