(2009, N=40) in PNAS showed that vitamins C and E supplementation blocked exercise-induced improvements in insulin sensitivity [13]
In a state of vitamin B 12 deficiency, the cell responds by redirecting folate metabolic pathways to supply increasing amounts of methyltetrahydrofolate
Yesand in many cases, the results are noticeable within a few months
Both approaches achieve similar results
Individual response varies based on factors including metabolic rate, insulin sensitivity, activity level, and previous peptide experience
