Vitamin B12, also known as cobalamin, is one of 13 essential vitamins that the human body cannot operate properly without. It has a number of super important functions, among the most notable being nervous system development, red blood cell formation, and DNA synthesis. Especially important for athletes, B12 also serves an important role in energy metabolism and even affects digestion, leaving its mark on how you absorb foods. Common food sources of vitamin B12 include tuna, salmon, clams, beef, milk, yogurt, eggs, and fortified cereals. The recommended daily intake for adults is 2.4 micrograms, with pregnant and lactating women needing slightly more, which is why many prenatal vitamins include B12.

The two populations at the highest risk for vitamin B12 deficiency are older adults and vegans. In older adults, this is due to a reduced ability to absorb B12, whereas in vegans it’s due to a lack of dietary sources. Signs of deficiency include mild anemia (low red blood cells), fatigue, pale skin, and weight loss. Deficiency is rare because the body can store B12 for years.

As it may be difficult for some people to meet their B12 needs from diet alone, they may want to take a supplement. Vitamin B12 supplements come in a variety of forms. Which you choose is a matter of preference. To help you select the right B12 supplement for you, the ACTIVE Reviews Team has done the work for you, identifying the best B12 vitamins of 2023.

What to Consider When Shopping for B12 Vitamins

There are a number of things that should not be overlooked when you’re shopping for a B12 supplement. Here are the main factors to keep in mind when browsing the web for B12.

Chemical Form

B12 supplements come in a few different forms. It’s important to know the differences between them and which is best for you. The main forms found in supplements include cyanocobalamin and methylcobalamin. The former, cyanocobalamin, is synthetic and must be converted in the body before it can be utilized. The latter, methylcobalamin, is a more naturally occurring form and does not need to be converted in the body, making it slightly better absorbed.

Method of Administration

In addition to the different chemical forms, B12 also comes in several physical forms, including capsules, gummies, chewable tablets, sublingual lozenges, nose spray, and liquid. They even come in an injectable form, though this would have to be administered by a qualified healthcare provider. While the nose sprays and injectable B12s are the best absorbed, there is not much of a difference in absorption among the over-the-counter versions. Therefore, you’ll have to decide which form of administration you prefer.


The proper dose of Vitamin B12 will vary by your age, gender, and specific reasons for taking it. You only need 2.4 micrograms per day, and when you supplement with B12, your body can actually absorb only a small percentage of the dose. Even so, B12 supplements typically provide anywhere from 250-5,000 micrograms. The best way to determine the proper dose is to have your blood B12 levels checked to see how low they are. Your doctor may then recommend a specific dose. In general, if you are looking to take B12 preventatively, it’s best to start with a lower dose of 250-1,000 micrograms. Try using a pill organizer to make sure you take the proper dosage consistently each day.

While most B12 supplements provide anywhere from 250-1,000 micrograms per dose, higher supplementation is warranted sometimes. Specifically, if you’ve had your blood B12 tested and it comes back low, your healthcare provider may suggest taking a higher dose supplement to get your B12 back to normal.

Benefits of B12

Vitamin B12 plays an important role in nervous system development, red blood cell formation, and DNA synthesis. It’s especially important for athletes due to its function in energy metabolism, and it even affects how we absorb nutrients from food. Considering B12’s vital role in the formation of red blood cells, which carry oxygen throughout the body, it’s a particularly key nutrient for endurance athletes.

Why We Need B12

Without vitamin B12, our brain and nerve cells would not be able to function or continue to develop properly. Our red blood cells would become enlarged and unable to carry oxygen efficiently through our bodies. Plus, we wouldn’t be able to properly metabolize nutrients from food, leading to fatigue and potential deficiencies.

How to Pick Your B12 Vitamin

The first factor to consider when choosing a vitamin B12 supplement is which form you would prefer, a capsule, tablet, liquid, lozenge, etc.? Think about which you would be most likely to take on a consistent basis. From there, find a brand that provides the proper dosage to meet your needs based on recommendations from your healthcare provider. Finally, consider your budget. How much would you ideally like to spend per dose or container? Taking these factors into consideration will enable you to choose the best B12 supplement for your individual needs.

FAQs About Vitamin B12

Which form of vitamin B12 is best?

The most common forms of B12 found in supplements are methylcobalamin and cyanocobalamin. The former is a more naturally occurring substance that is more quickly absorbed, whereas the latter is a synthetic version that requires a bit of extra processing in the body to be utilized. Experts will often recommend the methylated form if you are looking to maximize absorption, although the synthetic version can also maintain your B12 levels in most cases.

Is it okay to take B12 every day?

B12 has a low risk of toxicity and is safe for most people to take every day. If you are unsure of your B12 levels, it may be worth it to have them checked first before supplementing. It’s always better to start with a lower-dose B12 supplement rather than jumping right to the highest dose possible. As always, you’ll want to check with your healthcare provider before you start taking such a supplement.

What foods have B12?

The most common food sources of B12 are tuna, salmon, clams, beef, milk, yogurt, eggs, and fortified cereals. When it comes to plant-based options, most vegans and strict vegetarians get their B12 from nutritional yeast and plant-based foods that are fortified.
