Vitamin B12 and Signs of Its Deficiency

vitamin b12

Vitamin B12 is water-soluble vitamin. It helps maintain the health of your brain, nerves and is responsible for your red blood cells creation.

The vast benefits of vitamin B12 include:

  • Reducing depression
  • Boosting energy
  • Decrease sugar cravings
  • Lowering cholesterol and blood pressure
  • Reduces neurological and brain degeneration
  • Protects against cancer

Its deficiency usually leads to physical symptoms before it causes brain issues.

These 10 are the most common:

  • Anemia
  • Depression
  • Constipation
  • Asthma
  • Numbness in the legs, hands or feet
  • Balance issues and difficulty walking
  • Yellow skin (jaundice)
  • Fatigue or weakness
  • Low libido and sperm count
  • Inflamed, swollen tongue

Because Vitamin B12 plays role in formatting the red blood cells it deficiency can lead to the production of immature, large cells that are unable to properly carry oxygen.

Best Sources of Vitamin B12

The best natural dietary sources of B12 include:

  • Grass-fed organic meats,
  • Pastured eggs,
  • Wild-caught fish (salmon, sardines, mackerel),
  • Fortified cereals,
  • Fortified soy
  • Swiss cheese
  • Yogurt
  • Milk

Another option is a supplement. Sublingual tablets are recommended. They are absorbed in the mouth by the blood vessels. They are effective even in people with low stomach acid.

Ask your doctor to test you if you suspect you are low on B12. It is a simple blood draw and it can be done together with other routine screenings.

Vitamin B12 can prevent age-related memory loss, as new study shows. Researchers discovered that people with sufficient B12 suffered less brain mass deterioration and memory loss than those who were short on the vitamin. In fact, the best on memory tests were subjects with the highest levels of B12. The study was recently published in JAMA.

Dementia, mental impairment, and depression are often associated with a deficiency of B12. It is more usual than we think that deficiency of this vitamin appears as a cause of cognitive issues. Our ability to absorb it from food lessens as we age which is due to producing less stomach acid.

So, researchers estimate that 10 to 20% of people over 50 are deficient and it’s no wonder.
