3 minute read – This article talks about what B12 is, why it’s important, where you get it from, and if  B12 injections can help boost levels of this important vitamin. 

In a world where energy is currency, maintaining optimal health is crucial. At the heart of this quest is Vitamin B12, a powerhouse nutrient that fuels our bodies, supports brain health, and aids in the production of DNA and red blood cells. 

But what exactly is B12, and why is it so essential for our energy levels and overall well-being? That’s a great question! You probably see it on the back of your foods in the nutrition information and perhaps on our supplements if you happen to take them, but you might not really know what it is or why it’s so critical to how you feel. 

Today we thought we’d look at all things B12, from what it is to how it works and where you get it in your daily diet. 

What is Vitamin B12?

Vitamin B12, scientifically known as cobalamin, is a water-soluble vitamin crucial for various bodily functions. It’s unique among vitamins because it contains a metal ion, cobalt. B12 is essential for brain function, nerve tissue health, and the creation of red blood cells. It’s a vitamin that our body cannot produce on its own; hence, it must be consumed through diet or supplements.

Benefits of B12

The benefits of Vitamin B12 are vast. It plays a vital role in the production of DNA, the genetic material in all cells. B12 is also critical for the proper formation of red blood cells, preventing a type of anemia that can lead to weakness and fatigue. For the nervous system, B12 maintains the health of nerve cells and helps in the formation of the protective covering of nerves, known as the myelin sheath. Without sufficient B12, one might experience memory loss, fatigue, and, in severe cases, neurological changes.

How B12 Helps with Energy

Many of us reach for a cup of coffee when we feel tired, but ensuring adequate levels of Vitamin B12 could be the key to sustained energy. B12 is instrumental in converting the food we eat into glucose, the body’s primary energy source. This process is crucial for maintaining energy levels throughout the day. Moreover, B12 plays a significant role in reducing fatigue by participating in the synthesis of neurotransmitters related to mood regulation and energy, such as serotonin and dopamine. This means that adequate levels of B12 not only help in keeping our energy up but also in maintaining our mental health.

Sources of Vitamin B12

Vitamin B12 is naturally found in a wide range of animal products, including meat, fish, poultry, eggs, and dairy products. This poses a challenge for vegetarians and vegans, who might find it difficult to get enough B12 from diet alone.

Animal sources of B12: 

  • Meat
  • Beef, especially liver
  • Pork
  • Chicken
  • Lamb
  • Seafood
  • Salmon
  • Tuna
  • Trout
  • Sardines
  • Clams
  • Mackerel
  • Crab
  • Oysters
  • Dairy Products
  • Milk
  • Cheese, especially Swiss and mozzarella
  • Yogurt
  • Eggs
  • Particularly the yolks
  • Fortified Foods (for those on a vegetarian or vegan diet)
  • Breakfast cereals
  • Nutritional yeasts
  • Plant-based milk (soy, almond, oat, etc. that are fortified)
  • Meat substitutes that are fortified with B12

For vegans, getting enough Vitamin B12 requires a bit more attention since B12 naturally occurs in animal products. Here’s a list of vegan-friendly sources of B12:

Fortified Foods: These are the primary sources of B12 for vegans and include:

  • Fortified non-dairy milks (such as almond, soy, rice, and oat milk)
  • Fortified nutritional yeast (popular as a cheese flavor substitute)
  • Fortified breakfast cereals
  • Fortified meat substitutes


  • Vitamin B12 supplements (available as tablets, capsules, and sometimes in liquid form)
  • Multivitamins that contain B12

Other Sources:

  • Certain types of fortified vegan spreads
  • Fortified vegan yogurts

It’s important for vegans to read labels carefully to ensure that the products are indeed fortified with Vitamin B12. Consulting with a healthcare provider about B12 supplementation is also advisable to tailor intake to individual health needs and ensure adequate absorption.

Benefits of B12 Injections

While diet and oral supplements are one way to improve overall B12 levels, B12 injections can also be a great way to quickly boost your B12 levels. B12 injections bypass the digestive system, allowing for direct absorption into the bloodstream and providing an immediate boost to B12 levels. This method can be particularly helpful for quickly correcting deficiencies, improving energy levels, cognitive function, and overall vitality.

In fact, getting B12 Injections is the most effective way to treat a documented B12 deficiency. Those looking for a sure fire way to boost energy, increase brain function, and increase their B12 levels should consider B12 injections.

Vitamin B12 is a cornerstone of our health, playing a pivotal role in energy production, neurological function, and red blood cell formation. Whether through dietary sources, supplements, or injections, ensuring adequate B12 intake is essential for maintaining energy levels, supporting mental health, and preventing a range of health issues. By prioritizing B12 in our diet, we can unlock a more energized, healthier version of ourselves, ready to tackle the challenges of daily life.
