Improving your erections boils down to two key things.

Can you guess what they are?

Yes, I’m talking about your libido and testosterone levels.

If your testosterone and libido don’t work properly, it’s a recipe for having weak erections. In fact, low testosterone and erectile dysfunction are very much interlinked.

So when choosing vitamins for erectile strength, you should look for the ones that also boost testosterone and sex drive.

These are the two secrets ‘ingredients’ for having erections as strong as an 18-year old teen.

In this article, I’ll explain how erections and testosterone are linked. I’ll also cover the best nutrients, herbs, and vitamins for erectile strength. Explaining how each works, along with their optimal dosage for boosting your erections, libido, and testosterone.

Okay, we admit it, ashwagandha and fenugreek aren’t vitamins, but they deserve to be on the list nonetheless as they allow the other vitamins and minerals to work effectively.

Vitamins for erectile strength, which are the best? Here’s a quick summary for you;

  1. Vitamin D
  2. Vitamin B6
  3. Zinc
  4. Vitamin K2
  5. Ashwagandha
  6. Fenugreek

How Low Testosterone Causes Weak Erections

There’s a definite link between testosterone and erections.

Studies have shown that low testosterone could be one of the causes of erectile dysfunction.

Now, whether it’s a direct or indirect cause, is up to debate. Science is still not clear on that.

But one thing is very much clear – low T-levels lead to obesity, weak libido, cardiovascular diseases, and other health problems. All of which can cause weak erections. [1]

So the key to remember is, that while testosterone might not be a direct cause of weak erections, it can be an indirect one. Causing other health problems that then lead to ED. [2, 3]

Did you know? Over 40% of men suffer from some type of ED by the time they are 40. This number goes way up to 70% in men over 70 years old. [4]

Boosting Your Testosterone Naturally

Okay, since we know that having high T is crucial for healthy erections. Let’s look at the ways you could improve your T-levels naturally.

Here are the 5 best ways to boost your testosterone;

  1. Exercise – science has shown that regular exercise, especially weight training, leads to increased testosterone levels in men. [5, 6, 7]
  2. Eating a Nutrient-Dense Diet – It’s no surprise that what you eat governs how you’ll look and feel. If you want to keep strong erections, you need to eat libido-friendly foods. Including oysters, nuts, beef, and herbs such as Asian Ginseng. [10, 11, 12]
  3. Sunlight Vitamin D is one of the most important vitamins for keeping your erections strong and testosterone levels high. And the sun is the best source of vitamin D. If you can’t get at least half an hour of direct sunlight every day, consider taking a vitamin D supplement. [8, 9]
  4. Keeping Stress Levels Low Stress and hormones aren’t very good friends. In fact, when your stress levels are high, you start losing muscle mass, T-levels start crashing down, and your erections become flabby and weak. If you can’t seem to keep stress under control no matter what, consider taking adaptogenic herbs such as Ashwagandha, which is shown to reduce cortisol by up to 30%. [13, 14, 15, 16]
  5. Natural Supplements and vitamins – Supplements are one of the best ways of obtaining key nutrients that make your erections strong. I’ll cover them in more detail below – sit tight.

Best Herbs, Nutrients & Vitamins For Erectile Strength

Vitamin D

Vitamin D has long been touted as one of the most important nutrients for humans. It’s linked with brain health, heart function, and testosterone production. Not only that, but vitamin D improves erections too, via the mechanism of increasing libido. [17]

In fact, a deficiency in vitamin D leads to a whole host of health problems. Including weak erections, low libido, crashing testosterone, and poor cognitive function.

It’s very hard to get vitamin D from diet alone. Only a few foods contain it in sufficient quantities. These include egg yolks, fatty salmon, and fortified cereals.

However, you’d need to eat these foods every day to reap the benefits of vitamin D. Which is not something you might want to do, if you’re looking to lose fat.

This leaves us with two other options – sunshine and supplements. And since most people don’t go in the sun often, vitamin D supplementation becomes crucial.

If there’s one vitamin that tops every other when it comes to boosting erections, it’s vitamin D. Studies show it helps improve blood flow to the penis, along with increasing T levels.

Vitamin B6

Vitamin B6, or Pyridoxine, is an important nutrient in keeping your erections strong.

When you’re looking to boost your erectile strength, there are much safer alternatives to viagra pills and other drugs.

Vitamins such as B6 reduce the production of estrogen (female sex hormone) in your body, thus leading to increased testosterone qualities – such as improved erections.

