What is the link between sleep and magnesium?
Is magnesium really necessary? It’s a question many parents ask themselves. We’re happy to help clarify its role.
After a day full of stimulation, children often have difficulty calming down. Think of taking a long time to fall asleep, waking up restlessly at night, tossing and turning late into the night... But what does magnesium have to do with this?
Magnesium?
Magnesium is a mineral that helps the nervous system relax. It’s not just a “nice-to-have,” because it plays a role in more than 300 functions in the body. From growth and energy to a good night’s sleep and a calm nervous system. It supports relaxation, sleep, muscle development, and helps ensure a good night’s rest.
Common signs of magnesium deficiency include muscle cramps, fatigue, irritability, and sleep problems. A standard blood test isn’t always a reliable indicator, because magnesium is primarily found inside cells. A large proportion of children don’t get enough magnesium. This often starts as early as during pregnancy. Additionally, our diet contains less magnesium than it used to, partly due to intensive farming. So even if you eat a healthy diet, getting enough magnesium isn’t always a given.
Magnesium is one of the few minerals that your body can absorb through the skin. Your skin cells recognize it, and it is absorbed step by step: first through the skin, then by the cells and surrounding tissues, and finally into the bloodstream. This skips the gastrointestinal tract, reducing the risk of stomach upset and ensuring faster results. A magnesium spray is safe, with no risk of overdose. The skin absorbs only what is needed, so your child doesn’t take in too much. And magnesium is absorbed even more comfortably by young skin thanks to glycerin. This glycerin reduces skin irritation and moisturizes the skin.

Gentlee’s Magnesium Spray contains this ingredient. This means it’s not a “mini-version of an adult spray,” but truly a magnesium spray developed for children. Moreover, Gentlee’s Magnesium Spray contains one of the highest concentrations of magnesium for children, sourced from an ultra-pure source: less spray, more effect.
A magnesium spray is best applied to the feet. The soles of the feet contain many sweat glands, allowing the magnesium to be absorbed more quickly. The skin there is also thicker and less sensitive, ensuring the spray is absorbed effectively without stinging or irritation. Furthermore, unlike hands and arms, the feet remain still, giving the magnesium time to absorb.
Does my child need (extra) magnesium?
Common signs of magnesium deficiency include muscle cramps, fatigue, irritability, and sleep problems. Magnesium is an all-around mineral hero: it helps with muscle relaxation, sleep regulation, and healthy growth.
The Gentlee Magnesium spray can provide relief from growing pains, help improve sleep, and reduce stress or tension. The great thing is that transdermal magnesium is absorbed directly through the skin, without burdening the digestive system. That means less risk of stomach upset and faster results. Ideal for children who benefit from relaxation, better sleep, or muscle relaxation. The spray helps combat stress and anxiety. Magnesium is known for its calming effect and can help children who have trouble relaxing.
If a simple spray on the skin can help your child sleep more peacefully and feel better, then it might be worth a try, right?
A (new) bedtime ritual?
A gentle bedtime ritual that brings the day to a peaceful close—who wouldn’t want that? Because a good bedtime ritual is the foundation of better nights.
Gentlee is formulated around magnesium, a mineral that helps calm the nervous system for a better night’s sleep, and is specially tailored to children’s sensitive skin. 100% natural, gentle, and formulated in Belgium. We’re making bedtime a safe, gentle, and predictable moment for children again. With transdermal magnesium as the foundation of small rituals that help the body wind down and welcome the night.

With the new Gentlee Bedtime Bath Flakes, your little one can also relax even more in the bath. A bath is naturally a time for calm. In warm water, the flakes dissolve completely, allowing the magnesium to come into contact with the entire skin, not just the feet. The warm water helps the skin absorb the magnesium smoothly, while your child simply plays. Where the spray concludes the ritual, the bath begins it.
