Just Vitamins - L-Theanine 200mg x120 Vegan Capsules (4 Month Supply) - High Strength Brain Power Nootropic, GABA Alternative, Non-GMO, Caffeine-Free - UK Made Supplements

Chances are that if you're looking at this product then you already know the beneficial properties of L-Theanine.I've used this brand a couple of times before with no issues, I normally take 1 capsule with a cup of black coffee when intermittent fasting in the morning. This really helps stave off the jitters that you often get with lots of caffeine, and instead you just feel relaxed but highly focused.Its great for productivity and well tolerated in the body with no side effects that I've come across.In reality any quality brand will be much the same, but this ones good on price, available on prime and does exactly what it's supposed to.Recommended buy.RPI

Not sure, I think taken regularly they have a benefit. Anyone advising taking this with caffeine as a cognitive enhancer, rubbish. There are probably 30 alternatives out there for that. This is more of a long term supplement, potentially helping to reduce stress and a good supplement to help adrenal glands that can become exhausted with prolonged stress.

Excellent product. As I write this, it is the cheapest on Amazon, (do the math yourself) but works perfectly. Calming, improves attention and concentration, reduces anxiety and promotes learning. Goes well with a cup of coffee. Great for anxious students or stressed computer types. Per a Japanese study, it also lowers blood pressure -- so if you have chronic low blood pressure be aware of that -- might not be for you. For the rest of us (most?) with high blood pressure, this is the ticket. Be calm, be smart, be aware. Part of what this world needs. Recommended.

Packaging is to a good quality and clearly labeled. Product in personal experience is good for its use, although 1 cap may be on the low end. I have purchased at £12.79 and £11.66, the product is now at £15.95.

I bought these because I read about L-Theanine in the nootropics thread on Reddit. Combining 200mg of L-Theanine with 100mg of caffeine is shown to help people concentrate. You can read up on it there and find studies done on this. It is also meant to relieve anxiety.Now it is difficult to say if it works because obviously the effect would be subtle but I have sometimes tried the combo when I am tired and irritable and have then felt calm. It could be a coincidence or a placebo effect but I have noticed it. Other times when I was already feeling calm or normal I haven't noticed a particular effect but again it's a subtle thing. So overall I am happy with it and would order again.Also it smells sweet and yummy. Even my cat came up to me and kept sniffing it out of curiosity. This makes it pleasant to take.

This is my second packet now and if you have a 'busy head', ADHD or are just overwhelmed, I highly recommend these! On really bad days have two before work and you will be able to think calmly and clearly! They also help you sleep deeply bizarrely as they have the same ingredient as green tea, but without the taste! Definitely worth buying to help support you in a busy life! :)

The reason tea does not make you jittery like coffee is this L-theanine a non essential amino acid.Works in a different way to most herbal remedies.This brand is very very competitively priced

I use these if I have had an exciting evening, too much caffeine or late caffeine. I have to say that I love them. They help with any anxiety (at least mild) and help you sleep. Even if I wake up I feel I can just nod off again which is not easy or normal for me, otherwise. I must add, just for full disclosure, I'm quite responsive to certain compounds so I can only speak for myself but hope other customers have the same, or better, experience.
