Oxidative stress in the RPE, induced by ROS such as hydrogen peroxide, is hypothesized to be an important driving force in the progression of this disease [16]
Also, AC enhanced antioxidant enzyme activity of SOD, HO-1, and catalase, while reducing ROS levels and alleviating oxidative damage-driven fibrosis (Kondeva-Burdina et al

Without NAD+ there is no ATP
Additionally, chronic conditions such as HIV and tuberculosis have been implicated in B12 deficiency due to increased metabolic demand and altered absorption mechanisms ( The diagnosis of vitamin B12 deficiency typically relies on low total B12 levels and elevated concentrations of homocysteine (Hcy), as well as levels of transcobalamin-bound B12 (holoTC) and methylmalonic acid (MMA), which serve as functional indicators of cobalamin insufficiency ( Vitamin B12 requirements fluctuate throughout the life course, influenced by metabolic demand and physiological changes
