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

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

I bought this as I have had a hard time finding a good anxiety medication. I've been through probably half a dozen anxiety/depression medicines and they either put me to sleep for three days (Remeron) or keep me awake (Wellbutrin). Others made me nauseous or messed up my GI system.I have a hard time sleeping as anxiety wakes me up in the middle of the night. Many sleep aides only help for about half the night.I was excited to learn about this product and that it is non prescription or habit forming. I bought a brand with a low dose as I had tried a 200mg version that was a gel cap that I couldn't break apart for a smaller dose. I've taken this at night and it helps me sleep through the night. I've switched to breaking it in half for 50mg and it is still effective. I'm very relaxed and find that I really want a nap after meals. But it does seem to help relax me, which is a great.That being said, I'm stopping it as I'm just too tired the following day after taking it the night before. I'm now trying Ashwagandha to see how that works.
