Tag: L theanine dosage

According to a 2017 review, Lipton's specially formulated Natural Energy tea contained 20 mg of L-theanine per serving. This is one of the few specific figures available, so how much L-theanine is in Lipton tea across its more popular product lines, such as its black and green teas?

Studies have shown that L-theanine can increase alpha brain wave activity, which is associated with a state of relaxed alertness. This unique amino acid, most famously found in green tea, can be an effective component for those seeking a smooth and sustained energy boost, particularly when combined with caffeine.

While L-theanine is widely regarded as safe in green tea, the question of whether *is L-theanine safe to take daily* as a concentrated supplement is more complex. Current research suggests moderate daily doses are well-tolerated for several weeks, but data on long-term safety, particularly beyond 8 weeks, remains limited.
