    Thanks OP, bought 5 bottles. What do i use it for?

    • +15

      Good for your muscles. These ones are suppositories.

      • +13

        Everything is a suppository if you're brave enough!

      • Thank you. Any youtube instructions how to take these?

        • +1

          Not as many on YT as there is on Only Fans, so consult OF for more detailed instructions.

        • +1

          Stand on your head and chew one tablet thoroughly with some Doritos and wash down with bourbon.

      • I told my wife that you need to lick it first and I haven't seen her for the last 3 days.

    • +20

      Take 2 tablets at night, will help with sleep, feels like half the strength of melatonin.

      For me, I had awful leg cramps for years, bad enough to wake me up in the middle of the night feeling like I'd just been bitten by a fire ant.

      Physio recommended taking high dose magnesium right before bed, and getting more potassium in general as well.

      Tried a few brands and couldn't sleep because I was on the toilet instead, did a bit of research and ended up with random Magnesium Glycinate from chemist. Slightly better but still had stomach side effects, did more research and realised the one I got was still buffered so still mostly Magnesium Oxide (no truth in labels other than doing your own math), went down a rabbit hole and found Nature's Own Magnesium Glycinate as the only affordable high strength one that has no oxide in it at all.

      Haven't had issues since, the leg cramps return when I forget to take them for a few days, so I'm stuck with them now.

      • I had the same issue though any magnesium worked fine also going strength training at the gym for my legs helped a ton also for some reason.

        • +4

          Strength training made it worse for me personally, the night after leg day was usually torture, although I'm sure in the long term it has helped with increasing fatigue threshold (and has many other benefits of course).

          Years later I saw a dietician who mentioned that this was common for men who use protein shakes and bars while strength training, because the body uses a ton of magnesium to process dietary protein and the shakes never have enough of it to compensate compared to actual meat.

          So that plus the magnesium needed to actually build and repair muscles (mostly at night during deep sleep) basically creates a temporary deficiency, and so your body pulls magnesium from your muscles to keep levels stable, hence cramps.

          They can't detect this in standard blood tests either as that only measures free-floating magnesium which your body keeps stable by pulling from muscles. Wish I'd known this before starting strength training, would have saved years of sleep pain!

          • @Jolakot: Thanks that's good info ill keep that in mind thankfully I dont drink protein shakes or bars just eat actual meat as that's way more tasty haha.

            And yeah I still take the magnesium and stuff before bed plus I find they sometimes gave me really vivid dreams as a side effect which was cool =P

      • chelated magnesium is what my swimning coach recommended years ago, stopped my cramps whike swimming and when racing MTB.

        My gf takes it for legs cramps at night and says they work for her. Takes about 3-4 days to start.

        She uses this brand but Chelated.

        • Chelated is a lower grade than pure Magnesium Glycinate, basically if they could advertise it as Magnesium Glycinate then they would.

          It's typically a blend of citrate, glycinate and malate, almost always buffered with magnesium oxide, you rarely know what forms of Magnesium you're actually getting and how pure they are.

          • @Jolakot: Well ackshewally, a glycinate IS a chelate.

            Labelling is confusing. Magnesium chelate could include magnesium oxide which is less effective. It can also include mg glycinate.

            Like many supplement products, labels are only that, and there are no guarantees or treating that it is what you will get. Just like sunscreen :-)

            I don't use this product, and I've no idea if it's good or not.

      • Alcohol causes cramps.

      its great for making expensive urine from what ive read

      • +3

        So is alcohol, soft drinks, coffee, etc.

  • -1

    Alas you can't use this to prank your office…. For that you need Magnesium sulfate.

    • An excess of magnesium can cause diarrhea, so probably best to not be in the office tomorrow.

      • Just swap the office salt with this one… ;)

  • +10

    Wife reports these help her sleep better, not sure if placebo but even so it's worth the $22

    • I swapped to these from Bioglan; can't say I've noticed any real noticeable sleep difference.. But I was already on magnesium for forever so maybe if you weren't on it originally?

      • You won't notice a difference from Bioglan Magnesium Glycinate, because it's also pure unbuffered Magnesium Glycinate, wouldn't be surprised if they come from the same factory.

        It's just more expensive for the same dose/quantity, so the only difference you'll notice is in your wallet!

        • There is a small benefit of the bioglan, though, one tablet per day, this one requires 2 a day!

