Mast Cell and Histamine Safe Forms of Magnesium: What to Know When You Have Mast Cell Activation Syndrome or Histamine Intolerance

Did you know that low magnesium levels are often a problem with Mast Cell Activation Syndrome and Histamine Intolerance?

And without enough magnesium, it can be very hard to get healthy again.

Magnesium was one of the first supplements I learned about. I knew about its importance for years. But I had trouble navigating all the different forms.

And two forms made me way worse when I wasn’t sure what I was doing. These forms were magnesium citrate and magnesium sulfate (Epsom salts).

Magnesium citrate made me itch all over and I couldn’t sleep.

And when I tried Epsom salts, I started way too high for me at 1 cup. I had horrible joint pains. I had burning urination. And I felt extremely agitated and moody.

I’ll explain why I had trouble with both of these forms in a bit. And why you may find yourself having this trouble if you’re sensitive like me.

It actually took a while for me to sort through all the information and figure out the pros and cons of these different forms of magnesium.

And about 50% of the people I see in my Mast Cell 360 practice are making the same mistakes I was making years ago.

So, I want to help you avoid the problems I had by sharing what I learned with you.

Especially because not all forms of magnesium are helpful with Mast Cell Activation Syndrome or Histamine Intolerance! So, you want to know what to watch out for.

These days, I make sure to supplement with magnesium each and every day. And I take it in a few different forms.

That’s because without enough magnesium, it can be very hard to get healthy again.

For example, without enough magnesium, it can be hard to get your histamine levels in check.

You’ve probably heard of one form of magnesium – Epsom salts. But did you know that Epsom salts are actually a type of magnesium? This form of magnesium is magnesium sulfate.

Magnesium sulfate is just one of the many forms of this important mineral.

But with all the different forms of magnesium available, it can be confusing to know where to start. And not all forms of magnesium are safe when you have Mast Cell or Histamine issues.

I want to share the importance of getting your magnesium levels up. And I also want to share which magnesium forms may be helpful for Mast Cell Activation Syndrome and Histamine Intolerance.

Plus, you’ll learn which forms of magnesium you might need to be careful about using if you have Histamine Intolerance.

First, let’s look at the importance of magnesium for overall health. Then we’ll look at its importance specifically for Mast Cell Activation Syndrome and Histamine Intolerance.

Why Magnesium is Important

Why is magnesium so important? 

It’s because over 300 enzyme reactions in the body use magnesium to work! That’s quite a lot!

Magnesium is needed for:

  • Mast cell and histamine support
  • Cardiovascular health
  • Muscle function
  • Good digestive function
  • Energy production
  • Regulating nerve function
  • Regulating blood sugar levels
  • Regulating blood pressure
  • Making protein
  • And more

Magnesium is key for so many systems in your body. It helps them work the way they should.

For example, you likely can’t keep your histamine levels low and take care of your mast cells well if your magnesium is low.

And, according to data from the National Institutes of Health, low intake of magnesium over time increases your risk for illness.

So, it’s vital that we get our magnesium up to healthy levels.

Low Magnesium Levels are Common

Low magnesium levels are more common than most people think.

Here’s something else you should know about magnesium. It’s an essential nutrient. That means our body can’t make it. We have to consume it in food sources or in dietary supplements.

A long time ago, we got enough magnesium through what we ate. But today our soil doesn’t contain the minerals it did in the past. Plus, the average diet isn’t as healthy as it used to be. So, it can be hard to get enough magnesium.

In 2018, it was estimated that up to 45% of Americans had low levels of magnesium. This is because of a few different reasons.

Research has also shown around 60% of Americans don’t eat enough magnesium-rich foods anymore.

And even if you eat low histamine, high magnesium foods, like green leafy vegetables or pumpkin seeds, generally only about 30% to 40% of dietary magnesium is absorbed from food sources.

Since soils have become more depleted of magnesium, there isn’t as much magnesium as there used to be… even in high magnesium, organic foods.

Plus, your magnesium levels can become low due to various health conditions like:

  • Inflammatory gut issues
  • Excessive urination or sweating
  • Pregnancy and lactation
  • Diabetes
  • Hyperthyroidism
  • Hyper- and hypoparathyroidism
  • Excess estrogen
  • Heavy menstrual bleeding
  • Too much calcium supplementation
  • Vitamin D being too low or too high
  • Too much phosphorus from soft drinks
  • Certain medications affecting absorption, such as proton pump inhibitors like Nexium or Prilosec, antacids, diuretics, and antibiotics
  • Low B6 levels
  • Alcoholism

So, you might not be getting enough magnesium through food sources. Or you might not be absorbing enough magnesium due to health conditions.

