What Is Liquid IV?

It’s widely available in the UK via Amazon and major retailers, and has built a strong following among athletes and travellers.

The Key Difference — Hydration vs Complete Daily Performance
Liquid IV was designed for one thing: rapid rehydration. It does that well, using a glucose-sodium ratio to drive water absorption. But glucose means sugar — and for daily use, that adds up.
vybey Smart Hydration+ was designed for daily use across your whole lifestyle — not just post-workout or post-flight. The addition of nootropics and prebiotics means every sachet is doing three jobs simultaneously:
- Rehydrating your body
- Supporting your focus and cognitive performance
- Feeding your gut microbiome

Sugar — Why It Matters for Daily Use
Liquid IV’s CTT technology relies on glucose (sugar) to drive electrolyte absorption. This is effective for acute rehydration but makes it less suitable as a daily drink — particularly for those managing blood sugar, following a low-sugar diet, or simply trying to avoid unnecessary sugar intake.
vybey Smart Hydration+ achieves effective hydration with zero added sugar, making it genuinely suitable for daily use without compromise.
Who Should Choose Liquid IV?
Liquid IV is a good fit if you:
- Need rapid rehydration after intense exercise or illness
- Are already familiar with the brand and happy with the cost
- Only use electrolyte drinks occasionally rather than daily
