Last year, a young vegan girl who followed my content sent me a message that I can still clearly recall. “Bhaiya, my doctor says I may have a vegan vitamin B12 deficiency because I’m always tired and my hands are tingling,” she said. However, I eat well and cleanly. How did this occur?
To be honest, I wasn’t surprised by her message. Since a growing number of people are embracing plant-based lifestyles in 2025… However, there is still a lack of B12 awareness. Even today, vegan vitamin B12 deficiency is one of the most common issues new vegans face — not because the diet is wrong, but because the information is missing.
So, this blog is not just a guide… it’s personal.
It’s for all vegans who wish to maintain their vitality, health, and self-assurance without unintentionally making the mistakes that thousands do.
Let’s start…
Why B12 Is a Silent Hero (And Why Vegans Should Care)
Vitamin B12 would be one of the primary programming lines for energy if it had a source code. It keeps your brain sharp, supports red blood cells, and helps your nerves function properly. In other words, it ensures that your body doesn’t feel like an outdated smartphone in battery-saving mode.
The twist?
B12 is not naturally produced by plants. B12 is also not “made” by animals. It is produced by bacteria that are present in soil and the digestive tracts of animals. That’s why vegans often deal with vegan vitamin B12 deficiency — simply because their diet doesn’t include those bacterial sources.
The problem becomes bigger when someone proudly tells you,
“Bro, spirulina se B12 mil jayega!”
No… that’s pseudo-B12. The body can’t use it.
This right here is one of the first reasons vegan vitamin B12 deficiency is increasing in 2025.
My Personal Story: How I Discovered the B12 Trap
When I was first starting my plant-based journey a few years ago, I learned about micro-fatigue. You know, the kind of exhaustion where your body feels like it’s running while your mind keeps loading.
I thought it was lack of sleep.
Then I thought maybe stress.
But the real culprit?
You guessed it — vegan vitamin B12 deficiency.
Additionally, my levels were excruciatingly low when I had them checked. This served as a wake-up call for me, reminding me that while eating healthily is important, eating wisely is even more so.
From that day, I promised myself I’d help others avoid the mistakes I made.
So, when I talk about vegan vitamin B12 deficiency, I’m not speaking like a doctor or a textbook. I’m speaking like someone who has lived it.

Why Vegan Vitamin B12 Deficiency Is Rising in 2025
There are four main reasons:
1. Busy Lifestyle, No Fortified Foods
Everyone is rushing. People skip meals, grab quick snacks, and forget that B12-fortified foods exist.
Result? vegan vitamin B12 deficiency becomes common.
2. Thinking “Natural Diet = Everything Complete”
Nature is perfect, but modern food systems are not. Soil is not what it used to be.
This causes vegan vitamin B12 deficiency even in people who eat whole foods.
3. Poor Gut Absorption
Some people simply absorb less B12, vegan or not.
4. Overconfidence in fake B12 sources
Seaweed and spirulina are NOT reliable.
