6 Best Electrolyte Supplements for Endurance and Heat

LMNT Sparkling delivers ~1,000mg sodium per serving in a sparkling-beverage format — the formula keto athletes and endurance racers actually need. Tastes like a flavored salt-water; that's the point.

Liquid I.V. Hydration Multiplier uses cellular-transport technology (glucose co-transport) to speed water absorption — useful during intense exercise or rehydration after illness.

SaltStick Electrolyte Capsules are the endurance-athlete's preferred format — pop a capsule during long runs or cycling where you don't want to carry flavored powder. Pure sodium + potassium + magnesium.

Venture Pal chewable tablets deliver electrolyte content in a chewable format at the category's lowest price — for users testing electrolyte supplementation without committing to a premium brand.

Globe Electrolyte Replacement Tablets are a budget alternative to Nuun in the effervescent-tablet category. Similar sodium range, lower price, less brand recognition.
