Guide
Liquid I.V.: a sugar packet with a medical-sounding name
A "hydration multiplier" that is 11g of sugar per serving and the same electrolyte profile as a pinch of salt. Skip it — and what to drink instead.
Guide
Prime Hydration: the Logan Paul drink kids carry like a status symbol
A neon sports drink marketed to children, lawsuit-grade caffeine in the energy line, and a hydration claim that doesn't survive its own ingredient list. Skip it — and what to drink instead.
Guide
Liquid Death: skull cans, supermarket water, premium markup
A heavy-metal aesthetic wrapped around boring mountain water. Hydration is real. The €2.50 mark-up is marketing.
Vetted under the Codex charter
