- BulkSupplements.com Magnesium Glycinate Powder - Magnesium Glycinate 300mg, Highly Absorbable - Gluten Free, 2.2g per Serving, 500g (1.1 lbs) (Pack of 1)

I’ve been using this product for a little while now, and it’s definitely effective. I noticed results fairly quickly when using it consistently. However, the taste is honestly quite unpleasant. It’s very strong and hard to ignore, so if you’re sensitive to taste, this may be a challenge. I found myself needing to take it quickly and follow it with something else just to get through it. That said, if you can tolerate the flavor, it does work, which is the most important part. Just be prepared the taste is not for the faint of heart.

I've used this product from this company for several years. It always had a bitter taste and when placed in water formed a crystal lump. I just put the powder in my mouth and drank water. Last year I received a bag that tasted very sweet, a lot like powdered sugar. It dissolved easily in water. I contacted the company because it was so different I didn't believe it was magnesium glycinate. I actually thought it was powdered sugar. They assured me that it had been tested and was magnesium glycinate. They said it was from a different source. I was very pleased and liked it a lot better than the previous version. My provider paused my magnesium for a few weeks to try to determine what was causing some GI issues I'd been having for a couple of years. When I resumed, I continued with the sweet version. All was wel. Once I finished that bag and started on a new one, the new one is bitter and forms hard crystal lumps when placed in water, much like the product I'd been taking for several years, or so I assumed. I contacted BS and told them it would be nice if we could get the same product each time. They didn't respond. Since changing bags, each time I restart the mag glycinate, I experience bloating, loose blood-tinged stools and cramping. I discontinue it for a week or so and try to restart. I've even tried restarting at smaller dosages. It doesn't matter. The result is still the same. I tried to contact BS through Amazon but Amazon blocked me with the message that since Amazon shipped the product, I had to contact Amazon customer service. I've voice my concern about this to Amazon because that fact that Amazon stores and ships the product does not make them qualified to respond to product questions. It's fallen on deaf ears. I called BS. The phone rep told me that BECAUSE IT'S A NUTRITIONAL PRODUCT I SHOULD EXPECT inconsistencies. I told her that was the most ludicrous thing I've heard in a while. BECAUSE IT'S A NUTRITIONAL PRODUCT is the exact reason we should expect consistency, especially if we're dealing with a health concern. Everyone's body responds to products in different ways. Once we find one that our body responds well to, we like to continue to use that product. She said that is not a reasonable expectation. She suggested that when I finish one bag, I could call and ask which supplier they were using at the time. When I asked what I'm supposed to do if they're not using the supplier that makes the product I want, she had no answer. After this horrendous experience on the phone, I contacted BS through their chat portal. Again, no response. If this is their official position, it brings into question the consistency of all of the other BS products I use. For several years, BS has been my go to for every product I need that they supply because I only get the listed product and don't have to ingest all of the additives and fillers that most other companies add and because until this last experience, I have, for the most part, been happy with the quality of their products and their pricing. Now I'm having to rethink my decisions.

