What is L-Theanine?
L-Theanine is a naturally occurring amino acid commonly found in green tea that is known for its calming effects.
It's popular in longevity supplements due to its potential to support relaxation, mental clarity, and stress management without causing drowsiness.
L-Theanine is valued for promoting a balanced mood and helping maintain focus, making it a useful addition for those looking to support overall mental wellness and healthy aging.
How does L-Theanine work?
L-Theanine works by increasing the levels of calming brain chemicals like serotonin and dopamine, which help promote relaxation and reduce stress.
It also helps to balance brain activity, enhancing focus and mental clarity without causing drowsiness.
By supporting a calm and clear state of mind, L-Theanine helps improve overall well-being and mental performance, making it a valuable supplement for maintaining a balanced and healthy lifestyle.
I tried theanine for the first time, it really works. I feel more refreshed, I can concentrate more easily at work :)

Formulated by cellular health scientists
Effectiveness of longevity supplements dramatically depends on correct usage method, dosage and synergy between each other.
Our products have been formulated in collaboration with nutritional experts of UCL (London) and biogenetics scientists of Vilnius University to ensure maximum anti-aging elements absorption into cells.
What is Longevity and Healthy Aging?
A 200-year-long lifespan – this is not just a slogan, but a realistic goal.
In 1961, American scientist Leonard Hayflick discovered that most human cells are capable of dividing up to 60 times during their lifetime before they die.
With each division, they mutate slightly and lose some of their original DNA epigenome information, making our bodies progressively older and more prone to disease.
Fortunately, scientific advances over the past 20 years have shown that there are ways to slow down – and even reverse – the degeneration process.
Frequently Asked Questions
What are side effects of L-Theanine?
L-Theanine is usually well-tolerated, but some individuals may experience mild side effects such as digestive upset or allergic reactions. Starting with a lower dose can help assess tolerance.
What to choose - powder or capsules?
Advantages of powder:
- Powder allows for precise dosage control, making adjustments easier.
- Powder is generally more cost-effective compared to capsules and can be mixed into various liquids for versatility.
Advantages of capsules:
- Convenience as they are easy to take and require no preparation.
- Capsules also mask the taste of powder, which can be beneficial for those sensitive to flavors.
- Capsules provide consistent intake with pre-measured doses.
Your decision should align with your preferences and lifestyle - opt for powder for cost-effectiveness and dosage control, or capsules for convenience and ease of use.
Can I take L-Theanine if I'm already on medication?