Either way, you’ll likely want to get your magnesium levels up if they are low.

But how do you know if they are low? Let’s take a quick look at that.

Testing Magnesium Levels

How can you know if you are low? First off, don’t look for a magnesium serum test to tell you how good or how low your levels are. Magnesium doesn’t stick around in the bloodstream for long. So it’s not the best marker.

The best way to check magnesium levels is usually considered to be a different test called the magnesium red blood cell. It’s much more reliable than the more commonly used serum magnesium marker.

TIP: You can purchase a Magnesium Red Blood Cell test on your own and get it drawn at Quest. Here’s where to get it, just type Magnesium RBC into the search field at: Ulta Labs to order your Magnesium, RBC test.

As we talked about, magnesium has an important role in the body’s ability to stay healthy and to heal.

And it also plays an important role if you have Mast Cell Activation Syndrome or Histamine Intolerance. We’ll cover that next.

Role of Magnesium as a Mast Cell Support

Magnesium has an important role when it comes to mast cells and histamine.

It helps support DAO levels by reducing the amount of histidine (an amino acid) that gets converted to histamine.

In an animal study, researchers found 4 days of low magnesium intake caused histamine to rise quickly. and it kept getting worse. The animals’ histamine levels went super high by day 8.

But when magnesium was added back, histamine levels went back down again.

Magnesium deficiency was also linked in studies to an increase in mast cells in certain organs. Specifically, mast cells went up in the liver, small intestine, kidneys, bone marrow, and kidneys in rats.

In a mouse model of colitis, magnesium-rich mineral water significantly reduced inflammation in the gut. And as you probably know by now, there are huge numbers of mast cells in the gut that can drive gut inflammation when triggered.

You also probably know that toxins can trigger mast cell activation. But a specific type of magnesium can support detoxification. This form is called magnesium sulfate, found in Epsom salts.

So, as you can see, there are a lot of different ways magnesium can support your mast cells and histamine levels.

It’s good to use more than just one form of magnesium though. Let’s look at why in the next section.

Importance of Using Various Forms of Magnesium

Using a variety of forms of magnesium can be really helpful. That’s because different forms of magnesium are good for different things.

For example, some forms of magnesium are really great for constipation.

One form of magnesium is really great to take in the morning for energy.

Another form is great to take at night for sleep.

So, one size doesn’t fit all when it comes to magnesium.

Another important thing to consider is whether you want to use magnesium orally or topically.

If you have gut problems where you aren’t absorbing magnesium supplements very well, you may want to add a topical version.

Topical magnesium goes directly through the skin and skips the gut. So, you might be able to absorb more magnesium using a topical form if you have issues like SIBO.

You’ll learn about good topical and oral magnesium supplement options in just a bit.

But first, I want to let you know about a couple of high histamine magnesium forms to avoid. 

High Histamine Forms of Magnesium

There are some high histamine magnesium products. And they may trigger Histamine Intolerance or Mast Cell Activation. So, I want to make sure you know about them. 

Take a look at this list below for forms of magnesium you may want to avoid if you have Mast Cell Activation Syndrome or Histamine Intolerance.

Magnesium Citrate

This form of magnesium is frequently used to combat constipation.

But it can have some unwanted side effects for people with MCAS or Histamine Intolerance.

The problem you may have is that this dietary supplement comes from fermentation. For that reason, it’s a higher histamine magnesium.

Some people do fine with this in very small amounts in some products, though, as opposed to the large amounts in a normal magnesium citrate product.

For example, it seems to be well tolerated in Steve Wright’s enzyme supplement, HoloZyme™. It just depends on your level of sensitivity as well as the amount.

Other Magnesium Supplements

Magnesium products with other mast cell triggers can be another problem.

Watch out for mast cell triggering additives and preservatives like:

  • Titanium dioxide
  • Potassium sorbate
  • Sodium benzoate
  • Flavoring agents
  • Coloring agents

Other than magnesium citrate and additives, most forms of magnesium should be low histamine as well as mast cell and histamine supportive.

Be sure to check those labels, though!

