Benefits, Dosage, and Side Effects

Here's the benefits, dosage and side effects of nitric oxide supplements.


Did you know that nitric oxide is a powerful molecule that has a crucial role in regulating blood flow and cognitive function? In fact, it plays a part in maintaining a healthy immune system too.

But that's not all - athletes and fitness enthusiasts have started using nitric oxide supplements to elevate their workouts. This is because nitric oxide can help improve muscle pumps, endurance, erectile dysfunction symptoms, and even reduce recovery time after intense exercise.


Discovering the perfect dosage of nitric oxide production is a topic that has been continuously debated among experts. While some advise consuming a minimal dose (10-20 mg) pre-workout, others believe that a larger quantity (50-100 mg) consumed daily provides better results.

The key to determining your ideal intake is to experiment, but it should always be done under moderation and following the directions of product labels.

Side Effects

When taking nitric oxide supplements, just like all other supplements, it's important to be aware of the potential downsides. One of the most common side effects is headaches, which may occur due to the increased blood flow that nitric oxide triggers.

Nausea, vomiting, and diarrhea are also possible side effects. Additionally, individuals should take caution as some research has shown that nitric oxide supplements may lead to liver damage.

Nitric Oxide Supplements FAQs

Are nitric oxide supplements safe?

Nitric oxide related supplements are considered safe when taken within the recommended dosage. They can be beneficial in boosting energy, and reducing fatigue and muscle soreness during exercise.

It's a naturally occurring molecule produced by the body that helps dilate blood vessels, increase blood flow, and reduce inflammation. It also plays a role in cell signaling processes throughout the body.

Is L-arginine and nitric oxide the same?

L-arginine and nitric oxide are not the same. While L-arginine is an amino acid that serves as a precursor to nitric oxide, nitric oxide itself is a powerful molecule that helps to dilate blood vessels and promote healthy blood flow.

Thanks to the intricate biochemical processes in our bodies, enzymes work to convert L-arginine into nitric oxide. For those looking to boost their nitric oxide levels, other nitric oxide supplements containing L-arginine or other amino acids, aid in its production and can be a helpful addition to your regimen.

When should I take nitric oxide?

You can boost your blood flow and get the much needed extra edge before hitting the gym. Or jumpstart your day by taking nitric oxide in the morning and feel a wave of renewed energy.

The best part? Nitric oxide can be taken at any time of day, with or without food. Experiment and find the method that works best for you, but if you’re looking to maximize your workout, take it 30-60 minutes before pumping iron.

What is the best way to get nitric oxide?

Boosting your nitric oxide levels is crucial for maintaining a healthy cardiovascular system. While exercises that increase your heart rate and consuming antioxidant-rich fruits and veggies are some of the best ways to achieve this, taking supplements like beetroot juice or arginine can also do wonders.

Can too much nitric oxide be harmful?

Nitric oxide, while important for various bodily functions, can cause serious harm when present in excessive amounts.

In fact, an overabundance of nitric oxide can trigger oxidative stress, which not only leads to cell death but can also stunt mitochondrial respiration, which is essential for maintaining energy levels in cells. So if you want to avoid feeling lethargic and fatigued, it's crucial to keep your nitric oxide levels in check.

What are the symptoms of low nitric oxide?

Low levels of nitric oxide can lead to some unpleasant symptoms, such as headaches, fatigue, and shortness of breath. Even more seriously, it can increase your risk for heart disease and other health issues.

But don't worry - there are natural ways to boost your nitric oxide levels. From getting your sweat on with regular exercise, to fueling your body with whole foods and reducing stress levels, it's easy to give your body the support it needs for optimal health.

What foods are highest in nitric oxide?

Next time you're grocery shopping, add some vibrant greens like spinach and lettuce, as well as crunchy veggies such as beets, celery, and carrots, to your cart. These nitric oxide-rich foods offer a whole host of benefits for your body, from improving blood flow and lowering blood pressure to protecting your arteries and preventing heart disease.

What drinks are high in nitric oxide?

Beet juice, green tea, and red wine are nitric oxide boosters that are packed with high levels of nitric oxide. These drinks also boast impressive anti-aging properties. Beet juice reigns supreme over the other two, due to its sky-high nitric oxide levels.

Does beet juice increase nitric oxide?

Beet juice can help regulate blood pressure, improve blood flow, and boost immunity. Beet juice is packed with nitrates - nutrients that the body easily converts into nitric oxide. According to studies, drinking beet juice regularly can significantly increase nitric oxide levels and bring about a host of health benefits.
