    Description

    Benefits & Description

    Nature's Lab L-Theanine 200mg features this naturally occurring amino acid that promotes relaxation and calm along with enhanced focus.*

    Key Benefits:

    • Supports mental calmness*
    • Promotes relaxation*
    • Supports healthy brain function*
    • Promotes enhanced focus*


    Benefits of L-Theanine

    L-Theanine is a naturally occurring amino acid found in the tea plant Camellia sinensis. It helps promote relaxation and calm along with enhanced focus.* L-Theanine was discovered in tea leaves in 1949 by Japanese scientists. While that is where it is most commonly found, this compound is also present in some mushrooms. Supplementation allows for higher dosage and therefore a more noticeable effect than that from direct tea intake where it is combined with caffeine. Each Nature's Lab capsule contains 200 mg of pure L-Theanine for excellent support.

     

    L-Theanine for Relaxation and Calm*

    At high doses (higher than the usual amounts of L-Theanine found in a cup of black tea, 20 mg), L-Theanine has the ability to relax the mind without causing drowsiness. Exciting preliminary studies also suggest it helps increase alpha wave activity in the brain. This is important because alpha waves are the electrical signals produced by the brain during a relaxed state and boosting these may help when trying to go to sleep.

    Mental Alertness

    This incredible amino acid not only affects mental calm, but it also promotes healthy brain function and alertness. One study was done that measured alpha activity, the brain waves that play an important role in attention. Thirty-five participants were given either 50 mg of L-theanine or placebo. Electroencephalogram (EEG) tests were done at baseline and then at specified times afterwards (45, 60, 75, 90, and 105 minutes). Researchers found that there was a greater increase in alpha activity in those who took L-theanine compared to placebo, demonstrating that the amino acid had an effect on the participants' general state of mental alertness and arousal.*


    Suggested Use

    As a dietary supplement, take 1 capsule one time daily, preferably with a meal, or as directed by a qualified healthcare practitioner.

    Warnings: Pregnant or lactating women and people with known medical conditions and/or taking drugs should consult with a qualified healthcare practitioner prior to taking dietary supplements. Discontinue use and consult your doctor if any adverse reactions occur.

    We Build Around What Works

    "Most supplement brands begin with a budget and formulate around it. We take the opposite approach - starting with the research. We look at which forms offer the best bioavailability, which doses are supported by clinical studies, and what the evidence truly shows. Every ingredient in a Nature’s Lab formula earns its place. If clinical research doesn’t demonstrate real benefits at the dose we use, it doesn’t make it into the bottle."

    I have been taking this

    I have been taking this L-Theanine for the past week and love how it relaxes me and calms my mind. I suffer from anxiety and have noticed a huge difference in it since taking them and have noticed my quality of sleep is better!

    I love taking this product

    I love taking this product once I wake up and start my day. Working long hours this product helps me stay relaxed throughout my stressful day! This also helps later in the day when it’s time to unwind and get ready for bedtime.

    I’ve been taking Theanine for sleep. Quality of my sleep improved immensely, size of the pills is easily swallowable, package is simple. Due to improving my quality of sleep I finally have energy for work and hobbies, there is no dreariness in the morning. Much more clarity

    Restful Sleep in an Easy to Swallow Gel Capsule

    This is a wonderful supplement for anyone with anxiety, stress, or restless sleep. I take this in the evening and find that it helps me to wind down and relax. I sleep better when I take this as well. The capsules are easy to swallow and have no unpleasant taste or aftertaste.

    I can’t go without this

    I can’t go without this now. It’s so versatile. Can help you get better sleep but doesn’t make you drowsy, but it can help you be more focused at the same time. It’s amazing.

    Noticeable improvement in focus

    I work in a somewhat stressful job that can be a bit chaotic and full of interruptions. L-Theanine in particular helps me to focus on my work better and be more productive. I like that it's available by itself in this supplement. I've taken several noot supplements containing L-Theanine but of course they're full of other stuff as well. L-Theanine seems to be the one that works best for me and so I'm happy to have found it in this supplement without all the other stuff that I don't need.

    Part of our home stock

    From my wife Sarah: We keep a number of supplements on hand for whenever they're needed. This is one of those items. L-theanine can be combined with 5-htp and GABA for help with sleep, or by itself for a calming effect. I like this particular brand because of it's purity. It's free of sugar, salt, eggs, dairy, peanuts, tree nuts, fish, shellfish, yeast, wheat, soy, gluten, titanium dioxide, artificial colors and flavors. It's also non-GMO. The price on this is excellent and affordable.

