L-Theanine
Mentioned 4 times across 4 shows · first heard Jul 2025 on Good Hang with Amy Poehler.
The general take
Leanne Morgan uses L-theanine as part of a sleep supplement blend and is positive about it, though she seems slightly uncertain about the specifics of how it works. She recommends getting combination products that include L-theanine alongside other ingredients like GABA or chamomile rather than melatonin alone, and notes these are available over the counter.

…sleep supplement supporting improved sleep quality and consistency
“And the three main supplements in that category or that kit of sleep supplements are magnesium threonate, apigenin, and theanine, T-H-E-A-N-I-N-E. 100 to 400 milligrams of theanine taken again alone or in combination with the other supplements mentioned in this stack. Many people find that the theanine allows them to get really drowsy and fall asleep, sleep really deeply and they feel much more refreshed the next day.”

…L-theanine supplement for calming without sedation
“Now another amino acid that I love that helps calm the brain activity without sedation is L-theanine. Theanine is found in small to moderate amounts in things like matcha green tea. This is why when you drink things like green tea, you got a little bit of an energy lift, but it also has a level of calmness with it. That's because of the theanine that's found in things like matcha. But theanine is great around 200 milligrams before bed or just after dinner.”

…supplement stack for stress management and smooth focused energy
“Another great one, if you're somebody that's quite stressed and you want to learn to relax and focus more, L-theanine is a great one. So you can actually couple this with like your morning coffee, have a coffee, pop an L-theanine. You know, it's better than popping another type of pill, right? And you do that and you get this kind of like smooth focused energy.”

…leanne discussing sleep supplements with gaba and l-theanine
“So I do like to take a little melatonin, some kind of blend with a, you know, a GABA, a L-thenanine. Oh, wait, what is that? GABA what? GABA and L-thenanine. Okay. If you take one of those and you can get them over the counter, but just if you have a combination of things like chamomile or it's got, it's got to have more than melatonin in it.”
