When people think about sports nutrition, they think protein, carbohydrates, electrolytes. Magnesium rarely makes headlines, or, blog posts. But for soccer players who cover 10+ kilometres per match, sprint repeatedly, change direction hundreds of times, and are expected to make sharp decisions under fatigue — magnesium is not optional. It should be a core foundation of your nutritional preparation for games.
The inclusion of Magnesium in the P90 Labs Performance Gel was a scientifically backed decision.
Muscle Function & Cramp Prevention
Magnesium plays a central role in muscle contraction and relaxation. Every time a muscle fires — whether it's a 40-yard sprint, a sharp cut, or a quick pass — magnesium is working in the background to regulate that process. Without adequate levels, the balance between calcium (which triggers contraction) and magnesium (which enables relaxation) breaks down.
The result? Cramping. Tightness. Muscle fatigue that sets in earlier than it should. For soccer players, this can be the difference between maintaining explosive output in the 80th minute versus pulling up short. Sweat-induced magnesium loss during a 90-minute match is significant — and most players are not replacing it.
Energy Production at the Cellular Level
Magnesium is required for the production of ATP — adenosine triphosphate — the molecule your body uses as its primary energy currency. Without magnesium, your cells cannot efficiently convert the carbohydrates you consume into usable energy. This means that even with optimal carbohydrate intake, a magnesium deficiency creates a bottleneck in your energy system.
This is why we were deliberate about pairing our dual-carbohydrate system with magnesium. The carbohydrates deliver the fuel. Magnesium ensures your cells can actually use it. One without the other is an incomplete solution.
Cognitive Sharpness & Decision Making Under Fatigue
Soccer is not just physical. It's a high speed mental game. Reading the game, tracking runners, deciding when to press and when to hold — these decisions happen in fractions of a second, and they happen while your body is under extreme physical stress.
Magnesium supports healthy neurotransmitter function and helps regulate the nervous system's stress response. Research has shown that magnesium deficiency is associated with increased cortisol levels — the stress hormone that impairs focus and reaction time. Maintaining magnesium levels during a match helps keep the nervous system calm, reactive, and sharp. When the game is tight and the margin for error is zero, cognitive clarity is not a nice bonus, it's a necessity.
Electrolyte Balance & Hydration Efficiency
Most electrolyte products focus on sodium and potassium. These are important — but they are only part of the picture. Magnesium works alongside these electrolytes to regulate fluid balance at the cellular level. It supports proper sodium-potassium pump function, which governs how efficiently your cells absorb water and maintain hydration status.
In practical terms: you can drink plenty of fluid during a match and still perform poorly if your electrolyte profile is incomplete. Magnesium fills a gap that most sports drinks leave open.
Recovery Between Sessions
The demands of a soccer periodization load, whether pre-season, in-season, or off-season are heavy. Training through the week, matches on the weekend, sometimes twice a week. This makes recovery just as important as performance. Magnesium has been widely studied for its role in reducing inflammation, supporting sleep quality, and accelerating muscle repair after intense exercise.
Players who recover faster train harder the next day. And players who train harder get better. Magnesium is part of the recovery chain that most supplement formulas do not address adequately.
Why We Included It in Our Formula
Our formula was built around one question: what does a soccer player actually need during training and a match? Not a generic athlete. Not a marathon runner. A soccer player.
The answer kept coming back to the same set of demands: sustained energy, muscular endurance, cognitive sharpness, and resilience against fatigue. Magnesium sits at the intersection of all four. It is not a marketing ingredient — there is no buzz around it, no headline claim. It is simply a mineral that the body needs to function at its highest level, that is consistently depleted through sweat and exertion, and that is consistently underrepresented in sports nutrition products.
We included it because leaving it out would have been a shortcut. And this formula was not built on shortcuts.
This was built to develop the next generation of soccer players in North America.
