B6 level high because I was taking a B Complex for 4 months with 100 mg B6 which is 5, 887% of the RDA of B6. Your doctor can order a B6 bloodtest or you can use Walk-in Labs to check your serum level. Serum levels can be in the normal range within 3 weeks of quitting supplements. This is because the excess B6 accompanied by a dehydrating event was stored in muscles and nerves causing small fiber polyneuropathy. It can take a year to two years to eliminate the toxicity from muscles and nerves.
