Magnesium Gummies vs Liquid for Kids: Which Is Better?
The short answer: gummies are convenient and children like them, but most rely on sugar or sweeteners and can only hold a small amount of magnesium per sweet. A truly unflavoured liquid takes a moment to mix in, but it lets you dose exactly by age, adds no sugar and does not look like sweets on the shelf. For most families who want a daily habit, liquid is the simpler long-term choice.
Side by side
| Gummies | Unflavoured liquid | |
|---|---|---|
| Taste | Sweet, made to be liked | Neutral, disappears into a drink |
| Sugar or sweeteners | Usually yes | None needed |
| Dose by age | Fixed per gummy | Measured in ml, scales with age |
| Magnesium per dose | Often modest | Easy to set at a useful level |
| Risk of over-eating | Higher, they look like sweets | Low |
| Convenience | Very easy | Needs a cup or spoon |
| Storage | Cupboard | Check the label; some go in the fridge once opened |
The case for gummies
Gummies are popular for good reasons. There is nothing to measure, nothing to mix and most children take them happily. If your child refuses anything that is not a sweet, a gummy might be the only way to get a supplement in at all.
The case against gummies
- Sugar. Most gummies are sweetened with sugar or glucose syrup, or with sweeteners such as sorbitol, which can upset some tummies. The NHS advises that children aged 4 to 6 have no more than 19g of free sugars a day, and a sticky sweet every evening, after teeth are brushed, is not ideal for teeth.
- Small doses. Minerals like magnesium take up space and can taste bitter, so a gummy can only hold so much before it becomes too big or too unpleasant. Always check the milligrams of magnesium per gummy, not the headline on the jar.
- They look like sweets. That is the point, and also the problem. Children may ask for more, and a jar left within reach is easy to raid.
- Quality varies. In 2025 the MHRA told parents to stop using one brand of kids' magnesium gummies after finding undeclared melatonin. Read what the MHRA warning means.
The case for liquid
- Precise dosing by age. A toddler and a ten-year-old need different amounts. With a liquid you simply measure a different number of ml.
- No sugar needed. A truly unflavoured liquid does not need anything sweet to mask it.
- It hides well. Stirred into water, milk, juice, a smoothie or yoghurt, most children do not notice it. See our tips for fussy eaters.
- No negotiation. It is part of a drink, not a treat to bargain over at bedtime.
The downsides of liquid
You need a measuring spoon or syringe, it takes a few seconds longer, and some liquids have a noticeable taste if they are flavoured to cover the mineral. Liposomal liquids should also be kept out of hot drinks and, like ours, stored in the fridge once opened.
How to decide
- If your child will drink something every evening, a liquid is the easiest way to build a sugar-free habit.
- If you choose gummies, check the sugar, the milligrams of magnesium per gummy and that the brand tests every batch.
- Whatever the format, choose a gentle form such as magnesium glycinate and follow the dose for your child's age.
We chose a liquid for our own magnesium for kids for exactly these reasons: 2.5ml for ages 1 to 5, 5ml for ages 5 to 14, no sugar, no flavourings, and nothing that looks like a sweet.
