It can also be connected to lessened synthesis of hormones, e.g., norepinephrine and epinephrine [4,five,six,154]. Peripheral neuropathy following vitamin C encompassing numbness of calves and ache might be relevant to the epigenetic impact of vitamin C. It is thought that vitamin C is required for myelin formation by Schwann cells and it is assumed that these signs and symptoms of peripheral neuropathy is often due to not enough demethylating consequences of vitamin C, which could affect the epigenomic way of activation, proliferation, and differentiation of Schwann cells [102].
