Glycine Powder


  • Pure powder
  • Supports focus
  • Promotes mental wellness
  • Taste

  • Mixability

Glycine is an amino acid considered nonessential but nonetheless important in muscle maintenance and energy production. Glycine also functions as an antioxidant.


Serving Size & Timing

Glycine is recommended to be taken in serving sizes of 1000 mg to be consumed up to 3 times per day, depending on intended effect. As the body is able to manufacture Glycine on its own, a Glycine supplement is usually not necessary for most people. Always speak with a medical professional before use, especially if you have had a prior medical condition.

As long as suggested serving sizes are adhered to, Glycine should be relatively safe. However, there were a few reports of minor gastrointestinal issues when taking this product. Those that have suffered through a history of liver or kidney problems should avoid this product. Also, because fluctuating amounts of one amino acid will affect the levels of other amino acids in the body, other amino acids should be taken as well to level things out.


This product dissolves easily in water and juice, and it has a sweet taste to it. (Glycine may also be used as a type of sweetener in some foods because of its taste.) Once finished, this product should be stored in an area that is free from light, heat and moisture.

Glycine is often taken with Creatine because it boosts the effectiveness of the Creatine. This creates a reaction that builds muscle mass at an accelerated rate while continually supplying the body with new energy to store.

Customer Reviews

Excellent product
I use this 3-4 times per day. It's especially useful on my high protein diet, to balance out all the methionine I get from animal protein. Plus, it helps build collagen.*

On 5/2/2019 Elliott said...

Great relaxation/sleep aid
Good quality but I wish they actually had the larger quantities in stock.*

On 4/26/2019 Simon said...

The Missing Link
Fast dissolving, slightly sweet and pure white. Hydrolyzed Collagen gives me a slight allergic reaction. This product nicely fills that gap. Three grams with each meal and a gram to sweeten my coffee and I'm good to go.*

On 4/9/2019 Bill said...

Great for amino acid balancing*

On 4/6/2019 John said...

Excellent for detox and energy

Glycine Powder Works
I use it when I go to bed. It works most time, but not always as it not soporific
I wold advise it*

On 12/6/2018 KIRILL said...

Good product
Glycine helps control blood sugar levels if they are elevated and are also needed for a variety of health functions. Good product and sweet too. I use it sometimes as a sugar substitute. I've been sleeping better since I started using this too.*

On 10/10/2018 Craig said...

Works as advertised
This product has truly helped with my joint pain. I know that I could never actually eat or drink as it were bone broth soup so this is a lifesaver. My Dr. recommended this product as he uses it and I am so thankful!!*

On 8/9/2018 Robert said...

Glycine Powder
Glycine among many others benefits is stabilizing blood sugar lowering risk for type 2 diabetes and protecting collagen in joints reducing joint pain. That's I'm using it for. As a bonus I can limit sugar for my tea or coffee. *

On 8/3/2018 Wlodzimierz said...

What is glycine?

Out of the 22 amino acids vital for our body to function and manufacture proteins, glycine is the smallest and simplest, with only a single hydrogen forming its side chain. It is abbreviated at G or Gly and it is the second most widespread amino acid found in human enzymes and proteins.

The liver forms glycine from serine and threonine, which are also amino acids. As a solid, it is a sweet tasting crystalline substance and the principle amino acid within cane sugar. In the human body, the highest concentrations of this amino acid are present in the skin, connective tissues and muscle.
Thank you,

Glycine review
Really enjoyed this. Mixes easily in any liquid. It's a great balance to a high animal protein diet.*

On 6/4/2018 Elliott said...

Part of my night-time stack
As many have noted, it is a good addition to a good night sleep stack. I add it to glutamine, 5 htp, GABA and magnesium. Sweet dreams!!!*

On 5/25/2018 Natalia said...

Glycine Powder
I am on the ketogenic diet for Fibromyalgia and sleep deprivation. I have been using glycine in my smoothies for the health benefits and the sweet taste to offset some of the other powders I use. This is one of highest quality products I have come across. My naturopath suggested Bulk and each time I place an order I'm increasing quantities and variety. All their products are Top Quality.*

On 4/14/2018 Lorraine said...

Highly recommended
One ingredient: Glycine. I like that. No magnesium stearate or other additives. And, in my opinion, glycine is an essential supplement. 4g/day at bedtime.*

On 4/6/2018 Matthew said...

My staple supplement
Glycine powder has been the most enduring supplement in my regimen since my starting a "Ray Peat-inspired" diet in early 2015.

I believe I started supplementing with another brand's powder in late 2015. I remember indeed really being helped along in my mental health-crisis of that period and of early 2016.

I made the switch to Bulksupplement's offering later that year, and have enjoyed the taste and consistency, finding it higher in quality than my first glycine powder (of 2015).*

On 3/31/2018 Connor said...

I've been purchasing this product for months now and I absolutely LOVE IT (can't live without it). This method of purchasing through Bulksupplements has proven to really work for me and my overall health.*

On 3/27/2018 Tracy said...

