Unfortunately, the answer is no. A recent study in Sweden found a trend toward a reduction in food allergies and seasonal allergies among children 4 years of age and younger who regularly took multivitamins. However, the study failed to show a direct link between the two. It’s a thought-provoking idea, but more studies are needed to prove that multivitamins actually do lower the risk of allergies.
The truth is that many patients often experience multiple ailments -- such as seasonal allergies, asthma and eczema -- and all of these conditions have a strong genetic component. So there really isn’t anything you can do to lower your child’s risk of developing them. But you can help reduce allergy flare-ups by incorporating environmental control measures, such as limiting outside activities when pollen counts are at their highest and avoiding other known triggers and allergens.
