You need to take a more systemic approach.
I know that T1 diabetes folks often have low Vit D levels and low thiamine levels; that's a clue.

I would get labs for Vit D then implement sunning, sperti lamp, and Vit D + K tincture (https://healthnatura.com/vitamin-d3-in-mct-oil-5000-i-u-1-ounce/, https://healthnatura.com/true-k2-spectrum-mk4-mk7-10mg-200mcg-1-ounce/).
After that, I'd probably work with a team (like prism.miami) to implement thiamine therapy, ala thiamineprotocols.com.
Both Vit D and B1 (thiamine) are relatively safe, so the risk/return is good, but T1 diabetes is delicate and you want to move slowly and intentionally, especially if she's on pharma now.