Blends well
I have not been using it long enough to say for sure what effect it may have, but the powder has a nice mild flavor and blends very well in my water. *

On 3/20/2018 Stefanie said...

Really Helps With Sleep
I take 2285 mg (1/2 tsp) when going to sleep, along with Gamma Aminobutyric Acid (GABA) and Magnesium Glycinate. Adding the Glycine to my nightly cocktail seems to have helped me sleep through the night, I feel more rested and less fatigued the next day. I had been taking all the other stuff for a while, and was getting mixed results. After adding in the Glycine I feel I'm getting more restful sleep than ever before.

On 3/5/2018 Bradford said...

Glycine Powder
This powder is wonderful. I add it to my daily shake and i notice a vibrant effect on my skin. *

Glycine Powder
The following is a list of clinical trials, most double-blinded and placebo-controlled, recorded at the National Medical Library, MEDLINE, as abstracted by GreenMedInfo for Glycine:

1. High-dose glycine added to drug therapy in schizophrenics results insignificant improvements in cognitive and positive symptoms.
2. Glycine inhibits ligature-induced periodontal disease in rats.
3. Green tea and glycine modulate the activity of metalloproteinases and collagen in the tendinitis of the myotendinous junction of the Achilles tendon.
4. Supplementation with glycine minimizes rat aortic allograft rejection.
5. Glycine prevents hepatic fibrosis in rats with alcoholic liver injury.*

On 12/6/2017 Stephen said...

seems to help with sleep
I've been taking 3000mg before bed, along with magnesium, taurine, l-tryptophan, and 5htp, to help with sleeping through the night. Adding the glycine to my nightly cocktail seems to have helped me sleep through the night, and feel more alert and less fatigued the next day. I had been taking all the other stuff for a while, and was getting mixed results. I added in the glycine about a week ago, and reduced the l-tryptophan, and I feel I'm getting better, more restful sleep.
It dissolves in water readily and has an ok, very mild taste. *

On 10/9/2017 April said...

High quality product. Reasonable price and very fast shipping. Will definitely order from Bulk Supplements again *

On 7/14/2017 John said...

New to this product. I purchased from the great reviews here on the site. I cannot wait for the same results as some of the reviews.

Love Bulk Supplements, fast delivery, no mess, easy dissolving products and no fillers.*

On 7/11/2017 Tabitha said...

Good quality product with a pleasant sweet taste. It really helps with quality of sleep. Will definitely order again.*

On 7/10/2017 CRYSTAL said...

Fantastic in my coffee
I was already using this to add a little sweetness to my coffee in the morning (which is does beautifully without spiking blood sugar as much as sucrose) when I read about how good glycine is for healing dodging guts. So, you know, win win. I do notice that if I use too much in the am I get a little...too calm? Nappy? But you only need a little for noticeable sweetening.*

On 7/2/2017 Morgan said...

good quality, excellent Customer Service
Product was well packaged (improved bag seals), and in excellent condition-- not wet or caked, flows well.

Fast shipping, good follow up emails.
Website is easy to navigate

5 stars overall.*

On 6/20/2017 TY said...

Nice sleep aid
I use this in mint tea about an hour before bed and have noticed that it really helps me relax and sleep more deeply. Will continue ordering. *

On 6/11/2017 Clayton said...

Great Price
I did a thorough search as did my doctor and hands down Bulk Supplements has the best value! *

Glycine may improve HGH release during delta wave sleep
Glycine is a conditionally essential amino acid.

Glycine serves as both an inhibitory and excitatory neurotransmitter.

It is the chemically simplest and most omnipresent of all the amino acids.

It combines with many toxic substances, converting them to harmless forms which are then excreted.

This amino acid has a calming effect on the brain and is also involved in growth.

Research suggests that glycine may help promote deeper sleep.

Glycine also has a positive impact on attention and memory in adults.

Glycine may also help boost the immune defense system and has oxidative stress regulating effects.

Most people need to take between one to three grams of glycine to be effective.

I take at least six since I weigh over 200 lean pounds and studies show high doses are safe.*

On 5/20/2017 Danney said...

Great stuff
I use glycine to help with aches when I get up in the morning. After using another supplement with other things in it I started using this glycine from bulk supplements and have had great results. And as a bonus, it seems to help me sleep. *

On 4/24/2017 Bill said...

Sleep Aid
I have been using this as a sleep aid and overall recovery aid every night for almost 6 months. I don't know about the quality of this product, but glycine is beneficial for sleep and helping your body repair itself. It's definitely worth the purchase to have. *

On 4/17/2017 Ben said...

Good product
I have high xylene levels and my naturopath doctor recommended that I take at least 1000mg of glycine a day. I mix it with my morning coffee or smoothie. Adds sweetness to my drink. It seems to be helping as my xylene #'s have come down.*

On 4/10/2017 Valerie said...

Glycine Power
I read somewhere that Glycine helps with muscle loss in the elderly. Thought I'd give it a try. Bulk Supplements has the best prices.*

On 3/21/2017 John said...

