Top Vegan B12 Supplements for Energy
The Critical Role of B12 in Vegan Energy Levels
As a vegan, I know firsthand how challenging it can be to maintain optimal energy levels. One nutrient that plays a crucial role in our energy production is vitamin B12.
This essential vitamin is involved in many bodily functions, including the production of red blood cells, DNA synthesis, and the proper functioning of our nervous system.
For those following a plant-based diet, obtaining adequate B12 can be particularly tricky since it’s primarily found in animal products. This is where supplements become invaluable for vegans looking to maintain their energy levels and overall health.
Understanding B12: The Energy Essential
Vitamin B12, also known as cobalamin, is a water-soluble vitamin that’s essential for energy metabolism in every cell of our bodies. It works in tandem with other B vitamins to convert the food we eat into glucose, which provides energy for our cells.
B12 is unique among vitamins because it contains a metal ion, cobalt, which gives it it’s name. This complex structure also means that B12 is the largest and most structurally complicated vitamin.
In the body, B12 exists in several forms:
- Methylcobalamin
- Adenosylcobalamin
- Hydroxocobalamin
- Cyanocobalamin
Of these, methylcobalamin and adenosylcobalamin are the active forms used directly by the body. Cyanocobalamin, while not an active form, is often used in supplements because of it’s stability and lower cost.

The B12 Challenge for Vegans
Historically, humans obtained B12 from soil bacteria on unwashed vegetables and from drinking water from streams or wells. However, our modern, sanitized world makes this virtually impossible.
Most B12 in our food supply comes from animal products, where it’s concentrated after animals consume B12-producing bacteria.
This presents a significant challenge for vegans. Without careful planning and supplementation, vegans are at a higher risk of B12 deficiency.
Vegan B12 Deficiency symptoms include:
- Fatigue and weakness
- Shortness of breath
- Dizziness
- Pale or yellowish skin
- Smooth tongue
- Mood changes
- Memory problems
In severe cases, vegan B12 deficiency can cause irreversible nerve damage. That’s why it’s crucial for vegans to be proactive about their B12 intake.
Top Vegan B12 Supplements for Energy
Now that we understand the importance of B12, let’s explore some of the best vegan-friendly B12 supplements available:
1. Methylcobalamin Sublingual Tablets
Methylcobalamin is the active form of B12, ready for immediate use by your body. Sublingual tablets dissolve under your tongue, bypassing the digestive system for enhanced absorption.
This makes them an excellent choice for people who have digestive issues or absorption concerns.
Some high-quality brands offering methylcobalamin sublingual tablets include:
When using sublingual tablets, allow them to dissolve completely under your tongue as opposed to chewing or swallowing them whole. This ensures most absorption through the mucous membranes in your mouth.
2. B12 Oral Spray
For those who dislike tablets, B12 sprays offer a convenient alternative. These sprays deliver a fine mist of B12 directly into the mouth, where it can be absorbed through the oral mucosa.
Garden of Life’s B12 Organic Spray is a popular choice, delivering a potent dose of methylcobalamin with just a few spritzes. It’s perfect for on-the-go supplementation and is often favored by travelers or those with busy lifestyles.
Other notable B12 sprays include:
When using a B12 spray, aim the nozzle towards the inside of your cheek for optimal absorption. Hold the liquid in your mouth for 30 seconds before swallowing to allow time for absorption.
3. Liquid B12 Drops
Liquid B12 supplements offer precise dosing and easy absorption. They’re often combined with other B vitamins for synergistic effects on energy production.
This form is particularly useful for those who have difficulty swallowing pills or prefer to mix their supplements into beverages.
Some top-rated liquid B12 supplements include:
When using liquid drops, you can take them directly under your tongue or mix them into a small amount of water or juice. If mixing, try to consume the entire drink quickly to ensure you’re getting the full dose.
4. B12-Fortified Nutritional Yeast
While not a supplement in the traditional sense, B12-fortified nutritional yeast is a tasty way to boost your intake. Nutritional yeast is a deactivated yeast that’s rich in B vitamins and has a cheesy, nutty flavor that many vegans love.
Brands like Bragg’s or Bob’s Red Mill offer B12-enriched options that can be sprinkled on everything from popcorn to pasta. However, not all nutritional yeast is fortified with B12, so always check the label.
While nutritional yeast can be a great addition to your B12 intake, it shouldn’t be relied upon as your sole source of B12. The amount of B12 can vary between brands and batches, and it may not provide enough to meet your daily needs on it’s own.
5. Vegan B12 Gummies
For those who prefer a more enjoyable supplementation experience, B12 gummies are a great option. These chewy supplements often come in fruity flavors and can make taking your daily B12 feel like a treat.
Some popular vegan B12 gummies include:
While gummies can be a fun way to take your B12, be mindful of their sugar content. Some brands may contain added sugars or artificial sweeteners, so always check the ingredient list if you’re watching your sugar intake.
For those who prefer a one-stop solution, consider multivitamins that include B12 and other key nutrients. Our article on the Best Multivitamins for Vegans. highlights excellent options.
Maximizing B12 Absorption
To get the most out of your B12 supplement, consider these tips:
- Take your B12 on an empty stomach or with a light meal for optimal absorption. B12 absorption can be inhibited by heavy meals, especially those high in fat.
- If using sublingual tablets or sprays, allow them to fully dissolve or absorb in your mouth before swallowing. This gives the B12 more time to be absorbed through the mucous membranes.
