Fuel for Functional Athletes Chasing PRs
The Blonyx System helps athletes training for HYROX® and CrossFit® fuel the moments that matter while building habits that compound into long-term performance.
A Series of Consistent Inputs to Your Training that Build Over Time
We design sports nutrition as a system to support the work you repeat, not just the all-out sessions, fitness races, or functional fitness competitions.
Ingredients rooted in research
Each must have a pattern of evidence showing it will help improve your athletic performance.
The right dose at the right time
Consistent daily or strategic use adds up to real, measurable progress in your training.
Built for how athletes actually train
Real-world training is never perfect, so your sports nutrition needs to be reliable.
Where the Blonyx System Meets Your Training
For when your legs lit up and you can't catch your breath, but the workout isn’t done:
Beta-alanine: Taken daily, beta-alanine increases your ability to buffer muscle burn, helping you hold pace through lunges, burpees, and long SkiErg intervals when fatigue spikes.
Carbohydrates: High-intensity intervals burn through glycogen quickly. Strategic carbohydrate intake helps maintain output across long metcons and hybrid sessions.
Nitrates (400mg from beet juice): Nitrates from a high-concentration shot of beet juice taken 90 minutes before training will improve your muscle efficiency, so hard efforts feel more sustainable when your heart rate is pinned.
For repeatable Zone 2 work where sessions can’t be cut short by low energy, dehydration, or lingering fatigue:
Nitrates (400mg from beet juice): Support oxygen efficiency and muscle economy, helping steady runs, row intervals, or mixed-engine sessions feel more controlled with the same perceived effort.
Electrolytes: Help move water into the body more effectively, supporting hydration status during longer or warmer sessions. When hydration is dialled, heart rate drift and perceived effort are easier to manage.
Carbohydrates (drinks or gels): Help ensure longer aerobic sessions aren’t capped by low fuel or unexpected energy dips.
HMB: Helps reduce muscle damage during higher-volume blocks, supporting recovery so aerobic volume can stay consistent week to week.
For efforts that demand force production and are limited by how well you can produce force repeatedly, manage fatigue, and recover between efforts:
Creatine: Supports repeated high-intensity force production, helping you sustain force output across repeated efforts, not just the first heavy set.
Beta-alanine: Buffers lactic acid, allowing you to push through those final reps as fatigue and muscle burn sets in.
HMB: Daily use will support muscle integrity and prime your muscles for progress in strength and power training.
For when you just don’t feel quite ready and yesterday’s work is still in your system, a sign that your body's recovery hasn’t fully caught up:
Protein (from real foods wherever possible): Provides the amino acids needed for muscle repair and adaptation so training stress doesn’t carry forward more than it should.
Creatine: Supports cellular energy availability and training readiness, helping strength and power feel more accessible even when sessions stack up back-to-back.
HMB: Reduces muscle damage from training and supports faster recovery, and is one of the small, daily inputs that compound over time.
Tart cherry: Helps manage soreness and inflammation following high-intensity or high-volume efforts.

What Athletes See in Their Training
I’ve been taking HMB+ Creatine for over a decade, and it’s a non-negotiable for me and my family. The ingredients some of the most researched and trusted there is, with experts like Dr. Andrew Huberman highlighting its cognitive benefits alongside its well-known impact on strength and recovery. Stronger muscles, sharper mind, and a body that bounces back faster? I’m all in.
I've been using Blonyx Beta Alanine, and even in the first month, I noticed less fatigue from training, much quicker recovery, and greater endurance during my sessions! Total game changer.
There are a LOT of protein powders out there, and you want to get the most from the one you choose. Hands down the best part of Egg White Protein Isolate is how easily it mixes and how clean it tastes. It doesn't feel heavy like whey protein powders do. I like that it's simple and straight to the point.
