Excellent taste

“This tastes so good that my kids ask for it every night! They are very picky, so I'm glad to be able to easily get all this goodness into them! I make it as a hot drink for myself before bed.  My daughter and son both get leg cramps and my son is diagnosed ADD so sometimes winding down from the day is very challenging for him. This has helped them both to settle in for bedtime and it's a product I can feel good about giving them and myself.”

It has helped me greatly with my metabolism and energy levels. Enjoy!”

Why Natural Calm Magnesium Citrate

Everyone needs magnesium! It’s an essential mineral that’s critical to the health of every organ, muscle, bone, blood vessel, nerve, and each cell of your body. 

Yet most of us don’t get enough. That’s why symptoms of low magnesium are so common, including irritability, insomnia, tension, cramps, pain and more.

Natural Calm makes it easier — and more delicious — to get enough magnesium. 

  • Never chalky, lumpy, or fake-sweet, Natural Calm tastes like a soothing fruit tea, with nothing artificial added and no sugar
  • Fast-acting, Natural Calm is proven to be more absorbable than other leading magnesium supplements, so you feel the calm quickly
  • Trusted since 1982, Natural Calm is a top-selling magnesium supplement not only in Canada, but globally (and everywhere it’s sold, customers rave about the results)

Everything You Need to Know About Getting Started with Your Calm Routine

Ingredients in Natural Calm Magnesium

Natural Calm is made from simple, pure ingredients:

Magnesium from deep in mineral-rich waters of the ocean. Citric acid from beets sourced from Belgium. Organic fruit flavours and the naturally calorie-free herbal sweetener, stevia.

The only ingredients in our watermelon magnesium powder are:

  • Natural Calm’s proprietary magnesium citrate (made from magnesium carbonate + citric acid)

  • Organic natural watermelon flavour

  • Organic stevia

Citric acid combined with magnesium carbonate dissolved in liquid creates magnesium citrate, one of the most absorbable forms of magnesium available. (3x better absorbed than magnesium oxide.)

Natural Calm is verified non-GMO, gluten-free, vegan, and kosher. It’s also soy-free, sugar-free, free from artificial colours, preservatives, and sweeteners

How to Take Natural Calm Magnesium Citrate

Natural Calm is easy to take! And it’s flexible. 

You can add our magnesium drink mix to smoothies, juices, herbal teas… You can drink Natural Calm hot or cold, with or without food. And it’s great in the morning, afternoon, or at night!

You don’t have to worry about “doing it wrong”… Just follow these guidelines:

  1. Natural Calm becomes absorbable faster when dissolved in hot water. If you’re going to drink it right away, first dissolve it in boiling water. Then, you can drink it as a hot tea or cool it down. 

  2. For less fizz, add a small amount of hot water on top of the powder. Measure out the Natural Calm into your cup first and then add a small amount of hot water (about ¼ cup) just to cover and dissolve the magnesium citrate. This reduces the effervescence to a fun, manageable amount of fizz.

  3. Remember that Natural Calm is like lemon. It’s a “citrate”, which means it has a touch of tartness. You can add it to nearly anything as long as you keep in mind that it acts like lemon. (Keep it out of your milk and probably out of your coffee, too!)

That’s it! Now, enjoy feeling less stressed in body and mind with each sip of Natural Calm.

The Natural Calm Fizz is More than Just Fun

It’s chemistry!  When citric acid (from beets) and magnesium carbonate (from the ocean) combine in hot water to form magnesium citrate, the fizz is carbon dioxide. That’s right, it’s CO2 being released from your cup. 

You’ll know the transformation is complete when the fizzing has settled and the Natural Calm is crystal clear, not cloudy.

There’s no harm in drinking Natural Calm before the CO2 fizzes entirely away. You’ll get more out of Natural Calm, though, if you give it a moment to finish transforming into magnesium citrate. 

So, relax and watch the bubbles… then, feel the CALM!

