Flavored water went viral on TikTok under the WaterTok name, and Skinny Mixes’ Sugar Free Mermaid Syrup is one of the bottles that rode that wave. Plenty of shoppers want to know if it deserves the attention.
The bottle costs $8.99, and its 1,975 reviews average 4.8 out of 5. That is more feedback than almost anything else in the brand’s catalog.
The brand reports eight separate sellouts since WaterTok adopted it. We read a large share of the reviews, plus the ingredient label, to see whether the hype holds up.

Flavor and Ingredients
The flavor is coconut, pineapple and citrus. The brand markets it as a tropical, magical mix.
The label breaks down like this:
- Sweeteners: sucralose and acesulfame potassium
- Preservatives: sodium benzoate and potassium sorbate
- Color: FD&C Yellow No. 5 and Blue No. 1
- Everything else: water, citric acid, natural and artificial flavors and xanthan gum
Servings and Label Details
A 750ml (25.4 fl oz) bottle yields 25 servings. In each serving, calories, sugar and carbs are all at zero.
The syrup is made in the USA. It is kosher and gluten-free, and the formula has no aspartame.
What Buyers Say
Reviewers give it a 4.8 average and a 94% recommend rate, which is impressive for 1,975 reviews. Many say it tastes like a piña colada.
In most mixes, the coconut comes through stronger than the pineapple.
One customer said everything they stirred the syrup into tasted amazing. Another said it made their water seem like a piña colada.
Complaints run the other way from what you might guess. A few reviewers find it overly sweet or wish for a bolder flavor, rather than calling it weak or artificial-tasting.
Ways to Use It
Most reviewers pour it into plain or sparkling water, WaterTok style. Cocktails work too, mainly rum-based recipes, since a piña colada flavor already suits them.
Do not expect a coffee syrup like the brand’s vanilla and caramel options. Coconut and pineapple are not as natural a fit for coffee.
Pour less than the label recommends when the base is water rather than something heavier. Sucralose and acesulfame potassium sweeten this flavor, not the brand’s natural line.
Too much syrup is the usual reason a first-time buyer feels let down.
Against Other Flavors and Torani
Of all the Skinny Mixes flavors, Mermaid has collected the most reviews. Sugar Free Salted Caramel and Sugar Free Vanilla score slightly higher on average.
Torani, a coffee-shop staple, has no flavor that matches this one directly. It does not sell an equivalent tropical blend, which helps explain why this bottle gathered its own following.
Should It Go in Your Cart?
A flavored-water syrup with a proven record beyond the viral buzz is easy to justify, and this is the simplest such pick in the Skinny Mixes catalog. Pour lightly at first, then adjust to taste.
Skip it if sucralose is something you avoid. This flavor is not part of the natural-sweetener line yet.
