5 Signs of Vitamin B12 Deficiency That May Deceive You

Vitamin B12 is a crucial nutrient that supports various bodily functions, including maintaining a healthy nervous system, DNA synthesis, and energy production. However, its deficiency can often go unnoticed due to the subtle and deceptive nature of its symptoms.

Here are signs of Vitamin B12 deficiency that you should be aware of:

  1. Fatigue and Weakness: A lack of B12 can lead to fatigue and muscle weakness.
  2. Heart Palpitations and Shortness of Breath: Anaemia caused by B12 deficiency can result in these symptoms.
  3. Nerve Problems: Tingling and numbness in hands and feet may indicate nerve damage.
  4. Mood Changes: B12 deficiency can lead to mood swings, depression, and memory problems.
  5. Digestive Issues: Nausea, diarrhoea, and loss of appetite can also indicate low B12 levels.

 Causes of Vitamin B12 Deficiency

Vitamin B12 deficiency can arise from various factors, including inadequate dietary intake, mal-absorption issues, certain medications, and medical conditions like pernicious anaemia. Vegetarians and vegans are particularly at risk due to the absence of B12 in plant-based foods.

How to Get Tested for B12 Deficiency

If you suspect a B12 deficiency, it’s important to consult with a healthcare provider. Blood tests measuring serum B12 levels, methylmalonic acid, and homocysteine levels are commonly used to diagnose deficiency.


Depending on the severity, treatment for B12 deficiency typically involves dietary changes, oral supplements, or injections. A highly recommended supplement is NOW Foods B-12 2000mcg, which provides vitamin B-12 in three forms, including the two readily available and activated co-enzyme forms, methylcobalamin and dibencozide. This product ensures the maintenance of a healthy nervous system and the production of energy from fats and proteins, making it an essential addition for those at risk of deficiency.

Five Food Sources of Vitamin B12

  1. Beef Liver: One of the richest sources of B12.
  2. Clams: Another excellent source of B12.
  3. Fortified Cereals: A great option for vegetarians and vegans.
  4. Nutritional Yeast: Often fortified with B12, making it a vegan-friendly option.
  5. Plant-Based Milk Alternatives: Many are fortified with B12.

By understanding the signs, causes, and treatments and incorporating B12-rich foods and supplements like NOW Foods B-12 2000mcg into your diet, you can ensure adequate B12 levels and support your body’s critical functions.