Find the Right Dose of Magnesium Citrate for You

Your magnesium needs are unique. You may need a bit more or less than average based on factors including:

  1. Your diet: The best sources of magnesium are unrefined plant foods, and most people don’t get enough. If your diet includes processed foods, alcohol, caffeine, sugars, and even animal proteins, you may need more magnesium.
  2. Your lifestyle: Stress, exercise, sweat, and some medications can increase your need for magnesium every day. If you take a calcium supplement, you may need more magnesium.
  3. Your size, gender & age: Every cell in your body needs magnesium, and bigger, taller people do need more magnesium. Men tend to need more, but women are more often deficient and need more during pregnancy.

To help with magnesium deficiency, start with a dose of Natural Calm at the lower end of the range for your age and stage and gradually increase.

Signs You’re Getting Enough Magnesium

Once you start taking Natural Calm, the best way to gauge the right dose is by looking at symptoms. If you’re getting enough magnesium you should be:

  • Falling asleep faster & staying asleep longer
  • Waking refreshed & feeling more energized
  • Feeling calmer, less stressed & less anxious
  • Noticing less body tension & tightness
  • Feeling relief from cramping & pain (if you have those)
  • Comfortably regular

Still feeling symptoms of magnesium deficiency? Increase your dose of Natural Calm, but split it into two doses, one in the morning and one at night. 

Magnesium is eliminated from the body daily, and if you take too much magnesium at any one time, you may experience loose stools. 

Smaller, more frequent doses of Natural Calm are the best way to keep your magnesium levels high — and your symptoms of deficiency low.

    Have been a loyal user since I first found about 10 years ago. It’s the only thing that helps my restless leg and give me a great sleep. I even take the single dose packs on vacation so I’m never without. the gummies are pretty good too but I usually do the powder. The new watermelon takes like a jolly rancher- delicious!!

    I’ve been using this magnesium for a few days and I must say I am starting to see the benefits. I’m a terrible sleeper and I’m finding that I’m able to fall asleep easier, and if I do wake up throughout the night, I can fall back to sleep quickly. I love the watermelon flavour! My preference is to have it as tea in the evening.

Frequently Asked Questions

Magnesium Citrate

What is magnesium citrate?

Magnesium citrate is the mineral, magnesium, paired with citric acid. In supplements, magnesium always comes paired with an acid, an amino acid, or another compound.


In Natural Calm, magnesium citrate is created when you dissolve powdered magnesium carbonate (a mineral sourced from deep in the ocean) with citric acid in water. 

Can I try a sample of Natural Calm?

We have a selection of samples available for a low cost in our shop.  

Why should I choose a magnesium drink over a tablet?

Magnesium supplements in liquid form are the best absorbed. Tablets, while convenient, are widely-known to be less effectively absorbed. Your body only uses a fraction of the magnesium in a tablet.

What is magnesium citrate used for?

Magnesium citrate is used as a supplement to increase magnesium levels in the bloodstream. 

Every cell in your body requires magnesium and it’s eliminated daily, which means you need to replace your magnesium stores daily as well. Magnesium citrate is a fast-acting, highly-absorbably magnesium supplement.

Can I get the magnesium I need from food?

It is  difficult to get the magnesium we need from food alone. Health Canada confirms that most Canadians aren’t getting enough magnesium from diet. This is no surprise given that magnesium is only found in significant quantities in seeds, nuts, legumes and leafy greens. Most North Americans don’t eat enough of these foods to meet their requirements. For a listing of magnesium in foods see

What does 'ionic' mean and why does it matter?

Ionic means that the molecules have gained or lost an electron and seek to attach to something to balance out the electron count. Research has shown that ionic minerals are more easily absorbed by the body. That’s because “the amount of magnesium your tissues can use is based on how soluble the magnesium product is and the amount of elemental or ionic magnesium that is released” (Dr. Carolyn Dean, The Magnesium Miracle, p. 243) Natural Calm magnesium citrate powder becomes ionic when prepared as directed, for fast, effective absorption at the cellular level.