We’ll cover some great low histamine forms of magnesium to look for next.

It’s important you know that this blog post is for informational and educational purposes. It’s not meant to treat any health condition or to be prescriptive for anyone. Always be sure to work with your healthcare provider. I highly recommend trying all new supplements slowly to make sure they are ok for you.

Low Histamine Forms of Magnesium

Let’s look at both oral and topical magnesium options.

You’ll learn some uses for each. And you’ll be able to see which have specific pros and cons.

I’ve included links to Fullscript below. This is a great place to get supplements because they are very strict about quality control.

No matter where you buy your supplements, you want to make sure that you get them from a source that is temperature controlled and buy brands that are both good quality and contain what they say they do!

There have been counterfeit and quality issues getting supplements through Amazon for quite some time, so beware. Some supplements were found to be counterfeit and have high levels of heavy metals or other toxins… and none of the actual claimed active ingredients.

Ok, so let’s start with forms of magnesium that are taken orally.

Oral Magnesium Supplements

The following are low histamine oral forms of magnesium.

Magnesium Glycinate

Magnesium glycinate is generally considered to be a really well absorbed type of magnesium. So, it can be a helpful form if you’re dealing with a leaky gut. It’s also usually calming and helpful as a sleep aid.

However, in some people, the glycine in magnesium glycinate can end up converting to more glutamate. This can be a problem in those with high glutamate.

High glutamate can show up as anxiousness, sleep issues, and trouble with attention.

It can be stimulating if that’s the case. So, I always recommend you start supplements slowly to see if they work for you.

For a supplement, you can look into this Magnesium Glycinate by Pure Encapsulations


Magnesium Oxide

Magnesium oxide is a good option for stubborn constipation for people who are very sensitive to magnesium supplements.

This is because it’s not well absorbed. So, for some sensitive to magnesium this may be the only form that works for them.

The downside, though, is again, that it’s not well absorbed. So, it won’t raise magnesium levels in the body.

But this is often the starting point I suggest for sensitive people dealing with constipation until they can tolerate better absorbed forms.     

I like this Magnesium Oxide by Douglas Labs

Magnesium Malate

Magnesium malate can be helpful for muscles and energy production.

I used to think malic acid was a histamine liberator. But I haven’t found enough evidence, so I’ve taken that information off the website for now.     

This is the Magnesium Malate from Douglas Labs is the one I use in the clinic.

Magnesium Taurate

Magnesium taurate is another form of magnesium that can help support detoxification. It does this by supporting glutathione levels, a very important antioxidant and detox compound.

Magnesium taurate can also help with bile production. Bile production is important for eliminating toxins and digesting fats.

Magnesium taurate is a form that can be beneficial for heart health, too. This is because the heart is dependent on taurine found in magnesium taurate.

However, this form may not always be well tolerated early on by people who are really sick from Mold Toxicity or chronic bacterial or viral issues.

This Magnesium Taurate from Cardiovascular Research Ltd is one I like when the timing is right.

Magnesium Threonate

Magnesium threonate is the only form of magnesium seen to cross the blood brain barrier.

Because it crossed the blood brain barrier, it’s often a good form for any brain condition.

It can also help with sleep issues and occasional anxiousness.

And magnesium threonate usually doesn’t cause loose stools like other forms of magnesium.

This is one brand that I like: Protocol for Life brand Magnesium Threonate

Magnesium Chloride

Magnesium chloride can come in either an oral liquid form or a topical form. Here we’ll look at the oral, liquid form.

In liquid forms, it’s hard to find one without potassium sorbate and sodium benzoate as additives. So be sure to check those labels!

Concentrace Trace Mineral Drops have a good amount of magnesium chloride without the mast cell triggering preservatives.

It has some trace minerals though. That can be problematic for some people.

Like with everything else I’ve mentioned here, it’s often best for sensitive people to start very slowly.

Magnesium Orotate

Magnesium orotate is a well absorbed form. However, it’s not frequently available.

It has shown potential to help the heart and energy levels.

I prefer this Priority One Magnesium Orotate

Next, let’s look at some forms of topical magnesium.

Topical Magnesium Supplements

Topical options most often include:

  • Magnesium chloride
  • Magnesium sulfate

Magnesium chloride is good for muscle relaxation, while Epsom salts, magnesium sulfate, are good for helping with detoxification.

