Vitamin B12: From Capsules to Injections, What's the deal with B12?

Vitamin B12 seems to be everywhere. From the shelves of your local pharmacy to your favorite health food cereal. Now clinics are even giving injections to patients to bolster their daily intake. But what is B12, and what are the benefits of taking it?


B12 is an essential vitamin that our body needs but cannot produce. Vitamin B12 is naturally found in animal products, including fish, meat, poultry, eggs, milk, and milk products, but is generally not present in plant foods. B12, along with other Essential B Vitamins, help with cell growth & development and breakdown of carbohydrates, fats, and alcohol. B Vitamins are the building blocks for a healthy neurologic and cardiovascular system.

B12 is a critical part of red blood cell production, neurologic system function, regulating energy levels affecting sleep and mood, and many others. Deficiencies in vitamin B12 can lead to megaloblastic anemia, difficulties in proprioception and spinal cord function, and insomnia and fatigue.

Because B12 is such an essential part of how our body functions, B12 deficiency can cause various problems. It's also important that vegetarians and vegans should especially supplement B12 because it is not readily available in plants.

The benefits of B12 include:
- Metabolism & Energy: Boosts your body's energy production and helps the body covert fats and proteins into energy.
- Immune System: Enhances immune systems response to ward off pathogens.
- Cognitive Function: Helps maintain vital nerve health, including neurotransmitters in the brain. When B12 drops, so can brain function.
- Sleep: B12 deficiency can alter sleep patterns and make it difficult to fall asleep and stay asleep.
- Healthy Skin and Nails: Enhances beauty by promoting healthy hair, skin and nails and reduces redness, inflammation, and dryness.

B12 is essential to promoting a healthy lifestyle and body. Foods rich in vitamin B12 include beef, venison, turkey, shellfish, and other fish such as salmon, trout, and sardines. If you don't eat those foods or want to supplement anyway to ensure you get enough vitamin B12 try Seeking Health's Active B12 with L-5MTHF (click here to view). Even if you do commonly consume meat, its challenging to know how much B12 you are getting so this may be an excellent solution for you too.


Along with B12 is it also important that there are an array of B-complex vitamins including B1, B2, B6, and folate. These vitamins also help maintain healthy blood pressure levels, boost learning and memory, and can even protect against depression, anxiety, and heart disease. A surprising source of B vitamins and a plethora of other nutrients is organ meat or offal. Although this may seem off-putting to some, in history and still today many cultures consume the entirety of an animal, not just the muscle and fat of certain parts. In fact, the heart, kidney, and liver are great sources of vitamins that are hard to beat, and many cultures around the world have traditional dishes based around them. Humans used to eat it out of necessity, but even with all the supplements available today, it is still hard to beat. Liver, for example, has more than double the daily-recommended value for vitamin A and vitamin B12, and some believe it is one of the most nutritious foods you can eat when it comes to vitamins. But it is extremely important to choose good sources of this meat, meaning choosing healthy animals, like grass-fed animals, who in turn have healthy organs. It can be easy to incorporate it into your diet, and for example, you can buy grass-fed ground beef that also has heart, liver, and kidney. It might sound intimidating, but the blend all-together is so nourishing.  

There are many different ways to get these essential B vitamins, including B12, but it goes without saying that many of us are not aware of how we intake B12 or whether we are getting enough. Proper nutrition from food along with supplementing to ensure you are getting the nutrients your body needs is a great way to promote a healthy lifestyle.
