- Adult products ≠ children's products — dose bands and capsule safety both matter
- Older teens: near-adult intakes; Futuro Labs Magnesium Glycinate with parental judgement + professional nod
The honest starting point: most children don't need a magnesium supplement
This page exists because parents search for it — usually after reading about magnesium and sleep or restless legs — so here is the straight version. NHS guidance is that children should get the nutrients they need from a varied diet, and magnesium is not an exotic nutrient: wholegrain bread and cereals, beans and lentils, peanut butter and (age-appropriate) nuts, leafy greens, potatoes, dairy and even tap water in hard-water areas all contribute. UK reference intakes are age-banded, climbing from tens of milligrams for small children toward roughly adult levels (around 280-300mg) in the mid-to-late teens — which is precisely why adult doses are not children's doses, and why a supplement decision for a child belongs with a GP, pharmacist or paediatric dietitian rather than a basket.
When the question is really about sleep, growing pains or picky eating
The searches behind "magnesium for kids" usually decode to one of three worries. Sleep: routine, screens and consistent hours out-perform any mineral, and persistent childhood sleep problems are a GP conversation. Leg pains at night: common, usually benign "growing pains" — but persistent, one-sided or worsening pain needs a GP, not a supplement. Picky eating: a paediatric dietitian or a children's multivitamin formulated to age bands (vitamin D drops are already NHS-recommended for younger children) beats repurposing adult minerals. In every branch, the professional conversation is free and the answer usually isn't a magnesium capsule.
For the older teens and the parents' own bottle
Where magnesium supplementation legitimately enters the family picture is at the top of the age range and with the adults. Older teenagers approach adult reference intakes, and with parental judgement — ideally a pharmacist or GP nod, especially alongside any medication — an adult-formulated product can be appropriate.

Frequently asked questions
Can children take magnesium supplements?
Usually they shouldn't need to: NHS guidance is that children should be able to get the nutrients they need from a varied diet, and magnesium-rich foods — wholegrains, beans, nuts where age-appropriate, leafy greens, dairy — are everyday items. Magnesium supplements for a child are a GP, pharmacist or paediatric-dietitian conversation first, not a shopping decision, and adult products are not for young children.
How much magnesium do children need?
UK reference intakes rise with age — from tens of milligrams in early childhood to near-adult levels (around 280-300mg) through the teens. The exact figure for your child's age is a conversation to have alongside professional advice; the practical point is that needs are age-banded, adult doses are not children's doses, and food covers most children comfortably.
Is Futuro Labs Magnesium Glycinate suitable for teenagers?
It is formulated and dosed as an adult product — 300mg elemental magnesium per two-capsule serving in size-00 delayed-release capsules. Older teenagers approaching adult reference intakes may be appropriate users with parental judgement and ideally a pharmacist or GP nod; it is not suitable for young children, both on dose and on capsule-swallowing safety. When in doubt, ask first — the product will still be there after the conversation.
