Most children do not need supplements - even picky eaters. But some kids with restricted diets, allergies, or medical conditions may benefit from targeted nutrients. The key is knowing what’s useful and what’s just expensive urine.
Do Picky Eaters Need Vitamins?
Parents often worry their child isn’t getting enough nutrients, especially if they eat only a small range of foods. While that concern is understandable, most children who eat some fruit, some grains, and some protein are getting enough of most nutrients.
Supplements are not a substitute for food, but they can help when intake is very limited.

FAQ: Parents Often Ask
Q: Do gummy vitamins work?
