The BMJ was unable to find any evidence that this product had been clinically tested, much less proved effective for this indication.
“These combination supplements, unless you’re deficient in something, they really don’t do anything,” said Christopher Gibbons, head of the neuropathy clinic at the Joslin Diabetes Center in Boston.
