Listen, guy. We’re not trying to trigger PTSD from our organic chemistry days, but if you’re a dude concerned about blood flow downstairs — and therefore, arousal quality — you can’t even begin to have the conversation about ED without talking about nitric oxide.
And we probably don’t need to tell you that. After all, googling natural treatments for ED has probably brought nitric oxide supplements to your attention.
Available over-the-counter, many nitric oxide supplements claim to boost blood flow, giving you stronger arousal and better physical performance and athletic performance (you remember the ad screaming at you through an incognito browser, we’re sure).
Do they work? Are they your key to better intercourse? It’s complicated. Below, we’ve explained:
-
What nitric oxide is and how it’s necessary for your body
-
The science behind nitric oxide supplements
-
Whether or not they’re worth using for better physical health and arousal
Oh, and we’ve also shared a few other, evidence-based treatment options that you may want to consider if you suffer from ED.
What Does Nitric Oxide Do?
First things first: nitric oxide isn’t some BS supplement ingredient from a rainforest frog’s privates — it’s real science.
Nitric oxide is a gas naturally produced inside your body that works as a type of signaling molecule for your cells and organs. In fact, nitric oxide plays a role in almost every cellular and organ function in your body as it’s converted to nitrate.
Its key role, however, is to regulate the tone and blood flow of your vascular system — the complex network of blood vessels that transports oxygen and nutrient-rich blood to your organs and is charged with removing waste products.
Nitric oxide is also known as a vasodilator. It’s a chemical that increases blood flow and promotes lower blood pressure through its effects on soluble guanylate cyclase (sGC), a type of enzyme found in the smooth muscle of your blood vessels.
When soluble guanylate cyclase is active, your blood vessels can increase in size, allowing for better blood flow to certain parts of your body.
That’s a lot of jargon to explain that nitric oxide helps blood more easily move to where it’s needed. And that’s really important when where you want the blood to go is into your member for arousal.
Does Nitric Oxide Help in the Bedroom?
Nitric oxide, it turns out, is clutch when you’re trying to get hard. Research has found that nitric oxide plays a key role in facilitating arousal by relaxing the vascular muscle that supplies your member with blood when you’re aroused.
This increase in blood vessel diameter and blood flow is what allows your member to get firm while you’re getting intimate. So yeah, that’s really, really important.
Because nitric oxide plays such a major role in healthy arousal, medical conditions that reduce your production of nitric oxide can potentially contribute to ED.
And the risks don’t stop at efficiency. Low nitric oxide levels may also contribute to a higher risk of common heart health issues, such as cardiovascular disease.
If you’re in this situation, you may be wondering how to pump some of this priming gas into your member. That’s more complicated than it may seem.
What Are Nitric Oxide Supplements?
Nitric oxide supplements are exactly what they sound like — supplements that claim to increase levels of nitric oxide within your body.
They’re available over-the-counter as pre-workout style powdered drinks, beetroot extracts or capsules, and can be purchased from drug stores, health food stores and, yes, even online.
There’s a bit of a catch to these products, though, and it has to do with what’s actually inside these supplements.
Most of the time, dietary supplements have the same active ingredient as their name suggests. For example, creatine supplements contain creatine, and protein supplements contain different types of protein.
Nitric oxide supplements, on the other hand, contain active ingredients that are used within your body to supposedly increase its own nitric oxide production. More specifically, most nitric oxide boosters contain the active ingredients L-arginine and L-citrulline. These amino acids act as biological “building blocks” for nitric oxide within your body. The idea behind these supplements is that giving your body the nutrients it needs to produce its own nitric oxide will increase nitric oxide levels.
The Research Supporting Nitric Oxide Supplements
Some research backs up this theory. With lots of dietary supplements, many of the studies used to support the idea that nitric oxide precursors boost nitric oxide production are animal research. For example, one study published in 2014 in the journal Biochemical and Biophysical Research Communications found that oral use of the amino acids L-arginine and L-citrulline — the two amino acids typically used in nitric oxide supplements — increased nitric oxide levels in rats and rabbits.
But that’s not to say there aren’t some promising studies involving people on whether supplements can boost nitric oxide or not. Prelox, a combination of L-arginine aspartate and Pycnogenol (another popular natural supplement otherwise known as maritime pine), was shown to support nitric oxide production in clinical trials. Notably, a study looking at L-arginine and L-citrulline levels in men found that men with severe ED with an arteriogenic etiology had lower levels of these two amino acids, indicating a possible nitric oxide synthesis related explanation.
