Neuropathy

SupplementAmountWhy
Acetyl-L-Carnitine
500 to 1,000 mg three times daily3 stars[3 stars]
Taking acetyl-L-carnitine can reduce pain in people with diabetic neuropathy, but does not appear to consistently benefit cases of chemotherapy-induced neuropathy.
Magnesium
200 to 600 mg daily3 stars[3 stars]
Supplementing with magnesium may reverse poor magnesium status and improve diabetic peripheral neuropathy, but does not appear to be helpful for preventing or treating chemotherapy-induced neuropathy.
Vitamin B6, Vitamin B12, and Folic Acid
2,000 mcg methylcobalamin (B12); 3,000 mcg methylfolate (B9); and 35 mg pyridoxal 5-phosphate once to twice daily3 stars[3 stars]
B vitamins, and vitamin B12 in particular, may be helpful in treating various types of neuropathies. People with type 2 diabetes taking metformin should be monitored for B12 deficiency.
Vitamin D
7,100 IU daily or 50,000 IU weekly of vitamin D3 for eight to twelve weeks, followed by 2,000 to 4,000 IU daily long term3 stars[3 stars]
Supplementing with vitamin D3 daily or weekly can help reduce symptoms of diabetic neuropathy.
Alpha-Lipoic Acid
600 to 1,200 mg daily2 stars[2 stars]
Alpha-lipoic acid may reduce symptoms of diabetic peripheral neuropathy and may work best in combination with medical treatment for neuropathy. Its possible benefit in chemotherapy-induced neuropathy needs further investigation.
Coenzyme Q10
400 mg daily2 stars[2 stars]
There is little evidence that coenzyme Q10 improves nerve function and eases symptoms of diabetic neuropathy.
Vitamin E
300 to 600 mg (450 to 900 IU) daily2 stars[2 stars]
Vitamin E supplementation may protect against diabetes- and chemotherapy-related neuropathy.
Biotin
Refer to label instructions1 star[1 star]
There is anecdotal evidence that high-dose biotin may reduce pain from diabetic nerve damage.
N-Acetyl Cysteine
1,200 mg daily1 star[1 star]
A small body of evidence suggests N-acetyl cysteine may help prevent neuropathy.
Omega-3 Fatty Acids
1,200 to 1,800 mg daily of omega-3 fatty acids from fish oil1 star[1 star]
Preliminary evidence suggests omega-3 fatty acids from fish oil may help to prevent diabetes- and chemotherapy-related neuropathy.
  • Reliable and relatively consistent scientific data showing a substantial health benefit.
  • Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
  • For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by some in the medical community, and whether studies have found them to be effective for other people.

For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