Is Natural Calm organic?

Natural Calm magnesium is sourced from deep in the ocean. It is a naturally-derived product, but because it is harvested, not produced, it is never certified organic. The fruit flavours used are 100% organic.

Is there salt in Natural Calm magnesium?

There is no sodium in Natural Calm. Magnesium citrate is called an organic “magnesium salt” in chemistry terms, like sodium chloride (table salt), but the two are very different. “In chemistry, a salt is an ionic compound that can be formed by the neutralization reaction of an acid and a base. Salts are composed of related numbers of cations (positively charged ions) and anions (negative ions) so that the product is electrically neutral (without a net charge).” (Wikipedia)  These component ions can be inorganic, such as chloride, or organic, such as citrate.

What is the source of Natural Calm Magnesium?

Natural Calm magnesium is extracted from ocean water. The citric acid in Natural Calm Magnesium Citrate Powder is sourced from sugar beets. 

Does Natural Calm contain any sugar, calories or carbohydrates?

There is 0.015 g of stevia per teaspoon of flavoured Natural Calm (no sugar); there are no sweeteners or flavours added to the unflavored version.

Flavoured Natural Calm contains 0.7 calories per teaspoon, and 0.3 grams of carbohydrates. Unflavoured Natural Calm contains zero calories and zero carbs.

Does Natural Calm contain corn or any of it's derivitives?

The unflavoured version of our Natural Calm does not contain any corn or derivatives of corn. The flavouring used in the other varieties (Raspberry Lemon, Sweet Lemon, Orange, Watermelon, and Cherry) does have a sub-ingredient that is derived from corn (organic maltodextrin); however, there are no corn proteins in the product and all flavours of Natural Calm have been verified as non-GMO by the Non-GMO Project. 

Why does it say magnesium carbonate in the ingredients listing? I thought Natural Calm was Magnesium Citrate?

The final product when consumed is magnesium citrate. It is created with a proprietary blend of magnesium carbonate and citric acid. Once added to water, a chemical reaction binds the two together and creates ionic magnesium citrate. As per Health Canada regulation we must list the ingredients in their elemental state.

What is the source of the citric acid in Natural Calm?

The citric acid is derived from verified non-GMO sugar beets sourced from Belgium.


How much magnesium do I need?
The recommended magnesium intake for adults is given by Eat Right Ontario as between 310 and 400 mg per day. Other experts recommend a higher intake daily. For example, Dr. Carolyn Dean suggests that adults consume 3 – 4 mg of magnesium per pound of body weight and that pregnant women and children consume 4 – 5 mg of magnesium per pound of body weight.   Daily needs will vary based on lifestyle, health, and stage of life.
How much Natural Calm should I take?

One teaspoon of Natural Calm magnesium citrate delivers 205 milligrams of magnesium: about half of what men need every day, and about 2/3 of a woman’s required daily intake. Age, life stage, body size, gender, lifestyle, diet and health all affect how much magnesium you should take as a supplement. Pay attention to your symptoms of magnesium deficiency. Constipation and poor sleep, in particular, are two major signs that you need more magnesium.


What is the best way to scoop out Natural Calm powder?

Some customers have asked us how to best scoop the powder out of the container. We find that the best method is to tip the container slightly and use a teaspoon. But it’s getting much easier with our new shorter, stockier bottles!

How do I prepare Natural Calm?

For Natural Calm’s magnesium citrate to become ionic and best absorbed, it needs to be fully dissolved in hot, preferably boiled, water. ( It can then be added to cold water or any other beverage if preferred. )

Should I take Natural Calm with or without food?

You may take Natural Calm’s magnesium with or without food depending on your stomach. It is well absorbed with food. Most people like to take Natural Calm on an empty stomach, and the vast majority of consumers prefer to take Natural Calm in the evening, about 30 minutes before bedtime. 

When should I take Natural Calm?

