I was at UTSW too. Here’s a cut and paste of my supplements... I was able to get through the full chemotherapy regime with no reductions in doseage.
... I used Alpha lipoic acid and glutamine from a day or two before infusion to a few days after - prob 5-6 days each cycle. I usually took 15 grams of glutamine powder mixed in water twice a day and 2 - 500 mg pills of ALC twice a day. Plus 100 mg of B6 to protect against Hand Foot Syndrome, which I never got.
I was a bit more concerned about the calcium magnesium combo, as it's been a little controversial. It used to be a standard part of treatment based on a study showing it reduced neuropathy but it's been pretty much discounted as being effective against neuropathy and one study then seemed to show it reduced chemo effectiveness. Then that study was discounted. Perhaps it really was a zero sum game as the general consensus (and my oncologist) has it nowadays but I'd been taking magnesium and calcium anyway so I upped it to the old doses of 1 gram (1000 mg) of each immediately prior to infusion on the day of chemo only.
I do recall that I heard / read any antioxidants were counterproductive to chemo, as they may "protect" the bad cells from intentional damage by the chemotheraputic agents, whose job it is to damage the "bad" (cancer) cells. I did avoid vitamin C in supplementation form.
I don't know whether any of this truly makes a difference, or just helps give us a sense of control during a frightening time. I'll also say I 100% believe there is no 100% one-size-fits-all solution and everyone's causes, treatments and results are going to vary based their individual biology and genetics.
But so far, my outcome has been good and I'll take it. I'm not far enough out from treatment to comment about the overall effectiveness the other ones I took more for their "anti-cancer" (Curcumin, PSK, Celixicob) and "anti-metastatic" (cimetidine, modified citrus pectin) properties but for the above mentioned four I took specifically to address potential neuropathy, whether I was just lucky or not, I can state it 100% worked and I am one of the lucky ones with no lingering symptoms.