I put into capsules and take daily for health benefits.*

On 2/16/2017 Patrick said...

Helpful for sleeping
I found info online re: using Glysine to help with insomnia and have found it to be helpful. Thanks. *

On 1/23/2017 Pat said...

Bought this product for improving collagen synthesis as well as for glutathione production. The body also uses glycine to conjugate toxins/chemicals as a major detoxification mechanism (especially benzene). Nice sweet taste. Seems like a quality product.*

On 1/5/2017 Curtis said...

works very well for sleep. will buy again.*

Glycine Benefits
I've been using Glycine along with a cheap gelatin the past month and a half and I had and unknown benefit happen. I've been suffering with Psoriasis on my right knee for the past year or so. Strangely since taking the products noted it has totally cleared up and is gone. I found this bulk Glycine and Bovine Collagen at Bulk Supplements and had to order since it was a great deal and great results. Thanks again BS.*

On 12/5/2016 Jeff said...

great product
this is the second time I have ordered this product. It tastes sweet and strengthens fingernails. I add it to my coffee, since coffee uses up glycine as you metabolize the coffee toxins. I also put it into other foods as a sweetener replacement. *

Glycine powder
This really helps with both sleep and aches and pains. Prior to use I would wake up very achy in my hands and feet but taking glycine has alleviated that almost completely. *

On 2/27/2016 Terrance said...

Helps put me to sleep
I used this product to help me sleep after a workout. I take caffeine for my evening workout and glycine helps me calm down at night. I'd recommend to anyone who just needs help going to bed when you're not tired.*

Glycine Powder (500g)
Fantastic quality, clump-free, tastes like sugar. Generally the dosages for this are rather high, so it makes sense to buy the powder in bulk.
Not only can glycine help calm the mind, but it also helps increase growth hormone. Our boy is small for his age and also exhibits ADD, so we are hoping this will help him on two fronts.*

On 11/12/2015 Thomas said...

I take 8-10 grams of Glycine a day so the large bags and reasonable price at Bulk supplements is a Must! I was previously purchasing from Carlson's at the health food store but it ran out way to quickly! learned about the anti inflammatory and back strength benefits from a doctor's lecture on Youtube. Glycine tastes mildly sweet, so can be a sugar substitute in coffee juice or tea. I love the resealable package, taste and quick shipping this company provides! *

On 8/31/2015 navia said...

Glycine Powder (1 kilo packs) and customer service
Product is great, has very good packaging, was easy to find on the site, and at a good price.

Also, on my second order I mixed up addresses, and the post office returned the parcel. I emailed customer service explaining the problem and I got an immediate response. They rerouted the package, at no extra charge. It arrived promptly.

I expect to make many more orders from here.*

On 8/7/2015 Kevin said...

No bad taste,mixes nicely. Another great product from bulk supplements. Love the simple website,lack of hyped descriptions and I find the reviews by other users more then helpful especially on how products taste.*

Good quality, pleasant sweet taste, quality of sleep was much better. Will be ordering again.*

On 6/4/2015 jaron said...

I buy it by the kilogram
Glycine is one of the few supplements that have helped me heal from some chronic muscle issues I've had, as it helps to lower inflammation in the body. I was taking up to 30 grams of it for a while, but it was really expensive to buy in stores where they only carry it in small quantities. I also don't like to buy capsules of anything as there's always a bunch of junk in there that I don't want to ingest. I'm now doing lower doses, but continue to buy from Bulk Supplements for the price, convenience and quality of their products.*

Unorthodox treatment for anxiety
I have been doing some extensive research into glycine for use with indivuals with anxiety disorders. Large dosing makes price a factor. After trying many inferior glycine supplements from many different companies (not all supplements are created equally, as well as many "bunk" claims of "purity" being utilized as a selling aspect), I came upon the glycine from this site. It has by far exceeded my expectations for quality, with price being one of the best I've found. I can tell anyone wholeheartedly, after many experimentations with plenty of "high quality" products out there, that the one on here is the best you can find. A quick side note, the order was processed extremely fast, and I received my order within a few days. I am completely pleased with all aspects of this site and will be a common customer from here on out.*

Glycine was the first product that I purchased from this site and Im very satistified with it. My work out are intense and I find that this product works great with creatine hcl, citruline and argine to promote blood flow. Thanks you Bulk sup for providing vitamins without all the filler and junk.*

Glycine Powder
Good product. Dissolves easily, has a sweet taste. I use it to help maintain blood sugar level and stomach bile.*

Glycine Powder (100G)
I mainly purchased this item because I had read in various sources that it could help with sleep. I've also read where Glycine can help with the body's production of growth hormone.
There is really no good way for me to tell if this actually does help with GH, but since I'm going to be using it for sleep support anyway the GH possibility is well worth it.
Anyway, I do believe it does help with sleep as long as I take it about an hour before going to bed. Seems like I sleep more deeply and sleep until my alarm goes off.
I will definitely plan on purchasing again.*
