L-Theanine 200mg Double Strength - Supports Health Sleep Response and Relaxation - 120 Capsules (Third Party Tested, Gluten Free, Vegan) by Double Wood

Excellent for mental alertness and energy that doesn't tap in to adrenaline like caffeine does. A steady, Zen energy that lets me accomplish everything I need to do in a day without panic attacks or burnout. Will be buying this product again for sure!

I have added this to a daily regimen for my older son who has autism. He struggles with different things. This has noticeably helped him be more calm and in the moment. I will continue to get this

I can't leap any tall buildings after taking it, but I guess it's doing what it's supposed to. Purchased to aid with falling asleep faster, and I can't say that it helped me at all. Not a ding on the company or the product, it just didn't work any wonders for me but you might have a different result. Worth a try if you're suffering from insomnia.

I take l-theanine daily to help reduce the anxiety and jitter from a medication I take. This supplement has definitely improved my sleep quality, without hurting my energy levels. The 200mg strength is nice, and they are easy to swallow and tasteless. The only negative is the price. It costs much more than some other brands I’ve used. Overall it is a solid choice though!

Good for taking before a nap. Helps me fall asleep, but not stay asleep too long.If you plan to take these with caffeine, I'd suggest first trying 100 mg and then only moving up to 200 mg if that doesn't remove enough of the "jitters". At the moderate levels of caffeine I normally consume, 200 mg of theanine is usually too much and makes me feel sleepy.You can also combine L-Theanine with N-Acetyl Cysteine for effective relief of some cold & flu symptoms.

This is a great calming supplement. I use it to manage anxiety or wind down at night, and it works without making me drowsy. I like that it’s paired with magnesium threonate and apigenin—it seems to support focus and relaxation nicely. Definitely helps take the mental edge off. The value overall, exceeds its price.

Very effective

I love this supplement. It really helps me to relax and I’m able to rest. Highly recommend
