Electrolyes are useful at any time…to keep a balance
We at times don’t drink enuf water, because it’s not always easy to go to where we need to be then? But Gatorade for me is useful the day prior to infusions as it helps w/hydration. Be careful about it tho if you are diabetic -just read the ingredients.
Dawn is right about Potassium, D and Magnesium? Just keep an eagle eye on B-6 tho, as too much can make neuropathies worse. The first 3 are good in helping nerve re-generation.
I hope this helps a bit.
