Why This Exists
Sports nutrition is overpriced. This is the fix.
The endurance nutrition industry is built on a simple premise: athletes will pay premium prices for marginal performance claims. A product that costs $0.30 to manufacture gets rebranded, put in a foil pouch, and sold for $3.50. The "proprietary blend" label exists specifically so you can't reverse-engineer what you're buying.
The underlying science isn't secret. Decades of peer-reviewed research have established exactly what works: multi-transportable carbohydrates in roughly a 1:0.8 glucose-to-fructose ratio, isotonic-to-near-isotonic osmolality, meaningful sodium replacement. The formulas are not complicated. The markup is.
OpenFuel publishes every ingredient, every ratio, and every research citation openly. The goal isn't to sell you anything — it's to give you the same information that sports nutrition companies use to formulate their products, so you can make it yourself, smarter, and cheaper.
