Vitamin C megadosage Based on that study, the American Burn Association (ABA) considers high-dose ascorbic acid an option to be considered for adjuvant therapy in addition to the more accepted standard treatments. Atrial fibrillation (AF) is a common cardiac rhythm disturbance and it is associated with oxidative stress. Four meta-analyses have concluded that there is strong evidence that 1-2 g/day of vitamin C before and after cardiac operations can decrease the risk of post-operative AF. However, five randomized studies did not find benefit in the USA, so that the benefit was restricted to less wealthy countries. Exercise-induced bronchoconstriction (EIB) indicates acute narrowing of
Vitamin B6 Vitamin B6 Vitamin B refers to a group of chemically similar compounds which can be interconverted in biological systems. Vitamin B is part of the vitamin B group of essential nutrients. Its active form, pyridoxal 5′-phosphate, serves as a coenzyme in some 100 enzyme reactions in amino acid, glucose, and lipid metabolism. All forms except pyridoxic acid and pyritinol can be interconverted. Absorbed pyridoxamine is converted to PMP by pyridoxal kinase, which is further converted to PLP by pyridoxamine-phosphate transaminase or pyridoxine 5′-phosphate oxidase which also catalyzes the conversion of PNP to PLP. Pyridoxine 5′-phosphate oxidase is dependent on flavin
