<<Disclaimer: Verify this information before applying it to your situation.>> My son has had celiac disease since a small child. Now he is a teenager and subject to growth spurts. I'm wondering if he needs any vitamin supplements (perhaps B12 or B6?) because of the restrictions of a gluten free diet. These past few months he seems more lethargic and devoid of energy than the usual teenage boy. Has anyone researched or been advised to take vitamin/mineral supplements by a physician? Thanking you all in advance. Gerry Powell in Ontario [log in to unmask]
