Natural Factors Stress-Relax Chewable Suntheanine L-Theanine 100 mg, Non-Drowsy Stress Support for Mental Calmness and Relaxation, Tropical Fruit Flavor, 60 Tablets

I’ve tried several forms of L-theanine, and this chewable version with Suntheanine stands out. It kicks in quickly — usually within 20–30 minutes — and helps take the edge off without making me feel sleepy or foggy. I’ve used it during workdays, before social situations, and even in the evening when I want to relax without fully winding down. I wear a oura ring and my sleep is always fantastic after taking it. The flavor is light and not overly sweet, and I love that it’s chewable for fast absorption. This has become a staple in my supplement drawer — great for calm focus or a gentle mental reset without any crash. Have reordered it many times and have not had any issues in how the product was received or quality.

Love these! Personally I don’t have any side effects from these but everyone is different. I usually take these whenever my head hurts/ feels heavy or to help me sleep.

this product is extremely helpful when you wake up in the middle of the night and you have a hard time going back to sleep that's what L-theanine does. It helps with restful sleep!!

Bought for my adhd child, helps so much! Helps him focus with no side effects! Didn’t notice much help with sleep but the quality is worth the money! And the size didn’t bother him

Item was as described

Excellent product. I take this at night. Helps me sleep soundly, whether I take it with any other product or by itself. I've found no side effects at all. I use the chewable and it's a nice mint taste.

Best pill for relaxation

My son, who has never been diagnosed with an Autism Spectrum Disorder, still displays some Autistic tendencies. This is actually something that seems to run in my family with the men, just prior to puberty. Then when puberty hits, it seems to go away. When he gets overstimulated or has had a stressful day, he makes loud humming, explosive noises that serve the purpose of helping him to de-stress. That said, it's very annoying and also, he's already kind of the "weird kid" at school due to having some hearing loss that causes his voice to sound funny to the other kids. It is very hard for him to keep it together while at school, so he does not make those inappropriate noises and draw more attention to himself. The end result is that he comes home and makes them for hours to get them out of his system. He was also having trouble falling asleep every night due to being "scared" for reasons he could not explain. "Just scared." Nothing in particular he could point to. He was experiencing generalized anxiety. His dad suffers from this as well. The lack of sleep was very concerning to me. It was so bad that at 10 years old, we were occasionally have to resort to a Benadryl to help him get to sleep on school nights, after hours of relaxation techniques did nothing. I found this and, based on the reviews of others with children who have similar issues, decided to try it.We have been through three or four bottles now. Honestly, I only notice that it's working when my son starts relentlessly making those noises and I ask him when the last time he took his "relaxing vitamin" was. His answer is always, "Oh, I forgot. I haven't taken it since yesterday (or some similar timeline)". If he misses a dose or two, the noises come back. As long as he's taking it, every once in a while, I might hear him make a small sound briefly, but then he stops. If he stops taking it or misses doses, he again has difficulty falling asleep due to fears he cannot put a name to and he begins loudly and relentlessly making self-stimulating noises.He has to take the max (2 tablet) dose twice per day to get the effect. He weighs close to a hundred pounds, so that may be why. We started him out at one tablet before bed and that seemed to help the anxiety somewhat but it wasn't really cutting it. It wasn't until we upped him to 2 tablets twice a day (three times a day is the max) that we noticed the noises stop and the nightly trouble falling asleep ceased.He has not experienced any side effects of sleepiness during the day, or any other side effects that we can tell, which was my biggest fear in giving him a supplement that was unfamiliar to me. It's pricey, no doubt, but the benefits are worth it to me. I can avoid taking him to the doctor and running the risk of getting him a diagnosis that will follow him for life and possibly put on meds that could cause permanent side-effects like facial tics. He's a very smart kid who does well in school and this was a good alternative to medical intervention.My son doesn't seem to mind the taste, but I do wish it came in swallow tablets. The tablets are about the size of a quarter but also slightly thicker so they cannot be swallowed. I suppose you could break them into fourths and try to swallow them but I don't know.
