Review: ⭐⭐⭐⭐⭐ Helped Take the Edge Off – Worth Trying - Why did you choose this product over others?: I’ve struggled with anxiety and panic now and then, so I’m always a bit nervous trying new supplements. I’ve seen people rave about L-Theanine, so I figured I’d give this a go — especially as it also has lemon balm. I took it in the evening with a cup of tea. About 30–40 minutes in, I felt a bit calmer — nothing dramatic or life-changing, just like I could settle a bit easier. I can’t say for sure if it was the supplement or just the act of chilling out with some tea and YouTube, but something definitely helped. No side effects for me, and it didn’t make me drowsy or weird — which was my biggest worry. It just seemed to soften the edges a bit. I’ll need to try it a few more times to see if it consistently helps, but first impression is positive. Not a miracle pill, but it didn’t make anything worse — and for that alone, I’d say it’s worth trying if you're feeling wired or on edge.
Review: 😌👍 - The capsules are nicely presented. It’s one a day and easy to swallow. I ordered these because I read about the great benefits of L-Theanine. After taking on day one I noticed I was more calm and focused wow 🤩 so I will definitely keep taking these capsules. Definitely value for money and I highly recommend 😁👍

## Features

- NATURALLY SOURCED L-THEANINE AMINO ACID: L-Theanine is a naturally occurring amino acid sourced from Camellia sinensis, the plant used to produce green, black, and white tea.

Traditionally rooted and simply formulated, this L Theanine Supplement fits seamlessly into modern daily routines.
- 180 CAPSULES – 6 MONTHS SUPPLY: Each bottle contains 180 capsules, providing a full 6 months of supply. Just 1 capsule a day is enough to enjoy the goodness of this amino acid. Developed for convenient, easy consumption, these L Theanine capsules offer a simple way to include amino acid in any lifestyle without any fuss or complicated dosing schedules.
- ADDED BLACK PEPPER & VITAMIN B6: Each L theanine capsule also contains black pepper extract and vitamin B6, offering a well-rounded combination. Black pepper is added for easier absorption. Vitamin B6 contributes to normal psychological function. Vitamin B6 contributes to the reduction of tiredness and fatigue. Vitamin B6 contributes to the regulation of hormonal activity.

### ⭐⭐⭐⭐ Research Lemon Balm - can affect Thyroid
*by C***H on 28 May 2024*

Bought in a rush, without doing my usual research. Have now read Lemon Balm can interfere with Thyroid function and you shouldn’t take it if you are on medication for thyroid issues. No disclaimer on the packaging advising this - so I’d suggest reading some studies. You shouldn’t also take Lemon Balm long term without breaks. Probably best to grow your own Lemon Balm (safer) and just use a purely L-Theanine supplement. I think it might be helping as I clench my teeth when I sleep but with this I seem to sleep deeply and are less aware of issues. Early days though.
