About Electrolyte Expert
We're on a mission to help you find the best electrolyte supplements through science-backed reviews, honest comparisons, and expert guidance.
Our Story
Electrolyte Expert was founded in 2024 by Dr. Sarah Mitchell after she spent months struggling to find reliable, evidence-based information about electrolyte supplements. As a nutritional scientist and registered dietitian, she was frustrated by the lack of transparent, data-driven reviews in the supplement space.
“I was seeing patients who were spending hundreds of dollars on electrolyte supplements that didn't deliver what the labels promised,” says Dr. Mitchell. “I realized that if a PhD nutritionist couldn't easily compare these products, the average consumer had no chance.”
Today, Electrolyte Expert is trusted by over 50,000 monthly readers who rely on our comparisons to make informed decisions about their hydration and supplement choices. We've tested over 40 electrolyte products and published 50+ in-depth guides covering every aspect of electrolyte supplementation.
Our Testing Process
Every product goes through our rigorous 4-step evaluation before we publish a review
We purchase every product at retail price — no free samples from brands. This ensures unbiased reviews and real-world pricing data.
Each product is tested for a minimum of 30 days. We use it in real scenarios: workouts, fasting windows, daily hydration, and recovery periods.
We cross-reference label claims with third-party lab results and NSF/Informed Sport certifications to verify ingredient accuracy.
Products are scored on electrolyte content, taste, mixability, value, ingredient quality, and certifications. Our scoring rubric is publicly available.
