L-Theanine Supplement 8 oz - 90 Capsules: 90 Day Supply of Clean Bioavailable L Theanine for Relaxation, Balance, and Calm - Easy-to-Swallow Single Capsule Servings

Organika L-Theanine- Relaxation Promotion, Stress Support, Pure Natural Source, Calm Energy- 90vcaps I have taken this product long enough to know it helps with stress, anxiety and mood. I take one every evening and my sleep has also improved.

This has helped my mom's restless leg, and she's sleeping all night!!

I chose this supplement to aid in stress relief rather than sleep (it did not increase or decrease my daily sleep pattern, so I gave it 3 stars under sleep the category). I liked the effects of green tea in the morning but couldn't tolerate it in the afternoon because it disturbs my sleep. After some googling legitimate medical sources, I found that L-Theanine is a vaso-dilator that calms the nervous system. So I decided to try it out. But consult your doctor before taking any supplement. A typical cup of green tea contains about 25 mg of L-theanine whereas Organika L-Theanine dosage (1 capsule) is 225mg almost 10X that. It's like drinking 9-10 cups of green tea without effects of caffeine or the added polyphenols. Two points, in particular, found in the company's product description I found to be very important: FAST ACTING: Able to cross the brain-blood barrier for quick, effective mental support RIGOROUSLY TESTED: 30 years of tested, tried, and true quality; Organika uses 3rd party testing for unbiased results to reach and exceed the highest standards of Canada Health-including all major toxins and heavy metals. I will have to update this review because I have been taking 1 capsule for about 7 days now. One bottle should last for approximately 3 months thus it's pretty cost-effective.

I've been taking L-Theanine for many years. I've personally found it to be great as a subtle anxiolytic and as a non-drowsy sleeping aid (really!), and while I'm not qualified to make any authoritative statements regarding its safety, let's just say I won't be losing any sleep over what happens to be an extremely popular ingredient requiring no special labeling in countless Japanese snack foods and drinks. I usually purchase my L-Theanine in bulk powder form and fill capsules on my own. This is considerably cheaper in the long run, but the one-time equipment cost and the tedious capsule filling sessions aren't for everyone. I also order a pre-filled bottle on occasion to get a feel for what's out there - checking my work, if you will - and that's what I did this time. I hadn't heard of Organika before, but given that I'm in the USA, perhaps that's no surprise. They're a Canadian supplement brand and though they apparently have a significant brick-and-mortar retail presence, it seems to be pretty much limited to Canada at the time of review (August 2022). I'd like to think I'm in a better position than most to evaluate L-Theanine given my long history with the stuff, and 225mg is more or less my usual dose, so I've been carefully watching my reaction to this product over the week or so I've been taking it. I'm happy to report that I haven't noticed any difference between this and my own capsules. My experience therefore leaves me confident in the quality of the product and the brand. I'll point out two more things to wrap up my review. First, there are two broad categories of L-Theanine products on the market - those that contain "Suntheanine" and those that don't. "Suntheanine" is a branded active ingredient guaranteed to be almost completely pure L-Theanine produced via bacterial fermentation in bioreactors by Japan's Taiyo Kagaku, and is pricier but technically better than the L-Theanine extracted from tea leaves used in products like this one. However, if the extract is from a reputable supplier, purity will still be close to 100%, impurities will be inert and harmless (e.g. the occasional molecule of D-Theanine), and there won't be much of a difference in the final product - a mix of active ingredient(s) with fillers, excipients, etc. packed into a capsule or compressed into a tablet. In this case I don't see any reason to doubt Organika's claims that their L-Theanine is independently tested for purity and that the final product meets the relevant Canadian health standards. Second, this product uses vegetarian/vegan capsules probably made of hypromellose, a semi-synthetic water-soluble cellulose-derived polymer that does the same job as gelatin at a higher cost. Gelatin capsules are almost invariably produced from animal-derived gelatin, which some may prefer to avoid. Five stars.

Only tried one capsule and it made me very jittery and anxious. Unfortunately no returns so I’m out $12!

This L-theanine is just what I was looking for. I like that that is the only thing in it. I take this at night alongside some ashwagahnda and it has really helped my stress and cortisol levels.

Generally, I don't comment of efficacy of supplement because of the type of supplements that I take. For example, I can't really tell if vitamins are helping me or not. L-Theanine, an amino acid, is clinically proven to reduce anxiety, stress, and insomnia in some people. As a sleep aid, one capsule should be adequate. As an anxiolytic, two capsules might be a better dosage. I use L-Theanine and Apigenin (chamomile) when I need help getting to sleep. For me, it works better than melatonin (which I find to be ineffective). No medical advice is offered in this review. Please consult with your healthcare provider before adding any supplement to your diet.

When it comes to supplements, reviews are hard to give because they affect people in different ways. For me though, I found that when I'd take a L-Theanine capsule in the AM and drink with a cup of coffee, my focus did increase to help shake off the morning grogginess. For sleep, L-Theanine varies for me ... and this is not just for this particular product but in general. I've found that sometimes it would rev me up at night. But, I have had success getting a decent amount of sleep. Easy to swallow pills and you get a good amount for the price. I usually try to always keep L-Theanine on hand in the house so this is one I'd go back to.