Magnesium is excreted daily, so ideally you should take Natural Calm morning and night. The very best method is to add Natural Calm to a large water bottle and sip slowly from morning until night. During the day, magnesium can help you to feel a steady, calm energy to meet the challenges of work and play. In the evening, magnesium helps activate melatonin, so you can get a deep and restful sleep when you need it.

My new bottle of Natural Calm is only half full. Why?

Natural Calm is sold by weight (grams or ounces), not volume. When the container is initially filled, the powder has a higher volume because of the distribution of air. Natural settling occurs, during which the air rises to the top and the powder becomes denser. 

Can I prepare Natural Calm in advance and drink it later?

Yes. Many customers do prepare Natural Calm in advance, add it to a large bottle or jug of water, and drink it throughout the day. We recommend that you refrigerate any prepared Natural Calm that is unused after one day.

Is it necessary to use hot water, or can I add Natural Calm to cold water?

When you prepare Natural Calm with hot water, the magnesium powder quickly converts to ‘ionic’ magnesium citrate. This is one of the most absorbable forms of magnesium. Many customers add cold water or juice after the fizzing has settled and the hot solution is clear. When the mixture is flat and clear, it is ready to consume.  

Technically, Natural Calm will mix with cold water, but it is more effective when mixed with hot.


How is Natural Calm Kids different from your regular Natural Calm?

Natural Calm Kids is the same award-winning formula as our Natural Calm formulated for adults. The ingredients and concentration of magnesium are the same, however, the Natural Calm Kids bottle includes a chart for dosage by age, on the label. This dosage table makes Natural Calm Kids more convenient for families with children.

Is Natural Calm safe for babies and children
Caution should be taken when considering any supplement for infants or children with a medical condition. Always consult your health care practitioner. From toddlerhood to teenage years, kids can benefit significantly from Natural Calm. Often their diets are low in magnesium, and even children experience symptoms of magnesium deficiency, including constipation, poor sleep, mood disturbances, fatigue, anxiety, and more. Natural Calm Kids Calm is identical to our adult formula but provides dosing for ages 1 – 18 on the label. Kids will love the natural Raspberry-Lemon flavour, parents will love that it contains no sugar, artificial sweeteners, fake flavours or dyes.


Can I take too much magnesium?

If you take too much magnesium, as with vitamin C, the body will use what it needs and eliminate any excess. The excess will go into the colon, causing it to hydrate, where the only effect is stools that are “loose.”  Millions of people around the world use magnesium simply because of the natural, laxative properties. This would be the only side effect, and any “overdose” is safely depleted through the kidneys. In fact, magnesium is excreted daily, requiring continual replenishment. Take caution if you have kidney problems.  Because excess magnesium is detoxified through your kidneys into your colon, a weak kidney may not work well enough to properly excrete the magnesium.  People on kidney dialysis or who have severe kidney disease should consult their physician before taking any magnesium in supplement form. Anyone with IBS or loose stools should divide their Natural Calm magnesium into smaller, more frequent doses throughout the day.

Is there anyone who should not take magnesium?

People who have kidney disease, a low heart rate (i.e. less than 50), Wolff-Parkinson-White (WPW) syndrome, myasthenia gravis or anyone on blood thinners should consult their doctor before taking Natural Calm.

Is Natural Calm safe to take while pregnant or breastfeeding?

Yes, healthy pregnant and breastfeeding women can safely take Natural Calm magnesium. In fact, magnesium needs will increase during gestation and lactation. Enough magnesium during pregnancy may help with DNA formation and is thought to play a role in preventing complications such as pre-eclampsia. Taking Natural Calm during breastfeeding is beneficial for both mother and baby.

Can I take Natural Calm with medication?

A medically-trained professional may advise you to avoid magnesium while taking certain prescription medications, including blood thinners. If you are taking any prescription medication, please defer to medical advice.

Magnesium will interfere with the efficacy of iron supplements and antibiotics. Discontinue magnesium while on a course of antibiotics. If you take both iron and magnesium daily, take these supplements at different times of the day.

