Buyer's Guide: Everything You Need to Know About Magnesium
Magnesium has a role in countless chemical reactions that take place in your body. It's a component of bone structure and plays an important role in the formation of energy (ATP), modulating muscular, neuronal and hormonal functions. Magnesium can have activating or relaxing functions, depending on where in the body it's found.
What exactly is magnesium?
Despite its importance, magnesium never received much attention in clinical work. Nonetheless, more recently, a handful of studies have shown a correlation between low magnesium diets and several diseases (obesity, diabetes, hypertension or polycystic ovary syndrome), indicating its importance and encouraging further investigation of its benefits by health professionals.
Which bodily functions does magnesium have a role in?
|Musculoskeletal||Formation of tooth and bone structure|
|Cardiovascular||Relaxation of muscle fibers, formation of muscle fibres|
|Nervous||Arterial dilation, transportation of cholesterol, relaxation of the heart muscle|
|Digestive||DNA stabilization, raised sensitivity to insulin, ATP synthesis (energy)|
Which foods are rich in magnesium?
Magnesium is also commonly found in:
- Fruits (bananas, oranges, lemons and grapefruit)
- Dried fruits and vegetables
- Soy products like tofu and miso
- Whole grain cereals (rice, whole oats)
- Linseed and pumpkin seed
- Dark chocolate
Although magnesium is found in a wide variety of foods, studies have indicated that fruits and vegetables grown in impoverished soils offer a much lower concentration of the mineral.
What are the signs of a magnesium deficiency?
People who suffer from gastrointestinal disorders, those who have had bad burns and anyone undergoing significant psychological or physical stress may also lose more magnesium than normal, and they may be at risk of a magnesium deficiency. The body's ability to absorb magnesium also declines with age.
Pregnant and breastfeeding women, athletes, students preparing for tough exams and those recovering from a medical operation are also likely to need higher levels of magnesium.
Magnesium deficiency can impact the entire body. Here are some of the most common symptoms:
- Lack of energy
- Menstrual issues
- Muscle cramps (particularly in the legs, at bedtime) and muscle weakness
- Frequent muscle injuries, trouble concentrating and trembling
Some studies indicate that deficient magnesium may play a role in the following medical issues: cardiac arrhythmias, obesity, diabetes, kidney stones, increased cholesterol, anxiety and depression.
Why are magnesium supplements recommended?
The following groups are likely to benefit from magnesium supplements:
- Students preparing for tests
- People who suffer from insomnia
- People with frequent muscular or joint pain
- Pregnant and breastfeeding women
- People over age 40
- People facing physical or emotional stress
- People on weight loss diet
- People diagnosed with pre-diabetes
- People with alcoholism
How can magnesium supplements improve my health?
- Improved memory and concentration
- Relief of insomnia and fatigue
- Faster recovery following a workout or from muscle injuries
- Decreased bone and joint pain
- Relief from dysmenorrhoea (menstrual cramps), impotence and low libido
- Boosts insulin sensitivity and cholesterol control, making it easier to control weight and blood glucose
- Improved mood, with higher ability to deal with stress
- Improvement of cardiovascular health
- Wrinkle prevention, better skin and hair appearance
What kinds of magnesium are available and which is best for me?
The table outlines the most common preparations, to help you pick the supplement that best suits your needs:
- Magnesium oxide: This is the most common and cheapest form. Its taste can be unpleasant (try taking it with fruit juice) and it is best consumed in small doses several times each day to ensure proper absorption.
- Magnesium glycinate: This preparation binds magnesium to glycine, which is an amino acid that boosts absorption capacity. The effect is fast and mostly relaxing, so it's recommended to take it in the evening. It is unlikely to result in a laxative effect.
- Magnesium citrate: This is an acid formulation that is used as a laxative. Some studies blame this formulation for interfering with copper metabolism, so people with liver disorders should be cautious.
- Magnesium threonate: This form is among the most modern options. Threonate helps magnesium directly enter the mitochondria (the part of a cell responsible for producing energy), and it is therefore especially useful for dealing with fatigue.
