Methyl B12 is a daily nutritional supplement produced by the German company Jarrow Formulas. According to the manufacturer, Methyl B12 can be useful for heart health, increasing energy, and memory function. The formula also promotes better sleep schedules and is critical for the DNA synthesis process.

As the name suggests, Methyl B12 includes only one active ingredient in the form of Methylcobalamin, a concentrated form of Vitamin B12, a critical component of a healthy and well-functioning body.

Methyl B12 by Jarrow Formulas is widely available online at an affordable price, reason why this supplement is so popular in the United States. In fact, Methyl B12 is one of the best selling vitamins on

Benefits of Methyl B12

Vitamin B12 (also known as cobalamin) is one of the most important chemicals in the body. Vitamin B12 is essential for surviving and proper functioning, and yet our body does not produce it on its own. So we need to get this vitamin from other sources.

Proper nutrition, as always, is highly recommended and it should be enough for most people. Red meat, dairy products, and fish are excellent sources of Vitamin B12. But when your diet is not balanced around these types of food, supplementation is required.

As stated above, Methyl B12 produced by Jarrow Formulas contains Methylcobalamin which basically is a better form of Vitamin B12. Methylcobalamin is thought to be better absorbed than other forms of B12, and it may help improve the regulation of homocysteine levels in ways that normal cobalamin can’t.

Methyl B12

Vitamin B12 is also needed for optimal mental performance as it plays a key role in the synthesis of various neurotransmitters and neuropeptides. It is also necessary for myelin production and maintenance, which is critical for learning. Because of all these, Vitamin B12 is a key component in most brain supplements available at this moment.

However, many complex formulas include only trace amounts of Vitamin B12 (there is a limit of how much of each ingredient you can actually include in one single capsule – the more ingredients you have, the less of each you can include). As we age, our body will have a harder and harder time processing Vitamin B12, often times necessitating extra B12 supplementation (even with a proper diet that includes all Vitamin B12 rich foods mentioned above). It is estimated that one in five women over the age of 50 is deficient in Vitamin B12.

B12 deficiencies have been linked to a number of symptoms that include heart palpitations, weakness, tiredness, loss of feeling, nerve issues, vision loss, depression, anxiety, constipation, and diarrhea.

On the other hand, there is a limit on how much Vitamin B12 our bodies can actually absorb, even under ideal circumstances. Methyl B12 contains a ridiculous amount of Methylcobalamin, which doesn’t translate into excess performance.

It is also worth mentioning that B12 is not effective as a performance booster or as a study drug and its beneficial effects will not be perceptible to the vast majority of people.

EDITOR'S TIP: Methylcobalamin is widely recognized as a superior form of Vitamin B12.

How Much Does Methyl B12 Cost?

Methyl B12 is an inexpensive and widely available supplement, which makes it a great option for those looking to combine two or more potent supplements.

Each bottle of Methyl B12 contains 100 capsules (enough for a full month of treatment) and it costs between $4.69 and $9.95, depending on the retailer.

The price is a bit above the average price for a basic vitamin supplement, but it’s far less than what you would have to pay for an effective nootropic supplement.

Potential Methyl B12 Side Effects

Vitamin B12 is likely safe when taken according to the recommended dietary amounts. People who are allergic to cobalt or cobalamin should avoid taking Vitamin B12.


Methyl B12 contains Methylcobalamin, which is a superior form of Vitamin B12;
Many positive reviews and testimonials available online;
Jarrow Formulas is a reputable German company;
Affordable price.


Methyl B12 contains an absurd amount of Methylcobalamin, which will not translate into better performances;
Some consumers have complained about potential side effects.

Final Verdict

Usually, we like to recommend a Vitamin B12 supplement only paired with a more effective nootropic agent. Vitamin B12 is crucial but not as effective when taken alone, as supplementation. Because natural B12 can easily be obtained through proper nutrition, supplementation with Vitamin B12 is not always necessary, and almost never in such high dose as the one provided by Methyl B12.

Nevertheless, Methyl-B12 does look like a good choice as it’s benefits are backed up by a huge number of positive reviews and testimonials online. The supplement has over 2,300 positive reviews on alone, which is something we can’t ignore.
