Limited Edition Pruvit Keto OS Flavors – The Complete List

Pruvit is not only the leader in Pure Therapeutic Ketones, they also provide a wide variety of limited edition flavors for their flagship product line, Keto OS.

Pruvit is constantly experimenting with new Keto OS flavor types to keep ketone-lovers coming back for more. New flavors are most common to show up during seasonal promotions, and the flavors that get the best feedback from the community can potentially become mainstay products in the online store.

We’ve put together a list of past and present Pruvit flavors so that you can keep track of the latest and greatest. Products that have a name that isn’t obvious to what the flavor is, we will add to the description so you can know what to expect.


Keto OS NAT is the most popular Pruvit formula. These ketones are developed using a proprietary natural fermentation process that makes it the most bio-identical ketone to what your body naturally produces. Learn more about Keto OS NAT.

The First Pruvit Ketone Formula

Keto OS v1.2 Orange Dream

Keto COS v1.2 Orange Dream (Retro) – Released 10/15/15

 The Pruvit Keto//COS version 1 series is what started it all. It comes in a delicious flavor that tastes like an orange creamsicle and has added MCTs. In v1.2 the salts are all sodium salts. Sodium salts have a faster uptake and therefore create a quicker spike in ketones. People consuming retro version 1.2 will generally experience the effect of the ketones much quicker and stronger. Pruvit will bring this product back occasionally during limited time promotions for those who miss a taste of the past.
