Review: Recommended by body builders. But I didn’t expect Glycine to help my sleep! No side effects - So I had Glycine on a list of supplements to try because I follow some healthy body builder types online. I am not one myself though. At all. I am not even a fit person nor a fitness fanatic at all. I’m older and not svelte currently. (I prefer natural remedies as first line defense when possible.) So I’m not a fitness icon here. But I do follow and read these healthy peoples posts, and they recommended Glycine. (Taurine too even. Plus many others). But I had Glycine on my radar the most. So Glycine has been on my list of supplements to try, but I just wasn’t in a rush since I’m not building muscles. Now I deal with insomnia lately. And I had read somewhere that Glycine could help. This was news to me since I had only associated Glycine with body building and muscles. So then I really wanted to give it a try for sleep issues. And so I ordered this bottle. I don’t have any loyalty to any Glycine brand yet. It was a pretty random brand choice. It’s my first time trying Glycine so it wasn’t easy to choose with the vast variety on desertcart. So my brand choice is totally random. Maybe the price and review numbers is why I landed on this brand. I can’t recall. Just had to choose and start somewhere. So I pulled the trigger and just placed an order to try Glycine. So now I take one Glycine in the later evening and then two more Glycine right near and closer to bedtime. And I always get drowsy with the Glycine. Every time. I can fall asleep now and I don’t tend to fight it. The Glycine seems to help with that too. It really does work for me and I’m a deeply ingrained night owl. I prob have a hyperactive brain. I know I used to be like this since I was a baby. A serious Night Owl. My mother said I was always playing in my crib at midnight a lot. Sigh. It’s inherent and nothing I can really do except manage it. If I take the Glycine too early though I I’ll sleep too soon and wake up at like 3-4 am. So I take it closer to 10 pm to get sleepy and to stay asleep longer. Glycine seems to really help me with my insomnia and I take it nightly now. Three is what is mentioned on bottle. And that’s my full dose so far. Since I’m a supplement user I’m already very aware to look for changes and side effects. So with any supplement I always monitor any minute or major changes and any extra side effects. I have none with Glycine. None. Just the good ones I wanted. My experience is just having that desired drowsy effect that I need. It works well for me and is mild in side effects but powerful in what I need it for. No cotton mouth no headaches no weird dreams no hangover head no lingering drowsiness. Just a good drowsy effect upon taking it and then a good sleep and a good wake up. It’s mild in use but powerful too. It has nothing bad about it. It works perfectly to address my insomnia with my overly active brain. I hope this helps everyone who might be looking for a good insomnia and sleep regulator. This does it for me. And I’ve tried many things.
Review: Amazing sleep aid - Wow! This stuff does the trick. Knocks me out cold and keeps me in a deep sleep- complete with bizarro dreams - until morning. Way better than magnesium glycinate. This stuff is gold!

### ⭐⭐⭐⭐⭐ Amazing sleep aid

### ⭐⭐⭐⭐⭐ Marked and measurable improvement in sleep type and quality!!!
*by ~***~ on November 17, 2025*

After far too many issues with achieving deep, restorative sleep that spans many years (verified by both my sleep app and my Apple Watch) which coincided with peri/menopause, I was on a mission to find a more natural alternative to RX sleep medications. I did a lot of reading, and decided to look into glycine a bit more. While reviewing options for it available here on Amazon, I came across Life Extension Glycine (1000 mg). I'm a highly skeptical person by nature, and I typically think that natural alternatives aren't usually more effective than our RX options, but let me tell you that I'm now a believer in the effectiveness of glycine, and here's why: I changed nothing in my routine when I started taking glycine. Beginning with my first dose, which I took around 9 PM that night, my sleep app told me that I'd achieved AN HOUR AND TWENTY + MINUTES OF DEEP SLEEP. For reference, my average hovers around only 30 +/- minutes per night. I'd woken up that next morning feeling surprisingly refreshed, so imagine how shocked I was at such a marked difference after only one dose! Of course, I sort of wrote that off as being an outlier, but after my second, third, and fourth nights with much the same experience, I couldn't (and can't) ignore that glycine appears to absolutely be having a positive, effective influence on the amount and type of sleep that I'm getting. It's been over a week of a marked improvement since adding this supplement to my night time routine. I'm feeling more energetic during the day, and am falling asleep far more easily at night. The capsules are colorless, tasteless, odorless, appear to dissolve easily and are absorbed quickly (I start to feel tired about 2-3 hours after taking a single capsule). I'm sleeping through the entire night, so the effects seem to last a solid 6+ hours, and it leaves me without feeling any kind of sluggishness or residual fatigue the next morning. I couldn't be happier with this purchase. This is the one supplement that I can say with absolute certainty has had exactly the effect all the hype claims, and thus far, the it's been better than my RX sleep medication as it comes without the morning grogginess or the concern of taking a RX med. This is worth a subscribe and save, and the cost is worth every single penny. This is rapidly becoming a staple in my night time routine, and deservedly so.
