FAQs
How much L-theanine is in each tablet?
Each tablet contains 200 mg of L-theanine. The label suggests 1 tablet one to two times a day, so the most you would take is 400 mg a day. A bottle of 120 tablets lasts 60 to 120 days.
What does the research say about L-theanine?
Research is limited. In one small randomised controlled trial, 30 healthy adults took 200 mg a day for four weeks while researchers looked at stress-related symptoms, sleep quality and cognitive function. Small studies like this are a starting point, not proof of an effect for everyone.
When should I take it?
The label suggests 1 tablet once or twice a day as needed, preferably on an empty stomach, or as directed by your healthcare professional. Do not take more than the label suggests unless your healthcare professional advises it.
Does it contain caffeine?
No caffeine is listed. L-theanine occurs naturally in green tea, but these tablets contain only L-theanine and tablet-making ingredients such as dicalcium phosphate and microcrystalline cellulose, with no tea extract or caffeine on the label.
Is it gluten and dairy free?
The label states no gluten, wheat, lactose, soy, egg, yeast or fish, and no artificial colours, flavours or sweeteners. Best Naturals also lists it as non-GMO and sodium free, made in a GMP compliant facility.