Let’s look at those next. Along with some recommendations for mast cell friendly sources.

Magnesium Chloride

We already talked about the pros of magnesium chloride. So, let’s look at some different topical forms.

Magnesium chloride flakes, like these ones from Ancient Minerals, are great for putting in the bath. It can help to relax muscles and calm down before bed.

Ancient Minerals Magnesium Chloride Flakes

Or you can also use the Trace Minerals Magnesium Chloride Flakes from Fullscript. Either one is good.

You can also get magnesium chloride in a lotion or spray form. This can sting a little if your skin is sensitive. But you can dilute it with any moisturizer you tolerate. Be sure to patch test a small amount if you have sensitive skin,

The spray or lotion can leave a slight salty film on the skin. It can be washed off after 20 minutes.

Now Magnesium Spray is a magnesium spray I like.

Or you could try a gel, if you prefer, like MagneGel from Designs for Health

Magnesium Sulfate

Magnesium sulfate is actually a form of magnesium commonly known as Epsom salts. Magnesium Sulfate supports detoxification and even helps get rid of oxalates.

Epsom Salts

Watch out for added fragrances. Those can also be a mast cell trigger. For example, the Whole Foods brand has artificial fragrances.

Definitely go slowly with Epsom salts! Many people start way too high. You can start with as little as ½ tsp in a foot soak.

And here’s something you need to know about Epsom salts. They aren’t right for everyone.

Those who have issues with oxalates may not tolerate higher amounts of Epsom salts.

It’s almost always a good idea to start supplements and changes low and slow, but especially so with magnesium sulfate. Let’s take a quick look at why and how to start slow.

Starting Magnesium Sulfate Slowly

Remember we talked about magnesium sulfate supporting detox earlier?

That can be a really good thing. But if you start with too much, Epsom salts could cause stored toxins to dump into the bloodstream too quickly. Again, that may be too much for your body to process. That’s what happened to me.

When I was still really sick, I tried using Epsom salts. I started with a cup in the bath. I thought that amount would be fine. But it was waaaay too much for me.

It caused me massive pain and burning urination. I had so much irritation and moodiness, I actually felt like punching through walls… except I didn’t have the energy.  It was kind of scary.

These reactions from Epsom salts all made sense when I finally learned about oxalates and sulfates!

I had too many oxalates in my body and the Epsom salts were pushing them out too fast.

That can be due to the Epsom salts causing stored oxalates to suddenly dump into the bloodstream.

Another problem I had back then was that I had a lot of toxins in my body. Especially mold toxins. 

Related Post: How to Detox Your Body Gently from Mold

I kept failing with Epsom salts and flaring myself up until I figured out these connections. That’s why I want to stress to you to start slowly and gradually build up if you have any of these issues.

I started over with a teaspoon of Epsom salts in a bath and very slowly increased it over a year. 

If you really cannot tolerate Epsom salts, some clients start with magnesium chloride flakes. These are not as helpful with oxalates. They are gentler though for people with a lot of oxalate dumping.

Not everyone has trouble with Epsom salts, though.

And for some, magnesium sulfate is a game changer. Especially with Salicylate Intolerance.

The great thing is that each form has different uses and benefits. I’ll go over my personal use next. And I’ll offer you some suggestions on where you might start.

What Magnesium to Use

woman asking questions

After reading about all those amazing magnesium supplements, where do you start? Which magnesium should you use? It’s really all about what you want help with and what your body can tolerate. 

If you have constipation and are sensitive to supplements, you could consider starting with Magnesium Oxide. But add it in very slowly.

Epsom salts (magnesium sulfate) can be very helpful for salicylate intolerance.

If you’re very sensitive or have a lot of mold toxins, you could start as small as a pinch of Epsom salts (magnesium sulfate) in a bath.

Or a little drop of magnesium chloride spray on your skin.

I personally use multiple forms. For example:

But what if you aren’t tolerating any magnesium at all? What if you’re having trouble with a lot of supplements?

In that case, you’ll want to work on your nervous system first in the Mast Cell Nervous System Reboot.

  1. Marie

    Thank you for this very informative blog post. I was just thinking that I needed to add more magnesium, perfect timing 😃

    1. Suz, Mast Cell 360 Team

      Great! Thanks for letting us know the blog post was helpful!

    2. Catlin

      Is designs for health magnesium malate a better tolerated option?

