Research, dosage & full profilePositive experiences
“Theanine and coffe gave me a focus I cant describe. Like 'on it!'. On the line.”
“I felt noticeable effects from l-theanine + caffeine, ashwagandha, rhodiola and if everything fails bromantane has definitely noticeable effects.”
“If you haven't tried the combo yet, try it first. I dropped taking Piracetam after I started this combo, it works great!”
“I can see taking two at once for certain situations...L-Theanine/Caffeine, which can give you a calm sense of energy 3-4 times a day without tolerance being such a concern.”
“I accidentally took 800 mg once when I thought I grabbed my bottle of calcium and took a double dose (4 pills) but an hour later I was extremely calm, lethargic, had zero anxiety”
“L-theanine x caffeine (2x1) has greatly helped me with my adhd. Feels like the first adhd “meds” I’ve taken”
Negative and mixed experiences
“L-theanine and caffeine makes me want to sleep .. never feel energized after taking it..”
“emotional dulling I get from stronger focus promoters like 200mg modafinil or 2:1 L-theanine + caffeine”
“Nootropics/supplements I've tried in the past but haven't helped: L-Theanine + Caffeine”
“Long story short, I scored highest in the group, by a really significant margin, from being literally lowest.”
“Caffeine+theanine also doesn't help - it prevents me from falling asleep, but doesn't do anything to relieve the sleepiness and brain fog.”
“I like you tried, modafinil, l-theanine caffeine, tyrosine, tea, and much much more with little or no success.”
