What owners say about L-theanine
4/5 Falling asleep fasterTaste & form“I've been taking l-theanine for like 8 years now, no side effects, withdrawls when I stop, or anything negative from it at all.”
4/5 Taste & form“I also recommend breaking 200mg pills into quarters, and try taking l-theanine with it.”
4/5 Deeper sleep“You're not gonna feel anything like L-theanine, glycinate is so subtle I forgot I took it until I realized I slept through the night without waking up at 3am.”
What owners say about GABA
1/5 CalmingFalling asleep faster“Just want to touch base on the GABA part.”
4/5 Taste & form“agreed, sleep + blood sugar + GABA support helped me more than pills”
4/5 Side effects“The problem with tonic inhibition of extrasynaptic GABA receptors, is that some inhibitory neurons inhibit other inhibitory neurons, and if excessive, can paradoxically cause synchronous firing in neural circuits (which is bad).”