          • +3

            @ReaperX22: That's just marketing BS, the Bioglan has 160mg of magnesium per tablet, the nature's own has 150mg of magnesium per tablet.

              • +1

                @ReaperX22: Ah, yeah unfortunately Magnesium Glycinate is only 14% elemental magnesium at best, while something like magnesium oxide is closer to 60%, so you need to take signficantly more of the magnesium glycinate for the same amount of elemental magnesium

                Glycine itself is worth supplementing, so with magnesium glycinate you get 2 for 1 essentially, which is less annoying.

                • +1

                  @Jolakot: Isn't magnesium oxide absorbed poorly compared to other forms?

                  • @lbft: Yep, I'm not sure what the ratio is though

                • @Jolakot: Ah I see. Thanks for the info!

  • OOS already

    • Ah damn, will keep deal up as Coles has stock, wish I could change it

      • I stand corrected, back now so I picked some up thanks!

  • These are my go-to. The tablet is smaller than other brands as well which makes it easier to consume.

  • How does it compare ( quality wise ) to Healthy Care Magnesium Glycinate 120 Tablets @ $ 17.99 from CWH?

    Its Ingredients
    - Magnesium Glycinate 1.14g equiv. to Magnesium 160mg

  • +2

    Back in stock!

  • +4

    Just curious, OP mentioned: "not the crappy stuff you get from MagZorb".
    Looking at MagZorb it also has Magnesium Glycinate but at 500mg.

    How do we know if one is crappier than the other if they both contain mag glycinate and not mag oxide?

    • +2

      Yeah the OP is wrong with MagZorb. You can check the full ingredient list on the government website;

      https://www.ebs.tga.gov.au/servlet/xmlmillr6?dbid=ebs/PublicHTML/pdfStore.nsf&docid=328058&agid=(PrintDetailsPublic)&actionid=1

      Active Ingredients
      magnesium glycinate 500 mg
      Equivalent: magnesium 100 mg

      Other Ingredients (Excipients)
      calcium hydrogen phosphate
      colloidal anhydrous silica
      hypromellose
      magnesium stearate
      microcrystalline cellulose

      About the worst you can say about MagZorb is the lower effective dosage compared to some of the others… ie 100mg vs 150mg or 160mg.

      • +16

        You'd think so, wouldn't you? Like what you've said makes perfect logical sense, but unfortunately the TGA is anything but logical here with labelling laws (worth a whole other rant).

        Real quick, do some basic math with me. Magnesium Glycinate is maximum 14% elemental magnesium, it physically cannot go higher than that.

        Nature's own is 1150mg magnesium glycinate and 150mg elemental magnesium, about 14%.

        Vitaceuticals is 500mg magnesium glycinate and 100mg elemental magnesium, about 20%.

        You'll wonder, what kind of high-tech chemical breakthrough did vitaceuticals invent to break the laws of physics? They literally just dope it with cheap magnesium oxide to get the numbers up, that's it.

        I actually emailed them and asked because the numbers don't add up, you physically can't get 20% elemental magnesium from Magnesium Glycinate:

        When it comes to pure magnesium glycinate (with the molecular formula C₄H₈MgN₂O₄) you are correct that by mass the elemental amount of magnesium is approximately 14.1%.

        However, the magnesium used in MagZorb Magnesium Glycinate is not pure stoichiometric bisglycinate.

        Our product uses a manufacturer-specified Magnesium Glycinate 20% raw material, which is a glycinate-based, buffered magnesium system formulated to provide a higher analytically verified elemental magnesium content. The elemental magnesium level is confirmed by validated analytical testing (ICP-MS) rather than inferred from theoretical molecular weight calculations.

        They call it Magnesium Glycinate, but they add cheaper forms of magnesium to it as a way to cheap out on the raw ingredients. Hence it's a scam.

        • +4

          I asked the Google AI about this… "what is a glycinate-based, buffered magnesium system"

          And it seems to concur with your reply;

          How to Spot a Buffered System
          You can usually identify a buffered product by checking the Supplement Facts panel:
          Look for Oxide: If the label lists both "Magnesium Glycinate" and "Magnesium Oxide," it is buffered.
          Label Math: Pure magnesium glycinate is only about 10–14% elemental magnesium. If a 500mg capsule claims to have 200mg+ of "magnesium glycinate," it is likely buffered with oxide.

