In the case of Vitamin B6 toxicity, the ‘active’ form of Vitamin B6 known as P5P, also known as pyridoxal-5-phosphate . While in the case of Vitamin B12, the active form is known as Methylcobalamin B12 . These forms are able to be processed by the body so that they get into the cells where they can be utilized for body processes.
Ironically, high B6 levels in blood will decrease and return to NORMAL when sufficient amounts of P5P are taken to remedy the deficiency. The solution to Vitamin B6 Toxicity if you have the MTHFR gene is to stop getting the synthetic forms of B Vitamins, and get the proper active forms the body requires, like that present in a P5P supplement , Methylcobalamin B12 , and a MTHFR Safe Multivitamin and Mineral Supplement.
