Good product.
I use this every night before bed. It’s very effective on me. Works gently and I sleep through the night. 👍🏻

Heard about this from a friend who knows I’m an anxious person who has trouble falling asleep. I take one capsule of this with one capsule of 5-HTP (helps with balancing serotonin) and one packet of Calm magnesium powder in 8 oz of water. This is my night night cocktail and I sleep hard. I’ve alwasy had trouble sleeping and this is the only thing that has worked for me. I wake up feeling more energized than I’ve ever felt in my life like, I actually have a desire to get out of bed and be alive. Overall, I’ve felt less anxious during the day. This stuff is great! I would like to mention that I also take pharma GABA in the morning which has similar benefits but doesnt induce sleep. It helps you focus calmly without taking something that makes you feel jittery like caffeine.

Good product
The product was recommended by a clinician (MD-PhD). He recommended this brand because of its batch to batch consistency. This means it is a quality product. This medicine works, but note that it takes approximately about 1 or more months to observe results, and varies for each individual. There are scientific studies about the active drug, not sure if about this particular brand***. Do your research. Do not take it if recommended unsafe by your primary care or mental health specialist. Highly recommended for those recommended to take it.

Helps me get a better night's sleep
I ordered the chewables in the past, and those worked great for anxiety. This time I ordered capsules, but after reading reviews saying the capsules don't work as well as the chewables, I just open a capsule and dump the powder in a glass of water. I take it before bed and I sleep more soundly.

outstanding results... no need to drink 4-5 cups of tea
takes the edge off my husband's anxiety disorder with no side effects. we read a bunch of studies on effects and selected this brand due to stability of concentration and production standards. it is one of my personal favorite new products of the decade... does what it says, makes my and hubby's life better and low daily cost (just 1-2/day works wonders). try this if you need calm or focus effects.

Works well compared to some other brands
There are several brands of L-Theanine around and I particularly like this one. I can't objectively say it is superior, but subjectively it seems to have more impact than some of the others. However, everyone's systems are different so there may be other brands that work best for you. Often it's a matter of finding the one that works the best for you.

Great Product!
Love this product! I use it for my son who, when tired, ramps up to out of control instead of slowing down. This doesn't put him to sleep, but rather just helps reign him in to focus. If we don't use it, he lays in bed tossing, turning and walking his feet up the walls and talking constantly. With this, when I tell him it's time to lay down and rest, he can do it and have a more normal conversation. Makes bedtime much more tolerable.

This product is excellent for PMS and PMDD
We cannot live without Suntheanine. It is a lifesaver for symptoms of Premenstrual Syndrome and Premenstrual Dysphoric Disorder.

I was so surprised how fast and how effective this was for anxiety at work I was losing my marbles on edge until I bought this

My go to. Prefer this for the morning as the chewables sweeter and these have just a little more. Take this vitamin (one this, one chewable) twice a day with magnesium. It's just enough to help with the peri anxiety (for me) and I have taken an extra tablet when needed.

I really really loved these and noticed a true difference compared to some of the cheaper brands like Organica.

I just received this order one day ago so have only taken one dose but I definitely feel calmer. Hopefully it will help me sleep better too.
