The 10 Best Vitamin B12 Supplements

We all know that vitamins and minerals are important in our diet and many of us try to include a variety of fruits and vegetables to ensure we get them. Some of us take multivitamin supplements. Yet you may find yourself feeling weak and overcome with fatigue. This may be due to many causes, but one unexpected reason may be a vitamin B12 deficiency.

You’ll probably be surprised to find just how common vitamin B12 deficiency is. No, none of the vegetables and fruits you consume have any vitamin B12 though there may be other B-vitamins present in them. This is the primary reason why vegans and vegetarians tend to be more deficient in this vitamin compared to non-vegetarians. Yes, vitamin B12 is found in plenty in animal-sourced foods such as beef, chicken, fish, eggs, and milk. Clams and beef liver are said to be among the best sources of vitamin B12.

But if you do not like such food sources of vitamin B12, have no worries as this is easily available in the form of dietary supplements. Rather than a general multivitamin that may or may not contain any B12, make sure to choose one that offers you adequate vitamin B12.

But what if you are a non-vegetarian and you still suffer from vitamin B12 deficiency? So before moving on to a list of the top 10 vitamin B12 supplements, let’s take a look at why we all probably need to take B12 supplements, especially those over 50 years of age.

Why Use Vitamin B12 Supplements

Even if they eat the right foods, some people have trouble absorbing this vital vitamin from their food sources. Vitamin B12 deficiency affects approximately 15% of the population. Older adults, over 50 years of age, may not produce enough hydrochloric acid in the stomach, which is necessary for the absorption of vitamin B12.

People suffering from pernicious anemia, a condition where the intrinsic factor required to absorb this vitamin is not produced in the body. This is usually treated with vitamin B12 injections or high oral doses of the vitamin.

Those who have undergone gastrointestinal surgery or have digestive disorders such as celiac disease or Crohn’s tend to have reduced capacity to absorb this essential nutrient. A medical check-up can help determine if a deficiency in B12 vitamin is present.

Nursing babies of vegetarian and vegan mothers also may not get sufficient amounts of this vitamin. Pregnant women who do not consume animal-based foods may not be supplying enough vitamin B12 to their unborn child and this can lead to neural tube defects in the fetus. So supplementing with vitamin B12 along with folic acids is important in the initial months of pregnancy to ensure proper development of the brain and spinal cord.

Now let’s have a look at the top 10 vitamin B12 supplements available online.

The Dosage and Side Effects of Vitamin B12

The amount of vitamin B12 intake depends upon the age of the individual. Pregnant and breastfeeding moms require more vitamin B12 than their counterparts.  While children below 8 require about 1.2 mcg of vitamin B12 per day, this doubles to about 2.4 mcg when they hit their teens.

Adults also require only 2.4 mcg per day while pregnancy raises this requirement to 2.6 daily. Breastfeeding moms have the highest requirement at 2.8 mcg of vitamin B12 every day.

Now, most people have a major and valid confusion – If we require just 2.4 mcg of vitamin B12 a day, why do B12 supplements offer absurd amounts of 1000 to 5000mcg of this vitamin. Researchers have observed that only about 2% of vitamin B12 is absorbed by the body from supplements.

A 2008 study recorded that just 9.7 mcg of vitamin B12 was absorbed from the administration of a 500 mcg supplement. Other studies have also noted that intake of over 1000 times the recommended vitamin B12 had no major side effects. This is because vitamin B12 is water-soluble and excess vitamin B12 is flushed out of your body through your urine.

The Final Note

Vitamin B12 has many important roles in the healthy functioning of the human body including DNA synthesis and the production of oxygen-carrying red blood cells. Any deficiency of this vitamin in your body can cause a host of health issues from fatigue and weakness to skin hyperpigmentation and even memory loss.

Though vitamin B12 can be naturally found in animal foods such as fish, chicken, eggs, and dairy, vegans and vegetarians may find themselves deficient as plants tend to lack this vitamin. B12 deficiency is also common among the elderly due to reduced absorption that results from the natural decrease in stomach acids.

Foods fortified with vitamin B12 or vitamin B12 supplements help overcome such deficiencies. Make sure to choose a supplement from a reputed manufacturer. Supplements with Methylcobalamin (Methyl B12) tend to have more bioavailability than other forms of vitamin B12.