And the best of all, it’s a natural nutrient which your body needs to function optimally. Unlike with Viagra, there are no side effects from taking a vitamin B6 – only positives.

Regular intake of this vitamin doesn’t just support your erections, it also helps you keep a healthy liver, eyes, skin, and testicle function.

There are many sources of Vitamin B6 in your diet. Such as tuna and sunflower seeds. However, getting enough of tends to be an issue.

Studies show that sub-optimal levels of B6 lead to a reduced testosterone production. Which then leads to low libido & erectile problems. [18]

So if you’re looking to keep your erections strong, make sure to add vitamin B6 to your supplement stack.

Supplementing with vitamin B6 is shown to have positive effects on your testosterone, libido, and erectile strength.


Zinc might not be a vitamin, but it’s one of the most important nutrients for erectile strength hands down.

With the ability to improve testosterone, strengthen the immune system, and boost your erections, it’s a must for anyone who’s looking to improve their health and masculinity. [20]

Since you lose zinc through sweat, it’s very common for men to become deficient in this mineral. In fact, a lack of zinc is one of the more common nutrient deficiencies among people. [19]

So considering zinc’s importance for health, taking a Zn supplement is a good idea. Just make sure not to overdo it – 10mg of zinc daily is enough to obtain its key benefits.

Zinc is a mineral that’s involved in many bodily processes. From testosterone production to heart health to keeping your erections strong.

Vitamin K2

Vitamin K2 is yet another nutrient on this list that’s essential for your erectile health. [21]

You see, there are two types of K vitamin: K1, and K2.

Vitamin K2 is the one that’s responsible for improving blood flow to the penis and boosting the effects of vitamin D3. It also plays a role in keeping your T-levels high.

These benefits make vitamin K2 even more important than K1 when it comes to keeping your erections strong. [22, 23]

However, while we get plenty of K1 through our diet, getting K2 is a little more tricky.

There are some foods which contain it, such as butter, egg yolks, and fatty meat. However, these might not be the healthiest choice.

That’s where K2 supplements come in.

By getting vitamin K2 in a capsule form, you ensure all of its benefits without having to eat excess calories.

K2 is one of the most important vitamins for erectile strength. It improves blood flow to the penis, synergizes with vitamin D, and boosts T production.


Now, Ashwagandha isn’t a vitamin, but it’s a herb that’s been used to improve libido & erections for thousands of years. And that’s why it’s on the list.

Ashwagandha’s active components are called Withanolides. They are responsible for many of ashwagandha’s benefits. Including [24, 25, 26, 27];

  • Improves erections
  • Calms the mind (reducing stress & anxiety)
  • Enhances libido
  • Reduces cortisol (a muscle-wasting stress hormone)
  • Increases lifespan
  • Improves testosterone production

Ashwagandha’s potency in boosting erections makes it even stronger than some of the vitamins for erectile strength on this list.

Ashwagandha promotes healthy erections by reducing stress hormones, boosting libido, and increasing testosterone levels. It’s also a potent anti-anxiety agent.


Just like ashwagandha, Fenugreek is an ancient herb used for ramping up libido and sex drive. [30]

According to studies, Fenugreek even increases the amount of free testosterone in your body. [29]

How does it do it?

Well, Fenugreek acts as an aromatase inhibitor. This means it negates the effects of aromatase, a hormone that converts testosterone to estrogen.

So by inhibiting aromatase activity, Fenugreek effectively improves the level of free T in your blood.

This ancient herb also reduces inflammation, supports the immune system, and helps reduce blood sugar. These benefits then lead to improved blood flow, and ultimately – stronger erections. [28]

Fenugreek improves testosterone, blood flow, and reduces inflammation – all of which are key to erectile health.


When choosing vitamins for erectile strength, you should ask yourself two important questions:

“Do these vitamins boost testosterone” and “Will they increase my libido?”

If the answer is yes to both of these questions, then these vitamins are qualified to be called erectile boosters. This is one of the easiest methods to tell if a supplement will give you the results you’re after.

This is because testosterone and libido are key factors in making your erections strong. It’s been proven that low T leads to low libido, which then leads to weak erections, loss of sex drive, and loss of interest in women.

Just to quickly recap, the best nutrients & vitamins for erectile strength are;

  1. Vitamin D
  2. Vitamin B6
  3. Zinc
  4. Vitamin K2
  5. Ashwagandha
  6. Fenugreek
