Specifically, vitamins B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), and B12 (cobalamin) are involved in various metabolic processes that support energy production
This distinction affects how the compound is absorbed, metabolized, and utilized in the body
The resulting increase in intracellular NAD+ availability activates sirtuins particularly SIRT1, which regulates insulin sensitivity, gluconeogenesis, cholesterol synthesis, and fatty acid oxidation, and SIRT3, which governs mitochondrial antioxidant defences and energy metabolism
This off period allows the bodys enzymatic systems specifically NNMT activity to reset, maintaining responsiveness
