Cure Hydration

Cure Hydration is the sole Certified B Corp on this list, using a coconut water base to deliver 240 mg of sodium and 310 mg of potassium at a WHO-ORS optimized ratio. Its 100 mg of magnesium per serving matches Ultima Replenisher's best-in-class magnesium dose but with a sodium level four times higher — 240 mg vs. 55 mg — ensuring better rehydration for moderate activity. The 4 g of sugar per serving, derived naturally from coconut water rather than added sweeteners, suits clean-label consumers. A recent Target launch has expanded its retail reach. Heavy sweaters will find the sodium insufficient compared to LMNT's 1,000 mg. This is the ethical choice for plant-based buyers prioritizing ingredient provenance and certification over mineral density or cost.
