Due to the prevalence of erectile dysfunction, many look for ways to treat it fast. One of the treatment solutions that you may come across in your search is vitamin B12. What can vitamin B12 do for men who cannot get an erection or keep an erection long enough to satisfy their partners? Let us take a look at the roles of vitamin B12 in the human body.

What is vitamin B12?

Among the eight types of B vitamins, vitamin B 12 is the biggest and most complex, structure-wise. It plays a key role in cellular metabolism, DNA synthesis, and production and development of red blood cells, and is associated with a man’s fertility and erectile functions.

With vitamin B12, you can lower your risk of megaloblastic anemia, which is a type of anemia that causes weakness and exhaustion. You can also enjoy better mood and higher energy levels each day, better concentration and cognitive function, and prevent memory loss and immune disorders.

Where can you get vitamin B12?

There is a long list of healthy foods that can give you the vitamin B12 that you need for good health and wellbeing. Below are some examples:


foods rich in vitamin B12

An excellent source of protein, clams are overflowing with vitamin B12, omega-3 fatty acids, and other essential nutrients that promote sexual and reproductive health. They can also help prevent certain types of cancers and improve your skin health.


Low-fat cuts of beef can provide you enough vitamin B12 to boost your erectile health. They are best prepared roasted or grilled to preserve their vitamin B12 content. For every 100 grams of beef, you can get about 6.2 micrograms of vitamin B12.

Lamb liver

With a high concentration of vitamin B12, eating lamb liver can enhance your penile performance. Because it is also rich in vitamin A, vitamin B2, selenium, and copper, it can keep your different vital organs functioning properly, and ward off infections and diseases that can threaten your health.


A widely consumed fish, tuna is filled with different kinds of essential nutrients, including vitamin B12, protein, vitamin A, vitamin B3, phosphorus, and selenium. It can help reduce your odds of developing erectile dysfunction, and keep you from gaining weight and suffering from high cholesterol, high blood, and other complications.


A glass of milk a day can help improve your penis health, thanks to its high levels of vitamin B12. It is also a great source of calcium, so it can strengthen your bones and teeth, prevent osteoporosis and other bone disorders, and facilitate enzyme production and functions.

How much vitamin B12 do you need?

The vitamin B12 concentration that your body requires is dependent on your age. Here are the recommended vitamin B12 amounts for the different age groups:

  • Children 8 years old and below – 0.4 micrograms to 1.2 micrograms
  • 9 years old to 13 years old – 1.8 micrograms
  • 14 years old to 18 years old – 2.4 micrograms
  • 19 years old and above – 2.6 micrograms

What happens if you are not getting enough vitamin B12?

Lack of vitamin B12 in the body can lead to vitamin B12 deficiency, which is a problem that can bring about several symptoms and complications.

Usually, if your body has a shortage of vitamin B12, you are likely to experience warning signs, such as weight loss, appetite loss, constipation, weakness, and exhaustion. In some cases, people who have low vitamin B12 levels may also suffer from poor memory, soreness of the tongue or mouth, depression, or difficulty balancing.

If not dealt with right away, vitamin B12 deficiency can lead to more serious health issues that include:

Low energy levels

Because of low energy, carrying out even the simplest tasks can become difficult. If you are an athlete, you will notice a drastic decline on your performance, and a longer time needed for recovery.

Heart disease

The chances of suffering a stroke or a heart attack increase if your vitamin B12 levels are low, as your body’s red blood cell production is impaired.

Several studies have found that there is a link that exists between vitamin B12 and erectile dysfunction. According to them, if there is a deficiency in vitamin B12, there is an increased risk of not only erectile dysfunction but infertility as well.

Two of the functions of vitamin B12 is facilitating DNA formation and duplication, and promoting the formation of healthy red blood cells. If these are carried out properly, your brain function and cellular metabolism are enhanced, resulting to improved sexual function. Your testicles’ ability to produce enough sperm with good structure, quality, and motility is also improved.

There was also one study that proved that vitamin B12 can stimulate blood circulation and strengthen the nerves in the penis, which can lead to more satisfactory erectile functions and fewer embarrassing moments in the bedroom.

Are there vitamin B12 supplements available?

If you need more vitamin B12 than the foods listed above can give, you can look into vitamin B12 supplements. Sometimes, the human body has trouble absorbing vitamin B12 that comes from foods, so supplements are a good alternative.

Almost all the over-the-counter multivitamin products that are available these days contain vitamin B12, so it should not be difficult to find one to use for your needs. There are also supplements that contain only vitamin B12, or with other B vitamins and folic acid too, if that is what you prefer.

Supplements that require a doctor’s prescription also exist, and they come in the form of a vitamin B12 shot or a vitamin B12 nasal gel. These prescription medications are usually given as a treatment for vitamin B12 deficiency patients.
