Every endurance athlete shares the same goal: to go further, faster, and stronger. But the sports nutrition market is flooded with products making bold claims–often without the science to back them up. The noise can be overwhelming, and the stakes are too high for guesswork.

Blonyx takes a different approach. We focus on evidence, not marketing hype. This guide focuses exclusively on supplements backed by real research–the ones that have demonstrated real, measurable improvements in endurance performance, recovery efficiency, and long-term training adaptation.

The science is clear on what works and what doesn't. Our job is to translate it into practical tools that help you perform when it matters most. Because endurance athletes deserve nutrition strategies based on proof, not empty promises.

No fluff. No false claims. Just the supplements that science has proven can make a real difference in achieving ambitious athletic goals.

Dietary nitrates, found abundantly in beetroot, are converted in the body to nitric oxide (NO). NO plays a crucial role in vasodilation, improving blood flow and oxygen delivery to working muscles. This means your body uses less oxygen to produce the same amount of power, increasing efficiency and delaying fatigue, particularly in sub-maximal to high-intensity efforts.

Beta-alanine works by increasing carnosine levels in muscle tissue–a natural buffer that neutralizes the acid buildup responsible for that familiar burning sensation during intense efforts. When muscles can better manage this metabolic stress, they maintain function at higher intensities for extended periods. The research consistently shows that beta-alanine supplementation enhances the body's ability to sustain power output when acidosis would normally force a slowdown.

While often associated with strength, Creatine and HMB (Beta-Hydroxy-Beta-Methylbutyrate) offer distinct benefits for endurance athletes. Creatine supports rapid energy production for surges and repetitive high-power outputs, while HMB helps prevent muscle breakdown during intense or prolonged training, preserving lean mass and accelerating recovery, allowing for greater training consistency.

Endurance performance starts with foundational nutrition and hydration. Electrolytes are critical for nerve and muscle function, while a comprehensive multivitamin ensures your body has all the essential micronutrients to support energy metabolism and overall health under the stress of training.

Blonyx operates on a simple belief that endurance athletes deserve nutrition rooted in real science, not hype. Our approach involves continuously monitoring sports science developments to identify what actually works, then translating that evidence into practical solutions. The focus remains on delivering measurable performance benefits through formulations that have proven their worth in controlled studies.

Endurance performance has clear physiological limiters, but those limiters can be addressed through targeted nutrition. The research has identified specific supplements that measurably impact the factors that determine whether athletes maintain intensity or fade when it matters most. Understanding these tools and applying them strategically can be the difference between hitting a wall and breaking through it.
