In general, functional mushrooms are considered safe even for young children however we do not recommend use on a regular basis. Our mushroom products should be ok for for children 6-7 years old and up. Before 6 years old, the child's own immunity is still building itself so if there is no special need to modulate it with these safe but potent functional mushrooms, we recommend waiting until the child is at least 6 years old.
It is best to start with lower doses (1/3 - 1/2 a packet per day). Build the dose up from there if it seems to work well for the child and if it feels necessary however we do recommend the child only consume the mushrooms 3-4 times a week. Don't forget to check the ingredient list for any allergies!
