In this ideal guide to supplementation, we cover everything you need to know about B12: the benefits, symptoms of deficiency, where to get it, supplements, how much of it you need, and how to choose supplements that work for you.

🧠 What Is Vitamin B12?

Vitamin B12 is a water-soluble vitamin that plays essential roles in the body, such as:

• DNA synthesis

• Energy production

• Nerve function

• Red blood cell formation

• Brain health

It’s particularly important for those following a plant-based diet, older adults or anyone experiencing fatigue or trouble concentrating.

🔍 Why B12 Is So Important

Without sufficient B12, healthy red blood cells, which carry energy-giving oxygen to all body cells, cannot be formed, and neurological health cannot be maintained. If you are living with a deficiency in the long run, it can result in:

• Anemia

• Nerve damage

• Mood disorders

• Cognitive decline

• Fatigue and weakness

Health Benefits of B12:

• Boosts Energy Naturally

• Lifts Mood and Combats Depression

• Supports Brain and Memory Function

• Healthy Skin, Hair and Nails Aid

• Assists In The Prevention Of Birth Defects In Pregnant Women

• Heart health – lowers homocysteine

⚠️ Signs You Might Have a B12 Deficiency

And a B12 diet deficiency can surprise even if you’re eating well. Here are common symptoms to watch for:

• Constant fatigue

• Brain fog or memory issues

• Numbness or tingling in the hands and feet

• Mood swings or irritability

• Pale or yellowish skin

• Shortness of breath

• Dizziness or lightheadedness

If you are getting one or more of these symptoms, I would recommend getting a B12 blood test.

🥬 Whole Food Sources of B12

B12 is in animal products. If you are an omnivore, you’re likely getting some from your food. Top sources include:

• Liver (beef and chicken)

• Sardines and tuna

• Salmon

• Eggs

• Milk and dairy products

• Soymilk and fortified cereals (vegetarians/vegans)

🌱 Vegans and Vegetarians may lack B12

Plant-based diets are healthy but may not provide enough B12. Plants do not make B12, so vegans have to depend on:

• Fortified foods

• Nutritional yeast

• B12 supplements

If you are a vegan, supplementing is nonnegotiable to prevent deficiency.

💊 Types of B12 Supplements

There is more than one type of B12 supplement. The best one for you is the one that suits your body’s needs.

1. Cyanocobalamin

   • Most common, synthetic form

   • Affordable and effective

   • Suitable for general use

2. Methylcobalamin

   • Natural, bioactive form

   • More suitable for neurological and cognitive support

   • Wonderful for those who malabsorb

3. Hydroxocobalamin

   • Frequently used in B12 shots

   • Longer-lasting effects

   • Prescribed by physicians for severe insufficiency

4. Adenosylcobalamin

   • Supports energy production in the mitochondria

   • Commonly used along with methylcobalamin

💉 B12 Injections vs. Oral Supplements

B12 Injections:

• Infused into the bloodstream

• Perfect for those with malabsorption, a serious deficiency, or some type of condition

• Administered by a healthcare provider or self-injected

Oral Products (Pills/Gummies/Spray):

• Ideal for general maintenance

• Cheap and cheerful

• Best on an empty stomach or with B-complex

✅ How Much B12 Do You Need?

Recommended Dietary Intake (RDI) may vary between age, gender and health status:

Group	RDI
Adults	2.4 mcg
Pregnant Women	2.6 mcg
Breastfeeding Women	2.8 mcg
Older Adults (50+)	100–500 mcg from supplements due to low absorption

As ever, talk to your doctor before trying supplements, especially if you have medical conditions or take medications.

🧪 How to Test Your B12 Levels

A simple blood test can determine your B12 status. The target range for serum B12 is ideally:

• Greater than 300 pg/mL for better health

• Under 200 pg/mL is considered insufficient

• 200–300 pg/mL, may indicate a marginal deficiency — further testing necessary

💡 Tips for Taking B12

To maximize B12 absorption:

• Take in the morning — helps your energy level early in the day

• Do not take with vitamin C at the same time — can interfere with absorption

• Take with a B-complex for added benefits

• Sublingual (under the tongue) choices may enhance absorption in some cases

🧬 Who Needs Extra B12?

Some groups are at increased risk of deficiency and could benefit from supplementation:

• Vegans and vegetarians

• People over age 50

• Those with digestive issues (Crohn’s, celiac, IBS)

• Participants on metformin or acid-reducing medicines

• Those who have had gastric bypass surgery

• Women who are pregnant and breastfeeding

📦 How To Choose The Best B12 Supplement

When purchasing B12 supplements, you should also look for:

• Third-party tested for purity

• Clean label – no unnecessary fillers or artificial ingredients

• Easy dosing — tablets, drops or sprays