This is the first magnesium supplement I've ever tried. I read in the book "Eat Fat, Get Thin" that magnesium glycinate is an excellent supplement for people who suffer anxiety with cramping. Why that's me! I used to suffer from cramps day and night. In fact, I was drinking alcohol every day because it was the only way I could loosen up the knots. My therapists would all recommend massage and masseuses would work on my knots with horror in their eyes. They would recommend hot stone massages because they couldn't loosen the knot with their hands. The one time we tried it whacking the knot with a hot stone was very helpful. Too bad the cramps came back three days later. For this I pay $200? I do eat lotsa bananas and salt. I do not live on supplements alone. In addition, magnesium will relieve anxiety that comes along with the cramping. Hmm... Note: the glycinate is also excellent because glutathione (the master enzyme that regenerates all your other antioxidant enzymes) requires glycine. How does it taste? Doesn't seem to ruin the taste of mocha smoothies at all. Also, tried it in warm water. Didn't taste too bad but didn't dissolve easily. I tend to take a highly variable amount when I'm starting something. I started off high - about 3-4 gms per day - split into 3 doses. After about 3 days, i noticed my cramping was starting much later in the day. At that point, I raised the amount because it was working and I wanted to check my response. I noticed the magnesium seemed to work quickly once my levels started to pick up. At first, the cramping would ease up, then a few hours later worsen. I used this to adjust my dosage and timing. Finally, on the fourth or fifth day, the cramping seemed to go away almost entirely and my mood shifted just as the cramps went away. I became almost giggly as I thought of a joke. The mood lasted for about 1/2 a day with me gigging at random intervals. The next day, my muscles relaxed fully and stayed that way all day long! My morning back stiffness from sleeping first eased up, then reduced to small patches of stiffness in my back. Why the odd mood shift? Well, I am bipolar and for my particular genetics, magnesium will make me manic - thus the giggles. Or maybe it was watching that fun pirate movie the night before. I did talk to my therapist and we agreed that was a perfectly normal reaction but monitoring the magnesium is a good precaution. Isn't this dangerous? Somewhat. The danger from mania comes from running 24/7 relentlessly with no time for rest. I've done this for months at a time without any assistance from magnesium. Cramping 24/7 isn't good either, I almost became alcoholic. It doesn't pay for me to stay on the low side either, the cramps come back quickly. Finally, magnesium is required for production of stress enzymes and with bipolar I need those enzymes in tip-top shape. But the magnesium did snap me out of a low energy funk at the cost of getting the giggles for 1/2 a day. Or maybe the pirates did it. For me, it's a question of walking the tightrope. Carefully. And for everybody else? Eat salty bananas and pace yourself with magnesium until the cramps go away. Waiting 3-4 hours between doses is just about right when zooming in on the correct level. Beats waiting two full weeks for cramp relief. Update: Mysteriously, my thyroid function has improved. My internist is giving me the look of one who has gone crazy because thyroids don't normally do that. I took a look at the long list of supplements that support the thyroid. The one that changed the most was the magnesium. For those of you interested in improving hypothyroidism the list of supplements is: natural iodine sources, selenium, zinc, B6, B12, iron, copper, magnesium, carnitine, CoQ10, B2, B3, A, C, E, thiamine, high quality protein, potassium, chromium, manganese, omega 3, choline, barley grass or spirulina, B6, B12, folate. Almost every item on the list comes from a multivitamin except magnesium (about 3-5 gms per day when I'm cramping), CoQ10 (200 mg), C (6 gms per day), protein, chromium (1000 mg), omega 3 (12 capsules of the bulksupplements fish oil per day), choline from alpha GPC 50%, and spirulina. Update 7/23/2017 Thyroid condition - still in progress but my endocrinologist has cut my thyroid medication. We'll get results in fix weeks time and see how much my thyroid can produce. I spoke with my doctor about the results from the magnesium. As far as I can pin it down, excess magnesium does give me the giggles reliably. In addition to the thyroid improvement (? hard to pin down - too many other supplements), my emotions became much more complex. Seven months ago I was supplementing only with Hardy's Essential Nutrients (a multivitamin formulated for people with brain conditions) and inositol and I was calm. I was calm even in the face of the most outrageous provocation. It was a marvel to everyone that I didn't react negatively and after a lifetime of overly passionate responses a huge relief to me. Now with the magnesium, I feel a range of emotions again including mixed emotions. It's a burden and a relief. I'm irritable again but I've regained my sense of humor. My doctor's level of concern over my nutritional depletion is higher than ever. But we both agree the risk was well worth it. I was almost inhuman before. I'm also on lithium and side effects include random muscular twitching and restless legs syndrome all over my body. So I would drop things all the time, lose my balance or suddenly accelerate the car. The twitching and restless legs is greatly reduced or gone away. This is consistent with medical recommendations to supplement with magnesium to treat tics. I could practically see the gears spinning in my doctor's head when I reported this. Doctors routinely recommend using Ativan (an addictive anxiety medication) to control the restless legs. Magnesium is a laxative. The more bioavailable the gentler. It is