Liquid I.V. is a legitimate and effective electrolyte product for rehydration, particularly for athletes or those experiencing fluid loss, but its high sugar content makes it less ideal for general daily use. While the product itself is widely considered safe and functional, many users report significant frustrations with the brand's direct-to-consumer website, including poor customer service and difficult subscription management. It is strongly recommended to purchase Liquid I.V. from reputable third-party retailers like Amazon or local stores, where it is often cheaper and avoids the issues associated with their official website.