Improved your time in the bedroom was also reported in nine patients who took L-arginine supplements to boost their nitric oxide levels. And finally, a three-month trial using Pycnogenol to increase L-arginine and NO levels saw just over 92 percent of men with ED achieve normal arousal.
You might be thinking, “Hey, all this research on humans looks good! 92 percent is a great number for arousal!” And you’re not wrong.
But many of these studies were on the smaller side. So while they’re promising, it doesn’t necessarily mean that supplements for nitric oxide work the same way in humans. A review published in the journal Sports Medicine found that nitric oxide supplements do appear to offer exercise-related benefits, including increased exercise performance. It’s worth noting that these effects were observed in people with low to moderate prior training — in more highly trained people, nitric oxide supplements didn’t show any effects.
Do Nitric Oxide Supplements Help With ED?
Dietary supplements don’t need to have the same proof about their claims that medications need to have. And as such, there aren’t any nitric oxide supplements that have been approved by the FDA to treat ED, which means your provider probably won’t be raving about how excited they are to recommend them to you.
But these supplements may have some effect on ED. Although nitric oxide supplements shouldn’t be viewed as a treatment for ED, a small amount of research suggests that there may be benefits of nitric oxide for arousal and male intimacy function:
-
An article published in the journal Future Science OA looked at several studies of L-arginine supplements and L-citrulline supplementation, noting that some had shown improvements in hardness scores and other measures of arousal function.
-
A small study also found that use of a dietary supplement containing L-arginine produced improvements in arousal health and function in men with ED.
-
Some research suggests that beetroot and beetroot juice offer a natural and antioxidant-rich source of nitric oxide, which may offer benefits in treating certain health conditions — potentially including ED.
The research we have looks promising, but we need a lot more before anyone can say anything definitive about the efficacy of these supplements.
Nitric Oxide Supplement Side Effects
One of the biggest problems with supplements is that, because the FDA doesn’t have the same grip on them, they can be less predictable (and less safe) than medications.
Nitric oxide supplements could boost nitric oxide in your body, but they may cause unwanted effects when you take them. For nitric oxide, those side effects may include:
-
Increased risk or worsening of heart failure
-
Hypotension, or low blood pressure
-
Pulmonary vasospasm
If you experience dizziness, chest pain or other issues when taking nitric oxide, seek immediate medical attention.
Alternatives to Nitric Oxide for ED
Nitric oxide supplements may work, but if you’re looking for more proven ED treatments, options abound to improve blood flow. Medications approved by the FDA and changes to your lifestyle can do more than supplements in almost all cases. Let’s look at how.
FDA-Approved ED Medications
Currently, the FDA has approved four science-backed oral medications for ED:
-
Sildenafil (the active ingredient in Viagra)
-
Tadalafil (Cialis)
-
Vardenafil (Levitra)
-
Avanafil (Stendra)
These medications belong to a class of drugs called PDE5 inhibitors, which work by preventing the enzyme phosphodiesterase-5 from restricting blood flow to the tissue located inside your member.
They can be taken as-needed 30 to 60 minutes before intercourse, making it easy to deal with ED and improve your performance. The FDA has also approved an injectable medication, alprostadil, for ED, and it has recently authorized a topical gel for ED.
Lifestyle and Habits
You can also reduce your risk of dealing with ED by making healthy changes to your habits and lifestyle. These changes can be particularly important, since ED is often the “canary in the coal mine” for cardiovascular disease.
Several things may help improve your bedroom function and prevent ED. For example:
-
Exercising regularly
-
Maintaining a healthy weight
-
Limiting your alcohol intake
-
Quitting smoking
-
Avoiding illicit drugs
This guide to naturally protecting your arousal goes into more detail about these techniques and other approaches that you can use to improve your function naturally.
Nitric Oxide Supplements: Should You Use Them?
Nitric oxide is an important signaling molecule that your body uses for a wide variety of different functions, including supplying blood to your member when you’re aroused. It’s certainly an essential biological ingredient. But supplementing it isn’t a plan without risks.
Consider the following when weighing your choices:
-
Research on nitric oxide supplements and ED is limited, but some studies suggest that the L-arginine and L-citrulline found in nitric oxide supplements help to treat ED.
-
Using a nitric oxide supplement may generally help to strengthen your arousal and improve your intimacy function.
-
However, you’ll notice the biggest improvements from evidence-based medications like sildenafil (Viagra), tadalafil (Cialis) and avanafil (Stendra).
-
Lifestyle changes can also improve your cardiovascular health and well being.