hard to OD on magnesium because you'll, errrr..., just lose it. It happened when I went over 5 gm. (The amount you can tolerate will depend on your gut health.) And as the magnesium cleared the system, my giggles went away in minutes. Once again, it's got to be the gut that is busy using the magnesium to produce the giggles. Now, with bipolar sometimes you get mixed states. These are difficult to treat and last much longer than mania or depression. They also inflict the greatest damage both biologically and socially. I plan to ambush my next mixed state with the magnesium to see if I can break it. My doctor's eyes gleamed when I mentioned this. How we both love a good experiment. So far I've used up about 90 gms of my 100 gm supply getting to this point. Clearly, I was severely depleted (daily muscle cramps that resist massage and other treatment). When I went into this, I was terrified that I would self-induce mania, no idea what I would gain; I had no idea what the therapeutic dose is for bipolar. I wondered if the risk was worth the gain? YES, WELL WORTH THE RISK. When you are depleted, the therapeutic dose is for the birds. Just use your symptoms as a guide. And using my cramping as a guide, no matter how much I OD, two or three days later the cramping starts again. I've never heard of a less scary mania. Finally, my deathbed wish: I want to be hooked up to a magnesium IV. I plan to die laughing. Update: August 13th, 2017 It's been at least 3 weeks since I took my last dose of magnesium. The cramping has gone away and stayed away. I seem to experience some rare twitching but it's so mild I'm not really sure. I tucked the magnesium into the freezer, just in case. But so far, my daily multivitamin seems to be able to keep up. I should also report that I experienced brief periods of rapid heartbeat and heart palpitations usually after I ate food while on the magnesium. About two weeks after I stopped the magnesium this went away. This is a known side effect of magnesium. You can either stop or lower the dose. I decided to just keep going until the magnesium deficit went away, then stop. Update Sept 26th, 2017 Yes, it is true. My thyroid is producing more thyroid hormone. I've got the blood tests back and the doctors reduced my Synthroid from 75 mcg to 50 mcg. It looks like the magnesium is the last in a long line of helpful supplements. But the good news is - you can supplement your thyroid and improve function. Of course, the trick is... which supplement is the one you need most? Update Nov. 5, 2017 I've been manic for almost two months now and it's definitely been the longest period of cheerful mania I've ever experienced. Every time I slip into that nasty brooding irritation where I can't let go of my problems, I take some magnesium glycinate. It's not even that much about 400 mg for 3-5 days is enough to restore the balance. Normally, I skip the magnesium because my multivite is enough but not when I'm stressed. Tip: If you are experiencing cramping, you may want to consider BulkSupplements Pure Taurine Powder (250 grams) in addition to adding electrolytes. Taurine is a sleep aid, balances your electrolytes, prevents cramping, helps lower blood glucose. It also inhibits excitatory neural pathways in your brain which is why it's a sleep aid AND it will help prevent mania (if you're bipolar). However, if you're depressed, it will depress you even more - DO NOT TAKE TAURINE if you are depressed. Taurine works quickly (wears off in one day), Take it in the evening after dinner or before bed.. Update Nov. 27, 2017 I had not mentioned it because the status was so uncertain but the magnesium deficit helped my doctor diagnose a gut infection. Gut infections are invasive microbes that enter your gut and then somehow manage to destroy the balance of your gut microbiome. Most of the time they are already in your gut but your healthy probiotics keep them in check. Things that can definitely upset the microbiome include antibiotics, proton pump inhibitors (PPI's), illness, massive allergies that inflame the gut leading to leaky gut, environmental poisons (mercury) and alot more. Bad gut infections (and mine was not good) will strip you of essential nutrients - vitamins, minerals. Finding two or more nutritional deficiencies is the most reliable way to detect a gut infection. However, conventional doctors don't receive training in diagnosing nutrient deficiencies. How did my doctor diagnose the gut infection? She read about it - realized I had multiple serious nutritional deficiencies because I kept finding and fixing them AND I was taking Hardy's Essential Nutrients - one of THE most bioavailable multivitamins you can buy. And I was still deficient. She sent me to talk to Hardy's because they specialize in overcoming obstacles to absorbing nutrients. The Hardy's product specialist did a great job diagnosing me (it was not easy) and put me on an antibiotic to kill the gut infection. I'm still tapering off the antibiotic but I'm still hunting down vitamin deficiencies but this time - I find symptoms that I used to have. Gone now. The most visible change? My skin tone has changed from an ashy-yellow to more of a peachy-yellow. People I haven't seen in a while just bust out "You look healthy!" Is it over? Alas, no. Once your gut probiotics go down, every opportunistic microbe thinks they can take over. It's safer to take probiotics forever than to assume what's left of my gut biome can fight them off. Am I still taking magnesium? Occasionally and only when needed. Since I'm bipolar, the manic episodes generate quite a bit of stress. I find taking about 250 mg about an hour before bed is extremely restful and I seem to sleep more peacefully. This works out to a week every 2-3 months. This is on top of the magnesium in the Hardy's Essential Nutrients which has the "optimal" amount. But I'm hoping it will continue to drop as the gut recovers.

