Why Natural Calm Sleep

Getting enough sleep is one of the most important things you can do for your health. 

Not only does your brain need quality sleep in order to “clean” and balance itself, but it’s also during slumber that the heart and blood vessels repair, the immune system strengthens and hormones are balanced.

This nighttime natural sleep aid features a blend of natural sleep-promoting ingredients and tastes like a delicious fruit tea, with organic wildberry flavour and stevia.

Before bedtime, just add water (preferably hot), let it fizz, drink—and then . . . zzzzzzzzzzz.

Natural Calm Sleep makes it easier — and more delicious — to get to sleep naturally. 

  • Never chalky, lumpy, or fake-sweet, Natural Calm Sleep tastes like a soothing fruit tea, with nothing artificial added and no sugar
  • Fast-acting, Natural Calm Sleep 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 (with tens of thousands of 5-star reviews)

Everything You Need to Know About Getting Started with Calm Sleep

Ingredients in Natural Calm Sleep

Each 4 gram* (2 tsp) serving contains:

Natural Calm magnesium citrate (150 mg): Natural Calm’s ionic formula is one of the most absorbable forms available. Known as the anti-stress mineral, it works fast to quiet a racing mind, relax muscles and help normalize the heart rate.

GABA (100 mg): GABA, or gamma-aminobutyric acid is a non-protein amino acid that calms the nervous system, promoting relaxation and downgrading anxiety. GABA naturally occurs in the brain, and the form used in Calmful Sleep is synthetic.

Suntheanine® (50 mg): A patented premium form of L-theanine, Suntheanine® is a calm-enhancing amino acid. It promotes relaxation and reduces nervous tension by stimulating alpha wave activity in the brain.

Magnesium glycinate (70 mg): A form of chelated magnesium, it combines magnesium with the amino acid glycine. Like Natural Calm magnesium citrate, magnesium glycinate promotes relaxation.

Melatonin (5 mg): Melatonin is a natural hormone that helps ease the body into restful sleep and increase total sleep time. While melatonin is spontaneously secreted by the brain, some people produce too little, whether because of jet lag, exposure to light or age-related deficiency.

*Note that many users of Calmful Sleep get results at just 1/2 or 1 tsp. Try a smaller dose to start and increase as needed to the maximum dose of 2 tsp.

How to Take Natural Calm Sleep

Natural Calm Sleep is easy to take! Just follow these simple guidelines:

  1. Natural Calm starts with hot water. Hot water helps make Calm Sleep more absorbable. You can drink it as a hot tea or cool it down, whichever you prefer. But remember to start with hot water! 
  2. For less fizz, don’t overdo the hot water. Spoon Natural Calm Sleep into your cup and cover it with just enough hot water to dissolve the powder (about ¼ cup). Stir and watch it fizz!. Then add more water if desired.

  3. Take Calm Sleep before bedtime. Natural Calm Sleep is a natural sleep aid. Take it about half an hour before going to bed. You will likely sleep for a full night after taking Calm Sleep.

That’s it! Now, enjoy a deeper sleep with help from this 100% natural sleep aid.

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 Natural Calm Sleep for You

Your sleep needs are unique. Factors that determine the perfect Calm Sleep dose for you include::

  1. Your diet & lifestyle: You may need more Calm Sleep if you have a low magnesium diet. Other factors that can influence the right dose for you include your stress levels, whether your sleep-wake cycle is disturbed, your caffeine intake — and more.


  1. Your “normal” sleep quality: If you have only occasional difficulty falling asleep, you may find you only need a little Calm Sleep to notice a big improvement. Regular sleep disturbances? You may find you need more Calm Sleep,


  1. Your size, gender & age: Your body mass affects how much of a supplement you need. Bigger, taller adults may need more Calm Sleep to get the same results. If you’re on the smaller side you should start with a smaller dose.


We recommend that all users start with ½ tsp or 1 tsp of Natural Calm Sleep before bed. Increase as needed to the maximum dose of 2 tsp (4 grams) for adults.

This product is not intended to treat, cure or prevent any disease.

This natural sleep aid is formulated for adults only. Keep out of reach of children. May cause drowsiness. Do not operate a vehicle or heavy machinery following consumption. Consult a physician if you are pregnant, nursing, have a medical condition or are currently on medication.

Using Calm Sleep with Other Natural Calm Magnesium Products

Calm Sleep is a natural sleep aid for times when you need extra sleep support. It does contain magnesium and can help you to meet your daily magnesium requirements.

If you only take a small dose of Calm Sleep every night or on occasion, you may also need a daily magnesium supplement.

Try taking our award-winning Natural Calm magnesium citrate supplement about 12 hours apart from taking Calm Sleep, so you can maintain healthy magnesium levels all day. You’ll know you’re getting enough magnesium when you are:

  • 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

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.

Note that this product is not intended to treat, prevent or cure any diseases or conditions.

Reviews for Natural Calm Sleep

Frequently Asked Questions

Calm Sleep

If I take Calm Sleep, do I still need a magnesium supplement?

Calm Sleep is a blend of natural sleep-promoting ingredients, one of which is magnesium. 2 tsp of Calm Sleep contains about 220 mg of magnesium, which is an adequate supplement for many adults. Calm Sleep alone may not be an adequate supply of magnesium if:

  1. You are taking less than 2 tsp of Calm Sleep per day, as many people do. For example, often only 1/2 tsp of Calm Sleep is needed to resolve insomnia, and that dose contains only about 55 mg of magnesium.
  2. Your magnesium supplement needs are higher than what you get from Calm Sleep, even at the full 2 tsp dose. Some people just need more than 220 mg of magnesium daily.

