Enhancing Gym Performance: Nitric Oxide Supplements Guide 2024

Nitric oxide supplements have gained popularity among the fitness community for their potential to improve athletic performance and reduce recovery time.
It’s a gas that is naturally produced in the body and acts as a vasodilator, relaxing and widening blood vessels to improve blood flow and lower blood pressure. This increased blood flow can enhance exercise performance by delivering more oxygen and nutrients to the muscles, allowing an athlete to work out harder for longer. Nitric oxide supplements often contain amino acids such as L-arginine and L-citrulline, which can be converted into nitric oxide in the body.
This article is more on the range of “gym bro advice”, then an actual scientific meta analysis.

Short Answer

Nitric Oxide’s effect for me was similar to natural pre-workout supplements like L-Arginine and L-Citrulline. It reduces blood pressure and improves “the pump”. I personally like it a lot for a prolonged “110% saturday workout”.
Many parts of usual pre-workout supplements are converted into nitric oxide in the body.

Very dumbed down: When you take L-Arginine, your body converts it into nitric oxide.
L-Arginine’s bioavailability is lower, why a direct nitric oxide supplement may be more effective.
My opinion in short: very useful as a pre-workout. I found it to be a lot more effective than L-Arginine or L-Citrulline.

The best nitric oxide supplements are won from natural ingredients like cranberry seed or grape seed blends.
In my opinion, the best nitric oxide supplement is by Pure Encapsulations. It’s quite expensive, but it’s one capsule before specific workouts and I think they actually produce the highest quality supplements on the market. I also take Macula Support (Carotenoids) from them. I do not take Nitric Oxide for every single workout.

Key Takeaways:

  • taking nitric oxide supplements can enhance athletic performance by increasing blood flow to the muscle
  • Nitric Oxide prevents oxidative stress on the body
  • Nitric oxide is a naturally occurring gas produced in the body that acts as a vasodilator
  • Amino acids like L-arginine and L-citrulline can be converted into nitric oxide and are commonly found in nitric oxide supplements

I know – boring – but as always: check out my disclaimers at the bottom. I am not a healthcare professional and just reflect my own experience and understanding in this article.

Natural Nitrate Sources:

cranberries are the base for nitric oxide supplements

  • Beetroot
  • Cranberries
  • Grapes
  • Spinach and other dark, leafy greens

It’s actually amazing how many incredible benefits cranberries bring. From high iodine, high in citrates, high in vitamin C and so on. Impressive!

Why is it interesting?

As explained later in the article, Nitric Oxide supplements seem to have a range of beneficial effects on the body, mainly linked to decreasing postprandial oxidative stress, increasing blood flow in the muscle and potentially beneficial treatment support for certain illnesses (like for example COVID-19).

Nitric Oxide may actually become your standard pre-workout, if you (like me) do not want to have a classic booster with tons of caffeine and sugar.
I want a smooth pre-workout effect that is overall beneficial, which I do not see in classic boosters.

What is Nitric Oxide exactly?

Nitric oxide is a naturally occurring gas that is produced in the body. It acts as a vasodilator, relaxing and widening blood vessels to improve blood flow and lower blood pressure. Nitric oxide is produced in essentially every cell in the body, and compounds that can be converted into nitric oxide are commonly found in pre-workout supplements. These compounds, such as L-arginine and L-citrulline, help increase nitric oxide production, which can improve athletic performance and overall health.

To understand the role of nitric oxide, it is important to recognize its impact on blood vessels and blood flow. When produced, nitric oxide acts on the smooth muscles surrounding blood vessels, causing them to relax and widen. This widening effect, known as vasodilation, allows for improved circulation and enhanced delivery of oxygen and nutrients to various parts of the body. Additionally, nitric oxide helps regulate blood pressure by maintaining the flexibility of blood vessel walls.

Nitric oxide production occurs through a series of enzymatic reactions within the body. A key enzyme involved in this process is nitric oxide synthase (NOS). This enzyme facilitates the conversion of L-arginine, an amino acid commonly found in protein-rich foods (or in your local supplement store), into nitric oxide. Another compound, L-citrulline, can also be converted into nitric oxide and is often included in nitric oxide supplements.

The production of nitric oxide is not limited to a specific organ or tissue; rather, it occurs in almost every cell. This widespread synthesis highlights the importance of nitric oxide in various physiological functions, including cardiovascular health, immune response, and neural communication.

Nitric Oxide Production in the Body

To better understand the production of nitric oxide in the body, let’s take a closer look at the enzymatic reactions involved:

Enzyme Reaction Result
Nitric Oxide Synthase (NOS) Converts L-Arginine into nitric oxide Nitric oxide gas is produced
Other enzymes Convert nitric oxide into various bioactive compounds Regulation of different physiological processes

It’s important to note that nitric oxide production can be influenced by dietary factors. Certain foods, such as leafy greens and beets, contain nitrates that can be converted into nitric oxide in the body. Additionally, regular exercise has been shown to stimulate nitric oxide production, further emphasizing the role of physical activity in overall health and well-being.

How Does A Nitric Oxide Supplement Work?

