Vitamin B12

Vitamin B12 is an essential part of our diet, but it's not something we can produce naturally. It's found in animal products like meat, eggs and dairy (as well as some fortified plant-based foods) and we need to get enough of it to keep us healthy. Unfortunately, deficiency of this vital vitamin can cause a range of serious health issues, including fatigue, anemia and even nerve damage!

(Weirdly), many people don't realize how important Vitamin B12 actually is for their bodies. It helps with the production of red blood cells and aids in proper functioning of the nervous system – both key elements for good health. Additionally, if you're pregnant or breast-feeding you'll need more than usual amounts to support your baby's development.

Nevertheless, despite its importance there are still various groups who may be at higher risk for Vitamin B12 deficiency. Elderly people usually absorb less from food than younger individuals; those on vegan or vegetarian diets often miss out too as it's almost exclusively found in animal-based products; while people taking certain medications may also struggle to metabolize it correctly.

Therefore, although it can be difficult to consume enough through diet alone – especially if you're among one of the vulnerable groups mentioned above – there are other ways to ensure that your levels remain optimal: supplements or injections administered by a doctor being two of them! All-in-all, Vitamin B12 is a crucial nutrient that shouldn't be disregarded; getting enough could make all the difference to your overall wellbeing!
