Horbäach L-Theanine Supplement | 400mg | 120 Powder Capsules | Non-GMO & Gluten Free

I read that this helps with sleep so decided to give it a try. I will say that after 20-30 minutes I did feel a nice calming effect. I didn’t think I would feel anything. It is somewhat subtle though. I have only taken it a couple times but I do think it is a good product. I use several other products of this brand & all have been excellent & prices are the best. I only took 1 capsule(even though 2 is a serving) if I could feel a subtle calming effect with 1 I’m sure 2 would be a more noticeable effect. Glad to have found this & at a reasonable price.

This product allowed me to lower my stress level.

I buy this brand of LTheanine when ever I run out. It works good, it’s cheap, and easy to take. I am definitely a repeat customer.

Makes me woozy, helps turn off thoughts before bed..

Very good, works great

Too soon to tell. First night l slept so good!

Great product, great value.

I’ve been using L-Theanine for about 3 years now, and I can confidently say it’s a game-changer for my focus and mental clarity. As someone who’s tried prescription stimulants like Adderall in the past, I was looking for something that could help me stay sharp without the side effects—and L-Theanine delivers. I take it in the morning with a cup of coffee, and the combo is perfect. It smooths out the caffeine buzz and gives me a calm, focused energy that lasts for hours. No racing heart, no crash, and no anxiety. Just clean, productive focus. I’ve noticed improvements in my ability to concentrate during long workdays and even while studying. It’s not as intense as Adderall, but it’s consistent and sustainable. Plus, I sleep better and feel more balanced overall. If you’re looking for a natural way to boost your brainpower, especially for work or studying, L-Theanine is absolutely worth trying. Just make sure to pair it with caffeine for the best effect!

As another review posted, these are 200mg capsules, not "400mg capsules". Very misleading.

Good

If you are thinking of using this for hair thinning don’t bother. It simply doesn’t work.

Great, helps quite a bit!!

I usually use California Gold Nutrition L-Theanine 200mg but decided to give this brand a try, as they're slightly cheaper. These pills are quite ineffective. I'd say they're probably only 1/3 the strength of a single California Gold Nutrition AlphaWave L-Theanine 200mg capsule. I won't be buying these again and can't recommend, until they check their formula and make sure it's all L-Theanine. I suspect it's about 50-66% DL-Theanine and only 33-50% L-Theanine hence the much lower effect.
