Vitamin B12 Deficiency in vegetarians: 3 important facts, and how to fix it

An average adult requires 2.4 micrograms of vitamin B12 a day. But the catch is, our body cannot produce B12 on its own, and it can only be fulfilled through external diet sources. B12 is essential for red blood cell formation, DNA synthesis and nerve health. But vitamin B12 deficiency is a real concern among vegetarians. Reports suggest Indians who follow strict vegetarian diets have limited sources of B12, and thus, are more likely to suffer from its deficiency.

Vitamin B12 deficiency can have effects on both mental and physical health. Low levels of B12 can reduce oxygen transport, as it is essential for red blood cell production. Long-term deficiency can even cause irreversible nerve damage. Vegetarians and vegans are particularly vulnerable to this deficiency. Here we mention 3 important facts about vitamin B12 deficiency, and how to fix it.

Vitamin B12 is primarily available in meat, eggs, fish and dairy. Vegetarians who do not consume adequate dairy products often do not get enough B12 from their diet. This deficiency may slowly develop because the liver stores B12 for several years, meaning symptoms may not appear immediately.

B12 deficiency often shows up as weakness, fatigue, mood swings or memory issues, and these symptoms are commonly mistaken for the result of something else. The silent onset is what makes early detection challenging. Many vegetarians remain unaware that their deficiency is turning into something more serious.

Low B12 levels can increase the risk of cardiovascular diseases, as B12 regulates amino acids in the body. Additionally, low vitamin B12 can also lead to nerve damage and numbness, leading to difficulty with coordination.

Vitamin B12 is a common concern in vegetarians, but the good news is, if detected early, this deficiency is entirely manageable.

• Include fortified foods like plant-based milks and nutritional yeast in daily meals.
• Take B12 supplements in the form of tablets or sprays, after a health professional’s advice.
  
• Recognize early signs and seek medical advice for early intervention.
  
• Include regular blood tests to monitor homocysteine and B12 status.

Even though vegetarian sources of vitamin B12 are limited, there are several effective options that can help reduce the deficiency. Dairy products like milk, yogurt, and cheese are good sources. Eggs, especially the yolk, provide B12. Dairy products like milk, yogurt, and cheese are good sources. Fermented food tempeh and plant-based Nori are also some good options for vegetarians.
