What is Magnesium Glycinate Powder? 

Magnesium is a vital mineral that is used in many biological processes. For example, it is a cofactor in more than 300 enzyme systems! It is also one of the most common minerals that people are deficient in so it is important to take a good Magnesium supplement. This is not the easiest thing to find though as Magnesium supplements are plagued by bad absorption and there are a few different reasons for this. The main cause is magnesium's physical properties. Most of the Magnesium that we ingest is absorbed in our small intestines through small spaces called tight junctions. Absorption through tight junctions is dependent largely on the size of the compound, its solubility, and its pH. These three issues all make it very hard for Magnesium to be absorbed.

Absorbing a Magnesium Supplement

Magnesium, when it comes into contact with water, attracts a large amount of water molecules which arrange around the Magnesium ion, this is referred to as a hydration shell. The hydration shell physically makes Magnesium bigger which makes it harder for it to pass through tight junctions in the small intestines. Compared to Calcium, Magnesium has a much larger hydration shell, which causes two issues, the first being that Magnesium has a much harder time being absorbed due to its large hydration shell and the second issue is that when Magnesium and Calcium are coingested, then they are going to compete for absorption, which is problematic because Calcium will generally have the upper hand due to its much smaller hydration shell, which will limit the amount of Magnesium that can be absorbed.

The second major issue that makes things even more complicated is that Magnesium increases pH levels at tight junctions when ingested in supplemental dosages. This is problematic because there are proteins in the tight junctions called Claudins that strip Magnesium of its hydration shell allowing it to pass through the tight junction. However, as pH increases, Claudins become less and less active. As a result, Magnesium limits its own absorption by gradually increasing intestinal pH.

Benefits of Magnesium Glycinate Powder

The benefits of taking a Magnesium Glycinate supplement is where Glycine comes in as an excellent pH buffer. By chelating Magnesium with Glycine, the rise in pH at tight junctions is largely negated, leading to significantly better Magnesium absorption. The Glycine in theory can also decrease the size of the Magnesium hydration shell and in addition to this, may allow Magnesium to be transported through amino acid transport systems. Magnesium is also fairly reactive and can react with Phytates that are present in our diet. Magnesium that has reacted with Phytates is practically impossible to absorb and this is highly problematic because Phytates are fairly prevalent in foods that contain large amounts of Magnesium, such as almonds and spinach. Chelating Magnesium with Glycinate, appears to reduce the reactivity of Magnesium with Phytates, thus enhancing its bioavailability even when it is taken alongside food.

Supplementing Magnesium Glycinate for Sleep Support

The final benefit of Magnesium Glycinate, is that it can increase the likelihood of L-Glycine making it to the brain. This is interesting, because L-Glycine may support sleep quality and so can Magnesium itself. Thus, Magnesium Glycinate is arguably the best form of Magnesium when it comes to supporting sleep quality.

Is This Magnesium Glycinate Supplement Fully Chelated?

Yes, this Magnesium Glycinate powder is fully chelated. It is not buffered with Magnesium oxide. 

Recommended Magnesium Glycinate Dosage

As a dietary supplement, take 1600mg of Magnesium Glycinate once daily.

    Best sleeping aid I've ever tried

    Highly recommend magnesium glycinate for helping sleep. I sleep faster and don't wake up during the night after using this product. Works better than melatonin. But it tastes awful, so I suggest to buy the capsules

    Best Magnesium Supplement

    This is overall the best magnesium supplement I’ve ever tried. I take this stuff every single day.

    Good Product But Not Worth The Hassle

    Good quality and works well but buying in powder form is not worth the hassle especially if you're going to be using it everyday,

  • Catalin Pirvu - 28th Feb 2021

    Please buy CAPSULES!!!

    I think it's pretty effective, but OH MY GOD THIS IS IMPOSIBILE TO INGEST. It will stick to glasses, it will stick to your tongue, it'll make your want to puke. Please buy capsules, do yourself a favor. Nonetheless, seems like a good product.

  • Jimmy Hudson - 30th Nov 2020

    Effective, calming, but OMG THE TASTE

    You thought bacopa was bad tasting, you thought ksm was bad... Just wait until you try this, it tastes like someone farted and mixed the fart gas with weird old hot rotten steak that's been left out in the sun. Besides that, it is actually pretty effective, which is why I give it 5 stars.

  • Arthur - 6th Nov 2020

    Terrible taste, but the best cost x benefit for Mg

    This product is incredible: a cheap way to get Mg and glycine is a magical substance. Overall, you sleep much better. However, I would get the capsules, as the taste is unbereable. Giving 5 stars because I encapsulate my nootropics, but I would give a 4 stars if I had to take it everyday with water.

  • Hugo Gonzalez - 28th Aug 2020

    Bad taste in exchange for great results

    This magneisum has been the best I have taken in regards to effectiveness. I have tried ither brands and left disappointed possibly because of the fillers preventing the magnesium to absorb effeciently. I have been able to get more sleep without waking up and I get deeper sleep. Also question for admin, should this taste bad? It tastes like plastic almost, its hard to explain the flavor its just a potent non-natural kind of taste. No bad smell it just tastes bad.

  • Sean Fitzgerald - 21st Jun 2020

    Best Mag I've had!

    I love this magnesium! I dont get stomache problems when taking this vs the oxide. I wanna try L-Threonate and Micromag too!

