Vitamins and minerals are often consumed for better health and immunity, but a new US study is drawing focus to a danger that may get overlooked. The danger is toxicity if vitamins and minerals are ingested in excessive quantity, particularly for children. Researchers found that 1,961 children were hospitalised for vitamin and mineral toxicity over a three-year period, according to findings presented at the Pediatric Hospital Medicine 2026 meeting in Kansas City, Missouri. The researchers used data from the federal Healthcare Cost and Utilization Project Kids’ Inpatient Database, which captures hospital admissions involving children across the US. But the figure may represent only a part of the problem. “Our study probably only scratched the surface,” lead researcher Marina Masciale, MD, MPH, of Baylor College of Medicine, said while presenting the findings. Most Poisoning Cases Were Due To Intentional Ingesting One of the most interesting findings was that the majority of hospital admissions due to vitamin and mineral toxicity was due to intentional ingestion. That makes the issue different from a child accidentally swallowing one or two tablets. Researchers say the findings highlight the need to consider supplements when assessing children who may deliberately ingest potentially harmful substances. The database also captured only supplements for which there was a specific toxicity-related ICD-10 diagnostic code. This means poisonings involving supplements that were not coded in this way may not have been included. As a result, the researchers believe the true number of affected children could be substantially higher.Also read: Is Your Child Suddenly Sluggish, Clumsy?

Vitamins and mineral supplements are essential nutrients, but consuming more is not necessarily better. On the contrary, it may have a harmful effect. The body requires many micronutrients in relatively small quantities. Some can become harmful when taken in excessive amounts, particularly certain fat-soluble vitamins that can accumulate in the body. Minerals can also cause toxicity when consumed in excessive quantities. The symptoms and severity depend on the substance, dose and how quickly treatment is provided. This is why supplements should not be popped like harmless candies simply because they are sold over the counter.Also read: Too Much Cow’s Milk Linked To Severe Iron Deficiency In Toddlers, Including Three Deaths Why Children Are Particularly Vulnerable? Children have smaller bodies and therefore can receive a much larger dose relative to their body weight after swallowing the same number of tablets as an adult. Many supplements also come in colourful, flavoured or chewable forms, making them particularly attractive to younger children. But the new findings highlight another concern: older children and adolescents may deliberately consume large quantities of supplements, meaning prevention cannot rely only on keeping bottles out of reach. Parents and caregivers should therefore store vitamins, minerals and other supplements securely and treat them like medicines rather than everyday food products. What Should Parents If They Suspect An Overdose? If a child may have swallowed a large amount of vitamins or minerals, parents must not wait for symptoms to appear. The exact risk depends on what was taken, how much was consumed and the child’s age and weight. Some toxic effects may not be immediately evident. Medical professionals may need information from the supplement label, including the ingredients and strength, to determine the appropriate treatment course.
