The Nitric Oxide Matrix: The Core of N.O. Fury
At the heart of Six Star N.O. Fury is its powerful 3,000mg Nitric Oxide Matrix. This proprietary blend is designed to stimulate the body's natural production of nitric oxide (NO), a critical molecule for vasodilation—the expansion of blood vessels. By promoting wider blood vessels, this matrix allows more blood, oxygen, and nutrients to be delivered to working muscles during exercise, which helps to increase endurance, muscle fullness, and vascularity. The key active components within this blend are based on the amino acids L-arginine and L-citrulline.
A Breakdown of the Active Ingredients
- L-Arginine (in various forms): A semi-essential amino acid, L-arginine is a direct precursor to nitric oxide in the body. Six Star N.O. Fury includes several forms of arginine in its matrix, such as L-arginine, L-arginine alpha-ketoglutarate, and L-arginine HCl. These different forms are included to help optimize absorption and deliver a steady supply of this nitric oxide precursor to the body. While L-arginine is essential for producing NO, its bioavailability can be low due to breakdown in the gut.
- L-Citrulline: L-citrulline is an amino acid that plays a vital role in the arginine-nitric oxide pathway. The body can recycle L-citrulline back into L-arginine, making it an effective way to sustain elevated L-arginine and, consequently, nitric oxide levels for a longer duration. Studies show that L-citrulline supplementation can be more effective at increasing plasma arginine levels than supplementing with arginine directly, leading to more sustained nitric oxide production. This ingredient is key to the product's effectiveness for promoting prolonged pumps and endurance.
Understanding the 'Other' Ingredients
In addition to the active nitric oxide blend, N.O. Fury caplets contain several inactive ingredients that serve a variety of purposes, such as binding the ingredients together, providing a coating for easier swallowing, and improving shelf life. These components include:
- Microcrystalline cellulose and croscarmellose sodium: Common fillers and disintegrants that help the caplet break down properly in the digestive system to release the active ingredients.
- Stearic acid and magnesium stearate: Lubricants used to prevent the caplet ingredients from sticking to the manufacturing machinery.
- Coating (polyethylene glycol, talc, titanium dioxide, FD&C red no. 40): A film coating that makes the caplets smoother to swallow and gives them a distinct appearance.
- Crospovidone: Another disintegrant that aids in the caplet's dissolution.
- Silica: An anti-caking agent to prevent the powder from clumping during manufacturing.
- Acesulfame-potassium: An artificial sweetener, likely used in trace amounts within the caplet formulation.
N.O. Fury vs. Pre-Workout Explosion: A Comparison
| Feature | Six Star N.O. Fury | Six Star Pre-Workout Explosion 2.0 |
|---|---|---|
| Primary Goal | Enhanced muscle pumps, fullness, and vascularity | Explosive energy, intense focus, and endurance |
| Stimulant-Free? | Yes, contains no caffeine | No, contains 320mg of caffeine per two scoops |
| Format | Caplets (pill form) | Powder, mixed with water |
| Key Ingredients | L-arginine complex, L-citrulline | Beta-alanine, L-citrulline, caffeine, betaine anhydrous |
| Best for... | Athletes sensitive to stimulants or those who train late | Users needing an energy boost and focus for intense workouts |
| Workout Type | Ideal for pump-focused training sessions | Suited for high-intensity, energy-demanding workouts |
How to Use N.O. Fury for Maximum Effect
Six Star N.O. Fury is designed for simple, convenient dosing. According to product instructions, a standard serving consists of three caplets to be taken once daily with a glass of water. For workout days, it is recommended to take the serving approximately 30 to 45 minutes before starting your training session to allow the ingredients to be absorbed and take effect. On non-training days, it is suggested to take the serving in the morning to maintain elevated nitric oxide levels throughout the day. It is always important to read the full label and stay well-hydrated throughout the day when using this or any other supplement.
Potential Benefits and Considerations
The stimulant-free nature of N.O. Fury is a major advantage for certain users. For those who train in the evening, avoiding a caffeine-based pre-workout can prevent sleep disruption. It is also suitable for athletes who are sensitive to caffeine or other stimulants, providing a way to improve workout performance without the jitters, anxiety, or crashes that can come with stimulant-heavy products. However, individuals with pre-existing heart conditions should consult a doctor before use, as nitric oxide boosters can affect blood pressure.
Conclusion: Is Six Star N.O. Fury Right for You?
Six Star N.O. Fury is a straightforward, stimulant-free pre-workout designed for one main purpose: enhancing muscle pumps by boosting nitric oxide production through a blend of L-arginine and L-citrulline. The caplet form offers convenience for those who prefer not to mix powders. While lacking the energy-boosting effects of caffeine, it provides a solid foundation for improved blood flow and endurance during pump-focused training. For individuals seeking to maximize vascularity and muscle fullness without stimulants, or for those who train late in the day, understanding what are the ingredients in Six Star No Fury confirms it's a suitable and purpose-built option.

Final Thoughts on Ingredient Transparency
Though Six Star discloses the active ingredients, the 3,000mg Nitric Oxide Matrix is a proprietary blend. This means the exact amounts of each arginine form and citrulline within that blend are not disclosed on the label. While this is a common practice in the supplement industry, some consumers prefer to know the precise dosages of each active component. However, the blend's effectiveness is supported by positive customer reviews and its continued availability suggests it provides the intended benefits for many users.