You may recognize that you need more magnesium if you have tension, pain, anxiety or constipation – even if you’re sleeping well with Calm Sleep. The natural sleep ingredients in Calm Sleep can address insomnia at a low dose, but you still need to get enough magnesium. Keep your magnesium levels high by continuing to take Natural Calm magnesium while you use Calm Sleep, if needed. Either mix Natural Calm magnesium with Calm Sleep at night or take Calm Sleep alone at night and take Natural Calm magnesium in the morning or afternoon.

How long will a bottle of Calm Sleep last?

Most individual users will find the bottle lasts between 1 and 4 months. If you take a full dose of 2 tsp nightly, the bottle of Calm Sleep will last at least 20 days. Most users will find their sleep is dramatically improved at a much smaller dose. 1/2 tsp per night is a good starting point and may never need to be increased, in which case the bottle would last almost 4 months.

Why isn't the bottle full?

As with other powdered products, settling occurs. When the powder is bottled, it is extremely fluffy from the production process. There is so much air mixed in with the Calm Sleep, that the powder must be pressed down manually in order to seal the cap. Over time, the product settles and the volume decreases, but the total amount of product (113 grams) does not change.

Can I take Calm Sleep every day, indefinitely?

Calm Sleep contains the hormone, melatonin, and Health Canada recommends melatonin for temporary relief from sleep disturbances. Some research indicates that longer-term use may be appropriate. Consult a medical professional to ascertain the risks and benefits specific to your health.

How much Calm Sleep should I take?

The dose on the label, approved by Health Canada, is 2 tsp or 4 grams. However, users have experienced the sleep-enhancing benefits at lower doses. We recommend starting with 1/2 to 1 tsp and increasing to 2 tsp as required.

What is the Mixed Berry flavour made from?

Calm Sleep is flavoured with organic blueberries, blackberries, and raspberries, sweetened with organic stevia. The slight tart flavour comes from citric acid, which is an essential part of the Natural Calm magnesium formula. Flavoured Natural Calm contains 0.7 calories per teaspoon, and 0.3 grams of carbohydrates.

Are there side effects associated with Calm Sleep?
Calm Sleep is formulated to reduce the time it takes to fall asleep, and help you stay asleep longer. Drowsiness is a natural side-effect. Some users experience vivid dreams after taking Calm Sleep. This is due to L-theanine’s effect on alertness and should subside after a few nights’ use.
Why is there melatonin in Calm Sleep?
Calm Sleep is specifically formulated for nighttime sleep support. Melatonin is a natural hormone that helps ease the body into restful sleep and increase total sleep time. While melatonin is spontaneously secreted by the brain, some people produce too little, whether because of jet lag, exposure to light or age-related deficiency.
  1. You are taking less than 2 tsp of Calm Sleep per day, as many people do. For example, often only 1/2 tsp of Calm Sleep is needed to resolve insomnia, and that dose contains only about 55 mg of magnesium.
  2. Your magnesium supplement needs are higher than what you get from Calm Sleep, even at the full 2 tsp dose. Some people just need more than 220 mg of magnesium daily.

You may recognize that you need more magnesium if you have tension, pain, anxiety or constipation – even if you’re sleeping well with Calmful Sleep. The natural sleep ingredients in Calm Sleep can address insomnia at a low dose, but you still need to get enough magnesium. Keep your magnesium levels high by continuing to take Natural Calm magnesium while you use Calm Sleep, if needed. Either mix Natural Calm magnesium with Calm Sleep at night or take Calm Sleep alone at night and take Natural Calm magnesium in the morning or afternoon.

Why is there L-theanine in Calm Sleep?

Calm Sleep is a relaxing nighttime drink formulated for extra sleep support. We’ve added Suntheanine®, the patented premium form of the amino acid, L-theanine, to promote relaxation and reduce nervous tension.

Why is there GABA in Calm Sleep?

GABA, or Gamma-aminobutyric acid, is a non-protein amino acid that calms the nervous system, promoting relaxation and downgrading anxiety. GABA may also improve mood, help with PMS symptoms, treat ADHD, reduce blood pressure, and play a role in synthesizing melatonin, the sleep hormone. GABA naturally occurs in the brain, and we’ve used a synthetic form in Calm Sleep.

What are the precautions associated with Calm Sleep

Do not take Calm Sleep before operating a vehicle or heavy machinery. Calm Sleep includes melatonin, which may cause drowsiness. Melatonin supplements can interact with various medications, including blood-thinning medications (anticoagulants), medications that suppress the immune system (immunosuppressants), diabetes medications and birth control pills. Consult a physician if you are currently taking medications and wish to use Calm Sleep. Mild gastrointestinal symptoms and rare allergic reactions have been known to occur, in which case, discontinue use.

Why are there two types of magnesium in Calm Sleep?

Research suggests that magnesium citrate is the more absorbable magnesium, but magnesium glycinate is less likely to cause a laxative effect in users with sensitive bowels. By combining the two in Calm Sleep, our formula delivers a high dose of magnesium that can be taken by anyone. The amino acid, glycine, may in itself have a calming effect on the brain, another good reason for including this form of magnesium in Calm Sleep. Magnesium glycinate is a chelate formed from magnesium with the amino acid, glycine. Glycine may have a calming effect on the brain, another good reason for including magnesium glycinate in CalmSleep.

Is there anyone who should not take Calm Sleep?

Natural Calm’s Calm Sleep product with melatonin, GABA and L-theanine is formulated for adults only. Parents, consult a health care professional before considering this product for your children. Melatonin is a natural hormone and caution should be taken when administering hormones to children. Consult a physician if you’re pregnant, nursing, have a medical condition or are currently on medication.

At what time of the day shoud I take Calm Sleep?

Calm Sleep is specifically formulated to be taken in the evening, 30 – 60 minutes before bed. Use during the day may cause drowsiness.

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.