    Didn't help me relax

    I used this product as recommended, 1 capsule a day which delivers 200g of L-theanine. I saw no benefits.

    I am generally an anxious person, and have been having some stress lately making me clench even more at night and causing even more jaw problems. I thought a supplement meant to aid in relaxing could help me decompress a bit and alleviate the physical problems my stress is causing.

    This supplement didn�t help me relax. In fact, it actually made me have bad dreams. After taking it for two weeks without improvement I finally decided to stop and the bad dreams went away.

    While this product might help some of you, I am very bothered by something displayed on the page that I noticed upon preparing for this review. They are advertising this as �FDA Registered� and that upsets me because the FDA does not issue registration certificates for anything. This is an attempt to make the na�ve customer think it is FDA approved, which it is not, without falsely claiming so.

    This kind of suggestive marketing makes me distrust companies even more, and it is one of the reasons I cant recommend this product.

    Effective

    I learned about L-Theanine from one of my daughters, and it has been a huge help with her anxiety and stress, she'll take one as needed, and doesn't have to worry she'll take too much, or any side effects.

    I decided I should give this a try myself, for when I feel anxiety, and it really does help take the sharp edge off and helps that anxiety fade away. So glad to have given this a try.

    The price when ordered ($9.00) was a competitive price, but has since gone up to over $16, so I will be shopping around for my next order.

    Made in the US l-Theanine

    I love that this product is manufactured in the US, despite it saying that some ingredients are imported. It's also non-GMO, gluten free, and free of most allergens.
    The pills were about 3/4th an inch and I had no issues swallowing them. About an hour later, I did notice a decrease in some of my racing anxious thoughts. I didn't notice a difference in my ability to concentrate but I overall felt in a better mood.
    This brand is a little more expensive than the average l-Theanine supplement on the market, but still overall a reasonable price for a 60 day supply if you follow the recommended dose of 1 capsule a day.
    I didnt notice a flavor to the tablet when taking it either.

    Really calms the body and makes sleep possible

    I recently discovered L-Theanine after taking L-Tyrosine for mental clarity and focus. I have a hard time falling asleep at the end of the day and I have issues taking Melatonin so I can't use it. This is exactly what I needed to calm my mind and body down and get fast asleep at night. L-Tyrosine gives me energy and L-Theanine provides complete calm and rest. This stuff works amazingly well and I'm usually asleep within 20 minutes after taking it. Great quality product, will purchase again

    I Found This to be Very Beneficial

    L-Theanine is believed to raise the levels of brain calming chemicals such as serotonin and dopamine to reduce stress, ease anxiety, and help you to sleep better. I have found this to be true. I started to take these because the little things were starting to bother me and I found myself being a little short tempered because work and life can be stressful. After taking these for a while I gradually noticed that the little things that I usually found "highly annoying" weren't. I stopped taking this supplement for a few weeks to see if it was really the supplement or if things were just less stressful and I noticed my stress tolerance becoming less and the little things are starting to get to me again. I will definitely continue to take these.

    I can not say for sure

    This supplement is supposed to help with anxiety. I have been taking it for a while and I can not really say whether it is doing anything or not. I can not tell you whether this brand is better than any other because I am not a lab. It is hard to review vitamins and supplements but I have to. What to do? Decent price. Give it a try if you think you need it. It can not hurt, as they say.

    Nice, good working, and low cost supplement.

    I got this Nature's Lab L-Theanine 200mg - Mental Calmness, Relaxation, Healthy Brain Function, Anti Anxiety, Restful Sleep - 60 Count, to add to my daily supplements. More precisely to my nighttime supllements , to help me sleep better I have used it in conjunction with my other sleep supplements, and I did notice a difference. I felt that feeling of sleepy type calm, much quicker, than if I had only taken my other supplement. So, I think I can say, in my opinion, that for me it is a help, and the cost is low for this 2 month supply.

    Calming

    A friend had recommended that I try L-theanine for stress and anxiety. I take these once a day and have noticed that I am calmer and can concentrate on tasks without my mind wondering. I am able to relax and fall to sleep easier at night. These small capsules are easy to swallow, no aftertaste or stomach upset. Each bottle contains 60 capsules - 2 month supply so this a good value.

    US Made and Tested

    After getting a counterfeit supplement online years ago I am very careful about what I order. Thankfully this Theanine supplement checks all the boxes. It is from a reputable company that is based in the US and has US manufacturing. The Amazon listing for the product is legitimate as it is created by the company that makes the products and they are also the seller of the product.

