Vitamin B12 plays a vital role in many bodily functions including proper digestion, iron absorption, and formation of red blood cells. Deficiency can be caused by factors like antacids, nitrous oxide, gastric bypass surgery, and certain bacteria. Symptoms of deficiency include vision problems, anxiety, taste changes, yellow skin, memory loss, dizziness, and numbness. Those at higher risk include vegans, diabetics on certain medications, the elderly, and those with autoimmune disorders. Good dietary sources of B12 include meat, dairy, eggs, seafood, and fortified plant-based options.

- 4. CAUSES OF VITAMIN B12 DEFICIENCY • Deficiency in vitamin B12 may be triggered by different factors, out of which the following are most common: • Antacids affect the assimilation of vitamin B12 since the body needs enough stomach acid to absorb it • Nitrous oxide, also known as the laughing gas, destroys vitamin B12 in the body • Drinking more than 4 cups of coffee a day leads to a 15 percent reduction in vitamin B12 levels • Gastric bypass weight loss surgery changes the digestive mechanisms, affecting the absorption of vitamin B12 • The H. pylori bacteria destroys stomach cells that create the “intrinsic factor”, which are needed for absorption of vitamin B12
- 5. SYMPTOMS OF VITAMIN B12 DEFICIENCY • Optic Nerve Damage / Vision Problems • In case you notice any changes in your vision, such as double or blurry vision, test your vitamin B12 levels as deficiency in this vitamin often leads to vision problems. • Anxiety • Since vitamin B12 stimulates the production of dopamine and serotonin, known as the ‘happy’ brain chemicals, anxiety is often a warning sign of low vitamin B12 levels. • Changes in Taste • The bumps on the tongue are the ones responsible for recognizing the taste of the food you eat. In case you notice changes in your taste and often get a ‘blah’ impression of the food, it is very likely that you are deficient in vitamin B12. • Yellow Skin • When the body lacks vitamin B12, it loses its ability to produce strong cells. The degradation of red blood cells causes yellow skin and is a sure sign of vitamin B12 deficiency.
- 6. SYMPTOMS OF VITAMIN B12 DEFICIENCY • Memory Loss • Memory loss is often caused by vitamin B12 deficiency, especially in younger individuals who are young to develop dementia. • Inability to Keep Your Eyes Open • This is result of lack of oxygen in the blood, which is directly caused by the vitamin deficiency itself. • Dizziness • Feeling dizzy is yet another sign of lack of oxygen in the blood. • Numbness • Feeling numb and tingly is a result of nerve damage, which occurs due to vitamin B12 deficiency.
- 7. RISK GROUPS PRONE TO B12 DEFICIENCY • Vegans and vegetarians who don’t eat products of animal origin • Diabetics on Metformin, as this drug affects the absorption of vitamin B12 • People aged 60 and over who do not have enough stomach acid • People diagnosed with autoimmune disorders, such as celiac or Crohn’s disease