Can I take Natural Calm after it's expiration date?

We do not advise consuming or selling the product beyond its expiration date. Magnesium is a mineral and does not degrade, but the natural fruit flavours in the flavoured versions of Natural Calm have the potential to spoil in the long-term.

Does Natural Calm contain allergens?

Natural Calm does not use common allergen ingredients, however, it is prepared in a facility that processes soy, eggs, peanuts, tree nuts, milk, fish, shellfish, and wheat.  The facility is operated by Nutranext, a major US supplement company with a strong commitment to safety and quality. While the equipment is sanitized after processing allergen ingredients, individuals with allergies should be aware that Natural Calm is not currently certified allergy-free.

Are there heavy metals or toxins in Natural Calm?

Natural Calm is subjected to extensive purity and safety testing to pass Health Canada standards for purity. We retain the certificates of analysis proving that Natural Calm is deemed safe and surpasses purity requirements. In the US, the HealthyLiving Foundation independently purchased and tested all Natural Calm ionic magnesium citrate formulas for chemical toxins including inorganic arsenic, cadmium and lead. Natural Calm received the Tested & Approved Seal from Healthy Living Magazine. This seal assures retailers and shoppers that awarded products are free from harmful amounts of chemical toxins including inorganic arsenic, cadmium and lead, meeting the stringent standards of California’s Prop. 65.

Does Natural Calm contain arsenic?

It is important to understand the presence of arsenic in natural products. Natural Calm magnesium comes from deep in the ocean and like any substance from the earth or water, contains trace amounts of inorganic arsenic. Arsenic is an element found in nature and in man-made products, including some pesticides. As a result, we ingest arsenic every day. All water – including treated municipal water – contains arsenic. Soils also contain arsenic and common plant foods are a source. Two tsp of Natural Calm has less than 1 microgram of inorganic arsenic. In comparison, a serving of long grain brown rice from Whole Foods has about 10 x that amount. (See Most Canadians’ “daily intake of inorganic arsenic from food would be 10.5 µg (micrograms). This contrasts with an intake of <7.5 µg (micrograms) of principally the pentavalent inorganic arsenic species in drinking water.” (From From food and water combined, you are likely getting about 20x the amount of arsenic you would ingest from a normal daily dose of Natural Calm (which is 1-2 tsp.)

Side Effects

Is Natural Calm a laxative?

Natural Calm can be used as a gentle, natural laxative. However, the laxative effect is not specific to magnesium citrate and is unrelated to the ionic status of Natural Calm. Dr. Carolyn Dean explains that “…loose stools…(are) a mechanism to release excess magnesium…Even non-laxative picometer magnesium will cause the laxative effect when you reach saturation and take more than you require.” (The Magnesium Miracle, p. 240) Whether you experience a laxative effect from magnesium depends on how much you take in a single dose. Dr. Dean explains, “If you develop loose stools while taking magnesium…it may mean you are taking too much at one time. Never take your daily magnesium all at once; four times a day is best if you’ve been experiencing diarrhea.” (The Magnesium Miracle, p. 247) Some users may welcome the gentle laxative effect. After all, up to 27% of the Canadian population suffer from chronic constipation. This does not include the population with intermittent constipation due to travel, variations in diet, medication, periodic inactivity, etc. Many users find that Natural Calm soothes the gastrointestinal system quickly and effectively. Magnesium works to regulate healthy nerve function, including the nerves of the digestive system. If a recommended dose on the bottle label is causing loose stools or diarrhea, simply cut down the dose or break it up into two or more doses through the day.

I experience a laxative effect with Natural Calm. What should I do?

Too much magnesium taken orally at one time can cause loose stools. Don’t be alarmed! Magnesium is safely excreted by healthy kidneys and loose stools are part of the elimination process.

If you are uncomfortable, simply decrease the amount of Natural Calm magnesium citrate you take at one time. For example, take smaller amounts throughout the day.

Healthy, regular bowel movements are one indicator that you are getting the right amount of magnesium.