Buying the Magnesium Glycinate as a powder is much cheaper than buying it in tablet or capsule form so I thought I'd try it. I had hoped using it would allow me to stop my RX for heart palpitations and tachycardia. My cardiologist said for MY condition it was safe for me to try. Check with your doctor before making any changes to your medication. It did stop the heart palpitations and over the last month the tachycardia has improved but probably not enough that I won't need to go back on my RX again. I'm still giving it a try for a little longer. I will continue taking the supplement however because it definitely had a positive effect regarding stopping the palpitations which in my mind means I must have been Mg deficient. I have not noticed any other differences while on the supplement. The taste was terrible when I was just mixing it in water. I read suggestions to mix it in orange juice and that has made a big difference. I am able to mix it in a small amount of OJ which I can get down in 1 big swallow and it's easily tolerable that way. Seems to be a good product. I rated it 4 stars not 5 due to inconvenience of using a powder and taste. UPDATE 9/15/18 - I like the product well enough that I just bought it again in the 1kg size and bumped up my review to 5*. I'm fine with the taste now and while the product is still more inconvenient than a tablet, the cost makes up for it.

3.5 stars because of a dosage issue. This is labeled as magnesium glycinate, but is actually a cut of mag glycinate and magnesium oxide. This would be totally fine EXCEPT, they don't label the percentage of each used. That's a problem. Because in your gut magnesium glycinate is absorbed at about 80% but magnesium oxide is only absorbed at about 5%. So for science lets say they cut it 50/50 and say one serving is 300 mg of elemental magnesium. Based on the absorption rate you are only getting 127.5 mg of magnesium per serving(only about 42% of the advertised serving listed). Also that's being generous because based on the price for this they may cut it even more harshly.(just my guess based on how cheap it is compared to other glycinate options) The major problem is WE DON'T KNOW, BECAUSE THEY DON'T DISCLOSE IT. However, it's still a good bang for your buck just be aware that you will just have to use a higher dose than you think and will have to deal with some clumping on the bottom of the drink you mix it with because magnesium oxide clumps and tastes bitter.

The title of my review should not be construed as a problem with the supplier Bulk Supplements. I consider this product to be a commodity with inherently unavoidable characteristics. See also my in-depth answer to the posted question: "Does this dissolve in water?" The water supplied by our local utility is quite soft. When I vigorously agitate the labeled serving 1/4 tsp of this powder in 12 fl oz of Brita filtered tap water (boiling) I observe that almost all of the powder remains undissolved. After the powder particles settle, a flocculent remains suspended. Next, I try a sip of this mixture and there is a sharp, pungent taste of ammonia. Having some chemistry knowledge, I knew that flocs form as a result of pH conditions. I also knew that aqueous ammonia is alkaline. So I tested a hypothesis that an acid solution might completely dissolve a given quantity of this powder, and also simultaneously release its ammonia into the atmosphere. It turned out that 2 Tbs of boiling white vinegar (labeled as 5% acidity) was just enough to completely dissolve 3/8 tsp of this powder while preventing flocculation and avoiding dissolution of ammonia. This enables 245 mg of elemental magnesium to be absorbed via an empty stomach. But I will instead choose to consume magnesium citrate powder, even though it too is practically insoluble in water. I experimentally discovered that 11/16 tsp can be completely dissolved in just 1 Tbs boiling vinegar. Thus it has approx 5.5 times the solubility of magnesium glycinate (in vinegar). Moreover, it contains 16% elemental magnesium, whereas magnesium glycinate contains only 14% elemental magnesium. So 11/16 tsp of the citrate powder has 383 mg of magnesium. Considering that the gycinate powder is denser than the citrate powder, in order for the glycinate powder to match that I would need just 0.59 tsp of it. But... The magnesium glycinate must first be dissolved in 4.7 Tbs boiling vinegar. No, thank-you. Perhaps this product should be regarded first and foremost as a source of glycine rather than primarily as a source of magnesium. However, beef gelatin is also a source of glycine, and its ammonia (if present; probably not) is low enough so as to be tasteless. Moreover, it's easily dissolved in boiling water, obviating the need for vinegar, which is corrosive to tooth enamel. But its dry granules have a glycine content of only 27%, compared to this product's glycinATE content of 86%. Suppose I consume 1 Tbs of beef gelatin granules (after dissolving them in boiling water). I would be getting 2.6 g glycine. In order to match that in glycinATE, I need only consume 0.64 tsp of this product, but the caviat is that it must first be dissolved in a little over 5 Tbs boiling vinegar. Again, no, thank-you. In summary, the alternatives to this product are not only inexpensive, they are also more effective (superior solubility) and are FAR SAFER (This item is contaminated with ammonia and at least one insoluble powder). So if magnesium is the reason for your consideration of this product, then magnesium citrate is the better choice. Or if glycinate is what you're after, then choose gelatin granules instead of this item.