      1. Jamie, Mast Cell 360

        Yes, Magnesium Malate can be helpful for muscles and energy production and the Designs for Health does not have fillers that cause typical reactions for those with MCAS. With that said since we are unfamiliar with your individual case, we cannot say for certain if this particular supplement will or will not work for you.

  2. Olga Y

    I attempted to order Magnesium Red Blood Cell test and went to the suggested link ( ) and typed “Magnesium Red Blood Cell test” in the search box and the answer I’ve got was “no results found”. Am I doing something wrong?

    1. Suz, Mast Cell 360 Team

      Hi Olga,
      Thanks for letting us know. It looks like you have to search Magnesium, RBC now. I’ve updated our blog post to reflect this. Thank you again for bringing this to our attention!


      1. Olga Y

        Thank you Suz! I can find it now! It states that patient should refrain from taking vitamins, or mineral herbal supplements for at least one week before sample collection. Is this recommendation specifically about magnesium?

        Thank you so much for this article. I’ve been taking magnesium malate before bed. It’s good to know that its better to take it in the morning and take another kind at bed time.

        1. Suz, Mast Cell 360 Team

          Hi Olga,
          We contacted the testing company, and they said that it means all vitamins and herbal supplements. We recommend talking with your practitioner before stopping use of anything.

          Best regards,
          The Mast Cell 360 Team

  3. Laura

    Thank you, this post is great, a lot of useful information. Even I am extremely reactive to supplement I am doing well with magnesium citrate. But have terrible reaction from Epsom salt even tiny amount caused burning sensation in my mouth. Now I am considering to try out some other forms of magnesium.

    1. Suz, Mast Cell 360 Team

      Hi Laura,
      Thanks for letting us know the article was helpful!

  4. Jo

    How do you know how much to take of each? I always start low and build up.

    1. Suz, Mast Cell 360 Team

      Hi Jo,
      You can check the label for recommended dosage or talk to your practitioner. It’s different for everyone. Great to hear you start low and slow!

      Suz, MC360

  5. La

    Thank you for this very detailed listing of magnesium options. I have been experimenting with types of magnesium for one year. Wish I saw this article sooner it is very helpful but with suspected mast cell syndrome, histamine intolerance, sensitivity to salicylates, high oxalates and sulfur allergy, (after years of chronic illness, antibiotic use and leaky gut clearly), it has been hard to find the right magnesiums. Taurate and Threonate forms seem best for me so far but I have so much more information now thank you.

  6. Sue

    Hi, thank you for this post! I have been taking Magnesium Carbonate and don’t seem to have a reaction. Can you comment on this form?
    Thank you!

    1. Suz, Mast Cell 360 Team

      Hi Sue,
      I believe Beth will touch on that form just a bit in her upcoming mold course. But one thing she says is that if something is working for you and not causing a reaction, that’s great. Everyone is different in what they can tolerate so listen to your body.


    1. Suz, Mast Cell 360 Team

      Hello! Beth said she hasn’t used it much herself, but it can be an option. Since we don’t know your case, we can’t say for sure if it would be right for you, so be sure to talk with your provider with any questions or concerns.

      Best regards,
      Suz, MC360

  7. Lily

    Hi there. What is your take on solar urticaria and histamine? Do you think magnesium supplement might help doing away with this reaction?

    1. Suz, Mast Cell 360 Team

      Hi Lily,
      If you mean rashes triggered by sun exposure, you can consider a few different options. There isn’t just one supplement that would address it. Rather, you’d need to look at how to support yourself and your mast cells. We do this by addressing mast cell triggers, lowering histamine, support mast cells with different supplements and nervous system supports. These are just a few options that may help calm the mast cells. You can learn more in the Mast Cell 360 courses which can be found here:

  8. Steve

    Is it OK to take Magnesium Malate at bedtime? I tried Threonate but oddly it made me too alert.
    I also see a product from Seeking Health that contains Magnesium Malate and Magnesium Glycinate/Lysinate.
    It does contain ascorbyl palmitate as a filler.
    What do you think of this one? Thanks

    1. Suz, Mast Cell 360 Team

      Hi Steve,
      Magnesium malate tends to be energizing, so using it at bedtime may not be the best time of day to consider it. Magnesium glycinate is one that Beth does take at bedtime. This is the one she likes:
      This is also the one she uses in the practice. Unfortunately, we aren’t able to review individual products, but the ones we recommend, Beth has tested them herself, looked into them extensively, and would recommend to clients.
      We can’t say what may be right for you without knowing your case, so please be sure to talk with your provider with any questions or concerns.

