No narcotic haziness- just a bit calmer

Sarah December 8, 2025

I have ME/CFS and one of my symptoms is being hyper alert all the time and it's exhausting and stressful. Car rides are a misery and driving can be terrifying; crowds, noise, bright lights.... all tend to be interpreted as dangers so I'm constantly on the alert. I'm always on the lookout for new tweaks for treating my symptoms and making my life a bit easier. The l- theanine has calmed that 'fight/ flight' jumpiness noticeably in just a few weeks. I have been less tense in the car, less reactive to stimuli in general, have felt less tension in my muscles, and have been able to cut back a little on a medication that deals with stress- related IBS. I have noticed no side effects as yet; I am especially happy that drowsiness isn't even listed, so I can take this to make trips outside my home bearable even when I drive. I haven't really felt less brain fog or improved mental clarity, but that may come in time, and even if it doesn't, the reduction in the physical symptoms is more than reason enough to continue taking this.

This really helped lower my anxiety. I still have thoughts about having anxiety, but my body didn’t produce the physical symptoms.

Sleep

Smokey June 12, 2026

Idk about anxiety thing but if you want uninterrupted sleep this one for you, not good if there is emergency though lol because you'll probably never wake up if someone screaming,

This product really helped when I was mega stressed an overly anxious and there's no crazy addiction habits than can arm a person. But, ALWAYS check with a pharmacist or primary care provider to make sure it's okay for you %26 the meds you may already be taking.

Almost immediate difference in mood!

Poe August 9, 2022

After only 4 days of taking this every morning I've noticed a huge increase in my mood. I'm much perkier when I wake up and it's also easier for me to get up and going. I absolutely recommend this but obviously everyone is different and things won't always work for everyone but it's certainly worth a shot for the price!

5 stars.

Ben November 14, 2018

I've been taking this for a week and I wish I had discovered this 35+ years ago. What an amazing product. 1 cap. mellows me out for hours and it takes effect within 20 minutes of ingesting. It doesn't make you sleepy unless you take 2-3, but that's not necessary. If you want a mellow, clear, focused head take one 100mg. If you want to sleep, just close the bedroom door, close the curtains and get in bed. Before you can finish the sentence "I'm not tired, I can't sleep," you'll be asleep, on the same 100mg. It's better than melatonin. You'll wonder how you ever did without it. It may even help you forget or ignore your tinnitus.

Spring Valley L-Theanine: My Daily Ritual

Happy October 14, 2023

Step into the calming embrace of Spring Valley L-Theanine capsules, and let me share the serenity secret I've stumbled upon . This stuff is like a peaceful ritual for my mind – a whispered reminder to keep things zen. I pop one of these capsules, and suddenly the chaos of the day fades away. It's almost like a tranquil journey into the heart of a secret sanctuary. If you're seeking that elusive inner peace without any hidden agendas, give these capsules a try. Trust me, it's a divine experience in a bottle – all without any cryptic initiation rituals (wink, wink)!

So far so good

Bellajo April 24, 2026

Bought this to help calm my mind at bedtime. Only started taking a few nights ago. To my understanding have to take 7-10 days for it to start working. No stomach issue so gonna keep taking. Only reason gave it one less star was idk the results yet.

Ingredients Are Different Than Pictured!

ElizabethUnderhill July 24, 2025

What I received did not match the Theanine pictured. It is Spring Valley brand L-Theanine 100 mg 100 count, yes, but the ingredients are completely different! This item contains SODIUM LAURYL SULFATE. The stuff that makes shampoo (%26 some toothpaste) foam up. It also contains POLYETHYLENE GLYCOL. I'm not surprised people had stomach issues. Polyethylene Glycol is sold commercially as MiraLAX. This contains a laxative! I read the label on the website before I ordered this product. I stupidly took this before reading the label at home, not realizing it wouldn't match what I ordered. Huge mistake! It messed me up.

Definitely a waste of money. it's supposed to relax you and help you sleep but I kept waking up every few hours and had a hard time getting back to sleep and it made me feel weird and off. i would definitely not tell anyone to take these. I thought I was saving money bc I took melatonin gummies 3mg cvs brand fir years so I figured this was cheaper to buy the same dose of l thiamine that was in the gummies and the same dosage of melatonin that was in the gummies from Spring valley and it was the worst mistake . Don't do this it's scary as heck and I almost went to the ER. please don't think this or the Spring valley l thiamine is safe. it's dangerous
