Erectile dysfunction is a serious problem for more than 53.4% of men between 30 and 80 years (1). It is such a widespread health issue that affects around 10% of men per decade, for example, 60% of men in their 60s, 70% in their 70s, 80% in their 80s, and so on (2).

What most people don’t realize is that a vitamin B12 shortage could be the source of the problem. Instead, they are blaming it on other diseases like diabetes or incontinence. That’s why you need to know the right vitamin B12 dosage for erectile dysfunction.

Here we will cover all you need to know about vitamin B12 for erections, including effect, dosage, and impact.


What Do Vitamin B12 Doses Have to Do With Erectile Dysfunction?

Researchers estimate that around 3.2% of all adults over 50 have a B12 deficiency, while 20% are at a borderline deficiency (3).

This vitamin plays a predominant role in many bodily functions, including nerves, DNA, red blood cell formulation, etc.

Vitamin B12 deficiency and erectile dysfunction go way back. Even in the 60s, researchers noticed a drastic impact of B12 on sperm count. In fact, this vitamin has a crucial role to play in sperm quality and male infertility (4).

If a man’s body doesn’t produce or get enough vitamin B12, he can experience erectile dysfunction. The reason for that is relatively simple. Due to the insufficient doses, the effect of the deficiency can damage the nerves in the penis. That’s why keeping or achieving an erection becomes an impossible task.

Another problem is the excessive vitamin B12 doses. If a person takes more B12 than the recommended daily amount, they can be at risk of developing mild erectile dysfunction. The moment the B12 levels in the body exceed normal levels, it will trigger the body’s defense mechanism (5).

As a reaction to the trigger, the protection mechanism will start to absorb even more B12, resulting in numerous erectile problems. That’s why scientists believe there is a strong connection between B12 and erectile dysfunction.

What’s The Right Vitamin B12 Dosage for Erectile Dysfunction?

For most people, the suggested daily intake for B12 is 2.4 mcg (6).

But, depending on the problem, lifestyle, and age, the doses can vary. Keep in mind that you are taking all of the B12 from foods or supplements. Here is how you can tailor the doses to your needs.

For Individuals Over the Age of 50

Adults are vulnerable to B12 deficiency and erectile dysfunction. In fact, 62% over 65 years lack B12 in their system (7, 8).

The older we get, the less intrinsic factor and stomach acid the body creates, which affects the B12 absorption rate. Therefore, for the older generation, it’s best to take fortified foods and supplements to replenish the body.

Adding 500 mcg of B12 can be efficient. For more serious erectile dysfunction, 1,000 mcg could come in handy (9).

For Individuals Under the Age of 50

The ideal dosage is 2.4 mcg. But, most people get this amount through the food they consume on a day to day basis.

Eggs, beef, and tuna are an excellent B12 source. However, if you have any underlying health issue that meddles with the B12 absorption rate, it could be a good idea to take a supplement.

Individuals on a Vegetarian Diet

According to multiple surveys, 86.5% of grown-ups on a vegetarian diet regularly lack a sufficient amount of vitamin B12 in their system (10).

If you are consuming mainly plant-based meals, you need to make sure you are getting vitamin B12 elsewhere.

Since 2.4 mcg is tricky to get with a vegetable diet, it’s best to add a supplement. It could help use six mcg of B12 daily to replenish the vitamin supply (11).

For Individuals Who Lack Energy

Stamina and energy are critical factors for better sex life. The higher the energy, the easier it is to maintain longer intercourse. But, when a person doesn’t have the vigor to do it, it could be due to the lack of B12.

Vitamin B12 can restore the body’s energy. It can be a good idea to take 1 mg of B12 (1,000 mcg) a day for a whole month.

For individuals with serious absorption issues, it could be useful to try B12 injections. Health complications such as Crohn’s disease can have a severe impact on the B12 absorption rate. These injections can bypass the entire digestion process and quickly get to the bloodstream (12).

Vitamin B12 Fact vs. Fiction

There are a lot of speculations about this vitamin. But, it’s crucial to differentiate fact from fiction. Some people believe enough vitamin B12 can reverse infertility. But that’s not true. It can’t treat or reverse serious chronic conditions.

B12 can manage minor health problems you might be experiencing as a result of the deficiency. It can’t cure any blood conditions or neurological issues, either.

Since our body can’t produce it on its own, we have to take it from supplements or food. As a result, it is common for people to have low levels of B12 in their system.


Countless people are dealing with erection difficulties. What many don’t realize is that vitamin B12 can be causing it. There is a strong connection between B12 and erections. That’s why it’s crucial to find the right vitamin B12 dosage for erectile dysfunction.

The guideline we listed here can help you achieve precisely that. Everything you see here is something you can use to get better control of your problem.
