David and Adam Nagy are two brothers-slash-mad-coffee-scientists from London who have accomplished the unthinkable: they have created the “first colorless coffee drink in the world.” And they did it with all-natural ingredients! That means no preservatives, artificial flavors, stabilizers, or sweeteners. Just high-quality Arabica coffee beans infused with pure water.

“We are heavy coffee drinkers. Like many other people we struggled with the teeth stains caused by it. There was nothing on the market that would suit our needs so we decided to create our own recipe,” David tells the Evening Standard.

“Because of the hectic lifestyle we lead we wanted to make a refreshing ready-to-drink coffee which provides the boost but is low in calories.” Most people going to work early in the morning grab a coffee to help them wake up. However, drinking coffee can stain your teeth significantly, which might be why the demand for teeth whitening from a Dentist in Land O’ Lakes has been so high recently. People want to have clean teeth, but unfortunately coffee doesn’t help. Booking regular appointments with your local dentist might be an idea to have your teeth cleaned, and also drinking this colorless coffee will most likely have a positive impact.

You can currently pick up a two-pack of CLR CFF for around $7 or a five pack for around $17 from the company’s official website.
