The MHRA issued the warning on the Nutrition Ignition Kids Magnesium Glycinate Gummies after tests found the product contains melatonin, a prescription-only medicine not listed on the label.

The gummies, marketed as 'a simple supplement to support calm, focus, and digestion in children aged four and older,' were tested in two batches. Each gummy was found to contain between 1.5 and 1.7 mg of melatonin. Packaging suggests a daily intake of one to two gummies, so even the lowest dose could deliver more melatonin than is usually prescribed - and without any medical supervision.
Although melatonin is used in the UK as a prescription treatment for certain sleep conditions in children over six, the usual starting dose for children is 1 mg, rising under medical supervision up to a maximum of 5 mg at night.
Melatonin is generally cleared by the body within twelve hours, and lasting harm is not expected. However, taking too much can cause side effects such as drowsiness, headaches, dizziness, and náuseas.
Dr Alison Cave, chief safety officer at the MHRA, emphasised the need for immediate action.
“We advise any parent or caregiver to stop use of this product and safely dispose of it. Anyone who suspects that their child, or a child in their care, is having a side effect from this product is advised to stop taking it and speak to a healthcare professional and report it directly to the MHRA Yellow Card scheme."
Though sold online as a food supplement, nutrition gummies containing melatonin are regulated as a medicine under UK law - which led the MHRA to withdraw all listings from online retailers.
What parents should know and do
If you have these gummies at home you should store them in a tamper-proof container, out of reach of children, and take them to a pharmacy for safe disposal.
Stop giving the gummies immediately. If your child has already taken them, monitor for any of the known side effects.
Seek medical advice if concerned. Talk to your doctor, pharmacist, or another healthcare professional, especially if your child has symptoms.
Report any side effects. Use the MHRA Yellow Card scheme to help keep such products under scrutiny.
Dispose of them correctly. Don’t throw them away in household waste. Store in a secure container and bring them to a pharmacy.

Le preguntamos a un pediatra por sus mejores consejos.
