Navigating the supplement market for a nitric oxide booster can feel overwhelming with so many products making big promises.
Instead of guessing, focus on the science behind ingredients that enhance blood flow and workout performance. With transparent formulas using researched doses of components like L-citrulline and innovative options like Nitrosigine®, you can pick a supplement that delivers real results for your training.
What Nitric Oxide Does for Your Performance
Why Nitric Oxide Matters in Exercise
Nitric oxide, or NO, plays a key role in your workouts as a vasodilator that boosts your capacity to train harder. It enhances muscle fiber power and speed by improving contractility, which benefits both strength and endurance efforts.
Beyond widening blood vessels, nitric oxide offers multiple advantages for athletes. Increased NO levels reduce the oxygen needed during exercise, support muscle growth, improve energy production in cells, and speed up recovery. These wide-ranging effects make NO boosters a core supplement for dedicated trainees.
Additionally, NO helps with energy creation in muscles, efficient breathing, and maintaining balance in cellular processes. It also promotes better blood flow, oxygen delivery, and glucose use in active muscles, setting the stage for longer-lasting performance and growth.
How Your Body Makes Nitric Oxide: Two Main Paths
Knowing how nitric oxide forms in your body helps you choose the right supplement. NO production happens through two pathways, one dependent on nitric oxide synthase enzymes using L-Arginine and L-Citrulline, and another independent path using nitrate and nitrite.
In the enzyme-dependent path, nitric oxide synthase turns L-arginine into NO. L-Arginine acts as the primary source, while L-Citrulline supports it by converting back to L-Arginine. This path works well under normal conditions and responds effectively to citrulline supplements.
The independent path kicks in during tough workouts. Dietary nitrate boosts NO stores in muscles, especially in low-oxygen or acidic environments during intense exercise. Using both paths together, by combining different NO sources, often gives better results than a single ingredient.
Key Ingredients That Boost Nitric Oxide: What Works
L-Citrulline and Citrulline Malate: Reliable Blood Flow Support
L-Citrulline stands out as a trusted choice for increasing nitric oxide, often outperforming L-Arginine in studies. As citrulline malate, it raises NO levels and enhances high-intensity exercise outcomes more effectively than arginine alone.
Citrulline works by avoiding the breakdown that arginine faces in the gut. It converts to arginine in the kidneys and blood vessels, right where NO production is crucial. Citrulline malate adds malic acid to further support energy during tough sessions through metabolic processes.
Studies suggest 6 to 8 grams of citrulline malate as the ideal dose for blood flow and performance gains. Bucked Up includes this in products like Bucked Up and Woke AF to help with muscle pumps and stamina.


Nitrosigine®: Enhanced NO Delivery for Blood Flow
Nitrosigine®, a specialized blend of arginine, inositol, and potassium silicate, offers improved absorption for nitric oxide support. It focuses on better blood flow and vascular function.
In Bucked Up’s Mother Bucker pre-workout, Nitrosigine® pairs with L-Citrulline to maximize nitric oxide effects, aiming for stronger muscle pumps and performance suited for experienced users.

Additional Ingredients to Support Blood Flow
While core NO boosters lay the groundwork, other components can enhance their impact. Here are a few found in Bucked Up products:
- Hydroprime® Glycerol in Mother Bucker supports hydration and blood volume for better pumps.
- Astragin®, used across Bucked Up pre-workouts, improves absorption of citrulline to ensure the active ingredients work fully.
- Beta-alanine, included in many formulas, helps with endurance by reducing lactic acid buildup, allowing longer high-intensity efforts alongside NO benefits.

This range lets you match a nitric oxide formula to your training background, stimulant comfort, and goals, ensuring a personalized approach.
Finding the Best Nitric Oxide Booster for You
Picking a nitric oxide pre-workout means weighing your workout history, stimulant tolerance, and specific aims. NO supplements often help less-experienced or moderately active individuals more than elite athletes, though advanced users can still gain from targeted products.
If you’re starting out, Bucked Up’s main pre-workout offers a balanced entry with citrulline malate and 200mg caffeine for energy and pumps. Added elements like AlphaSize® Alpha GPC for focus and beta-alanine for endurance round out the mix.
For intermediate users wanting more intensity, Woke AF keeps citrulline malate as a base but boosts caffeine to 333mg, fitting those used to standard doses yet seeking solid NO support.
Seasoned athletes might prefer Mother Bucker, blending L-citrulline, Nitrosigine®, and Hydroprime® Glycerol for pumps, plus 400mg of dual-release caffeine and nootropics like Huperzine A for focus and connection during lifts.
If you avoid stimulants, Bucked Up’s Non-Stimulant Pre-Workout provides nitric oxide benefits without caffeine, ideal for late sessions or sensitivity, using citrulline malate with focus and energy components.
Keep in mind that how well a supplement works depends on dose, timing, exercise type, and your fitness level. Choose a product that fits your needs rather than just the strongest option.