    The supplement itself works as expected. I've used theanine for stress relief for years and appreciate the calmness that it brings and also how it helps with sleep.

    Overall happy with the "Nature's Lab L-Theanine 200mg - Mental Calmness, Relaxation, Healthy Brain Function, Anti Anxiety, Restful Sleep - 60 Count".

    I take one before bed

    I have been using this before bed to help me relax and to calm my "chattering" mind. My mind likes to go a million miles an hour and if I wake up in the middle of the night, it is very hard to fall back asleep. I've used another brand for several months and have had good results with this amino acid. I am trying this one, to see if I get the same results for a lower price. L-Theanine is the same amino acid found in green tea. There are other uses for it, but I am trying it to lessen my anxiousness and help with my sleep. I read that this can be used with melatonin as well so that is helpful. I don't use it during the day, because it does make me feel sleepy. I have read that anywhere from 50 mg to 400 mg can be used so you may need to experiment to find your correct dose. I am pleased with this so far and plan to keep using.

    Initial impressions, L-theanine capsules for focus, stress relief, and brain support

    I have been taking the L-theanine capsules and established initial impressions. The capsules are small and easy to swallow. Each capsules is 200 mg and the serving size is one capsules per day. I have taken L-theanine in the past and believe it has been helpful with focus. I am not yet noticing notable benefits from taking the capsules. I usually take a capsule in the morning or in the afternoon. I have not experienced any side effects. There could be some impact on focus in a positive way. I will continue to finish the bottle and update. I am hoping that they are working in a way that I cannot feel. At the moment, I cannot confidently recommend them as a top choice based on my experience with L-theanine. However, I do think they are worth considering.

    Great for mood stability

    I was taking an expensive mood supplement that worked so well but cost me about 50 dollars per month. The main component of it was L-theanine though, and I quickly figured out that I could get high quality L-theanine supplements for much less. These ones are just as effective, they're easy to swallow, and they help a lot with overall mental well-being.

    Works well, noticeable within an hour.

    I like taking supplements that show an obvious effect within a short time of taking it. I'm going to have to give up coffee, however...again. Caffeine is definitely not a good thing for me, and I'm learning that. The L-theanine can help with side effects of coffee when used as a stimulant to get working, but L-theanine can't do everything to calm you down or help you to have quality sleep if you have your cell phone on and near you while sleeping, a reader device, or your wifi on. I turn off my wifi and put everything on airplane mode or leave my phone in another room, far from where I sleep. That all helps. Having a level mood, and attitude through the day and less of a nervous, hyped feeling is great, while you also have a clear head and motivation.

    This is a good product, authentic and effective. Most L-Theanine products are reasonably priced and this product is a good value priced at below ten dollars at the time of this review.

    Not competitively Priced!!!

    My TMJ dentist recommended L-theanine to relieve pain from clenching & bruxism, caused by stress and anxiety. I started on it over 6 months ago and it has definitely worked. It didn�t happen immediately, but it has worked, as I have stopped clenching.

    I take 400 mg at breakfast & at lunch, so this is only a 15 day supply for me. At $10 a month it�s way too expensive, so I will go back to my 400 mg 400 capsules from Horbaach, as it�s only $18 for almost a year.

    Helps with anxiety

    I find that L-Theanine really helps my anxiety. It doesn't help my sleep, but it does help my day to day mood. These supplements are easy to swallow, with no funny aftertaste. Each pill is a serving,so a bottle lasts 2 months.

    Works well

    I ordered this for my son who has been taking L-Theanine that his doctor has recommended for his anxiety. This one from Nature's Lab is a great alternative. It has the same 200mg strength and works just as well. It helps him calm down. The capsules are small and easy to swallow. No issues so far.

    This comes in a white opaque bottle with a plastic-wrapped lid. The quality seems good and the other ingredients in the list look simple and clean. Mine has an expiration date of 27 months from now. It is also much cheaper than the one recommended by his doctor. Overall, a good supplement for mental calmness.

    American made quality

    I've used L-Theanine for a while, and it works for me quite well. It may not work for all people, but I've found value in it for lifting my mood. Take a look at what dosing works best for you to find a level that works, as some people can get by with smaller doses, and more isn't always better. These end up being a great value over 100mg capsules, which strangely enough seem to cost just as much.
    These are US made and quality assured- for a great price!
