How Vitamin B12 Supports The Immune System

Vitamin B12 and folic acid are both vital for immune function. Both are necessary for producing a sufficient number of red blood cells to carry oxygen around the body. If you have a folate deficiency and/or vitamin B12 deficiency, your immune system may start to falter, and your body will struggle to ward off pathogens. Red blood cells are crucial immune cells which are part of your bodys immune response so its important to ensure theyre able to form and function correctly.

A lack of vitamin B12 in your diet or through supplements can lead to pernicious anaemia. Pernicious anaemia is an autoimmune disorder that causes the immune system to attack stomach cells, thus inhibiting the bodys ability to absorb vitamin B12. Although the cause of this condition is unknown, supplements can help with the symptoms of pernicious anaemia.

As you can see, vitamin B12 is a key vitamin for helping to maintain a healthy immune system and maintaining levels of both vitamin B12 and folic acid will help to prevent conditions such as pernicious anaemia and folate deficiency.

Can Probiotics Help The Immune System

What Can You Do To Boost Your Immune System

The idea of boosting your immunity is enticing, but the ability to do so has proved elusive for several reasons. The immune system is precisely that a system, not a single entity. To function well, it requires balance and harmony. There is still much that researchers don’t know about the intricacies and interconnectedness of the immune response. For now, there are no scientifically proven direct links between lifestyle and enhanced immune function.

But that doesn’t mean the effects of lifestyle on the immune system aren’t intriguing and shouldn’t be studied. Researchers are exploring the effects of diet, exercise, age, psychological stress, and other factors on the immune response, both in animals and in humans. In the meantime, general healthy-living strategies make sense since they likely help immune function and they come with other proven health benefits.
