The B-12 may help the tingling, as others have mentioned. However, there are several conditions which can cause tingling in the feet besides low vitamin B-12, including underlying health conditions or other deficiencies. For example, a magnesium deficiency can be a factor in peripheral neuropathy, include numbness and tingling or a pinched nerve.

So before starting any supplement it’s a good idea to check in with your doctor and maybe have some blood tests.
