THEANINE Products very well-sourced with unwanted fillers and synergistically compatible, Living in Australia a long way but packaging always survives the trip to get to me in one piece.

Lifeblud products are my fav! Thank you for offering such high quality supplements!
Really like the product, definitely noticed improved sleep, but didn’t realize it was in gelatin capsules. I don’t eat animal products On a daily basis so would prefer vegetarian option
I’m so glad that I have started taking the Thea supplement. Life is hard and it’s good to have help! I’m able to stay focused on tasks plus finding it easier to relax at end of day, and then get a good sleep. Plus I’m confident in the product - no weird stuff, no fillers or harmful chemicals. Just pure help for my body and mind.
I love the quality of your products!
Theanine I love this theanine! Been taking for couple of months and have suggested to others.
I really like taking this at night, it has helped me sleep and be able to relax.
Very calming My husband absolutely loves this. He says it makes him feel calmer and helps with caffeine jitteriness

Very calming This product is INCREDIBLY calming! I love taking this before bed; it helps me fall asleep and stay asleep. It is also great for enhancing productivity when working. I do computer programming, so consuming this helps with processing information more efficiently. This is also excellent for curbing crashes from caffeine!
Pleased with purchase Looking to bump up my amino acids along with proteins I am eating. Wish I had these when I was vegan.
Calm Added this (1cap, once daily) and have noticed I'm less likely to stress out over events and situations and more able to calmly think through to appropriate response. Sleep has improved. Thanks!
Stress relief magic Easily kicks in within less than 30 mins and I have a calm moody instantly and feel less stress at work especially
Improved sleep I really feel like this helps me relax and sleep through the night.
Outstanding I recently tried the Lifeblud L-Theanine supplement and was quite impressed with the results. I had been dealing with significant daytime anxiety and restless nights, often tossing and turning or waking up too early. After seeing a recommendation on social media, I decided to give Lifeblud a go, especially since they were offering a discount that was due to expire soon. Starting with just one capsule before bed, I was pleasantly surprised to find myself sleeping deeply without any interruptions. The calming effect was noticeable, and it has now become part of my morning routine as well, taken alongside my tea. I can confidently say that this supplement has made a positive difference in managing my anxiety and improving my sleep quality. I would definitely recommend Lifeblud's L-Theanine to anyone looking for a natural way to calm their mind and enhance their sleep.
Great product Enjoying the benefits!
Buffers stress like none else This product is incredible for lowering cortisol and helping the body become more resilient to the daily stress of modern life. I have been using this product for months now, and it definitely moves the needle with stress and overall feelings of peace and groundedness. I recommend this to every single one of my clients dealing with stress and they love it too!
Reduces stress I’ve been taking this off and on for many months now. Recently started taking it regularly, definitely helps to reduce stress and feel more calm.
