Are You Actually Getting Enough B12? Most People Think They Are… But They’re Not.

You might think B12 deficiency isn’t something to worry about. If you’re eating a “balanced” diet, whether that includes plants or animal products.. you should be fine, right? Wrong.

The truth is, B12 deficiency is sneaky. It creeps up on you slowly, sometimes taking years to show real symptoms. But once it does, it can hit like a truck. And by then? The damage might already be irreversible.

Where Does B12 Actually Come From?

Vitamin B12 isn’t made by plants or animals, it’s produced by bacteria found in soil and water. In the past, humans and animals naturally got enough B12 from their environment.

But today, modern food production and safety measures (like washing produce and purifying water) have eliminated many natural B12 sources. That’s not a bad thing, these changes have protected us from bacterial infections, parasites, and diseases. But the downside? We’ve lost access to naturally occurring B12 along the way.

Meanwhile, farm animals are no longer grazing on B12-rich soil or drinking untreated water. So, they’re given B12 supplements. Which raises the question:
👉 If animals are just taking B12 supplements, why not cut out the middleman and take it ourselves?

Who’s at Risk for B12 Deficiency?

🔹 Vegans & Vegetarians: Since plant foods don’t naturally contain B12, you’re 100% at risk if you’re not supplementing or eating fortified foods. Even if you feel fine now, B12 deficiency creeps up silently. By the time symptoms show up, the damage may already be done.

🔹 Meat-eaters: You’re not immune either. Yes, animal products contain B12, but your body still needs to absorb it properly. Certain conditions can interfere with absorption, including:
Gastritis & H. pylori infections, Celiac disease & Crohn’s disease, Type 2 diabetes (Metformin users), Acid reflux (PPI & antacid users), Aging (50+ years) and more.

Bottom line? Whether you eat meat or not, B12 deficiency is a real risk.

What Happens If You Don’t Get Enough B12?

B12 isn’t just another vitamin. It’s essential for your nerves, brain, energy, and survival. If you’re low, your body won’t warn you right away. But when it finally does, the symptoms can be brutal:

🚨 Debilitating fatigue – The kind that makes getting out of bed feel like climbing a mountain
🚨 Brain fog & memory problems – Forgetting words, struggling to focus, feeling “off” all the time
🚨 Nerve damage – Tingling, numbness, unexplained nerve pain, or even loss of coordination
🚨 Shortness of breath & dizziness – Feeling like you’re gasping for air, even while sitting
🚨 Heart palpitations – Your heart racing or skipping beats for no clear reason
🚨 Mood swings, depression & anxiety – B12 plays a major role in mood regulation
🚨 Heat intolerance & sudden hot flashes – A lesser-known but a serious symptom
🚨 Pernicious anemia & neurological damage – If left untreated, B12 deficiency can lead to permanent nerve damage, mobility issues, and even an increased risk of Alzheimer’s & heart disease.

This isn’t something to ignore. B12 deficiency doesn’t fix itself and once neurological damage sets in, it might be too late to reverse. How many of these symptoms do you already feel?

Now, let’s talk about how to protect yourself:

A Vitamin B12 deficiency occurs when your blood levels drop below 200 pg/mL (picograms per millilitre) or 0.2 mcg/mL though symptoms can begin even before reaching this level. Ideally, healthy B12 levels should be above 400 pg/mL or 0.4 mcg/mL to avoid deficiency symptoms.

The Recommended Dietary Allowances (RDAs) for Vitamin B12 vary based on age, gender, and life stage. Here’s a quick guide to help you understand how much B12 is ideal for your specific group:

• Birth to 6 months: 0.4 mcg (Male & Female)
• 7 – 12 months: 0.5 mcg (Male & Female)
• 1 – 3 years: 0.9 mcg (Male & Female)
• 4 – 8 years: 1.2 mcg (Male & Female)
• 9 – 13 years: 1.8 mcg (Male & Female)
• 14 – 18 years:
  • 2.4 mcg (Male & Female)
  • 2.6 mcg (Pregnancy)
  • 2.8 mcg (Lactation)
• 19 + years:
  • 2.4 mcg (Male & Female)
  • 2.6 mcg (Pregnancy)
  • 2.8 mcg (Lactation)

Taking Control of Your B12 Health

I was honestly shocked when I found out I had low B12 levels, even though I thought I was doing everything right with my plant-based diet. It took me a while to put the pieces together, but once I did, I dove deep into understanding just how crucial B12 is.

What I learned was eye-opening: B12 is tricky to get, even for those of us who are dedicated to a plant-based lifestyle. As someone who’s worked in nutrition for years, I know that B12 absorption isn’t one-size-fits-all. Health conditions, age, and even stress can all affect how well our bodies use it.

While B12 deficiency is serious, I see it as a challenge we can easily overcome. Whether it’s adding in fortified foods or using supplements, there’s a way forward. I’ve seen it work for me and my family. Taking control of your health doesn’t have to be complicated—it just takes the right tools.

Now that you know how much you need, let’s dive into how to get it right:

• B12 in Animal Products:  You might wonder, “Why not just rely on animal products for B12, like many others do?” The truth is, while animal-based foods do provide B12, there’s more to the story. Let’s take a closer look at how animal products provide B12 and why the source of B12 in these foods may not be as straightforward as it seems.
• Health Risks of Animal Products: Regular consumption of red meat and other animal products has been linked to increased risks of heart disease, certain cancers, and digestive issues. These connections are supported by scientific research.
• B12 on a Plant-Based Diet: While plant foods don’t naturally contain B12, getting enough of this crucial vitamin on a plant-based diet is entirely possible. Fortified foods, like breakfast cereals and nutritional yeast, are excellent sources of bioavailable B12. These options are designed to meet your nutritional needs without compromising your plant-based lifestyle.
• Benefits of a Plant-Based Diet: A plant-based diet offers numerous health benefits, including:
  • Lower risks of heart disease, diabetes, and certain cancers
  • Being rich in fiber, antioxidants, and essential nutrients that promote long-term wellness
  • Reducing inflammation in the body
  • Additionally, the environmental impact is significantly lower than relying on animal-based products, making it a win for both your health and the planet.
• Cutting Out the Middleman: When we look at B12 in animal products, it’s worth noting that the animals themselves are often supplemented with B12. This is because they, too, aren’t getting B12 from natural sources anymore.

So, why not skip the middleman? You can go directly for the B12 through supplements or fortified foods. It’s a more sustainable and direct approach, allowing you to maintain a healthy, plant-based lifestyle while ensuring you’re getting all the nutrients you need.

The Smarter, More Sustainable Choice

Here’s the thing: If we’re talking about B12, why not go straight to the source? Animal agriculture isn’t exactly the most efficient or sustainable way to get your B12. It uses up a lot of resources and harms the environment. Instead, you can get your B12 directly from supplements or fortified plant-based foods. It’s easier, smarter, and way more aligned with a healthy, sustainable lifestyle.

So, not only are you taking care of your body, but you’re also making a choice that supports a healthier planet. It’s about choosing what works best for you, while being mindful of the bigger picture. In the end, it’s all about making choices that feel right for you—without the extra steps.
