The Science of Smart Hydration

Water is life — but not all water is absorbed equally. Just drinking more isn’t always enough. The real key to hydration lies not in how much you drink, but how well your body absorbs it.

When you drink plain water, much of it simply passes through your digestive system. For water to truly hydrate, it needs help entering your cells — and that’s where smart hydration science makes all the difference.

Inspired by the science behind Oral Rehydration Solutions (ORS), LINGTEA is designed to work with your body — not just by supplying hydration, but by supporting absorption at the cellular level.

Our formula uses a carefully balanced 2:1 ratio of sodium to glucose, which activates a natural hydration transporter in your body called SGLT1. This mechanism allows both water and electrolytes to move efficiently from your gut into your bloodstream — helping your body rehydrate quickly and effectively.

Unlike sugary sports drinks that rely on heavy sweeteners or artificial ingredients, LINGTEA delivers hydration without the overload. The science is real — but the experience is light, clean, and easy to enjoy every day.

While ORS products are typically used in clinical settings and follow a recommended osmolarity range of 200–260 mOsm/L (based on WHO/UNICEF guidelines), LINGTEA is not classified as an official ORS. Instead, we’ve intentionally formulated our blend at a gentler 180–195 mOsm/L — optimized for daily comfort, faster absorption, and a refreshingly balanced taste.

Just like salt draws moisture from cabbage during kimchi-making (김장), or how plum syrup pulls hydration from fruit, LINGTEA draws water into your body through the same principle — osmosis. This helps your cells retain what they need to function, recover, and perform at their best.

With up to 90% hydration absorption within an hour, LINGTEA gives your body the hydration it needs — without the sugar crash or synthetic overload of typical sports drinks.

This isn’t just hydration to quench your thirst — it’s hydration that fuels your performance, restores balance, and helps you feel like yourself again.
