Sports Supplements & Hydration Strategy

The sports supplement market is enormous, loudly marketed, and largely unregulated — which makes it hard for athletes to know what’s actually worth taking. H2O Nutrition provides evidence-based guidance on supplements and builds individualized hydration protocols so athletes stop guessing and start using strategies that are actually supported by research.

Cutting Through Supplement Marketing

Most supplement marketing is built around anecdote, not evidence. Andrea Dacey, RDN, CSSD helps athletes evaluate what they’re taking (or considering) against what the research actually supports for their specific sport and goals — and just as importantly, helps identify what’s safe to skip.

What We Cover

Evidence-based supplement review — evaluating creatine, caffeine, beta-alanine, protein powders, and other common products against your specific training and goals
Third-party testing and safety — especially critical for NCAA and other tested athletes, where a contaminated supplement can trigger a positive test
Sweat-rate testing and sweat sodium concerns — building a hydration plan based on your actual fluid and electrolyte losses, not a generic “8 glasses a day” rule
Electrolyte strategy — tailored to your sport, session length, and climate/heat exposure
Race and competition-day protocols — specific hydration and supplement timing for competition, distinct from daily training

Who This Is For

Athletes overwhelmed by conflicting supplement marketing
NCAA and other tested athletes needing safety guidance on supplement choices
Athletes training or competing in hot or humid conditions
Anyone dealing with cramping, heat-related performance drop-off, or excessive thirst/fatigue during training