          Score board:
          Jolakot: +1
          TGA: -1

        • I like the way Swisse reports their Magnesium content (which I currently use)… "MAGNESIUM (from magnesium glycinate) 150 mg" and thats it. You don't have to do any math to try to work out if they are diluted or not. Still more expensive than Nature's Own.

          edit: and its same label reporting from Nature's Own, but very different from MagZorb.

          • +2

            @RnR: Swisse magnesium glycinate is fine, math works out.

            But you have to go to their TGA listing to work out how much magnesium glycinate is actually in the product, they only list elemental magnesium on the packaging, which is poor labelling imo.

    • +1

      I belive this comment explains their views: https://www.ozbargain.com.au/comment/17296090/redir

  • What's wrong with magZorb?

  • +1

    Back in march. It was 17.79 back , may be due to inflation

  • Thoughts on Thorne and Now as compared to these?

    • +1

      Hard to tell, I don't trust US labels as they're not legally required to specify quantities of active ingredients, they'll just list total elemental magnesium without saying how much from what, so can't do the math to check.

      Either way they seemed like 4x the price per tablet compared to nature's own so why bother?

      • Ohh didn’t know that, thanks for thatS I know very little about these things so my minds going “it will be good if its expensive” .

      • But US labels also have other ingredients which Australian supplements aren't required to label. For example, iHerb have Swisse on there and they always have things like: Microcrystalline cellulose, polyvinyl alcohol, calcium phosphate, titanium dioxide, crospovidone, polyethylene glycol, magnesium stearate, talc, calcium phosphate dibasic, silicon dioxide, maltodextrin, sodium copper chlorophyllin (color), croscarmellose sodium, spearmint oil (flavor), carnauba wax.

        On their Australian counterparts, that's not listed.

        So what's in the other ingredients for Nature's Own Magnesium Glycinate?

        The one I use is Doctor's Best, High Absorption Magnesium Lysinate Glycinate, however, I do use Nature's Own Magnesium Glycinate when I run out.

        • +1

          They're required to disclose that stuff in Australia too, but only in TGA registry not on label:

          calcium carbonate, colloidal anhydrous silica, povidone, croscarmellose sodium, crospovidone, Flavour, hypromellose, macrogol 3350, magnesium stearate, maltodextrin, medium chain triglycerides, microcrystalline cellulose, polydextrose, polyvinyl alcohol, purified talc

          I wish that was the case here as well.

  • I need methycobalamin deal as well

  • +1

    same price at Coles for anyone looking

  • So taking two would mean it's a 100day supply for ~$24

    How's this one then? https://www.amazon.com.au/dp/B0BWQQGPSR

    Says 500mg is that just marketing? I can't find more info on it.

    • It's just expensive for what it is, paying close to premium prices for bottom-tier ingredients. Can get 200 one a day tablets for closer to $20 if you don't care about purity and don't have stomach issues from it, just search for "magnesium 1000mg".

      Most of that 500mg would be from Magnesium Oxide, which is 60% magnesium but bad absorption and harsh on stomach. They say premium forms of magnesium on label but they'll all be significantly buffered with cheap oxide, and you can't do the math to work out how much with these types of blends.

    • Looks like the magnesium is boosted by taurate, citrate and malate which aren't absorbed as easily by the body.

      The better quality supplements don't tend to include other supplements as discerning people tend to closely manage the quantity of each supplement.

  • -7

    This is useful for people who don't eat any food.

    • Most people get enough through diet and don't need this, but you can certainly benefit from having more of it than you need.

      Like someone earning $60k has enough to live on, old studio apartment, homebrand food, cheap TV etc. They have enough, doesn't mean they wouldn't benefit from an extra $100k though, does it?

      • Nice analogy! I like it.

  • How do these compared to that brand Renew?

    • +2

      Renew is worse in literally every way, notice how they don't tell you how much magnesium glycinate is actually in it? It's what they don't tell you that matters most.

      Physically impossible to get 200mg worth of elemental magnesium in a single capsule (they're standard sizes) without it being buffered with cheap magnesium oxide. Either they've broken the laws of physics or they're cheating you.

      More expensive too, why bother.

      • -1

        I get what you’re saying, and I do think it’s a fair concern in general because a lot of magnesium supplements are marketed in a confusing way. Some brands put “magnesium glycinate” on the front, but when you look closer, they’re either talking about the total compound weight rather than the actual elemental magnesium, or they’re using a buffered blend with cheaper forms like magnesium oxide.

