The Best B12 Supplement: The Energy Vitamin 


Finding the best vitamin B12 supplement can be difficult. You require a certain amount of macro-nutrients and micro-nutrients for optimal functioning, based on your own metabolic rates. While it’s easier to meet your daily recommended levels of macro-nutrients from a balanced meal, you most likely skip on the extremely crucial micro-nutrients such as vitamins and minerals. Vitamin B12 is one micro-nutrient that requires particular attention when it comes to maintaining your health and well being. Here at The Nutritional Source I compiled a review of the best B12 supplements to help boost your energy each day. 

When your car needs fuel, you feed it gasoline. When your body needs fuel, you need to feed it the best B12 supplement that’s right for you.


Vitamin B12 (Cobalamin) is one of the 8 water-soluble B vitamins. It is naturally present in some foods as well as being a dietary supplement or a prescription medication in some cases.


Vitamin B12 is commonly referred to as the powerhouse vitamin since it fuels some of your body’s most crucial functions. These functions include:


  • Proper red blood cell formation
  • Neurological function
  • DNA synthesis
  • Maintaining optimum brain and heart health


Vitamin B12 has many benefits for improving bodily functions as well as helping with hair growth and weight loss.


What To Look For In The Best B12 Supplement


It’s crucial to pick out the best B12 supplement to suit your specific requirements, but it’s also important to note some supplementary key factors that go into selecting the right vitamin B12 supplement. Note that people absorb vitamins and minerals at different rates from both foods and supplements.


You may take all possible types of vitamins and minerals orally, but if your body can not absorb them properly, these nutrients will go to waste.


There are two forms of vitamin B12 that you’re likely to come across while shopping for vitamin B12 supplements namely methylcobalamin and cyanocobalamin.


These two are similar forms of the vitamin B12s, but the only difference is that methylcobalamin contains a methyl group. Whereas cyanocobalamin has a cyanide group in its molecular composition.






Methylcobalamin is the natural, active form of B12 that can easily be absorbed by your body.


Cyanocobalamin, on the other hand, is a synthetic compound that your body must convert to methylcobalamin before it’s useful.


Moreover, this conversion releases very small quantities of cyanide (extremely harmful compounds) into your body.


Methylcobalamin is the natural form of vitamin B12 that is safer for ingestion. It is upheld with the ability to stay active and available in your system for longer periods of time compared to cyanocobalamin.


Keeping all these factors in mind, methylcobalamin becomes an indispensable part of the attributes to look for when searching for the best B12 supplement.


Sometimes the rate of absorption may increase by simply selecting the right mode of administration of these vitamins, instead of making major changes with its dosage.


This is true with vitamin B12. It is available in many different forms:


  • Oral supplements such as sprays and lozenges – referred to as sublingual B12
  • Injections/ Shots
  • Nasal gels and sprays
  • B12 patch


Among all of the above-mentioned forms of administration, sublingual B12 tablets are becoming more popular than ever.


As the name suggests, these sublingual B12 pills are to be placed under your tongue until they completely dissolve into your mucosal membrane.


There are many advantages of taking sublingual B12 pills and choosing the best B12 supplement which include:


  • Bypassing the gastrointestinal tract due to direct absorption into your blood stream. This allows higher concentrations of vitamin B12 that are readily available.
  • It is less invasive (no needles involved).
  • No nurse or supervision is required for assistance with supplementation.
  • Quick and easy as compared to skin patches that have to be worn for 24 hours.


The best B12 supplement checklist:


  1. Buy the best B12 supplement for you and avoid fortified or processed foods
  2. Choose methylcobalamin forms
  3. Stick with a sublingual spray or liquid form
  4. Choose the correct dosage that you require


If you are new to the world of supplementation, then all of the names, dosage amounts and forms (liquids, tablets or powders) of vitamin B12 supplements are likely to make you feel a bit overwhelmed.


So, which ones should you choose and what’s the best option?


Here’s a table of the top 10 vitamin B12 supplements put together by me to assist you in making the best decision while looking for your B12 supplement.

How Much Vitamin B12 Should I Take?


According to Dr. Axe, the Recommended Dietary Allowance (RDA) for vitamin B12 is 2.4 mcg/day with a Daily Value (DV) of 6 mcg/day.


But… in my article of the best B12 supplement, all contain anywhere from 1,000mcg to 10,000mcg? So why would I need to take that much, right?


The answer is that your body doesn’t absorb 100% of vitamin B12.


The basic doses offered in many vitamin B12 supplements are enough to cover your RDA for vitamin B12 for the majority of users.


Those of you suffering from diseases or with a severe vitamin B12 absorption disorder are often advised, however, to take vitamin B12 in high doses. Hence, the reason why you are reading this article probably.


The term ‘high dose’ here means a vitamin B12 dosage of around 1000mcg. This corresponds to over 30,000% of the official recommended 3mcg daily dosage given by the Dietary Guidelines for Americans, which suggests to be a massive overdose.


However, the actual intake of vitamin B12 is a much more relative figure: of the 1000mcg taken in one oral dose, a maximum of 12mcg is actually absorbed by your body – which is only around 400% of the recommended dietary allowance per day.


The human body is not equipped to produce vitamin B12 naturally, therefore the best way to replenish your B12 levels is by consuming foods that are rich in vitamin B12. Or you can begin taking some of the best B12 supplements to help too.


Here is a list of foods that provide an abundant amount of vitamin B12:




It becomes particularly difficult for vegans and vegetarians to obtain their daily dosage of vitamin B12 from food sources. The majority of foods rich in vitamin B12 are animal products like eggs, meat, shellfish, and dairy.


Unfortunately, even babies who have vegetarian mothers may suffer from vitamin B12 deficiencies.


Why Is Vitamin B12 Important?


Recent studies show that around 40% of Americans are vitamin B12 deficient. While a mild deficiency may cause no symptoms, prolonged and untreated deficiencies can lead to symptoms as severe as impaired mental function and low energy levels.


Other vitamin B12 deficiency symptoms include:


  • Weakness
  • Heart palpitations and shortness of breath
  • Anemia
  • Loss of appetite
  • Numbness or tingling of nerves and muscle weakness
  • Vision loss
  • Depression, memory loss or behavioral changes


The National Health and Nutrition Examination Survey indicated that more than 3% of adults over age 50 have extremely low levels of vitamin B12. The survey also suggested that up to 20% of these older adults may have borderline levels of vitamin B12, making it essential to supplement their needs through other alternative means.


For most people, these symptoms can be overcome by consuming the best B12 supplement. Other ways include taking a multivitamin that contains the recommended daily allowance of vitamin B12.

Use Cautiously 


The U.S. FDA does not strictly regulate all vitamin B12 supplements. Therefore, there is no guarantee of potency, purity or safety of the products. The effectiveness of the product may vary from person to person.


Reading the product labels before purchasing any Nutrition Supplement is important.


If you are already suffering from a medical condition or are taking medications for a particular condition, you should consult your physician before starting a new supplement in order to avoid unnecessary drug interactions.


Those suffering from B12 and cobalt allergies, as well as pregnant or lactating mothers, should steer clear from such supplements.


Lastly, it is extremely essential to keep in mind that the best vitamin B12 supplement should be consumed within the recommended daily intake levels to avoid any adverse side effects.
