Prüvit K1 Ketones: What Is K1 & How Does It Work?
Prüvit K1 is the newest generation of exogenous ketones from Prüvit featuring its patented Tri-Blend Ketone formula. If you're wondering what K1 is, how it works, how it compares with KETO//OS NAT, or how to try it, I'll break it all down below based on my experience with Prüvit and exogenous ketones.

What Is Prüvit K1?
Prüvit K1 is an exogenous ketone supplement designed to provide ketones from an outside source rather than relying only on your body to produce them through carbohydrate restriction or fasting. K1 uses Prüvit's patented Tri-Blend Ketone formula and represents the company's newest generation of ketone technology.
If you're familiar with Prüvit, you've probably heard of KETO//OS NAT. NAT has been one of Prüvit's core ketone products for years, while K1 represents the newer evolution of the company's exogenous ketone lineup. I'll explain the differences between K1 and NAT farther down this page.

Related product: KETO//OS NAT

Who is K1 for?
Prüvit K1 provides exogenous ketones, meaning ketones that come from outside the body. After consuming K1, these ketones enter the bloodstream and can increase circulating ketone levels without requiring your body to first produce all of those ketones on its own.
Normally, your body produces ketones when carbohydrate availability is low, such as during a ketogenic diet or fasting. Exogenous ketones offer another way to introduce ketones into the body, which is why products like K1 are often used by people interested in ketosis, ketogenic lifestyles, and ketone-based energy.
Do You Have to Follow a Keto Diet to Use K1?
No. You don't have to follow a strict ketogenic diet to consume exogenous ketones. However, drinking exogenous ketones and being in nutritional ketosis from your own diet are not exactly the same thing. K1 provides ketones from an external source, while nutritional ketosis occurs when your body increases its own ketone production.
Prüvit K1 vs. KETO//OS NAT: What's the Difference?
If you've used Prüvit for a while, you may be wondering how K1 compares with KETO//OS NAT. Both are exogenous ketone products from Prüvit, but K1 represents the company's newer Tri-Blend Ketone technology, while KETO//OS NAT remains part of Prüvit's current ketone lineup.

Is K1 Replacing KETO//OS NAT?
K1 is Prüvit’s newest evolution in exogenous ketone technology, but KETO//OS NAT is still available from Prüvit today. Rather than assuming NAT has disappeared, I look at K1 as the newest direction in Prüvit’s ketone lineup while NAT continues to be available in a variety of formulas and flavors. As Prüvit’s product lineup evolves, I’ll keep this page updated.
What Are the Potential Benefits of Prüvit K1?
People use exogenous ketones for a variety of reasons, and individual experiences can vary. Prüvit positions K1 as a ketone-based fuel source designed to support energy, focus and physical performance. Rather than thinking of K1 as a treatment or a shortcut, I think it makes more sense to view it as another way to make ketones available to the body.
Sustained Energy
K1 provides exogenous ketones that can be used as an alternative fuel source by the body.
Mental Focus & Clarity
Prüvit positions K1 as supporting mental focus and clarity through ketone-based energy.
Physical Performance
K1 is designed to support physical performance and endurance and can be used before workouts or other
demanding activities.
Hydration Support
K1 contains electrolytes including sodium, calcium and magnesium, which Prüvit includes to support hydration
and ketone utilization.
Individual experiences vary. K1 is a dietary supplement and is not intended to diagnose, treat, cure or prevent any disease.
What’s in Prüvit K1?
At the center of Prüvit K1 is its patented Tri-Blend Ketone formula. Rather than relying on a single form of exogenous ketones, K1 combines multiple ketone technologies into one formula designed to provide an external source of ketones.
K1 also includes electrolytes such as sodium, calcium and magnesium. The exact ingredients can vary depending on the K1 flavor and whether you choose a Charged or Caffeine Free option, so I always recommend checking the current product label for the specific K1 you're considering.
What Is the K1 Tri-Blend Ketone Formula?
Prüvit describes K1's Tri-Blend as a combination of three forms of ketone technology. The idea behind the formula is to combine different sources of exogenous ketones rather than relying on a single ketone source. This Tri-Blend formula is one of the primary differences between K1 and earlier generations of Prüvit ketone products.
Prüvit K1 Flavors & Options
Prüvit K1 is available in several flavors, with both Charged and Caffeine Free options. That makes it easier to choose a version based on flavor preference and whether or not you want added caffeine.

Charged vs. Caffeine Free
Charged K1 contains caffeine, while Caffeine Free provides an option for people who prefer K1 without added caffeine. Prüvit currently offers each of its four U.S. K1 flavors in both formulas.
Which one you choose mostly comes down to personal preference and when you plan to drink it. Someone who already consumes caffeine or wants to avoid it later in the day may prefer Caffeine Free, while others may prefer the Charged version.
What Sizes Does K1 Come In?
K1 is currently offered in 10, 20 and 30-serving options, along with a 20-serving Experience Box. Product options and availability can change, so check the current Prüvit store for the latest selections.
My Experience With Prüvit & Exogenous Ketones
I've been involved with Prüvit and exogenous ketones for many years, going back to the earlier generations of KETO//OS. Over that time, I've watched the products evolve through multiple formulas and generations, from the original KETO//OS products to KETO//OS MAX, KETO//OS NAT and now K1.
That history is one reason I'm interested in K1. I'm not looking at it as someone who just discovered exogenous ketones or Prüvit. I've had the opportunity to watch the products, the company and the ketone category evolve over the years.
My goal with this page isn't to tell you that K1 will produce a specific result. Everyone's experience can be different. Instead, I want to help you understand what K1 is, how it fits into Prüvit's current lineup and what you should know if you're considering trying it.
How to Try Prüvit K1
If you're ready to try Prüvit K1, the easiest way is to view the current K1 options directly through Mr Ketosis & Prüvit. You'll be able to see the latest flavors, Charged and Caffeine Free options, serving sizes, pricing and availability. Because Prüvit's products, flavors and promotions can change, I recommend checking the current store rather than relying on an older price or product list you may find online.
Do I Need a Prüvit Referrer?
Prüvit uses a referral-based shopping system, so you may see a referrer associated with your account or order when shopping through Prüvit. If you use one of the Prüvit links on this page, my referral information is already included in the link, so you don't need to search for or enter a separate referral code.
If you already have a Prüvit Partner or referrer you're working with, I recommend continuing to work with that person.
Can I Try Prüvit K1 Before Buying a Larger Supply?
Yes. If you're not ready to purchase a larger supply of K1, I offer smaller K1 trial options through MrKetosis.com/shop. It's an easy way to try K1 without starting with a larger order, and qualifying U.S. orders from my shop include free shipping. Trial options and flavors can change based on availability, so visit my trial shop to see what's currently available.
Interested in the Prüvit Partner Opportunity?
Some people discover Prüvit because they're interested in trying K1. Others become interested in sharing the products and building a business as a Prüvit Partner.
I've been involved with Prüvit for many years, and if you're interested in learning about the Partner side of Prüvit, I've put together additional information to help you understand how it works, what to consider and how to get started.
Becoming a Prüvit Partner isn't required to use or purchase K1. The Partner opportunity is simply an option for people who are interested in sharing Prüvit products and potentially building a business around them.
