Adding ice to the drink is really very refreshing on a hot day. I brought the drink for a family picnic 🧺 and kite flying. Under the hot sun, and vigorous activities, having the cool flavoured water was really refreshing and satisfying.

Frequently Asked Questions

What does WaterUp taste like?

Refreshing and clean — like fresh-squeezed lemon and lime, without the artificial aftertaste of typical "lemon flavor" drinks. It's lightly sweet, never syrupy.

Think of it as the natural cousin of a sports drink: hydrating, tangy, satisfying, but without the sugar crash or that chalky vitamin powder taste.

We use natural lemon and lime extracts, not just citric acid and flavoring, which is why the taste reads as natural rather than chemical.

Is it natural or artificial?

WaterUp uses natural lemon extract, natural lime extract, natural green tea extract, and added Vitamin C (ascorbic acid). No artificial colors. No artificial flavors. No preservatives.

The product is light yellow naturally — from the citrus extracts themselves, not from coloring agents. That's also why the color may vary slightly between batches, which is normal for natural ingredients.

Is it tested for safety?

Yes. WaterUp is manufactured in a HACCP-certified facility. Each batch is subject to quality control testing and third party lab testing. We can provide a Certificate of Analysis (COA) upon request.

Does it work with cold water or room temperature?

Yes to both. Cold water is our recommendation because it brings out the brightest citrus notes, but room temperature works perfectly.

What sweeteners do you use?

WaterUP uses sucralose for that clean, sweet taste with zero sugar and zero calories.

How much Vitamin C does it contain?

One sachet provides approximately 70% of your recommended daily Vitamin C intake — sourced from a combination of natural lemon extract and added ascorbic acid (Vitamin C). One serving is enough to noticeably support your daily Vitamin C goals, especially helpful for active people, those frequently in air-conditioning, or anyone wanting daily immunity support.

Can I drink more than one sachet a day?

For most healthy adults, 1-2 sachets per day is the sweet spot. The Vitamin C content of one sachet already covers about 70% of your daily needs, and two sachets approach the upper limit of recommended daily Vitamin C intake. More than two sachets daily isn't harmful for most people but is unnecessary.

When is the best time to drink it?

Three popular moments among our customers:

Morning — start the day hydrated with a Vitamin C boost.
Mid-afternoon (around 3pm) — replace the sugary coffee or bubble tea craving with something equally refreshing but healthier.
After meals — help cleanse the palate and aid digestion, especially after rich or oily food.

There's no wrong time. Many customers keep a few sachets at their work desk, in their gym bag, and in their travel kit.

How long does WaterUp stay fresh once I open the box?

Each sachet is individually sealed and shelf-stable. The box itself has an 24-month shelf life from the date of manufacture (printed on the packaging). Once you open the outer box, the individual sachets remain fresh until their printed expiry date — no need to refrigerate.

How is WaterUp different from a sports drink or electrolyte mix?

Sports drinks are designed for athletes, high in sugar and sodium, calibrated for intense physical exertion.

WaterUp is designed for everyday life: low calorie, zero sugar, mild flavor, and built around taste enjoyment rather than performance.

If you're running a marathon, drink a sports drink. If you're sitting at a desk, walking around, working out moderately, or just want to enjoy drinking more water — that's where WaterUp fits.
