Vitamin B12 Deficiency occurs when the body does not receive or absorb enough Vitamin B12, an essential nutrient required for nerve function, red blood cell formation, and energy production. Since the vitamin is naturally found in animal-based foods, vegetarians may face challenges maintaining adequate levels.
Why Pure Vegetarians Are More Vulnerable
Vitamin B12 is present mainly in dairy, eggs, fish, and meat. A purely plant-based diet offers very limited natural sources, leaving strict vegetarians dependent on fortified foods or supplements. Over time, low intake can quietly lead to deficiency without early warning signs.
Why B12 Matters for Everyday Health
- Supports healthy nerve function
- Helps produce red blood cells
- Aids metabolism and energy levels
- Supports mood stability and brain health
- Plays a role in DNA synthesis
Why the Deficiency Develops Quietly
Vitamin B12 is stored in the liver and depleted slowly. This means symptoms may take months or even years to appear. Many people confuse early signs—such as tiredness or hair thinning—with routine stress, allowing the deficiency to worsen silently.
