Possible foundational causes of stuttering?

Possible foundational causes of stuttering? Been thinking about this for a minute and as you know, every issue has its foundational roots and I think that stuttering might be linked to a severe lack of certain nutrients in the body, and the more we numb this side of things they worsen. I remember a few years ago I had a blood test and I had a severe deficiency in Magnesium, Zinc, B1, Vitamin D3+K2 and a couple more issues . I ignored it at the time because I was pretty young and we didn’t have the money to pay for treatment. My stutter got worse throughout high school and uni. Fast forward and I went for another test a few months ago and these minerals had tanked even further and I decided that I needed to have a total lifestyle change. Started working out again with the aid of supplements to cover for whatever was deficient and I’ve recently started to feel a steady improvement in overall strength and speech control. From my personal experience, I really think scientists should focus on the molecular blueprint behind stuttering… Maybe, just maybe, something would be found.
