The Ultimate Buyer’s Guide to the Best B12 Supplement

Vitamin B12 or cobalamin is one of the most essential vitamins the body needs to perform a number of vital processes. It supports cognitive function, the production of red blood cells, DNA synthesis, as well as brain and heart health. Since the body doesn’t produce B12, you must get it through food and supplements. But before you start ordering B12 vitamins online, there are few things to consider. 

Why is this vitamin so important? How serious is B12 deficiency? And most importantly, how to choose the best vitamin B12 supplement for you? Check out our guide for the answers and more. 

Benefits of Vitamin B12

Vitamin B12 is known to:

  • Increase energy levels
  • Boost memory and cognitive abilities 
  • Improve mood 
  • Promote bone health 
  • Prevent anemia
  • Support eye health and lower the risk of macular degeneration 
  • Support a healthy pregnancy 
  • Promote healthy skin and hair 

Sources of Vitamin B12

B12 is commonly found in animal-based products, such as fish, meat, eggs, and dairy. Some fortified cereals and nutritional yeast products can also provide the body with B12. However, the amounts might not be enough to meet adult cobalamin requirements. 

Signs of a B12 Deficiency

Here are some of the most common signs that you need to take a high-quality vitamin B12 supplement:

  • Weakness and fatigue
  • Loss of appetite 
  • Megaloblastic anemia
  • Depression
  • Cognitive and balance issues 

B12 deficiency can affect anyone, no matter how much vitamin-rich food you eat. In fact, it’s estimated that between 1.5% and 15% of the general population have a B12 deficiency. Still, certain groups might need B12 vitamins and supplements more than others. These include:

  • Older adults 
  • People with stomach and gastrointestinal issues
  • Patients recovering from gastrointestinal surgeries 
  • Vegans and vegetarians 
  • Those taking medication for chronic heartburn

How to Choose the Best B12 Supplement for You?

Let’s take a look at the factors you need to consider when choosing the best vitamin supplement for you or your family member.

Delivery Method

Vitamin B12 supplements come in several forms, from traditional tablets to chewable lozenges and sublingual sprays. 

  • Capsule-based supplements are the most commonly used. They deliver an accurate dosage each time, so there is no need to worry about underdosing. However, pills are not everyone’s favorite. Even the best B12 tablets might be hard to swallow, especially for the elderly, who are most likely to suffer from vitamin B12 deficiency in the first place. 
  • Gummies, like capsules, deliver a consistent dosage with each piece but are much easier to consume due to their candy-like nature. The downside is that other ingredients are often involved in the manufacturing of gummies, including artificial sweeteners, colors, and flavors, which doesn’t exactly make them the best natural B12 supplement. 
  • Liquid supplements are an excellent choice for people who want to get their daily dose of B12 with their morning protein shake. Some B12 liquid supplements are designed to be taken sublingually (under the tongue). Although these are the most bioavailable options, you should be careful with dosing. Unlike tablets and gummies, with liquids, you have to rely on the dropper, which is not always the most accurate dosing method. 

All forms of B12 have advantages and disadvantages. In the end, it’s up to you to choose the best type of B12 depending on preferences, budget, and convenience. 

The Right Dosage 

The recommended daily allowance for adults is 2.4 mcg. Bear in mind that this is the minimum recommended amount, so don’t be alarmed if you see a higher dosage on the supplement packaging. B12 is generally safe even when taken in larger doses. Like other water-soluble vitamins, the body will excrete the amount it can’t absorb through the urine. Nevertheless, you should always discuss possible side effects and dosage with your doctor before taking any supplements.  

Other Ingredients

The best B12 supplements should only contain pure and effective ingredients. Steer clear of fillers, GMOs, and allergens, such as wheat, soy, or nuts. Try to go for organic compounds and stick to clean and simple formulas that will provide the right dosage of B12 without any unnecessary ingredients thrown in the mix. 

Price 

The price of a high-quality B12 supplement ranges between $14.99 and $29.95. You could even get the vitamins for less if you take advantage of deals and other buying perks. Most supplement manufacturers offer seasonal sales, coupon codes, and discounts on bundles, so make sure you check out all the company’s offers before clicking the order button. 

User Experiences

Always look at what other customers are saying about the product. B12 supplement reviews will tell you pretty much everything about the effects of the vitamins, as well as provide you with insight into the manufacturer and its policies and practices.

Wrapping It Up

We understand how overwhelming it could be to find a good B12 supplement. Available products on the market range from low-dosage tablets to high-potency liquids and sprays, making the selection process quite challenging. We hope that our reviews of the best supplements have helped narrow down your choice to one premium product that will meet all your B12 needs.

FAQs

What is the best time to take a B12 supplement?

Since B12 boosts energy and cognitive abilities, it’s best to take the supplement in the morning on an empty stomach and start your day the right way. 

What is the best mcg of B12 to take?

The recommended daily dose is 2.4 mcg, although you can safely take higher doses as the body will excrete any excess.  

How much B12 should you take a day?

Most supplements contain between 500 mcg and 1,000 mcg per serving, which is more than enough to tackle B12 deficiency. 

Which form of vitamin B12 is best?

B12 supplements are usually derived from two sources — cyanocobalamin or methylcobalamin. These two compounds have a similar molecular structure, but the most significant difference is that methylcobalamin is naturally found in food, while cyanocobalamin is a synthetic form of B12. Even though both have the same effects (they can both prevent B12 deficiency), methylcobalamin is the preferred form of the best B12 supplement as it has a higher retention rate and is natural rather than man-made.
