Keto OS 3.0 (Ketone Operating System) is a new version of the beta-hydroxybutyrate and caffeine drink mix from Prüvit. It comes with a new flavour - Chocolate Swirl. Keto OS 3.0 is suitable for vegans. It is also dairy- and gluten-free.

Here you can read an in depth explanation of how beta-hydroxybutyrate (exogenous ketones) work.

Keto OS 3.0 is optimised for faster absorption, but also to last longer. It is made with caffeine and currently available in the canisters and the On-the-Go packs.

Other options are 'Keto OS', which does not have any caffeine elements, 'Keto OS Charged', which has caffeine, and 'Keto Kreme', an alternative to coffee since it is produced from coconut.


Dr. Jacob Wilson and Ryan Lowry have improved the formula by optimising Ketone – BHB Salt ratio to get a much faster peak and into the system. This provides sustained ketone levels throughout the day.

They have also added ketogenic Amino Acids and Short Chained Fatty Acids that use the same transporters as ketones. This makes sure the users are getting that same direct quick uptake into their system.

This latest version includes a prebiotic, a food source which helps the good bacteria in the gut fight the bad bacteria more effectively.
