The short answer is it depends on the gummy. Some vitamin gummies are best taken with a meal. Other gummy vitamins should be taken on an empty stomach to reap the full benefits. But most important is to establish a routine when your child takes which vitamin gummy. Taking a gummy vitamin every day at the same time will form a healthy habit, something we all would like to create. It will also help your child get the most possible out of the vitamin gummies.
