MAG365 consists of just two ingredients: magnesium carbonate and citric acid. When mixed with hot or warm water, these ingredients react to form an ionic magnesium citrate solution.

The signature fizz you see during this process is the result of a natural acid–base reaction: the citric acid breaks down the magnesium carbonate, releasing carbon dioxide (CO₂) in the process. As the magnesium ion binds to the citrate, a highly absorbable form of magnesium—known as ionic magnesium citrate—is created right in your glass.

This fresh activation ensures the magnesium is fully dissolved and readily available for absorption. In contrast, many other magnesium citrate powders are pre-reacted and may not fully dissolve in water, often leaving residue at the bottom of the glass.

The difference? MAG365 is designed to be activated in the moment for optimal absorption, giving you a smooth, fully dissolved magnesium drink with no chalky aftertaste or settling.

To activate MAG365, simply mix the powder with water and allow it to fully dissolve before drinking. The temperature of the water will affect how quickly activation occurs:

• Hot water: activates in about 30 seconds
• Warm water: activates in approximately 3 minutes
• Cold water: takes up to 30 minutes to fully activate

You’ll know MAG365 is activated when the fizzing stops and the solution becomes mostly clear. Once fully dissolved, it can be added to a complementary beverage of your choice, such as juice, tea, a smoothie, or fruit-infused water.

Activation is important because it transforms the magnesium carbonate and citric acid into a highly absorbable ionic magnesium citrate. Failure to complete activation before consumption may result in digestive upset.

Once your MAG365 is fully activated (i.e., the fizzing has stopped and the powder has dissolved completely), you can mix it with virtually any beverage of your choice.

Because MAG365 has a natural citrusy flavour, it pairs especially well with complementary drinks. Many customers enjoy adding it to fruit juices (like orange, pineapple, or apple), herbal teas, smoothies, or fruit-infused water for a refreshing and convenient way to get their daily magnesium intake.

This flexibility makes MAG365 an easy addition to your wellness routine—whether you're blending it into a morning smoothie or stirring it into calming tea before bed.

Provided you don’t have any kidney conditions (excess magnesium is excreted by the kidneys so you want to make sure your kidneys are functioning enough to do this job), the most common side effect of MAG365 is loose stools if too much is consumed. This is simply your body’s way of eliminating excess magnesium that it doesn’t need at that moment.

Some customers also report experiencing more vivid dreams, which may be linked to improvements in their sleep cycles as magnesium supports relaxation and nervous system balance.

Given that magnesium is required for hundreds of enzymatic functions in the body, the majority of effects people notice when supplementing with MAG365 are actually positive ones.

Magnesium is essential for the normal functioning of the nervous system and helps support the body’s natural response to stress. It contributes to muscle relaxation and a sense of calm, making it a popular choice for individuals dealing with occasional tension or restlessness.

During times of stress—whether physical or emotional—your body may use more magnesium than usual, potentially increasing your dietary needs.

That’s why MAG365 is often chosen as part of a daily stress-support routine. This fast-absorbing ionic magnesium citrate formula helps maintain optimal magnesium levels, supporting relaxation and nervous system balance.

MAG365 has also been recognized with a reader’s choice award for Best Stress Relief Product, reflecting its popularity and trusted reputation.

The water does not need to be boiling in order to activate MAG365, however, it activates almost immediately in hot water. If you wish to use cold water, it can take up to 30 minutes to activate. You will know it is activated when the liquid is mostly clear. Once the magnesium is activated, you can cool it down or add it to something else if you desire.

You will not develop a dependency on MAG365, and it is safe to take long term, provided you do not have any kidney conditions. However, if you stop supplementing with magnesium without ensuring proper dietary magnesium intake, your symptoms of magnesium deficiency may resurface.

If you’re experiencing loose stools or diarrhea after taking MAG365, here are a few tips to help your body adjust:

• Split your dose throughout the day to support steadier absorption.
• Reduce your dosage until your bowel movements are comfortably loose—not runny.

It’s also important to note that a small percentage of people may be sensitive to magnesium citrate, regardless of the amount or method of consumption. If you’ve tried adjusting your dose and are still experiencing digestive discomfort, you may benefit from switching to a gentler form.

We recommend PrizMAG Pure Magnesium Bisglycinate. This highly absorbable form of magnesium is exceptionally gentle on the digestive system and contains no fillers or laxative additives.

No—MAG365 does not contain any artificial additives. Our Unflavoured MAG365 is completely additive-free.

In our flavoured MAG365 formulas, the only additions are real fruit extracts and a touch of stevia for sweetness—nothing artificial.

We’re committed to clean, transparent formulas.Read more about our product purity standards here.

The length of time you should take MAG365 can vary from person to person, depending on your individual magnesium levels and symptoms.

Some people may benefit from a higher dose initially to help replenish low magnesium stores. Once your levels are restored, a lower maintenance dose may be enough to support ongoing health and prevent deficiency.

Because daily stress, poor diet, and certain lifestyle factors can quickly deplete magnesium, many people find it helpful to take magnesium consistently as part of their long-term wellness routine.

As with any supplement, it’s best to consult with your healthcare provider to determine the right dosage and duration for your individual needs.

All our magnesium supplements are free of corn. Our magnesium is derived from sea water, and the citric acid is derived from non-GMO sugar beets or cassava.

It’s a great question—and one we hear often. While MAG365 contains citric acid, it becomes an alkalizing drink once fully activated with water. This means it typically won’t aggravate acid reflux when prepared properly.

