Our Verdict
Gnarly Hydrate is one of the best-balanced electrolyte powders in this batch, providing meaningful amounts of all five major electrolytes (250mg Na, 100mg K, 80mg Mg, 100mg Ca, 135mg Cl) plus B vitamins. The NSF Content Certified status (with heavy metals, microbe, and pesticide testing) provides genuine third-party validation. At $0.75/serving ($0.60 with subscription), it's also among the most affordable. Note that NSF for Sport certification only applies to the Orange Pineapple bag, not stick packs.
