This Glycine Works Miracles ~ OCD, Anxiety, Depression, Dermatillomania, Insomnia GONE

RascalCateAugust 1, 2020✓ Verified purchase

NOW Supplements Glycine Pure Powder will give you safe, restful sleep. It also has a major calming effect. It, together with a powerful supplement stack I am taking, as changed the quality of my life. I am now experiencing longer, deeper sleep. Insomnia vastly improved. Anxiety is not just diminished, but gone. I no longer suffer from depression, OCD is vastly improved, focus is enhanced, brain fog cleared. I am experiencing weight loss, lost 2 1/2 inches off my waist, and credit all these effects to the glycine, in addition to the supplement stack I am now on. Pre-diabetes and insulin resistance is gone. BP normal. Healthy glucose/AC1/HDL/LDL levels on my blood test. No dietary/exercise changes, but I look and feel 20 years younger. I have energy! My doctor is amazed. 6 weeks is all it took for me. This Glycine powder is pure, has no undesirable taste, and is super easy to talk. I stir it in my coffee with hazelnut non fat, non dairy creamer, and I find it does not change the taste. I like the fact that it is pure glycine, not mixed with additives I find in capsule form. And as it is powder, you can easily take the exact amount you want, so you control your own dosage. I have had a prolonged, challenging rough patch in my life to deal with. Add to that, I'm a chronic insomniac and because of severe PTSD, I suffer from being in a constant state of hyper alertness, with tensed muscles and catch myself with clenched hands and tense shoulder/neck. Trying to lay down and sleep like that is impossible. Trying to just function normally throughout my day was impossible. Trying to function on two or three hours of sleep is impossible. In addition, all this causes high levels of cortisol and adrenaline; I watched my waist expanding. My cholesterol went sky high, my blood pressure soared, and I was diagnosed pre-diabetic. My GP bugged me for over a year to try an Rx, and when I finally caved out of desperation, the prescription medications made my symptoms worse as well as I experienced a few new ones, including frightening hand tremors. Tossed those medications in the trash the first week. I started doing research, tried a few natural supplement combinations that did not worked, and finally found the combination that does. Glycine is an important and integral part of the natural, clinically proven combo that has changed my life. I usually add this Glycine Powder to my midmorning coffee, then again add a bit to a beverage early evening. I immediately feel the calm and experience true relaxation. Read more

Great for Sleep, Relaxation, and Nighttime Calm — Clean Taste & Dissolves Well

TogueDecember 11, 2025✓ Verified purchase

This is one of the most effective supplements I’ve tried for nighttime relaxation and deeper sleep. The powder is extremely fine, dissolves easily in water, and has a naturally sweet, very mild flavor (glycine is slightly sweet on its own). It’s easy to take, even if you’re sensitive to textures or tastes. The biggest benefit for me has been the calming effect. I take a small amount before bed, and it helps quiet racing thoughts without making me groggy. It feels very gentle on the stomach and doesn’t cause irritation. On nights when I’m tense or overstimulated, this helps my body settle down. I also appreciate that it’s pure glycine with no additives or fillers — just a clean, simple amino acid. The value for the amount you get is excellent, and the packaging is solid. If you’re looking for a supplement to support sleep, stress reduction, or overall relaxation, this is a great option.

Wonderful health supplement

MartineOctober 18, 2025✓ Verified purchase

Good product. I use it as a sugar substitute in my coffee. I use 1/2 tsp but max dosage per day is 1 tsp. Glycine is very good for the liver, converts to Glutathione which is a powerful antioxidant. I also noticed my cholesterol dropped recently back to normal levels. Not sure if this helped or not, but this is a blessing. I could say more, but Amazon has strict limits on what I can say healthwise, so I will leave it at that. Glycine is an amino acid, natural product and very beneficial for my health. Look it up. You cannot bake with it, as it degrades with high heat, but warm coffee or tea is fine. Nice alternative for sugar, as is Monkfruit extract and Stevia. But... limited to 1 tsp per day only.

LOVE THIS PRODUCT

ez reviewsOctober 10, 2025✓ Verified purchase

Purchased this Glycine to take with my NAC, as they have synergistic benefits regarding glutathione in the body. The package arrived on time, and the bottle was bigger than I expected (always a win). The powder mixes eventually as you stir. I used warm water to speed things up. Overnight I felt an immediate change as my next day began with an easier morning, clear mind that lasted throughout the day, as well as elevated energy levels. I can't believe this one supplement made such a significant change, but now I am telling all my friends about it. No doubt about this product, the quality is superb, and for the cost, it is a no-brainer to try it out. Just make sure to follow the dosing instructions as I couldn't believe you only need such a tiny amount each day, but now I see. Read more

Good Stuff

Lolly999October 7, 2022✓ Verified purchase

I take this in the morning in my coffee so can't comment on its value as a sleep aid. I consistently used this product for approx 9 mos. When I stopped taking ir for a few weeks I gained a couple lbs. & knee pain came back. I also noticed that this product kept my anxiety down some. Since I hadn't been taking it, I was less motivated- no idea if that is just me or if this product really did help my energy/motivation. I can't say it made my face wrinkles go away but I feel like it helped my skin some over all- not huge results, just subtle. I am in my 50's with fair, (some) sun damaged skin so it can't reverse that. Honestly, I think I need to take more than the 3,000 mg for even more benefits but I will have to research that to make sure more is ok. Also, I found no clumps or bug bodies/parts in this brand. The reason I won't try another popular brand is that some reviewers found bugs and cardboard like clumps in the product. This product was quite pristine. Read more
