Production of these reactive oxygen species is known to occur as a result of a few different mechanisms: 1) mitochondrial origin in which free radicals either escape scavenging enzymes or develop due to an error in oxidative processes, 2) inside the capillary endothelium where a hypoxic and reoxygenation process is created during intense exercise as well as during various types of cardiovascular disease, and 3) an oxidative burst from inflammatory cells which are commonly mobilized as a result of the muscle or tissue damage which is well-documented with extended or eccentric-based exercise[1]
B12 shots are recommended for individuals with a potential B12 deficiency, as well as individuals who feel they need additional nutritional supportespecially when oral supplements are not effective
People often take them to manage oxidative stress or improve skin tone
The science behind it is compelling: research shows that NAD+ levels can drop by up to 50 percent between ages 40 and 60 ( Trammell et al., Cell Metabolism, 2016 ), leading to slower cellular repair, mitochondrial fatigue, and visible skin aging
