My 9 yr old daughter takes the following daily:
Forvia - a multivitamin for crohn's specifically
omegas - Coromega and an oil capsule
calcium gummy bears
Vitamin D3 - 2000 IU
6-strain probiotic from custom probiotics
Not sure which if any of these is doing anything fantastic, but they are all good for her so I'm assuming they can't hurt. I can say she seems to feel better when taking the Align and when drinking Ensure on a regular basis. The vit D3 seems to be working...no colds or flus in my house this season so far at all...and lots of kids at school have been getting sick, but not her. Oh, and we do keep the omegas in the fridge, easier to tolerate.
