Combination supplement trial reports fewer respiratory infections in children with recurrent illness
The abstract evaluates a mixture of vitamins, minerals, herbal extracts and Lactobacillus rhamnosus CRL1505 in children with recurrent infections.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
Children receiving the combination had fewer respiratory infection episodes on average than those given placebo during observation. The authors also report fewer illness and symptom days, and fewer days of fever-medicine or antibiotic use per episode. They describe the product as well tolerated, but the abstract does not identify which ingredients contributed to these differences.
The abstract gives no initial randomized sample size, ingredient amounts or adverse-event counts. It also leaves the variability terms accompanying the infection averages undefined, limiting assessment of uncertainty and safety.
What researchers found
Mean respiratory infection count
Combination supplement versus placebo over 4 months; the authors report a statistically significant difference.
Who the findings concern
Children qualified because they had experienced repeated respiratory infections during the preceding year. That entry requirement defines whom the trial studied and limits what its results establish for children with a different infection history.
What the comparison can establish
The study compared the complete mixture with placebo. It cannot separate the contribution of Lactobacillus rhamnosus CRL1505 from those of the vitamins, minerals or herbal extracts, so its results do not establish effects of individual ingredients.