      Thanks for your interest in Mast Cell 360!

  9. Veronika


    Thank you very much for your know-how and experience! Your website is really great! I am very happy you share all this with us.

    I would just like to add, that Magnesium taurate could cause insomnia, as it’s also high in taurine. Perhaps it is good to mention it because people could confuse a sleepless night after taurine supplements with activation issues…

    I must say I had disastrous migraines, or maybe better said, brain pains, after taking any form of magnesium so far, even without any additives etc., so I am very happy you take magnesium supplements so seriously, there are also some new things here for me. This is really funny, as when I was looking for the correlation between magnesium and headache on the internet, obviously, I always found only how great is magnesium for curing 🙂 headache.

    I am not sure about converting glycine to glutamate in the body. Personally, I use glycine to boost glutathione levels before sleep and it works great as it actually stabilizes (!) glutamate. So perhaps, glycine i magnesium glycinate could work the same way? Or there are some other chemical reactions?

    1. Jamie, Mast Cell 360 Team

      Hi Veronika, Some people have trouble with taurate and others do just fine. For some, magnesium glycinate is very calming, for other it’s overstimulating. This is why we recommend everyone start with sprinkles and go slowly when trying anything new.

  10. Krystal

    Hi! I saw Beth uses malate, concentrate, threonate, and glycinate daily as far as the oral forms. Does she take the full doses on the bottles for each daily? That would be 300 mg for mag malate, 144 mg for mag threonate, 510 mg for mag glycinate, and 250 mg for the concentrate for a total of 1240 mg magnesium per day. Just wondering if she takes this full amount and if that type of dose is common in people who run chronically low as well as the mast cell community or if she only takes partial doses of each one. I know you can’t recommend specific dosing for individuals and you are not prescribing or giving medical advice if you share that information. I’m just confused because of the dosing and what she says she uses for products. I track my rbc magnesium monthly which may be too often. I imagine she uses that as well. Thank you so much!

    1. Jamie, Mast Cell 360 Team

      Hi Krystal, in order to know which dosing of magnesium to take we recommend discussing with your licensed medical provider as your needs may be different than Beth’s.

  11. A.M.

    Hi, have you ever done a post on forms of calcium that are good for MCAS? I’ve been taking calcium citrate but I’m realizing that almost anything with citrate is made via fermentation. I have very severe mcas, I’ve lost so much weight I stopped menstruating and I’m trying to identify my triggers which seem like everything right now. I’m trying to figure out if some of my supplements maybe causing problems. Do you have a recommended form of calcium for those of us who don’t get enough in our diet and have sensitive guts?

  12. Elisabet

    Just read Magnesium Threonate is illegal in EU where I live :/
    Is the body really able to absorb enough magnesium from lotion? Cause its sounds like a good alternative if you have gut issues.

    1. Jamie, Mast Cell 360

      Magnesium lotions and liquid magnesiums can be a great option for those who are super sensitive or may have gut issues! Since we are not familiar with your individual case, we cannot say what product or amount may be right for you. Please make sure to discuss adding any new supplements with your practitioner!

    Hi, what about Magnesium Aspartate? Metagenics has this form.

      Hi Catlin,

      Magnesium Aspartate is a highly available form of magnesium, but aspartate (aspartic acid) is often made through fermentation of legumes. It will depend on individual tolerance levels.

        Thanks for this info. I’m having trouble with bowel movements and usually take magnesium citrate but right now I’m in a histamine flare. Usually warm lemon water works also but that is citrus. Any other forms I can take that help with constipation? My bowels are stubborn!

          Hi Michele, as the article above states, Magnesium Oxide is often used for stubborn constipation! Hope this helps!

    Hi, Magnesium glycinate is actually really bad for histamine. It’s on the SIGHI list as a 2 (Incompatible, significant symptoms at usual in-take).

      Hi Roberta, the article does state that the glycine in magnesium glycinate can end up converting to more glutamate which can be a problem in those with high glutamate, but I do not seeing magnesium glycinate on the SIGHI list in regards to histamine. We recommend magnesium glycine because it is well absorbed. The information in this blog is for informational and educational purposes only. It is not meant to treat, diagnose, or prescribe.
