Our Verdict
Hydrant offers a well-balanced, ORS-inspired formula with 260mg sodium, 200mg potassium, and the added benefit of zinc (1.5mg). The 8-ingredient formula is clean for a flavored product, and the citrate/gluconate mineral forms show quality attention. At $1.23/serving ($0.98 with subscription), it's competitively priced. The inclusion of real fruit juice powder rather than just 'natural flavors' is a plus, though natural flavors are also present.
