Electrolytes

Expert Positions

Andrew Huberman

Strongly Recommends Supplementation

Peter Attia

Context-Dependent — Cautious on Sodium

Rhonda Patrick

Recommends via Whole Foods

Bryan Johnson

Uses Sodium-Free Substitutes

Mark Hyman

Recommends Electrolyte Balance

The Verdict

All 5 experts acknowledge the importance of electrolytes (sodium, potassium, magnesium) for health and performance, but they diverge sharply on sodium intake. Huberman is the strongest advocate for deliberate sodium supplementation, dedicating a full episode to the topic. Attia takes a cautious, clinical approach — he warns that high sodium triggers fructose production and raises blood pressure, while also explaining the critical role of proper hydration with electrolytes. Patrick emphasizes potassium and magnesium from whole foods over sodium supplementation. Johnson uses sodium-free salt substitutes and experienced firsthand electrolyte imbalance during his sauna experiments. Hyman warns that over-drinking plain water without electrolytes is dangerous, but focuses more on reducing processed-food sodium than supplementing it.
