    • Excellent quality
This is a very pure product. I bought this to reduce my jitteriness when consuming coffee and it worked very well.

    • IMPORTANT!!! READ MY REVIEW!!!
I did alot of research before I purchased this product. It does exactly what I researched it for. It is a nutrient that comes from the tea plant mainly and from some mushrooms also. I used it to help me relax. It promotes muscle relaxation and calmness. You can add it to coffee and it drastically reduces the jitters. I also use it for sleep with L-Theronate and Apigenin. L-Theronate is the only magnesium developed by Harvard that crosses the blood brain barrier to the neuro transmitters to promote calmness in he brain. Apigenin is a nutrient extracted from thr Chamomile plant. I'm not a scientist so bear with me. Apigenin binds to the GABA receptors in the brain. In other words it promotes better sleep. It helps you fall asleep faster and stay asleep longer. I am not a doctor so please consult with your doctor. I did. I have been using this combination daily for over 8 months now and my sleep has improved significantly. Plus at a certain time at night, no TV, computer use or cell phone scrolling and a set regular time for sleep. Otherwise I recommend this product. I like to use products in the raw form. I put the tiny scoop into a table spoon of applesauce and down the hatch. The nutrients hrlp wit cognitive function. I definitely recommend this product. ... show more

    • Now in my nighttime routine.
Pure L-Theanine Powder’s good stuff. Comes in a nice pack with a handy long-neck scoop for easy dosing. The ziplock seal is solid, not like those flimsy ones that detach and ruin everything. Took it last night, and it really calmed those 3 AM cortisol spikes. Now in my nighttime routine.

    • Great for focus when combined with lion's mane
Great for focus when added to your coffee with Lion's mane. Simulates the effect of trendy mushroom coffees.

    • My person view of using L-Theanine powder.
I experience zero side effects when using L-Theanine powder, and add it to my coffee (mixed with caffeine, it improves my mental focus) every morning. I don't drink tea regularly and L-Theanine has green and black tea leaves, along with some mushrooms.

    • Works well for keeping you at an even keel
Good for anxiety to add a wee bit to your am drink without any side effects except calm and non drowsiness. Good to have for taking exams and going through traumatic experiences like a fire surrounding your property with lots of timber to burn. You still have a clear mind and can think quickly with out and anxiety. ... show more
