What Is Buoy?
Buoy is a liquid electrolyte product designed for people who want hydration support without sugary drinks, chalky powders, or strong flavors. You can add it to water, tea, coffee, or other drinks without changing the flavor much.
That makes Buoy especially appealing for everyday hydration habits. It is simple, subtle, and easy to use consistently.
What Is LMNT?
LMNT is a zero-sugar electrolyte mix known for its very high sodium content. It is designed more for performance hydration than casual sipping. People often use it for workouts, hot weather, fasting, sauna days, or low-carb routines where sodium needs may be higher.
The tradeoff is that LMNT is much stronger than Buoy. That is why some people love it and others find it too intense for normal day-to-day hydration.
Key Differences That Matter
1. Sodium Content
This is the biggest difference. Buoy is much gentler and makes sense for routine hydration. LMNT is intentionally high in sodium and is built for situations where you need more electrolyte replacement.
2. Taste
Buoy is nearly flavorless, which makes it easy to add to drinks without changing the experience much. LMNT has a much stronger taste and feels more like a dedicated performance product.
3. Convenience
Buoy wins on convenience because drops are easy to carry and easy to add to almost anything. LMNT is still simple, but it is more of a full drink mix than a subtle add-in.
4. Best Use Case
Buoy fits all-day hydration. LMNT fits higher-need situations like workouts, travel, heat, sauna sessions, fasting, or days when you know you are losing more sodium.
