Research-Backed Assessment

Player Performance Tax Calculator

Professional athletes are losing performance—and your team is losing money—to correctable mineral deficiencies. Quantify the hidden cost and discover the ROI of addressing it.

68+ Research Citations
30 Symptoms Assessed
3 Mineral Frameworks
Research Finding: Studies show 52-92% of professional athletes are deficient in at least one essential mineral—and most don't know it. This calculator helps you identify the problem and quantify its impact on your roster.

What Is the "Performance Tax"?

The hidden cost of mineral deficiencies on athletic performance

Every day, your athletes may be paying a hidden tax on their performance. Mineral deficiencies don't always announce themselves with dramatic symptoms—they quietly erode recovery, increase injury susceptibility, and reduce output. Athletes play through fatigue they attribute to training. Teams accept cramping as inevitable. Medical staff treats symptoms without addressing root causes.

The Performance Tax is the cumulative cost of this hidden drain: player-days lost to preventable issues, salaries paid for suboptimal performance, and wins left on the table because athletes couldn't perform at their physiological potential.

Our calculator—built on 68+ peer-reviewed research citations—quantifies this tax for your specific roster and shows the ROI of addressing it.

Built on Research

68+ peer-reviewed citations supporting our methodology

Chappell et al. (2018) 8-year study of 192 elite athletes: 22% clinically magnesium deficient
Montain et al. (2019) 39% of endurance athletes hypokalemic at rest; 60% after exercise
Heffernan et al. (2019) Systematic review: 60% of athletes deficient in at least one micronutrient
NCAA Track Study (2025) 92% of athletes under-consuming at least one essential micronutrient
Conservative Methodology: Our prevalence rates (68% Mg, 43% K, 52% TM) represent middle-ground estimates from the research. True deficiency rates may be higher, making our financial impact calculations deliberately conservative.

Frequently Asked Questions

Our calculations are built on 68+ peer-reviewed research citations and use conservative estimates throughout. The deficiency prevalence rates (68% for magnesium, 43% for potassium, 52% for trace minerals) represent middle-ground figures from the literature—actual deficiency rates may be higher. The "days lost per symptom" multipliers are based on documented recovery times and performance degradation research. While individual athlete responses vary, the aggregate impact estimates have proven consistent with real-world outcomes reported by teams using mineral optimization protocols.
The financial impact represents the conservative salary cost of player-days lost to deficiency symptoms. We calculate daily salary (annual salary ÷ season days) × affected player-days. This captures direct downtime and suboptimal performance but does NOT include: replacement player costs, medical treatment expenses, team performance impacts on wins and revenue, or playoff revenue potential. The true cost is likely significantly higher than our calculated estimate.
Theoretically yes, but practically it's extremely challenging. Modern agricultural practices have depleted soil minerals by 20-30% over the past 50 years. Athletes would need to consume approximately 2,000+ additional calories daily of specifically mineral-rich foods to meet their elevated requirements—on top of existing nutritional demands. Additionally, athletic activity increases mineral loss through sweat and metabolism, creating a moving target that diet alone struggles to address.
Most sports supplement programs focus on protein, creatine, and pre-workout compounds—but overlook the mineral foundation these supplements require to work effectively. Creatine, for example, requires magnesium for activation. B vitamins use magnesium as a cofactor. Without adequate mineral status, other supplements may provide diminished returns. The Performance Tax Calculator helps identify whether mineral gaps are limiting the effectiveness of your existing program.
Three key differentiators: First, pico-ionic technology creates mineral particles small enough for direct cellular absorption—bypassing the digestive issues (loose stools, GI discomfort) common with traditional mineral supplements. Second, NSF Certified for Sport® ensures no banned substances and third-party verified purity. Third, liquid format allows precise dosing adjustment based on individual athlete needs and training load. The combination of bioavailability, certification, and flexibility makes these products uniquely suited for professional athletics.
A Team Assessment involves a comprehensive evaluation of your roster's mineral status through symptom mapping, performance data analysis, and protocol recommendations. Schedule a call with Steve Petitt (980-540-1392) to discuss your team's specific situation, timeline, and goals. Most assessments can begin within 1-2 weeks and provide actionable recommendations within 30 days. There's no obligation—the assessment itself provides valuable insights regardless of whether you implement our protocols.
