A confirmed diagnosis of refractory coeliac disease is required to participate in the study unfortunately. Apologies you are feeling miserable even though you have remained gluten-free, I hope you are able to receive further understanding as to why from the relevant medical professional. I am hoping to provide copies of the content used in this study following its completion end of this year so will make a note to post on here when the study is complete, a copy of the resources used from the group. 

Do you think it’s a vitamin issue that could make celiac symptoms worse during recovery ? 

Multivitamin products are seldom potent to offset the vitamin and mineral deficiencies that typically result from long term undiagnosed celiac disease. We commonly recommend sublingual B12, a B-complex 5-10k IU of D3, 400 mg daily of magnesium glycinate, and zinc picolinate. The forms of certain vitamins like magnesium and zinc are important since it has a significant impact on absorbability. If you live near a Costco, the Kirkland Signature series and Nature Made lines are good quality choices and economical. And they will indicate on the packaging if they are gluten free.

I’ve been taking a multivitamin however my doctors appointment is not available till next month for any specific vitamin tests 

Are you addressing possible/probable vitamin and mineral deficiencies through some serious supplementation?
