B12
A study published in the journal Acta Neurologica Taiwanica found that vitamin B-12 supplements minimized common DPN symptoms, including tingling, pain, numbness and burning. Although some effectiveness in lessening pain was shown, more human studies are necessary.
Foods high in B12: Liver, mackerel, skim milk, beef
B1
A lack of B vitamins can lead to other health conditions, such as anemia. A lack of B1 (thiamine) could lead to diabetic complications like DPN. Researchers from the University of Essex in England found a connection between a lack of B1 vitamins and the development of hyperglycemia.
Foods high in B1: Trout, lean pork, sunflower seeds, macadamia nuts, green peas
B6
B6 has been shown in studies to also help with reducing DPN symptoms. In one study, Type 2 diabetics who took a B6 supplement for four months reported less neuropathic pain at the end of the study.