Good quality magnesium that helps me sleep better, don’t take too much though as it will make you have diarrhea.

I asked Bulk Supplements how much Magnesium Oxide is in this powder. They explained that the original Magnesium that the maker uses to make this powder is Magnesium Oxide. It undergoes a chemical process and turns into Magnesium Glycinate. A web search shows that this is how Magnesium Glycinate is actually made. Magnesium and glycine does not occur naturally. Magnesium oxide does occur naturally as a mineral called periclase. It can also be produced from the calcination of magnesium carbonate or magnesium hydroxide. I have pasted what Bulk Supplements says at the bottom of my review. I also pasted the AI overview from my web search, so you can understand how Magnesium Glycinate is created. It is true that this powder does taste horribly awful! So I recommend buying the empty tablets and filling them. But needing to buy those empty tabs then makes this powder more expensive to actually use. Bulk Supplements says: "To create this supplement, our suppliers use Magnesium Oxide as a starting ingredient to produce Magnesium Glycinate. The process is designed to 'flush' the system so that no Magnesium Oxide remains; however, because it was used in the initial phase, we are required to list it on the label for transparency and compliance. Rest assured, the final product undergoes rigorous testing to ensure it is safe and of the highest quality. Our Magnesium Glycinate is 100% pure with no additives or fillers. The supplier does not "add" Magnesium Oxide as it is the starting source of the material itself. Based on the supplier's flow chart, there is leftover unreacted Magnesium Oxide content in the finished product, which is why we list it under "other ingredients". An exact percentage is not available. Even though Magnesium Oxide is part of the starting source it is required that we provide it to our label. We currently do not offer any other batches that are sourced from a different form of Magnesium." A web search explains how Magnesium Glycinate is created in a chemical process called chelation: "Magnesium oxide is chemically transformed into magnesium glycinate through a process called chelation, where magnesium ions are combined with glycine, an amino acid. This process involves dissolving magnesium oxide in an acidic solution, allowing the magnesium to bond with glycine, resulting in a stable and bioavailable compound known as magnesium glycinate. Transformation of Magnesium Oxide to Magnesium Glycinate Initial Form: Magnesium Oxide Magnesium oxide (MgO) starts as a solid mineral compound. It is created by heating magnesium with oxygen, resulting in a dry, chalky powder. This form contains magnesium bound to oxygen atoms and is not directly usable by the body. The Chelation Process Dissolution: Magnesium oxide is dissolved in a controlled acidic environment. This process breaks down the solid structure, allowing magnesium ions (Mg²⁺) to separate and move freely in solution. Binding with Glycine: Glycine, a simple amino acid, is introduced. Each magnesium ion binds with two glycine molecules, forming a stable chelate. This bond is crucial as it protects the magnesium from reacting with other substances in the digestive tract. Formation of Magnesium Glycinate: The final product is magnesium glycinate, also known as magnesium bisglycinate. This compound is more bioavailable, meaning it is easier for the body to absorb and utilize compared to magnesium oxide. Benefits of Magnesium Glycinate Higher Bioavailability: The chelation with glycine enhances absorption. Reduced Gastrointestinal Discomfort: This form is gentler on the stomach, making it suitable for sensitive individuals. This transformation from magnesium oxide to magnesium glycinate illustrates how chemical processes can enhance the effectiveness of dietary supplements. Wikipedia cymbiotika.com

Used to be pure magnesium glycinate, but now contains magnesium oxide which is useless as a supplement. They don’t state the ratio so it could be mostly oxide. They are trying to increase profits by cheapening the product. Glad I checked before reordering.

It does have a fishy smell but it is great not to have my muscles cramping on me.

Disgusting

FOUL tasting powder which takes away from enjoying this product for its intended purpose.

This product is mostly magnesium oxide, not glycinate. If you check the ingredients they'll tell you it's a mixture of glycinate and oxide without specifying the ratio. Glycinate is expensive while oxide is cheap, but practically useless unless you want to use it as a laxative. When you mix this in water, most of the mixture turns into clumps. Now glycinate is highly water soluble whiles oxide is not. This tells me most of what you get in this product is NOT magnesium glycinate and likely oxide or some other filler. This powder is only good as a laxative.
