Buoy review: what they sell
Buoy's drops are truly unflavored, so they work in whatever you already drink. The brand says the Hydration Drops formula is clinically proven to hydrate 64% better than water alone and that its products are third-party tested.
Beyond hydration, Buoy sells Digestion, Rescue (extra-strength, higher sodium) and Brain Health Drops, plus a newer Rainforest line. It runs a Chronic Illness Support Program and lists HSA/FSA-eligible options.
