Keto//OS® NAT is really the next iteration, the new disruptive technology, the new innovation that Prüvit has brought to market.

There are many benefits of ketosis and KETO OS NAT. Here are a few of the top benefits:

  • Fat-Loss: KETO//OS targets and burns body fat with every serving by positioning your body to follow a proven, accepted, and universal fat-loss formula.
  • Appetite Suppresion: Ketones naturally suppress your appetite allowing you to make better choices and eat less frequently.
  • Protect and preserve muscle: Ketones are extremely anti-catabolic (they are protein/muscle sparing) and will preserve and protect your lean tissue during periods of caloric restriction.  The more muscle you preserve, the more fat you burn.
  • Fast & Sustainted Energy: Ketones offer insulin free energy that maximizes your mindset and mental focus while motivating you to move more, do more, and be more.
  • Improved Clarity & Focus: KETO//OS provides a cleaner, quicker energy pathway than glucose while providing very important signaling molecules to the body. 
  • Joint Mobility: Ketones, specifically beta hydroxybutyrate found in Prüvit’s Proprietary Technology, help maintain healthy joint mobility.

Basically the main difference is the process in which it’s manufactured. It is the first and only naturally fermented ketone that’s ever been developed. And what this means is that there’s no possibilities of any contaminants being inside of Keto OS NAT which ultimately is going to help increase the bioavailability and absorption of this technology. So what can people look for when biohacking their system with Keto OS NAT? Really Keto//OS® NAT is there to provide this super fuel, this alternative source of energy that your body can then take up and utilize for a variety of different functions. Some people come in and are looking at optimizing body composition, some people come in and they really need that energy they need that focus, they need that light switch to turn on and ketones themselves are really allowing your body to do that and Prüvit is the only company that has the right key that your body can identify that your cells actually take up and utilize and are able to recognize to allow that fuel source to be take up and maximumly utilized at the cellular level.
