There are some studies that show low Vit D levels can cause PN type of symptoms. For sure low Vit D will cause muscle pain, bone problems, and other problems but it can also affect the nerve system. Not as much as B12 but everything is connected in our bodies and low D is not good.

My levels were atrocious at 12.6 mL. Who knows how long they were at that point? I should have my results next week to see where my levels are at now.

One thing with Vit D is that you can have TOO much of it, supposedly over 100 mL can become toxic. Your body gets the best Vit D source from the sun and one CANNOT become Vit D toxic from the sun as your body regulates that but pill forms can build up in your system.
