L-Theanine 350mg, 150 (5 Month Supply) L-Theanine Capsules - Non GMO, Vegan and Allergen Free - Caffeine Free - Made in The UK by Nu U Nutrition

I normally get a different make of this product from Amazon and all my family take it with no noticable side effects. However It wasn't available so I bought this product with near identical ingredients. All three adults have tried alternative ingestion and time differences but all three adults are suffering from confusion, memory issues,blinding headache, brain fogging, sleepiness during the day(taken at night) and significantly reduced blood pressure. So we have given these to the Chemist to destroy for us and a few days after we are feeling better and more normal again. May just be us, but for same things to be happening with three separate adults seems more than a coincidence.

Again I find the supplements provided by Nu u to be excellent quality. Of course you cant always be sure how well they work but it is clear this L Theanine is another high quality product that may well help with a number of things.For me I find taking one every so often in the mornings helps to improve my caffeine intake (daily coffee) it improves mood like caffiene but seems to make it better somehow. I have heard L Theanine naturally would be found in green tea alongside caffiene so it makes sense it has a similiar effect to drinking green tea. Awake but not completely jittery from drinking foolish amounts of caffiene.

I decided to give L- Theanine ago after recommendation. I was looking for the calming effect of green tea without feeling jittery. Bonus, it's definitely helping with stress as well. I take it in the evening. I'm definitely sleeping better as well and my resting heart rate has dropped a bit as well since I began using this product. I will continue to using this one!

These made a positive difference within 48 hours. More of a gentle nudge to get up and about, rather than the jolting pseudo-amphetamine kick that can often happen with green tea if one isn't careful.

This is a super supplement. Great for calming anxiety and also a good partner to caffeine, to balance any negative physical effects it may have on you. I sometimes need a caffeine boost when studying, but it can give me palpitations and make me feel too hyped. Taking it (I don't like coffee, tea or cola) with L-Theanine totally sorts it out and I can get on with my work with a clear head and happy heart. This particular one is very good. Comes in the form of easy to swallow capsules, which is great. And it's pretty good value for money, too.

Have been taking L-theanine for a while and it helps me to stay balanced and reduce stress levels. This particular one is very well priced and from a company I trust. The supplement is giving me the same, expected results as other (more expensive) ones I've used in the past. So would highly recommend!

Too early to give it 5 stars are only taken it a few weeks. I’ve tried and tried to make myself drink green tea because of the health benefits but can’t make myself like it or drink it very often! Taking one of these L-Theanine capsules every day should give me all the benefits and none of the drawbacks of green tea. Time will tell but at least I’m not suffering the horrid taste of green tea. So far so good

I took one 350mg pill mid afternoon. I read that I could have up to 600mg a day and took another about 5.00pm. For me, I remember feeling heavy limbed and very relaxed, fell asleep within 30 mins of getting into bed instead the usual two hours, but I believe the supplement made me pee excessively through the night, which disrupted my sleep.I took one the next day and still weed a lot, but the following day wee became less but still more than usual. I hope the trend continues.