In fact, magnesium is often recommended for those with acid reflux because it may help relax the lower esophageal sphincter and reduce the backflow of stomach acid into the esophagus.

For a deeper dive into the science behind this, check out our article: Is Ionic Magnesium Citrate Acidic?

Great question! MAG365 is only mildly acidic, with a pH of around 4.9—similar to the natural pH of your skin. For comparison, bananas have a pH of about 5, and cucumbers range between 5.1 and 5.6.

By contrast, your stomach is much more acidic, with a pH typically between 1.5 and 3.5. MAG365 is significantly less acidic than the stomach and, once fully activated in water, can actually have an alkalizing effect on the digestive system.

In short: MAG365 does not contribute to acid reflux or heartburn. Its acidity is mild enough that it should not harm your teeth, especially when consumed as directed.

MAG365 is made from magnesium carbonate and citric acid, which react when mixed with water to form ionic magnesium citrate.

When you add hot or warm water to MAG365, the citric acid reacts with the magnesium carbonate, creating a natural “fizz” as carbon dioxide (CO₂) is released. This reaction breaks down the carbonate and allows the magnesium ion to bind with citric acid, forming a fully dissolved, highly absorbable magnesium citrate solution.

So while MAG365 starts as magnesium carbonate, it becomes magnesium citrate once activated. For a deeper look at how this works, check out our article: Understanding Ionic .

Yes, MAG365 is generally considered safe for use during pregnancy. In fact, the body’s need for magnesium increases during this time, as magnesium plays a critical role in supporting muscle function, nerve health, and energy production.

Research suggests that magnesium may help ease muscle cramps, leg discomfort, and physical tension commonly experienced during pregnancy. It also contributes to the prevention of complications such as preeclampsia and toxaemia when used as part of a balanced prenatal care plan.

However, it’s essential to consult your healthcare provider before starting any new supplement during pregnancy to ensure it aligns with your individual needs and medical history.

It’s true—most people find magnesium helps them relax and sleep better. But for a small portion of the population, magnesium can have the opposite effect, resulting in a noticeable boost in energy—especially when taken in the evening.

That doesn’t mean you don’t need magnesium. In fact, the body uses magnesium to create ATP, the energy molecule every cell relies on. At the same time, magnesium is crucial for relaxing muscles and calming the nervous system. Your response just indicates that you're more sensitive to magnesium’s energizing properties.

If magnesium gives you a second wind at night, we recommend simply taking your magnesium in the morning. You’ll still get the calming and sleep-supporting benefits later in the day—just without the nighttime energy spike.

Prefer something for bedtime? Try PrizMAG. It pairs magnesium with glycine, an amino acid known for its calming effect on the brain and body. This combination helps increase GABA activity, promoting relaxation and nervous system balance—ideal for winding down at night.

Many people find success using both: MAG365 in the morning for calm, focused energy, and PrizMAG in the evening to help transition into restful sleep.

The recommended dose on the label is a general guideline established by regulatory authorities. However, individual magnesium needs can vary significantly based on factors such as diet, activity level, and stress—since magnesium is depleted during times of stress.

If you're considering increasing your dose, it's best to do so gradually. You can increase by ½ teaspoon per day and monitor how your body responds. A good indicator that you've reached your optimal intake is when your bowels are comfortably loose—but not runny.

For best results, we recommend spreading your dosage throughout the day rather than taking it all at once. Many people also find it helpful to reserve a portion of their dose for bedtime, as magnesium supports relaxation and sleep quality.

As with any supplement, it’s important to consult your healthcare provider before making changes to your dosage—especially if you have any underlying health conditions or are taking medications.

Not at all! In fact, vivid dreams are often a sign that your sleep quality is improving. Magnesium supports deeper, more restorative sleep by helping your body reach and maintain REM (rapid eye movement) sleep cycles.

REM sleep is when most dreaming occurs, and it also plays a vital role in memory consolidation, learning, and emotional processing. So while the dreams may feel more intense or memorable, they’re actually a good indication that your sleep is becoming more complete and restorative.

We understand the concern. MAG365 contains citric acid as a key ingredient that reacts with magnesium carbonate to create highly absorbable ionic magnesium citrate.

While it’s true that certain types of microorganisms (such as Aspergillus niger) are used during the production of citric acid, the final ingredient does not contain mould. Citric acid is produced using a safe and well-established process called submerged fermentation, where non-GMO carbohydrates—such as sugar beets in our case—are used as the fermentation base.

After fermentation, the entire solution is filtered and purified to remove all microbial material, leaving behind only pure citric acid. This method is widely accepted in the food and supplement industries and is considered safe for consumption.

Citric acid is commonly found in countless everyday products, including supplements, foods, and medications. In MAG365, it plays a functional role in helping convert magnesium into its highly bioavailable ionic form.

Great question! While a volume measurement like “1 teaspoon” is always the same size, the weight of what fills that teaspoon depends on the substance—because different ingredients have different bulk densities.

For example, a teaspoon of sugar weighs more than a teaspoon of styrofoam, and a teaspoon of MAG365 weighs around 2 grams because of its specific texture and density.

We lab test our products regularly to ensure our dosing instructions are accurate and consistent. Just a heads up—if you’re using MAG365 BF or MAG365 BF+ Calcium, the weight of a teaspoon will be different again, because those formulas include additional vitamins and minerals that all have a different bulk density.
