Hi,  There are two brands I've trusted : ez melts and Nature's Bound. I personally don't take a multi vitamin, only get the ones my Dr. tells me I'm low in based on my annual test results, but I'm pretty sure both have one or something close for you. Quality ingredients grown  (mostly) and both have non GMO ingredients, plus are processed here in the US.

Thought I had a good multi-vitamin (365 for women) but this morning I began to feel a bit queasy at breakfast (all carefully selected gluten-free items), about 15 minute after dropping my vitamin. I’ve taken these for about a month and have overall felt more pep in my step, but never thought to look at the ingredients list until the nausea came on. You probably already guessed: yep. So I was just going to Google best gluten-free multi for women plus iron and go past the sponsored results when it occurred to me, I would be better to trust the forum than Google AI. Anyone have a recommendation that they would share?

Thank you both for your insights. I think I’ll have to repeat testing in a few months and have a longer period of gluten consumption. 

The "IgA 47-310 normal range" = is the total IGA test I mentioned in an earlier test. It goes by a number of names. He is not IGA deficient.

Doctors don't usually test the levels of all the B vitamins.  B12 is frequently the only one checked.   Ask for an Erythrocyte transketolase test to check Thiamine Vitamin B 1  levels.  The eight B vitamins all work together, so they should all be supplemented.  Additional thiamine in the form Benfotiamine can be taken.