  • Mow Levise - 5th Jun 2020

    High quality magnesium

    Noticeable improvements in sleep quality. Helps calm down the mind and body before bed. Price for the powdered version affordable, too.

  • Yuri Garcia - 23rd Apr 2020

    Very useful staple of my suppl. profile

    "Off the shelf" MgGly brands I've used these years dissolve faster than NDs' product but at double the price. I find even prolonged stirring can leave some pasty flakes in my cup. Shaking the solution in a closed vessel takes care of that completely. Rinses easily.

  • Nathan Couch - 9th Mar 2020

    Perfect Relaxation

    I take 250mg 2x a day and 1g before bed. The smaller amounts during the day helps me calm down and makes my body feel relaxed, whereas the gram before bed truly helps me wind down and sleep all the way through the night. It’s definitely top dog in my nighttime stack and pairs well with Ashwagandha Sensoril and Cyracos Lemon Balm Extract!

  • Brain - 22nd Jan 2020


    I take 1 g before bedtime. It has a calming effect and improves sleep quality. Magnesium is an important mineral for heart health and the nervous system. I take it constantly.

    Mg Glycinate Powder

    I had a terrible time getting the order sorted out with several e-mails and eventual help from the chief accountant of the company. There was not enough of the product in stock to warrant free postage so I was given a discount code. Then the accountant offered a code for free postage and the discount was nullified. It took ages for the delivery with inordinate amount of time spent somewhere in Germany on the way. I had to go and pick it up from the post office in the centre of the city because it came by ordinary mail - not DHL at this end. The instructions on the powder give advice on quantities but there is no measuring spoon in the container so I had to weigh and now make do with a salt spoon from another product. It holds 700mg - so about half the daily dose. Should there not be a small plastic spoon in the large plastic container to help the user? As far as whether the powder works for me - I have yet to find out definitively. It doesn't taste good but I hope it's OK to mix in a cold drink. No instructions for this. ND Admin: Again, we are sorry for the confusion. The shipping issued happened because your post code in Taiwan matched a code in the United States. So our systems were thinking it needed to verify your address in the US, but you were in Taiwan. The strange error is already being looked at by our card processing bank. So hopefully that will not be an issue going forward. Regarding scoops, they are not accurate forms of measurement. We feel including scoops promotes the idea that you don't need a scale, which cannot be further from the truth. Accuracy matters. A 2 cent plastic scoop from China should not be what our customers use to accurately dose their powders. A milligram scale is needed for accuracy. We now offer our own scale for customers, or they can purchase another milligram scale elsewhere if they prefer, but a scale is absolutely necessary.

    Great Magnesium

    Among the top forms of magnesium. An essential to any supplementation stack, magnesium is needed every time the heart contracts. Deficiency is hugely widespread among people.

  • Sam - 6th Dec 2018

    Very well absorbed form of Magnesium

    Previous, I was using magnesium oxide. It took me 200% of the RDA/day for muscle cramps and twitches to stop. Switching to magnesium glycinate, I'm only taking 50% of the RDA (1500mg mag glycinate) and I have NO twitches or cramps. Based on that, I'm absorbing MUCH more of the magensium from this than I do from mag oxide. Based on my scale, a level 1/8 tsp is close enough (for me) to 500mg. I just toss a 1/8tsp in my mouth, swish it with some water, and swallow. I do this three times daily in between meals to spread it out over the period of the day. I don't find it to taste that bad. Another gulp or two of water and I'm good to go. I'm only taking 50% of the RDA doing this and it's much more effective than using mag oxide. Very inexpensive for chelated magnesium, and a 250gm tub of this will last me about 5 months. I plan on using this for my daily magnesium needs going forward. Good stuff. I will try Magtein at some point out of curiosity to see if it really does have stronger nootropic effects than the glycinate. Perhaps Magtein in the am, this in the pm. But for a 'general' magnesium supplement, I don't see a better option than the glycinate at this price.

  • The Phrenologist - 8th Nov 2018

    Great for hard-working muscles. Also sleep. Probably not your taste buds.

    I've been taking magnesium supplements for years and magnesium glycinate exclusively for over a year now. It's become one of the pillars of my supplement regimen. Out that of all the magnesium salts I've tried, glycinate remains my favorite for being the most gentle on my GI tract as well as the most effective for sleep. I decided to try the bulk powder form to use an addition to my hydration mix for work days. (The skilled trades are hard on one's muscles.) I was not aware of magnesium glycinate's alkaline taste, which resembles a milder but more metallic baking soda. At 300-400 mg (~40-50 mg magnesium, or 10-12% RDA) per liter, it still does the job of preventing muscle cramps. Much beyond that and the taste becomes...distracting. For the sake of the completeness of this review, I did use this bulk powder version for sleep a couple times at my usual evening dose (3000-4500 mg equating to 400-600 mg magnesium). And, as usual, it did a great job putting me in a restful state. At this dose however, there is no reasonable amount of water at which the resulting solution won't taste like industrial-strength floor degreaser. As I'd rather not develop a Pavlovian aversion to bedtime, I'll be sticking to capsules/tablets for sleep. For light supplementation where significant hydration is also needed, this powder remains a good choice.

    Glycine is a Potent Energizer

    I thought this would just be another form of magnesium but it turns out the glycine has a much stronger effect. This is a pretty crazy nootropic. Never thought it would be like this.
