Hello, This is expanded information I received from the Mayo for my FLOT and FOLFOX chemotherapy.
I hope this helps. In research it seams for supplements; every positive study has a negative one. I personally feel that Bromeline and Ellagic acid works well. Some studies indicate; Iron and b-12 has some increase of poorer out comes and cancer reoccurrence. The following is a reply from my Mayo pharmacist;

Yes: Vitamin D3, ferrous sulfate, lutein, ellagic acid, bromelains bulk powder, B12-methyltetrahydrofolate-B6, cyanocobalamin, vitamin B-12, multivitamin with iron pediatric, lactobacillus acidophilus (probiotic)

No: co-enzyme Q-10, astaxanthin, milk thistle, quercetin, N-acetyl L-Cysteine, resveratrol, berberine chloride, alpha lipoic acid
Good luck! RickK
