Keto Reboot Claims

The makers of the 60-hour Keto Reboot claim that their product will:

  • Control your cravings
  • Maximize your energy
  • Protect your muscles
  • Hold you accountable for your results

Keto Reboot Ingredients

Pruvit Keto Reboot includes four different products:

  • Keto OS NAT
  • Better Broth
  • Signal OS
  • Keto OS Pro
  • Mito Plex

Keto OS Max

The Pruvit Keto Reboot comes with four Keto OS Max drink packets. Keto OS stands for keto operating system. Pruvit claims that the Keto OS Max formula is designed to maximize brain power, increase performance, and push you past your mental and physical limitations. Keto OS Max is supposed to taste like raspberry lemonade and includes the following ingredients:

  • Beta-hydroxybutyrate
  • Fermented leucine
  • L-Taurine
  • AC-11


Beta-hydroxybutyrate is a ketone body commonly used in ketogenic diet supplements to increase the amount of BHB in the bloodstream, according to Nutrition & Metabolism. The manufacturers of these supplements purport that supplementing ketone bodies will force dieters to enter a state of ketosis.


L-taurine is an ingredient commonly found in energy drinks. Research, as published in Molecular Vision, shows taurine is found in abundance in the brain and muscle tissues – though the whole purpose has not yet been discovered.


AC-11 is an extract commonly used in dietary supplements and skincare products, according to the Dermatology Online Journal.

Better Broth

The Better Broth is the only thing you’ll be eating for 60 hours, so hopefully, you like it. This chicken and beef bone broth comes in thyme and salted caramel flavors and includes the following ingredients:

  • Beta-hydroxybutyrate
  • Fermented L-leucine
  • Type II collagen peptides
  • AC-11

Type II collagen

According to research in PLoS One, collagen is a peptide responsible for reducing inflammation in the human body.

Keto Kalm

Keto Kalm is a tea mix that can be taken during the day to “evoke a blissful feeling of peace.” It can also be taken before you go to bed for a more restful sleep. You’ll receive three tea satchels; one is chocolate, and two are caramel apple. Keto Kalm is made from the following ingredients:

  • Beta-hydroxybutyrate
  • L-HICA
  • Roobios tea
  • 5-HTP
  • AC-11
  • Zinc Gluconate


According to Wikipedia, L-HICA is a metabolite of leucine that is often used as a muscle-building supplement. L-HICA has been added to the Pruvit Keto Reboot to prevent muscles from breaking down during the fasting period.

Rooibos tea

Originating in South Africa, Rooibos tea is a caffeine-free tea that is often taken with milk and lemon.


5-HTP, or Hydroxy-Tryptophane, is a natural treatment for depression. There is early research to suggest 5-HTP is an effective appetite suppressant, but more research is needed.

Signal OS

Pruvit claims that Signal OS contains powerful bioactive ingredients that help repair DNA, improve concentration and boost your immune system. You’ll receive ten capsules of Signal OS that contain the following ingredients:

  • Vitamin B12
  • AC-11
  • Eleutherococcus senticosus extract
  • Sodium
  • Reishi mushroom
  • BioPerine

Eleutherococcus senticosus extract

Eleutherococcus senticosus extract is an herb that acts as an adaptogen, improving workout potential, decreasing stress, and benefitting the immune system. It’s also been shown to improve memory, according to Nutrients.

Reishi mushroom

Reishi mushrooms are found in Asia and are commonly used in Eastern medicine.


Derived from black pepper, BioPerine helps the human body absorb other nutrients.

Does Keto Reboot Work?

Will you lose weight with Pruvit Keto Reboot? Yes. Anytime you fast for 60 hours, you will lose weight. The problem is that you’ll have to maintain a strict ketogenic diet after the fast to see any real results.


Keto Reboot Benefits and Results

Several Keto Reboot customers took to Amazon and Facebook to call the 60-hour Keto Reboot the worst 60 hours of their life. There are no testimonials on the official Pruvit website, but 100 percent of Amazon reviewers rated this program 4/5 stars.

Details on Keto Reboot and Weight Loss

One study published in the International Journal of Obesity found that intermittent fasting may aid in weight loss. However, this fasting practice extends nowhere near as long as 60 hours, which can be considered dangerous.

Additionally, more research must happen to determine if fasting leads to long-term weight loss and/or causes weight regain in the future, according to Cureus


How to Take Keto Reboot

For the best results, you’ll need to adhere to the Keto Reboot schedule and start fasting on Sunday evening. The Keto Reboot directions on the Pruvit website say to take two Signal OS capsules with water twice a day. The Keto Reboot instructions recommend drinking Keto OS Max in the afternoon and having the Better Broth for dinner. The Keto Reboot directions also say that you can drink Keto Kalm during the day or before bed.

For the 60-hour duration of the Keto Reboot Camp, you’ll have to fast. You can’t eat anything, and you can only drink water. Drink at least one gallon a day. Staying hydrated is incredibly important. Pruvit Keto Reboot has high salt content, making dehydration slightly more likely.


How Much Does Keto Reboot Cost?

The Keto Reboot kit costs $110 on Amazon. The Pruvit website lists the price at $79.

This kit includes everything you need to complete one 60-hour Keto Reboot fast.

What Users Are Saying

What Users Are Saying

“Really works! Tastes fine! Lost 7lbs! I read some reviews and they said it tasted bad and didn’t work. I have no idea what they are talking about. Maybe these reviewers have never been on a diet?!?!”

“The Gastrointestinal Distress is REAL! – I’m no stranger to intermittent fasting and was super geared up to do this, BUT… I’m fairly certain that in all of my 48 years on this planet I’ve NEVER tasted anything as gross as the broth! Both flavors!! I’m also more than a little convinced that all of my coworkers have taken a hit out on me for how I have completely DESTROYED the bathroom at work because lemme tell ya, the gastrointestinal side effects of this remarkable journey are no joke! Hats off to Pruvitt for a clever marketing scheme to expose people to a chunk of their products and get rid of what I can only conclude was a HUGE back stock of disgusting broth packets that Nobody wanted.”

“Need to improve the bone broth flavor it was not great! – Just finished my 60 hours, and I did lose 5 lbs. Great products in this package, but I will be honest the last day was hard for me I wanted to break the fast all day but I did not and I did not like the taste of the bone broth at all but forced it down and the only other negative was everyone says they got the best sleep, I didn’t sleep well at all. But I am glad I did it, but I will be only doing 20 hour fast from now on with no bone broth! Good luck to everyone, you will get results, my ketone level is 3.00 so I happy about that! Oh the raspberry lemon is awesome!”

  • No problems for me with the reboot
    Rebecca (Verified Purchase)

    I did the Keto Reboot for the first time last weekend and lost 7 lbs. I felt fine the entire time, with the exception of some night nausea. To overcome this, I drank a shot of pickle juice and was perfectly fine. I did not miss the food, I was able to function every day and felt good. I will be doing it again.

  • Keto Reboot yuck
    Anonymous (Verified Purchase)

    We did not get the flavors of tea or broth that everyone was talking about…spash is horrible! If you are sensitive or have an adversion to you’ll hate this..French onion bone broth was ok but the rest tasted awful! & We couldn’t get questions answered, there’s is no customer service that I could find….we would not spend the money again for this! I feel more bloated than before..

  • Danielle (Verified Purchase)

    I love the reboot. It helps reduce carb cravings after the 60 hour fast. It is intended to work with an ongoing Keto diet and exercise program. I also use their ketones packets outside of the fast. I have lost over 40 pounds over 6 months. You can’t expect the reboot to work on its own without follow up. That’s ridiculous.
