Magnesium is listed here as a food supplement as a food supplement in the United Kingdom, which is a different category from a licensed medicine. It has not been assessed by the MHRA and is not intended to treat or prevent any disease.
Food supplements are not assessed for effectiveness the way licensed medicines are, so a conversation with a pharmacist or doctor is worthwhile before starting one. What is on the label reflects the manufacturer's own formulation, not a regulator-tested batch, so batch-to-batch consistency is not something any authority certifies here.
