A man in Australia lost his ability to walk after consuming 70 times the recommended daily dose of vitamin B6, ABC Radio Melbourne reported.
But 50 milligrams is much higher than the standard dose recommendation in both Australia and the US, which is 1.7 milligrams of vitamin B6 per day for men over 50. In fact, most people should get enough B6 through eating standard foods like chicken, potatoes, or even spaghetti sauce.
The new, high-dose multivitamin wasn't the only B6 in the man's diet: He was also taking a magnesium supplement, which contained B6, and ate breakfast cereals fortified with B6.
Doses of vitamin B6 that exceed 200 milligrams can cause a loss of feeling to the legs due to peripheral neuropathy, or nerve damage. Some patients can regain the ability to walk if they stop taking the supplements, according to Mount Sinai.
