Oath Clear Protein Refreshers Review: 20g Protein That Drinks Like Juice

Oath Clear Protein Refreshers White Grape Pear and Raspberry Grapefruit with iced drinks

If you hate thick protein shakes, this is 20 grams of protein that drinks like juice. Oath just launched Clear Protein Refreshers, and I tried White Grape Pear and Raspberry Grapefruit to see if they fix the two biggest problems with clear whey: the foam and the aftertaste.

Who Makes Oath?

Oath is part of Trove Brands, the same family behind Owala and BlenderBottle. I mixed these in their Strada bottles, which I've been using for quite some time, and they're pretty nice. The Strada tumbler closes the straw hole, so you can shake it without spilling anywhere.

The Foam and Aftertaste Test

Clear whey isolates usually foam like crazy, and the aftertaste can be horrible. With both of these, there was very little foam, even right after mixing, and there was no bad aftertaste.

How Do They Taste?

White Grape Pear, 9.2/10: That is really good. Clear whey isolates keep getting better, and this is no exception. It literally tastes like I'm drinking grape juice, with a little bit of pear in there too. It's refreshing, light and enjoyable.

Raspberry Grapefruit, 9.3/10: This was my first time sipping protein through a straw. It's light and refreshing, and it doesn't smack you in the face, so it's something you can sip on throughout your day. You get both flavors, but it's mostly raspberry, and there's no aftertaste.

Watch my taste test.

Bottom Line

Oath Clear Protein Refreshers give you 20 grams of whey isolate for 100 calories and 2 grams of sugar, with very little foam and no bad aftertaste. Raspberry Grapefruit edges out White Grape Pear, 9.3 to 9.2, and both are light, refreshing and easy to sip on.
