Vitamin B12 Deficiency 

There are certain factors that can cause someone to be more likely to have a vitamin B12 deficiency even if their daily intake is high. Age makes it more difficult to absorb B12 so if you don’t make sure you are consuming enough animal products and supplements that contain vitamin B12 you might suffer from a deficiency. If you have anemia, auto immune disorders, atrophic gastritis or any conditions that affect your small intestine it will
 be more difficult to absorb B12 putting you at risk for a vitamin B12 deficiency as well.
Vegans and vegetarians are at high risk for a vitamin B12 deficiency because the foods that contain B12 are animal products such as milk, eggs, fish, meat, and poultry.  It is extremely important for vegans and vegetarians (who don’t eat enough eggs or dairy products) to use vitamin B12 supplements. B12 supplements often come in the form of a pill or a spray and help consumers meet their minimum daily B12 intake! vitamin b12 supplementation

  2. Anemia: According to Harvard Health anemia can be caused by a lack of vitamin B12 intake or an inability to absorb B12 from food. Symptoms of anemia can include fatigue, shortness of breath, migraines and an increased heart and breathing rate.
  3. Pale or jaundiced skin: By pale skin we don’t mean that you spent a few too little days in the sun this summer. If your skin is much paler than normal, has a yellowy tint, or if you have a yellowish tinge in your eyes then you might have jaundice. According to Pub Med this can be associated with a lack of vitamin B12 because a deficiency causes problems with your body’s red blood cell production.
  4. Stress, anxiety and depression: Mental health issues are a huge concern and can be devastating to the person suffering from stress, anxiety and depression and their families. Studies show a correlation between B12 levels and a patient’s ability to halt mental health symptoms. In particular, patients with high levels of vitamin B12 were able to overcome stress and anxiety faster than those with low levels or deficiencies.
  5. Weight gain or difficulty losing weight: Gaining weight is frustrating for men and women of all ages. Consuming efficient levels of vitamin B12 can increase your metabolism helping you lose the extra pounds. A deficiency in Vitamin B12 places stress on the body making it harder to be active and even perform day-to-day tasks. This can reduce your ability to lose weight.
