B12 injections play a key role in maintaining energy levels, supporting proper nerve function, and promoting the production of healthy red blood cells
However, in order for your body to absorb vitamin B12, you need sufficient amounts of a protein called intrinsic factor, which is produced by parietal cells of the stomach
While IGF-1 has important physiological functions, elevated levels carry potential concerns including increased cell proliferation that may support tumor growth in individuals with cancer or pre-cancerous conditions, accelerated aging processes through growth pathway activation, potential cardiovascular effects with chronic elevation, and metabolic consequences including effects on glucose and lipid metabolism
There are no reported risks associated with large doses of B12, since the vitamin is water soluble and excess amounts are flushed out of the system
Research has shown they exhibit overlapping but distinct activity profiles particularly in angiogenesis and hair follicle models