        That said, I don’t think it’s fair to automatically assume Renew is making a false claim without looking at the full back label. I actually have the bottle here, so I’m not just going off the Amazon listing. I agree the Amazon listing itself doesn’t show all the information clearly, which is annoying, but the information I’m referring to is from the physical bottle itself.

        The back label on the Renew bottle states:

        Magnesium as magnesium glycinate: 200 mg per capsule

        It also gives a recommended dose of 2 capsules daily, which is where the front label gets the 400 mg per serving claim from.

        So the label is not just vaguely saying “400 mg magnesium glycinate” or only listing the compound weight. It is specifically claiming magnesium as magnesium glycinate, 200 mg per capsule. That’s an important difference, because with magnesium supplements the wording matters a lot. Some brands list the total compound weight, which makes the dose look much higher than the actual elemental magnesium amount. But on the bottle I have, Renew is wording it as magnesium provided as magnesium glycinate.

        I do agree that 200 mg elemental magnesium from glycinate in one capsule is a high claim, and that’s why I understand the skepticism. Magnesium glycinate is a bulky compound, and with true unbuffered glycinate/bisglycinate, the actual elemental magnesium percentage is much lower than the total compound weight. So yes, from a formulation point of view, it’s reasonable to question whether the capsule is very large, densely packed, or whether there’s some detail missing.

        But the key point is that the actual bottle label does not list magnesium oxide as a medicinal ingredient. It only says magnesium as magnesium glycinate. The non-medicinal ingredients listed on the bottle are also very basic:

        Cellulose capsule, rice flour, silicon dioxide

        Those are normal inactive ingredients … the capsule shell, a small filler/flow agent, and an anti-caking agent. From what I can see on the physical bottle, there’s no magnesium oxide, citrate, carbonate, or any other cheaper magnesium form listed. That’s why I don’t think it’s fair to automatically assume it’s a buffered oxide blend unless there’s actual evidence for that.

        Also, Renew appears to be a legitimate Canadian product, not some completely unknown random bottle. It has an NPN number on the label, meaning it’s registered as a Natural Health Product in Canada. That doesn’t mean every Amazon listing is perfect or that consumers should never question labels, but it does make it very different from some no-name supplement with no proper regulatory listing.

        The comparison with Nature’s Own is interesting because Nature’s Own is more conservative and arguably more believable on the dose. Nature’s Own clearly states:

        Magnesium from magnesium glycinate: 150 mg per tablet

        That is very straightforward and realistic. It’s also an Australian-made product from a well-known mainstream Australian brand. The only thing I noticed on that one is that it says contains sulfites, which are commonly used as preservatives or can be present from ingredients/manufacturing. Not necessarily a big deal for most people, but some people are sensitive to sulfites.

        So my take is this:

        I wouldn’t say Renew is definitely dodgy just because the dose looks high. The actual bottle I have in front of me clearly claims 200 mg magnesium as magnesium glycinate per capsule, and it does not list oxide. It’s made in Canada and has an NPN number, so there is at least some regulatory framework behind it.

        But I also wouldn’t dismiss the concern completely, because 200 mg per capsule from pure glycinate is unusually high compared with many other glycinate supplements. So the real question is not “does the label say it?” because the physical bottle clearly does. The real question is whether the product is truly unbuffered magnesium glycinate and whether the formulation is exactly as clean as the label implies.

        Between the two, I’d probably say:

        Nature’s Own is the safer and more conservative choice if someone wants a mainstream Australian product with a very clear, realistic dose.

        Renew looks stronger and cleaner on paper, especially with only cellulose, rice flour, and silicon dioxide listed as inactive ingredients, but the high 200 mg per capsule claim naturally invites more scrutiny.

        So I think your concern is valid as a general warning, but I wouldn’t go as far as saying Renew is making an impossible or false claim unless there’s evidence that it contains oxide/buffered magnesium or that the NPN details contradict the label. The Amazon listing could definitely be more transparent, but the bottle itself gives more information than the listing does.

        • +2

          You may need to upgrade your chatgpt plan mate, because it missed one very very obvious thing, basic math.

          Say it's pure magnesium glycinate, at 14% that 200mg elemental magnesium is 1428mg magnesium glycinate.

          Chuck this into your AI and tell me what it says: "can you fit 1428mg of magnesium glycinate in a single capsule"

          Because it just isn't possible, not even the largest 000 size tablet could hold that much, even without adding binders and stabilisers to the mix.

          The tablet would have to be the size of a double AA battery! You've got them in front of you, are they the biggest tablets you've ever seen, can you swallow them?

