Erectile dysfunction torments many men, and while the roots of the problem are often psychological rather than physical, there are many cases where physical issues get in the way of healthy sexual function. Physical causes can include high blood pressure, high cholesterol, and diabetes, while psychological problems include stress, anxiety, and depression.

While medications can help, many individuals opt for natural solutions to treat erectile dysfunction before committing to side-effect-prone medical pharmaceuticals.

One of the most effective natural methods used to treat erectile dysfunction is nitric oxide supplements. By increasing nitric oxide levels, blood flow all around the body and into the penis is increased, reducing the chance of erectile dysfunction.

This review discusses the top 9 nitric oxide supplements for ED. Many of these supplements include the potent nitric oxide-booster beetroot. Due to its high nitrate content, beetroot powder is one of the best natural supplements for increasing nitric oxide production. ED’s best nitric oxide supplement is HeartBeets, based on beet extract and 12 additional ingredients that help increase blood flow.

Along with taking one of the recommended nitric oxide supplements, there are lifestyle changes that can help mitigate ED. These include:

• losing weight (if you’re overweight)
• eating healthy (more fruits and vegetables, less processed foods)
• exercise daily (including strength training)
• reduce stress and anxiety (for support, see ADAA)
• quit smoking
• reduce alcohol intake

Combining these lifestyle changes with taking nitric oxide supplements like HeartBeets can be a safe, natural, and effective way to treat erectile dysfunction.

Blood Flow and Erectile Dysfunction

Blood flow plays a crucial role in achieving and maintaining an erection. When a man becomes sexually aroused, the brain sends signals to the penis, triggering the relaxation of smooth muscles in the blood vessels. This relaxation allows for increased blood flow into the penis, specifically into two spongy chambers called the corpora cavernosa. As these chambers fill with blood, they expand, causing the penis to become erect and firm.

Erectile dysfunction (ED) occurs when there are issues with this blood flow process. Various factors can contribute to reduced blood flow to the penis, leading to ED. These include cardiovascular problems, such as atherosclerosis (hardening of the arteries), high blood pressure, and high cholesterol. Other conditions like diabetes, obesity, and smoking can also damage blood vessels and impair circulation. Additionally, certain medications, hormonal imbalances, and neurological disorders can affect the body’s ability to regulate blood flow to the penis.

When blood flow to the penis is compromised, it becomes difficult to achieve or maintain an erection firm enough for sexual activity. This is why many treatments for ED focus on improving blood flow. Treatments like lifestyle changes, exercise, and managing underlying health conditions aim to improve overall cardiovascular health and blood flow throughout the body, including to the penis. Medications like sildenafil (Viagra) and tadalafil (Cialis) work by enhancing the effects of nitric oxide, a natural chemical in the body that relaxes blood vessels and increases blood flow to the penis. As we’ll explore, supplements can also increase nitric oxide naturally.

Nitric Oxide: What is it? And What Does it do?

Nitric oxide (NO) is a crucial signaling molecule in the human body, playing a vital role in regulating blood flow. The inner lining of blood vessels produces this colorless gas called the endothelium.

When released, nitric oxide causes the smooth muscles surrounding blood vessels to relax, leading to vasodilation – the widening of blood vessels. This process increases blood flow throughout the body, improving circulation and oxygen delivery to tissues and organs.

Nitric oxide’s effects on blood flow have significant implications for cardiovascular health. It helps maintain healthy blood pressure, reduces the risk of blood clot formation, and supports overall heart function. Additionally, NO contributes to exercise performance by enhancing muscle blood flow during physical activity.

How Does Increasing Nitric Oxide Levels Treat Erectile Dysfunction?

Nitric oxide can help to treat erectile dysfunction by promoting blood flow to the penis. As noted, this naturally occurring molecule acts as a vasodilator, relaxing and widening blood vessels throughout the body, including those in the genital area.

When sexual stimulation occurs, nitric oxide is released in the penis, triggering a series of chemical reactions. These reactions increase the production of cyclic guanosine monophosphate, a compound that relaxes smooth muscles in the blood vessels. As a result, more blood can flow into the penis, facilitating and maintaining an erection.

By increasing nitric oxide levels, men with erectile dysfunction can experience improved blood flow to the penis, leading to firmer and more sustained erections. This can be achieved through various methods, including dietary changes, exercise, medications, and supplements that enhance nitric oxide production or prolong its effects on the body.

The Best Supplements and Vitamins for Increasing Nitric Oxide Levels

Here is a table of natural vitamins, minerals, and plant extracts known to increase nitric oxide production in the body. Brief explanations of how each works and dosage recommendations based on science are included.

Table 1: Top Tier Nitric Oxide Boosters

Booster	How it Works	Recommended Intake
Beetroot (or beetroot extract)	The high nitrate content rapidly converts to nitric oxide, improving blood flow, reducing blood pressure, and enhancing exercise performance. It can increase NO levels by up to 21% within 45 minutes.	at least 300-500 mg of beetroot extract or 2g of beets powder
Vitamin C	It enhances nitric oxide synthase (NOS) activity, stabilizes NO molecules, and improves the bioavailability of other NO-boosting compounds.	200-600 mg daily
Folate (Vitamin B9)	It supports the proper function of nitric oxide synthase, reduces homocysteine levels, and enhances the bioavailability of BH4 (a crucial cofactor for NOS enzymes).	400-2500 mcg daily
Garlic	It contains allicin and sulfur compounds that stimulate NO production, activate nitric oxide synthase, and maintain NO levels in the blood.	150-1,200 mg of garlic extract daily
Magnesium	It acts as a cofactor for enzymes involved in NO synthesis, activates nitric oxide synthase, and supports overall blood vessel health.	200-400 mg daily
Green Tea Extract	It protects NO from degradation, enhances NOS activity, and improves endothelial function.	250 mg of green tea extract daily

Table 2: Additional Nitric Oxide Supporters

Supporter	How it Supports NO Function
Vitamin E	Protects NO from oxidative stress, works synergistically with Vitamin C
Vitamin D	Activates nitric oxide synthase supports cardiovascular health
Niacin (Vitamin B3)	Supports NO production and improves blood flow by dilating blood vessels
Cocoa Flavanols	Improve NO bioavailability and stimulate its production
Pomegranate	Protects NO from oxidative stress, enhances its biological actions
Pine Bark Extract (Pycnogenol)	Stimulates NO production, supports healthy blood vessel function
Ginseng	Increases NO production through various mechanisms, including NOS activation
Omega-3 Fatty Acids	Enhance NO production and improve its bioavailability
Resveratrol	Activates nitric oxide synthase and increases NO production
L-Arginine and L-Citrulline	Serve as precursors to nitric oxide (L-Citrulline often more effective due to better absorption)
Quercetin	It enhances NO production and helps maintain its levels in the body

Remember, while these substances can help increase nitric oxide production, it’s always best to consult with a healthcare professional before starting any new supplement regimen, especially if you have pre-existing health conditions or are taking medications.
