A children’s magnesium gummy that solves a real problem: small children cannot swallow tablets, and they will happily eat these. It is sold for sleep, which is the one thing magnesium is not permitted to claim, at a dose set just above the legal minimum.
What 546 mg means
The title carries two numbers, and the second one is the real one.
The ingredient list is where the questions start. After the magnesium come glucose syrup, glycerin and glucose, with sugar again in seventh place. Three of the first seven ingredients are sugars, and the listing declares no sugar content, no energy value and no nutrition panel of any kind. For a product given to children at bedtime, that is the omission that matters most, and no parent can work around it.
The product description also states there are “no added flavours or colorants”. The ingredient list ends with natural strawberry flavour and purple carrot juice concentrate. Both are unobjectionable choices; the claim that they are not there is not.
60 mg, for ages three to seventeen
Sixty milligrams is 16% of the 375 mg adult reference value used on supplement labels. That figure is worth pausing on, because 15% is the minimum a product needs in order to make any magnesium health claim at all.
The single dose also has to stretch across a very wide age range. UK reference intakes for magnesium rise from about 120 mg at four to six years to roughly 300 mg by late teens. So one gummy is around half of a five-year-old’s daily requirement and a fifth of a sixteen-year-old’s, with no adjustment offered for either.
One three-star reviewer reached the same conclusion without the arithmetic, writing that the magnesium amount is on the lighter side and the effects therefore subtle. Another reviewer gives her twelve-year-old two a day, which is double the stated dose. The pack says one, and does not explain why.
Sleep is not a claim magnesium may make
Amazon lists the product benefit as “Sleep Support”. The bullets promise support for children’s sleep and a bedtime routine. This is the review’s central regulatory point.
Magnesium has a long list of authorised claims in Great Britain: normal nervous system function, normal muscle function, normal psychological function, the reduction of tiredness and fatigue, normal bones and teeth, and others. Sleep is not on that list. The bullet even cites a real authorised claim — reduction of tiredness and fatigue — then pivots to bedtime, which is a different assertion entirely.
Two smaller notes on the same sentence. It attributes the claim to EFSA; since Brexit the applicable authority in Great Britain is the GB register, not EFSA. And the evidence for magnesium improving sleep in children specifically is very thin: the small adult trials that exist used doses several times higher than 60 mg, and were rated low to very low quality.
What the gummy format changes
The format solves something real. A child who cannot or will not swallow a tablet can take this, and the enjoyment figures in Amazon’s breakdown — 48 positive mentions against one — are the strongest of any product reviewed in this series.
It also creates a problem tablets do not have. An Italian reviewer notes that if it were up to her son he would finish the whole tub; a UK reviewer says her four-year-old thinks she is having sweets. That is the intended appeal working slightly too well, and it is why the resealable tub and the instruction to keep it out of reach are doing more work here than on a jar of capsules.
Magnesium citrate is also the laxative form, used clinically for constipation. At 60 mg the risk is modest, but Amazon’s own breakdown records 22 negative mentions of the calming effect out of 70, including nausea and cramps. A citrate salt in a children’s product is a defensible choice, not an obvious one.
What parents report
Verdict
- Works
- Both 546 mg and 60 mg printed in the title
- Solves the real problem of children who cannot swallow tablets
- Enjoyment 48 mentions to 1 — no daily battle
- Pectin rather than gelatin; stevioside and carrot for colour
- Resealable tub, clear 3+ age floor
- 60 mg is well inside any plausible safe limit for a child
- Doesn’t
- Three of the first seven ingredients are sugars
- No sugar, energy or nutrition panel declared at all
- “No added flavours or colorants” contradicts its own list
- Sold for sleep, which magnesium may not claim
- Cites EFSA, which no longer applies in Great Britain
- 16% of the NRV — barely over the legal claim threshold
- One dose from age three to seventeen
- Citrate is the laxative form; 22 negative mentions in 70
- “Suitable for children” is majority-negative
Worth it if a doctor or dietitian has said your child needs magnesium, tablets are genuinely impossible, and you accept a modest dose and some sugar as the price of getting it into them.
Skip it if you are buying it to fix a sleep or behaviour problem that has not been assessed; if you want to know the sugar content before giving it nightly; if your child is prone to constipation or loose stools; if your child is under three; or if a chewable tablet or a powder would work, since both avoid the sugar and the sweet-shop association.
Check with a pharmacist or GP before starting any supplement in a child, and specifically if your child takes other magnesium-containing products, has reduced kidney function, takes antibiotics of the tetracycline or quinolone class, or if the sleep problem is new, worsening or accompanied by other symptoms.
How we score
Every supplement in this section is judged on the same six criteria, weighted as below. We score the product that left the factory — the formula, the dose, the pack — not the way a retailer has written the listing. Marketing wording is worth pointing out, and we do, but it does not move the score.
Each criterion is scored out of 10 against the norm for its category, not against an ideal: 10 is best practice, 8 solid with minor gaps, 6 works but with a real limitation, 4 a serious shortfall, 2 should not be on the shelf. The overall figure is the weighted average, printed to one decimal place, and the paragraph under the table explains where the marks went.
How we review: every supplement is scored on the same six criteria — formulation 25%, dosing against the evidence 25%, real-world record 20%, value 15%, practicality 10%, transparency 5%. The real-world score reflects the product’s customer rating and, just as importantly, how many ratings stand behind it: tens of thousands of buyers tell you something a desk review cannot, while a few hundred tell you very little. We buy nothing from the brands we cover and take no payment for placement. General information, not medical advice, and not a substitute for advice about a child’s health.
