Magnesium is also called the master mineral. It is needed for many processes in the body. It strengthens bones and ensures that your nerves can function properly. If you suffer from fatigue, muscle cramps or lack energy, you may lack magnesium. Modern agricultural practices have depleted magnesium levels in the soil, reducing its availability in our food. Consequently, a significant portion of the population may not get enough magnesium from their diet alone, with estimates suggesting that 50% of people might be deficient​. [*], [*]
So, which foods still contain meaningful amounts of magnesium? These are:Â
Pumpkin Seeds – 100g = 534mg
Sesame Seeds – 100g = 351mg
Brazil Nuts – 100g = 376mg
Dark Chocolate – 100g = 327mg
Almonds – 100g = 268mg
Black Beans – 100g = 160mg
Mackerel – 100g = 97mg
Dark Leafy Greens – 100g = 79mg
White Beans – 100g = 53mg
Bananas – 100g = 27mg

In adults, the RDA for magnesium in Europe is 350 mg daily for men and 300 mg for women. [*]
High-dose magnesium supplements are more popular than ever. However, according to nutritionist Chris Masterjohn, PhD, they should be used with caution. Chris: “Most people shouldn't be supplementing with high doses of magnesium. [...] I think there's way too many people throwing really high doses of magnesium into their system.” [*]
So, what is the sweet spot? If you haven't done a lab test, you shouldn't take more than 300 mg without knowing your magnesium status. If you have done a magnesium test and your magnesium levels are low, you can temporarily increase your dosage until it is ideal and continue with a maximum of 300 mg per day. [*]Â
If you're not getting the RDA on a consistent basis, meaning eating large amounts of pumpkin seeds, sesame seeds, Brazil nuts and dark chocolate every day, it's smart to supplement.
Secondly, a lot of stress and a high sugar intake lead to a higher magnesium requirement. Either you need to address that first or supplement during a stressful period. [*]
There is no such thing as just one magnesium. There are different forms (more than 17!) of this mineral, each playing a different role in your body. Let's take a closer look at 12 popular forms of magnesium. Because they are not all created equal.Â
Magnesium citrate is one of the most commonly used forms of magnesium in supplements. It is inexpensive and is quite easily absorbed by the body. It has a laxative effect [*], which can be pleasant if you suffer from constipation. In fact, magnesium citrate is used by the hospital to clean out the colon before a colonoscopy. [*]Â
Magnesium oxide is the second form often used in supplements because it is cheap. It also acts as a laxative. However, its bioavailability is very low - less than 5% - so it is better to skip this one. [*], [*]Â
Magnesium malate is absorbed very slowly, with more of a sustained release. Therefore, it does not have a laxative effect. Magnesium malate works on energy metabolism specifically. [*]Â
Magnesium orotate and taurate fall into the same category. Taurate is chelated, whereas orotate is not. Chelated magnesium (or any other mineral) means that it is bound to an amino acid or organic acid to enhance absorption. Magnesium taurate is bound to the amino acid form taurate, so it is already bioavailable to the body. [*], [*]
You can find magnesium orotate in American formulas, but magnesium orotate is not permitted in the European Union.Â
Magnesium glycinate (the official name is bisglycinate) is magnesium bound to the amino acid glycine. It has no laxative effect because it is absorbed through the intestinal wall. It is considered an ideal form and often recommended by specialists. Though it is a very expensive option. [*], [*]Â
Magnesium glycerophosphate is a form not often seen in supplements, which is a pity. It is a combined source of magnesium and phosphorus, with a 12.5% higher elemental magnesium content than other forms.
In a 2019 study testing the bioavailability of magnesium supplements, it was found to be one of the best-absorbed magnesium supplements, even when formulated with the worst absorbable form: magnesium oxide. [*]Â
Magnesium hydroxide is an ocean-derived, natural form of magnesium hydroxide. It is extracted from seawater off the coast of Iceland, which is the cleanest water in that area. In addition to magnesium, the seawater contains important cofactors and trace elements.
A study done in 2018 with magnesium hydroxide showed that it was much more bioavailable than magnesium oxide and similar in bioavailability to magnesium citrate. It also showed that it can provide additional health benefits given its multi-mineral profile. [*]Â
Magnesium L- threonate is primarily a source of threonate. However, it does not contain that much magnesium and, therefore, cannot be counted as a magnesium source. On top of that, it is not allowed in Europe to use Magnesium L-threonate in supplements. [*]Â
By now, you understand that different forms of magnesium act on different pathways in the body, which is why it is so important to use a supplement that contains multiple forms of magnesium.
Assuming you drink coffee in the morning and stop eating around 7 pm, magnesium is best taken on an empty stomach one or two hours before bedtime.Â
NoordCode Mag Six contains six forms of highly bioavailable magnesium, including citrate, malate, taurate, glycinate, glycerophosphate and hydroxide from sea minerals. These are the most absorbable forms of magnesium and are approved by the European Union. It is formulated with B6 to enhance the absorption of magnesium. More importantly, the composition of the formula is transparent. You know exactly how much magnesium each form contains. Finally, the recommended daily intake includes a safe dosage, so you can take it regularly without worrying about taking too much.