- Pair your B12 supplement with foods rich in folate, like leafy greens or legumes. These nutrients work synergistically in the body.
- Be consistent with your supplementation. Taking B12 regularly is more effective than taking large doses sporadically.
- If you’re over 50, have had fat loss surgery, or take certain medications (like metformin or proton pump inhibitors), you may need higher doses of B12. Consult with a healthcare provider to determine the right dose for you.
Beyond Supplements: Boosting B12 Naturally
While supplements are crucial for most vegans, you can also boost your B12 intake through fortified foods. Many vegan products are now fortified with B12, including:
- Plant-based milk choices (soy milk, almond milk, etc.)
- Certain breakfast cereals
- Some meat substitutes and veggie burgers
- Fortified energy bars
- Some brands of tofu
Remember, relying solely on fortified foods can be risky, as the B12 content may vary between products and batches. A dedicated supplement is often the most reliable way to ensure adequate intake.
The B12 Balancing Act: Finding Your Optimal Dose
The recommended daily intake of B12 for adults is 2.4 micrograms. However, many experts suggest that vegans aim for higher doses, often between 25-100 micrograms daily, or a weekly dose of 2000 micrograms.
This higher dosage accounts for potential absorption issues. B12 absorption becomes less efficient at higher doses, so taking more than you need ensures your body gets what it needs.
For example, while you might absorb 50% of a 1 microgram dose, you may only absorb 1% of a 1000 microgram dose.
Keep in mind that B12 is water-soluble, meaning excess amounts are generally excreted in urine. This makes it difficult to overdose on B12, although extremely high doses can cause side effects in some people.
Monitoring Your B12 Status
Regular blood tests are crucial for vegans to watch their B12 levels. However, don’t rely solely on serum B12 tests, as they can be misleading.
A person can have normal serum B12 levels but still be functionally deficient.
Ask your healthcare provider to include tests for methylmalonic acid (MMA) and homocysteine levels for a more accurate picture of your B12 status. Elevated levels of these compounds can indicate a functional B12 deficiency, even if serum B12 levels appear normal.
The Energy Connection: B12 and Your Cells
B12 plays a critical role in the mitochondria, the energy-producing structures within our cells. By ensuring adequate B12 levels, you’re directly supporting your body’s energy production at the cellular level.
B12 is involved in the metabolism of fatty acids and amino acids, which are used to produce energy. It also plays a role in the production of succinyl-CoA, a compound necessary for the citric acid cycle, a key process in cellular energy production.
This is why B12 deficiency often manifests as profound fatigue and weakness. Without adequate B12, your cells simply can’t produce energy efficiently.
Beyond Energy: The Far-Reaching Benefits of B12
While we’ve focused on energy, adequate B12 levels also support:
- Cognitive function and mental clarity: B12 is crucial for the health of your nervous system, including your brain. It helps maintain the myelin sheath that surrounds and protects nerves, allowing for efficient transmission of nerve signals.
- Mood regulation and emotional well-being: B12 is involved in the production of serotonin, a neurotransmitter that regulates mood. Low B12 levels have been associated with depression and other mood disorders.
- Cardiovascular health: B12, along with folate and B6, helps regulate homocysteine levels. High homocysteine is a risk factor for heart disease and stroke.
- Healthy pregnancy outcomes: Adequate B12 is crucial during pregnancy for proper fetal development, particularly of the nervous system. Vegan mothers need to be especially vigilant about their B12 status.
- DNA synthesis and red blood cell formation: B12 is necessary for the production of DNA and the formation of red blood cells.
Without enough B12, you can develop anemia, leading to fatigue and weakness.
Putting It All Together: Your B12 Action Plan
- Choose a high-quality vegan B12 supplement that suits your preferences and lifestyle. Whether you prefer sublingual tablets, sprays, liquids, or gummies, find a form that you’ll consistently use.
- Set a consistent supplementation schedule to ensure you don’t forget. Many people find it helpful to take their B12 at the same time each day, such as with breakfast or before bed.
- Incorporate B12-fortified foods into your diet as an extra boost. While these shouldn’t be your primary source of B12, they can help contribute to your overall intake.
- Schedule regular B12 blood tests to watch your levels. Aim for at least annual testing, or more often if you’re new to veganism or have had low levels in the past.
- Pay attention to your energy levels and other potential signs of deficiency. If you’re experiencing unexplained fatigue, weakness, or cognitive issues, ask with a healthcare provider.
- Consider working with a registered dietitian who specializes in vegan nutrition. They can help you create a comprehensive nutrition plan that ensures you’re meeting all your nutrient needs, including B12.
- Educate yourself about B12 and stay informed about new research. Our understanding of nutrition is constantly evolving, and staying up-to-date can help you make the best decisions for your health.
- Be an advocate for B12 awareness in the vegan community. Many new vegans are unaware of the importance of B12 supplementation, and sharing your knowledge can help others maintain their health on a plant-based diet.
By prioritizing your B12 intake, you’re not just supporting your energy levels – you’re investing in your overall health and well-being as a vegan. Remember, B12 supplementation is a smart, proactive approach to thriving on a plant-based lifestyle.
While B12 is a critical nutrient for vegans, a high-quality multivitamin can provide additional peace of mind. Discover some of the top choices in our guide to the Best Multivitamins for Vegans.