- Magnesium sulfate: This form is not commonly used as a supplement, but instead as a medicine to treat seizures in pregnant women. Don't take this kind without a doctor's prescription.
- Magnesium taurate: This form offers the benefits of magnesium without the laxative effects as its impact on the gastrointestinal system is limited.
- Magnesium chloride: Chloride strengthens magnesium absorption and helps achieve high mineral concentrations with just a small amount of the supplement.
- Magnesium malate: This formulation combines magnesium with malic acid, which is often found in fruits. It offers a high absorption capacity and those who take this supplement report a reduction in joint and muscle pain, as well as increased energy for sports.
- Magnesium carbonate: This cheap supplement has laxative effects and is commonly used for constipation and heartburn.
What is the recommended magnesium dosage?
|Population group||Recommended daily dose|
|Babies 0-6 months||30 mg|
|Babies 7-12 months||75 mg|
|Children 1-3 years||80 mg|
|Children 4-8 years||130 mg|
|Children 9-13 years||240 mg|
|Boys 14-18 years||410 mg|
|Girls 14-18 years||360 mg|
|Adult males||400-420 mg|
|Adult females||310-320 mg|
|Pregnant women||350-360 mg|
|Men over 40||420 mg|
|Women over 40||420 mg|
How much do magnesium supplements cost?
Can I take too much magnesium?
Hypermagnesemia can result in dizziness, heart rate disturbances and muscle weakness. If you experience any of these symptoms, visit the nearest hospital.
We have gathered information on the most important purchasing factors to help you choose the magnesium supplement that best suits your needs:
As you now know, magnesium affects over 300 reactions in the body. Still, the impact of the various preparations are more or less potent depending on the specific part of the body. Magnesium glycinate or taurate are the best options if you're hoping to ward off stress and anxiety.
Magnesium threonate, meanwhile, will help you boost your intellectual capacity, and citrate or magnesium carbonate have laxative effects. If you can tolerate the taste of magnesium oxide multiple times each day, it's also a great option, both balanced and affordable.
Cheaper supplements are often more difficult to absorb, and you'll need to consumer higher doses to achieve the same benefits found in the more expensive supplements. This is a key factor influencing the value for money of the different supplements.
Most magnesium supplements are suitable for gluten-intolerant individuals, vegans, diabetics and those with nut allergies. Always check the labelling, and don't be afraid to ask a doctor or pharmacist if you have any doubts.
Allergic reactions to magnesium chloride do occur, with the following symptoms: nausea, dizziness, general redness of the body and respiratory distress. If any of these symptoms appear, go to the nearest emergency room and stop supplementation immediately.
The laxative effect of magnesium is one of the primary side effects, an issue for many people. In case of diarrhoea, you should limit your intake of magnesium until your body adjusts. You can then gradually increase the dose to the recommended amount.
Those suffering from diabetes, hypertension or heart disease should also discuss potential side effects that can result from mixing magnesium with other medications (especially insulin) with their healthcare provider.
Last but not least, even though studies have indicated that magnesium can help fight depression and anxiety, antidepressant medication should not be replaced by magnesium supplementation.
Method of Ingestion
Magnesium supplements are sold in various forms:
- Powder: Easy to mix, and it lets you easily adjust dosage. It may have a bitter or "earthy" flavour.
- Tablets: These can be divided to adjust dosage, and they can be crushed to mix in with a drink or meal. Magnesium oxide makes tablets taste bad.
- Hard capsules: These are easy to take, except for those who have trouble swallowing pills.
- Softgels: These offer the same benefits, but are often easier to ingest than hard capsules.
Now you're familiar with how important magnesium is for proper bodily functions. Today, society moves at an ever faster pace, and our diets are increasingly lacking in fruits and vegetables. Meanwhile, people want to remain active and competitive at increasingly older ages. Magnesium supplements are designed to give you the extra energy and health you need to enjoy life to the fullest.
We hope that the information we've gathered in this article will help you pick the best supplement for your needs, at a price that you find reasonable.
