Alpha-Lipoic Acid reduces pain without known cause
A supplement with alpha-lipoic acid reduces pain complaints for which doctors have no explanation. A relatively high dose of 800 milligrams per day works just as well as half that.
Apart from their pain complaints, the test subjects were healthy. So they were not diabetic or pre-diabetic. Diabetes can damage nerves, causing neuropathic pain, often in the feet. Some of the subjects had neuropathic pain, but this was not due to diabetes.
Some of the subjects took a placebo every day for 2 months. Another group took 400 milligrams of alpha-lipoic acid daily, another group took 800 milligrams of alpha-lipoic acid daily.
Both doses worked equally well.
"Thus, in the absence of a diagnosis of pain-causing disease, the use of an alpha-lipoic acid food supplement, [...] could be considered as a feasible option both in the context of general practice and in specialist settings where appropriate."
