I'll respond from what I have done in my long life. I never have gone for any testing for neuropathy reasons....figured it out on my own, WHY, I ended up with this nerve damage I live with....a messed up hip replacement in my body 10 yrs ago.

As for deficiencies, I believe as we age we just are deficient, Our soils are so depleted and that's why they are called supplements, to replace some of what we lose.

I think it's good to get A1C checked and keep on top of that....diabetes is not a fun thing to be challenged with.

There are givens like Vit D, Vit C is also good to take every day, and in today's mess with the VIRUS, we need a strong immune system.

I believe Thryoid is good to be on top of and so many are living with hypoT and not getting support, I was in that world for 10 yrs many yrs ago.

So this is what I have to say, and again today I even know my young adult grandkids are supplementing.

For the neuropathy issue, there is SO MUCH good info in the PN group here.
