Frequently asked questions

Magnesium is an ion (Mg2+) that needs to be bound to another molecule to be stabilized and to pass from the intestine into the bloodstream. This molecule is called a transporter, and there are several types. Check out our dedicated infographic to learn more.

It's true that with a name like that, marine magnesium sounds appealing. The reality is less glamorous: it's made up of more than 80% magnesium oxide, a transporter known for its very low absorption (4%). Just marketing to drive sales? To learn more, check out our article on marine magnesium.

Since excess magnesium is easily eliminated by the kidneys, an overload is rare. The few observed cases have been associated with severe kidney failure. People with this type of condition should consult their doctor.

Taurine is sometimes paired with magnesium and potassium supplements because it may improve their penetration into cells. It's also sometimes associated with these two micronutrients for its effects on performance and endurance. However, the doses used in this case are large (1-6g per day), and the magnesium sources we've chosen are already well absorbed enough to do without a cofactor like taurine. With 4 capsules per day for 400 mg of elemental magnesium, you have everything you need to top up your levels!

A magnesium cycle generally lasts 2 to 3 months, the time needed to rebuild your magnesium stock (around 25 grams). Athletes, pregnant women, and older adults may, however, supplement continuously due to their higher needs.

From our point of view, the debate between natural and synthetic is a mistake. The real question is whether an ingredient is bio-identical or not, meaning whether it has a form identical to what's found in our food. While magnesium does occur naturally in sea salt in the form of oxide, we know this transporter isn't identical to conventional dietary forms. The result? This form is poorly absorbed and often causes digestive issues. We therefore prefer bio-identical forms of magnesium, meaning those whose transporter is recognized as a nutrient by the body: > malic acid found in apples, > bisglycinate, made up of 2 glycine molecules, an amino acid naturally present in the body. > or even natural microcapsules, made of corn starch and sunflower lecithin.

Athletes have above-average magnesium consumption and therefore need to replenish their stock regularly. This mineral is involved in ATP production (muscle energy), cramp reduction, and protein synthesis. While a balanced diet provides a decent daily intake, we can only recommend supplementation to ensure the NRVs are met.

In principle, no. We've selected 3 types that are particularly well tolerated and don't cause digestive issues. Salts like marine magnesium or oxide cause digestive problems due to their osmotic activity: they attract water and disrupt digestion. Malate and glycerophosphate salts, as well as liposomal magnesium, are not osmotic at all and therefore don't cause any digestive discomfort in principle.

No, our capsules don't contain any chemical or synthetic dyes. What gives them their beautiful blue color is a natural phyto-pigment extracted from spirulina algae: the well-known phycocyanin.

Some magnesium bisglycinate products show up to 18 or even 20% elemental magnesium content. On closer inspection, though, these turn out to be so-called "buffered" forms of magnesium bisglycinate, meaning that magnesium oxide is added to artificially increase the elemental magnesium content. These forms are therefore no more effective than non-buffered or 100% chelated forms, which have a content of 11%. As you can see, the 20% forms are more of a marketing gimmick than anything else.

Seaweed is by far the best dietary source of magnesium, but it's not widely consumed in Western diets. Since magnesium is a component of chlorophyll, it's also found in all leafy green vegetables and fresh herbs. Whole grains and oilseeds are also good sources.

Signs of magnesium deficiency can include fatigue, muscle spasms (notably eyelid twitching), high blood pressure, or cardiac arrhythmia. These symptoms aren't exclusive, however, and can stem from other deficiencies or various conditions.

If we had to choose, liposomal magnesium offers both excellent content and very good absorption. But supplementing it with other salts such as bisglycinate and malate is useful to maximize absorption pathways.

You can either spread your magnesium intake throughout the day with one capsule at each meal, or take your daily dose in the evening at dinner time to benefit from its relaxing and sleep-supporting effects.