          So what's more likely, they broke the laws of physics, or they're using a buffered blend?

          They don't have to list magnesium oxide on the label for a buffered blend, it's a huge gap in our labelling system. Same with the vitaceuticals MagZorb, they themselves admitted it's buffered but you'll find nothing but magnesium glycinate on the label or TGA listing.

        • I get what you’re saying,

          But the key point is that the actual bottle label does not list magnesium oxide as a medicinal ingredient.

          I don't think you get what he's saying.

          The way labelling laws work means they don't have to list magensium oxide as an ingredient. The maths demonstrates that its impossible for them to actually fit "200 mg magnesium as magnesium glycinate" in the capsule. Just like magzorb they're including cheaper magnesium compounds in the capsule but not disclosing it on the label.

          The amount of elemental magnesium can not be more than 14% of the total weight of the magnesium glycinate in the pill.

    I was a non-believer with this stuff but can report that it helped quite a bit with my neck pain and general ability to go to sleep. Strongly recommend.

  • i currently take Webber Naturals Magnesium 250mg 150 Tablets, does anyone know if this one is better? i dont get muscle cramps much anymore since taking the mag but ive heard good things about this variant.

    I used to also take another brand that gave me elevated levels of vit B6 which was worthless since i already get plenty of B6 from my food intake (if anything my b6 levels were too high and it was posing a risk to my health, its since dropped after i threw the old pills away and replaced with Webber), this one looks like pure mag like the webber one im taking so should be fine?

    • +1

      Webber Naturals Magnesium 250mg 150 Tablets is magnesium oxide (check the back of the bottle - it states Heavy Magnesium Oxide) :/

      You can check absorption here

      At best, you body absorbs 4-15% (lets say 10% average) of magnesium oxide, so out of that 250mg dose, you are getting 25mg at best (just have an avocado instead for ~ 58 mg of magnesium) :P

      Not to mention the "oxide" tends to be much more rough on the GI (commonly resulting in diarrhoea for some people)

      • ironically its already working quite well for me, noticeably too.

        I used to suffer from cramps every night in my leg but they're gone (mostly anyway, maybe 1 cramp a month, and it went away went i took the mag citrate/oxide). given the subpar absorption of the mag oxide compared to the increased potential of Magnesium Glycinate, this product may give me some noticeable benefits.

        Checked out your link also, with this product i would have tried citrate, oxide, and now glycinate (its getting delivered tonight). Glycinate looks like a clear winner.

    • The Webber one is magnesium oxide, which is the cheapest and most dense form, but it's also the worst for your stomach and least absorbable.

      This one will be better if you experience any stomach issues after taking it, and in general is higher quality.

      • I have no stomach issues but i have reaped some noticeable benefits on the oxide (and citrate variants that ive tried also), i cant wait to start on the glycinate, easier on the stomach AND better absorption sounds incredible

  • This have any hidden b6? I used another brand and ended up getting b6 toxicity

    • Nope, pure Magnesium Bisglycinate ;)

  • +1

    Magnesium L-Threonate or L-Theanine . Is what I take . And I'm the best !

    • L-Theanine is great, I like Magnesium L-Threonate but find it's too stimulating to have at night, but too calming to have during the day, so haven't really found a spot for it

    • Could you recommend some brands please?

  • +1

    Given all the info above around purity and mislabelling, can anyone recommend the best commonly found brand of magnesium glycinate that comes in powder form?

    • https://www.coles.com.au/product/swisse-ultiboost-magnesium-…

      1/2 price too! Well just for tomorrow :)

      • Working my way through some of this at the moment - this "unflavoured" version (which the TGA website says still contains flavour) makes you realise why Swisse put flavours in their other powders, it's a very…interesting…taste and pretty hard going without adding a mixer.

  • This stuff is awesome, particularly for anxiety, restlessness and sleep quality.

  • After cycling through a few brands and formulations, I'd landed on nature's way 1000mg (200mg equiv) amino acid chelated magnesium https://www.amazon.com.au/Natures-Way-Magnesium-Chelate-Kilo… 3x a day for leg cramps and jaw clenching from vyvanse . Other brands/compositions either didn't do much, or made my poop loose.

    I've bought a few bottles of this deal, will be interesting to see how it compares. The nature's way are also horse tablet sized so annoying to fit in compact pill boxes!

  • Usually dispatched in 1 to 2 months! WTH

  • The tablets are quite large.
