Give yourself the mental clarity you deserve.

What are L-Theanine Capsules by WeightWorld™?

L-Theanine Capsules were developed to assist in making our day-to-day lives easier and stress-free. We know that time isn’t something we always have an abundance of, so instead of having to wait for your tea to brew to help you relax and focus, we’ve created a convenient and easy-to-take capsule to help you save time and maximise productivity while keeping calm and collected.

All of us value a good night’s sleep, so tea in the evening isn’t always an option. For those who want the calming effects of tea in the evening, however, our capsules have been created to be completely caffeine-free. Each capsule is also enriched with lemon balm extract to promote relaxation and support your cognitive abilities.

Benefits of L-Theanine Capsules

Life can get hectic at times, which can lead to a plethora of challenges such as:

  • Mental fatigue
  • Nervousness
  • Cluttered thoughts
  • Poor sleep
  • Mood swings
  • Poor bodily resistance
  • Weight gain

A lot of the time, we accept that as part of being busy with our daily tasks, but that doesn’t have to be the case! Our L-Theanine tablets are ideal to boost your body and get your energy and mental balance back with just one capsule a day.

Who can take L-Theanine?

For anyone experiencing the negative effects of living a restless lifestyle, give your body and mind the rest and tranquillity it deserves. Whether you are:

  • Living life in the office
  • Looking after the kids at home
  • Working from home and struggling to wind down
  • Preparing for exams and need to focus
  • Just need that extra help in making your days that little bit easier

We have created this product so that it can benefit anyone who needs that daily boost.


Always scared of finding a surprise when looking at the ingredients list of a product? Fear not as our product consists of pure L-Theanine and is encased in Vege Capsule Shells which are made from Hypromellose which is tasteless while being completely vegetarian and vegan friendly.


This is an amino acid that is most frequently found in things such as green and black tea as well as certain types of mushrooms. L-Theanine is thought to promote a calmer mindset which provides all of the benefits of drinking a comforting cup of tea without all of the caffeine that keeps you up at night.

Lemon Balm Extract:

A member of the mint family, lemon balm is also known as a calming herb. It is known for its calming properties. Consumption of lemon balm helps in relaxing and unwinding after a hectic day.

Had a better sleep with these than my previous product. Well priced too!

I feel I get some indigestion from these because it's almost as if I have heartburn. But it's not too bad. I will continue taking these. The makers sent out the one with lemon balm to me after their earlier error and I am impressed.

I purchased these for my partner and have told him to give them a little while to work as he is taking prescribed medication. He had been prescribed 7 days of zopicone sleeping tablets, highly addictive medication which I didn’t want him to take and also didn’t help with his sleeping which would mean taking them for longer. I chose a more natural/herbal tablet to prevent any of the side effects that come with prescribed drugs. L-Theanine is all natural and has some great reviews. My partner said he went straight to sleep last night so I can only suggest they have helped.
