Our “WOW Factor” Buyer’s Guide

You might be wondering if you need to take a Vitamin B12 supplement. Not getting enough Vitamin B12 can lead to some serious health problems.

The best way to make sure you're getting the vitamin b12 you need is by taking a supplement. But with so many on the market, which one should you choose?

Here are the most frequently asked questions about Vitamin B12 Supplements and our answers to them.

Which form of vitamin B12 is best?

There are a few different forms of vitamin B12, but the most common form is cyanocobalamin. Some people prefer to take methylcobalamin or hydroxycobalamin because they believe that they are more bioavailable, but there is no scientific evidence to support this claim. In fact, the overall absorption of vitamin B12 from all forms is about the same.

Which is the best tablet for vitamin B12 deficiency?

There is no one-size-fits-all answer to this question, as the best tablet for vitamin B12 deficiency will vary depending on the individual's specific needs.

However, some of the most common tablets used to treat vitamin B12 deficiency include cyanocobalamin, methylcobalamin, and hydroxocobalamin.

What is the healthiest way to get vitamin B12?

Vitamin B is an essential element that the body needs for several important functions. It helps to make DNA and red blood cells, and it is also involved in the metabolism of both fat and protein. vitamin B can be found naturally in a variety of food sources, including meat, fish, poultry, eggs, and dairy products.

Supplemental forms of vitamin B12 are also available for people who may not be getting enough of the vitamin through their diet. Vitamin B12 supplements are available in both capsule and tablet form, and they can also be found in injectable form.

Which B12 is better methylcobalamin or cyanocobalamin?

There is no consensus on which form of vitamin B12 is better, methylcobalamin or cyanocobalamin. Some people believe that methylcobalamin is a more active form of the vitamin, while others believe that cyanocobalamin is more easily absorbed by the body.

Is it OK to take 1000 mcg of B12 daily?

Yes, it is perfectly safe to take up to 1,000 mcg of vitamin B12 daily.

Vitamin B12 is a water-soluble vitamin that is stored in the body, so it is very unlikely that you would reach toxic levels even if you took much more than the recommended amount.

However, there is no need to take such high doses of B12 unless you have a medical condition that requires it.

What are the symptoms of low B12?

Low B12 can cause a wide range of symptoms, including:



-loss of appetite

-weight loss


-numbness or tingling in the hands and feet

-difficulty walking


-memory problems



If you experience any of these symptoms, it is important to see your doctor as soon as possible. Low B12 levels can be easily treated with supplementation but left untreated, they can lead to more serious health problems.

What are the best foods to eat if you have low B12?

There are a variety of foods that are rich in vitamin B12, including beef, liver, eggs, fish, poultry, and dairy products.

If you have low B12 levels, it is important to eat foods that are rich in the vitamin or to take a supplement.

Can you take too much vitamin B12?

Vitamin B12 is an essential vitamin, meaning that the body needs it to function properly. Unlike some other vitamins, the body does not store vitamin B12, so it is important to get a regular supply through diet or supplementation.

While it is possible to take too much vitamin B12, this is generally only a concern for people taking supplements or eating fortified foods. Getting too much vitamin B12 from natural sources is unlikely.

Symptoms of vitamin B12 toxicity are rare and may include liver problems, diarrhea, and nausea. If you are concerned that you are getting too much vitamin B12, talk to your doctor or a registered dietitian.

What are the side effects of taking B12?

The most common side effect of taking B12 is gastrointestinal upset, such as abdominal cramping, gas, and diarrhea. Some people may also experience headaches, fatigue, or dizziness.

If you experience any of these side effects, it is generally recommended to reduce your dosage or stop taking B12 supplements altogether.

Speak with your doctor if you have any concerns. Long-term use of high doses of B12 has been linked to liver damage and depression, so it is important to be cautious when taking this supplement.

Who should not take vitamin B12?

Anyone who has pernicious anemia or any other type of anemia should not take vitamin B12.

People with kidney disease or any other serious illness should speak to their doctor before taking this vitamin.

Smokers and heavy drinkers should also avoid taking Vitamin B12.

Pregnant women and young children are also advised not to take this supplement.

Does vitamin B12 affect your heart?

Yes. The heart needs vitamin B12 to function properly. Vitamin B12 is important for the production of red blood cells, and a lack of it can lead to anemia. Anemia can cause heart problems because it reduces the amount of oxygen that reaches the heart muscle.

A lack of vitamin B12 can also lead to a condition called coronary artery disease. In coronary artery disease, the arteries that supply blood to the heart muscle become diseased and narrowed, which reduces the amount of blood that can reach the heart. This can cause chest pain (angina) and other symptoms such as shortness of breath and tiredness.

Our Best Advice

Looking for the best Vitamin B12 supplement? We’ve spent dozens of hours reading thousands of reviews on Amazon from verified customers to find the perfect B12 Vitamin for your needs.   Here are a few things to keep in mind.

First of all, it is important to keep in mind that vitamin b12 is what our body needs for energy metabolism, the production of healthy red blood cells, and a healthy central nervous system.  Normally this would come from animal products (meat, chicken, eggs, liver, etc) but sometimes our natural energy needs a boost in energy production, and taking a good b12 vitamin supplement is just what the doctor (or healthcare professional) ordered.

Second, if vitamin b12 is essential in converting food into energy for energy production and energy metabolism then it stands to reason that being low on energy probably means that you are low on vitamin b12.  But that is a normal situation to be in at certain times of the day (or the month).  When it becomes a more common occurrence is when a supplement may be necessary.  Red blood cell production in a healthy nervous system will happen automatically if you are eating a well-balanced diet.  But the human body sometimes needs something to support energy and vitamin b is the answer.

Vitamin b can help maximize the absorption of nutrients from blood as well as support other essential functions.  They can help regulate sleep-wake cycles, and support red blood cell formation and overall energy production.  They are useful for brain health, and heart health and play a vital role in maintaining healthy blood cells. Red blood cell formation is especially important to support energy for general well-being.  Folic acid from dietary sources that are biologically active (and include vitamin d) for brain function and heart health is also good in vitamin b12 supplements.

A good supplement brand (like Nature's Bounty) will make sure that they are certified USDA organic, and have no artificial flavors (their natural cherry flavor and other natural flavors are excellent).  They are third-party tested to maximize absorption for cellular energy, contain no tree nuts, and are dairy-free, sugar-free, soy-free, and gluten-free.  In addition, they only use high-quality ingredients in their vitamin b12 supplements.

For those who hate swallowing pills, one capsule is all you need per day for improved energy.  Other supplements (and other forms of betting the b vitamin) may not promote heart health and brain function with the same effectiveness.

Vitamin b12 supplements should contain no glucose syrup or citric acid since the b vitamin and citric acid should never be taken together.  For mature adults who want to promote heart health with one capsule per day in natural flavors (and did I say gluten-free?), Nature's Bounty is a good source of vitamin b.

I may have let the cat out of the bag already, but in any event, it is now time to reveal our top choice for the best of the best in b12 vitamin supplements.  Drum roll, please...
