Head-to-head evidence comparison — which supplement is right for you?
Electrolyte Complex vs Exogenous Ketones: Electrolyte Complex has the stronger overall evidence (7 vs 4/10); they're alternatives for athletic performance — the best pick depends on your goals. Take the 60-second quiz for a pick tailored to your goals.
Electrolyte Complex wins 2 of 3 categories. Both are solid choices — the best pick depends on your specific goals.

Sodium 1000-3000mg, Potassium 1000-3500mg, Magnesium 200-400mg daily (varies by needs)
Before/during/after exercise, Throughout the day on keto/fasting
Powder or capsules with balanced electrolyte blend
Ketone ester: 25 g per dose is the standard clinical unit. Salts: no established effective dose — the mineral load caps them below useful ketosis
any
Ketone monoester if you want actual ketosis — the salts largely cannot get there
Risk of overshooting sodium in particular. The frequently quoted toxicity figures for sodium-BHB come from SEPTIC MICE given it by central-catheter parenteral nutrition, not from oral use in healthy people — treat this as a reason to count the mineral load, not as evidence of a specific human hazard.
With ESTERS, an electrolyte product is a reasonable pairing for fluid shifts. With SALTS it is largely redundant and potentially excessive — count the minerals in the ketone product toward your daily total first.

Electrolyte Complex has a higher evidence score (7/10 vs 4/10) and wins in 2 of 3 categories.
For athletic performance, Electrolyte Complex has a higher relevance score (60 vs 25).