Nitric oxide supplements essentially shortcut the body’s conversion from L-Arginine and L-Citrulline into NO. Most of the L-Arginine seems to be lost on the way to the gut and is not efficiently taken up. This is why many people take L-Citrulline, because it’s the next stage of conversion and is a precursor for L-Arginine. Well, Nitric Oxide is a precursor of L-Citrulline. It’s basically is the base substance that provides the actual desired effect of lowering blood pressure for the workout.
The supplements work by providing the body with specific “base” compounds that can be converted into gas-form nitric oxide.
When consumed as part of a pre-workout supplement, these amino acids can help increase nitric oxide production in the body. Nitric oxide acts as a powerful vasodilator, relaxing and widening blood vessels to improve blood flow and oxygen delivery to the muscles. This enhanced blood flow allows for increased nutrient uptake and oxygen supply to the working muscles, resulting in improved endurance and reduced muscle fatigue.

Amino acids play a crucial role in the synthesis of nitric oxide. L-arginine, for example, serves as a precursor to nitric oxide production, while L-citrulline helps to recycle L-arginine within the body for sustained nitric oxide synthesis. By providing the body with these amino acids, nitric oxide supplements support and optimize the body’s natural ability to produce nitric oxide, resulting in increased blood flow and improved exercise performance.

Here is a table summarizing the key mechanisms by which nitric oxide supplements work:

Key Mechanisms How Nitric Oxide Supplements Support
Increased Nitric Oxide Production Provide the body with amino acids like L-arginine and L-citrulline, which can be converted into nitric oxide
Improved Blood Flow Act as vasodilators, relaxing and widening blood vessels for enhanced circulation
Enhanced Nutrient Delivery Optimize the delivery of oxygen and nutrients to the muscles for improved performance
Reduced Muscle Fatigue Support the removal of metabolic waste products from the muscles for prolonged endurance

By leveraging the power of internal production of NO and increased blood flow, nitric oxide supplements provide athletes and fitness enthusiasts with a valuable tool to optimize their performance and achieve their fitness goals.

Does Nitric Oxide Actually Work?

The effectiveness of nitric oxide supplements in increasing it’s production is still a matter of debate. While some studies suggest that these supplements can help enhance exercise performance by increasing nitric oxide synthesis, other research indicates that the benefits may be limited to certain populations, such as moderately trained athletes. Individual responses to nitric oxide supplementation obviously vary, and more research is needed to determine its efficacy.

It’s not clear yet if it makes a big difference on which training level you are. If you are trying to boost your gym performance, this may be worth a try.
Additionally, as always: dosage, timing, and overall quality of the supplement play a role in its effectiveness.

Nitric Oxide and Athletic Performance

Through increased blood flow a higher amount of oxygen and nutrients to the muscles is allowed. As a result, aerobic capacity is improved, endurance is enhanced, and muscle fatigue is reduced.
Meaning: you can lift heavier, longer and “feeling” into your muscles may become easier through enhanced blood flow.

Research suggests that taking a nitric oxide supplement may be particularly beneficial for moderately trained athletes, as baseline athletic ability and aerobic capacity play significant roles in the potential benefits of nitric oxide. For highly trained individuals, the impact of nitric oxide supplementation may be less pronounced due to their already optimized oxygen utilization and exercise efficiency.

To further understand the effects of nitric oxide on athletic performance, additional studies are needed. These studies can help determine the specific mechanisms and dosage requirements of nitric oxide supplementation in different athletic contexts.

Other Benefits of Nitric Oxide

In addition to its effects on athletic performance, nitric oxide offers several other health benefits.

NO enhances recovery, allowing individuals to bounce back faster after intense workouts.

Nitric oxide also plays a crucial role in promoting cardiovascular health. It may be useful for people with Diabetes, as it’s involved in regulating blood sugar levels. Furthermore, nitric oxide is involved in various physiological processes, including neurotransmission and hormone signaling, which contribute to overall health and well-being.

To summarize, the benefits of nitric oxide extend beyond athletic performance. Its ability to reduce muscle soreness, improve blood flow, and support diabetes management underscores its importance in optimizing health and exercise outcomes.

How Nitric Oxide is Produced in the Body

Nitric oxide production in the body occurs through various mechanisms. One of the key ways is the conversion of amino acids, particularly L-citrulline and L-arginine, into nitric oxide with the assistance of an essential enzyme called nitric oxide synthase. This enzymatic process converts the amino acids into nitric oxide, which then acts as a powerful vasodilator, widening blood vessels and improving blood flow.

In addition to amino acid conversion, nitric oxide can also be produced from sweat nitrates and nitrates derived from dietary sources. These nitrates provide the necessary precursor compounds for NO production within the body.

The endothelial cells that line the inner walls of blood vessels play a crucial role in the production of nitric oxide. They produce and release nitric oxide, allowing it to exert its beneficial effects on blood circulation and overall cardiovascular health.

Supplementing with Nitric Oxide

Nitric oxide supplements provide the necessary compounds to increase nitric oxide production in the body. These supplements do not contain nitric oxide itself, but rather substances like L-arginine and L-citrulline that can be converted into nitric oxide. It is important to note that there is no standardized dosage recommendation for nitric oxide supplementation, but it is generally recommended to take less than 10 grams of these amino acids at one time.

If you prefer a more natural approach, nitric oxide can also be increased through the consumption of nitrate-rich foods. Dark leafy greens and beets are excellent sources of nitrates, which can boost nitric oxide production in the body.

When choosing a nitric oxide supplement, it is crucial to select a high-quality product from a reputable brand. Look for supplements that are independently tested for purity and quality to ensure you are getting the most effective product.
