For instance, vitamin b1 is nerve energizer, vitamin b6 helps in nerve signal transmission, while as vitamin b12 work as nerve generator
Foods high in B12 include fish, meat, poultry, eggs, dairy produce, and foods that are fortified with B12 (like some breakfast cereals.) If you follow a restrictive diet or have a condition that impacts absorption, you could be at risk for a B12 deficiency
This contrasts sharply with full-length human growth hormone, which can impair glucose tolerance and insulin sensitivity, potentially precipitating or worsening diabetes
The body's capacity to absorb B12 from food is naturally limited by intrinsic factor, a protein produced in the stomach that binds to B12 and facilitates its absorption in the small intestine
