Within 60 minutes of taking the Keto OS pills, according to Prüvit, users can enter a nutritional ketosis condition.

This might appeal to people put off by how much effort and commitment it takes to follow a ketogenic diet and bring the body into a state of ketosis, which can take weeks.

Eighty percent fat, 15 percent protein, and 5 percent carbs make up the standard ketogenic diet. For an extended period, it can be challenging to adhere to.

As well as, exogenous ketone supplements were developed to give patients a faster route to ketosis and its benefits without requiring them to fast or adhere to a strict diet.

Contrary to the gradual increase in blood ketones brought on by a ketogenic diet, taking an exogenous ketone supplement like Keto OS causes a quick rise in blood ketones (5Trusted Source).


*All individuals are unique. Your results can and will vary.

The body transforms beta-hydroxybutyrate into an efficient energy source after ingestion by absorbing it into the bloodstream.

Exogenous ketones are appealing because they increase ketone levels even in people not in ketosis when they first take them.

According to some claims, achieving nutritional ketosis with supplements can have similar advantages to achieving it through a ketogenic diet or fasting. Weight loss, higher vitality, and improved mental clarity are among these advantages.

We Pruvit Keto Os – Our Take

Our team had been using the Pruvit Keto-OS for three months in our in house team. We were all skeptical at first, but we were willing to give it a try. As we all heard about the benefits of ketosis, and we were hoping that the Keto-OS would help us to reach ketosis faster and more easily.

To our surprise, the Keto-OS worked even better than we had hoped. Within a few weeks, we were all feeling more energized and focused. We were also losing weight, and our overall health was improving. However, we also experienced some negative side effects, such as nausea, diarrhea, and headaches.

One of the best things about the Keto-OS was that it didn’t make us feel hungry. We were able to eat less food and still feel satisfied. This made it much easier to stick to a keto diet. However, we also found that the Keto-OS was expensive, and it was not always easy to find.

After three months, we were all so happy with the results of the Keto-OS that we decided to continue using it. We are all convinced that it has helped us to improve our health and well-being, but we also know that it is not a miracle cure. There are some negative side effects, and it can be expensive. However, we believe that the benefits outweigh the risks.

One of the team members, John, had been struggling with his weight for years. He had tried everything, but nothing seemed to work. After starting the Keto-OS, he lost 20 pounds in the first month. He was so happy with the results that he continued using the Keto-OS, and he has now lost a total of 50 pounds. However, he also experienced some side effects, such as nausea and diarrhea.

Another team member, Mary, had been diagnosed with diabetes. She was taking medication, but her blood sugar levels were still not under control. After starting the Keto-OS, her blood sugar levels normalized, and she was able to stop taking medication. However, she also experienced some side effects, such as headaches and fatigue.

Overall, we are all very happy with the results of the Keto-OS. We believe that it has helped us to improve our health and well-being, even though it has not been without some negative side effects. We would definitely recommend it to anyone who is looking for a natural way to lose weight, improve their energy levels, and overall health. However, we would also caution them to be aware of the potential side effects and to talk to their doctor before starting.

Pros and Cons Of Pruvit Keto Os


  • Pruvit Keto Os available on Amazon
  • Quickly enter ketosis
  • Strengthen athletic performance and energy
  • Helps in reducing appetite

Side Effects From Pruvit Keto-OS

Constipation, diarrhea, stomach pain, and gas are some of the most frequent side effects of exogenous ketone supplementation.

Bad breath – Acetone, one of the ketone bodies, is produced in such large amounts during the first week of the ketogenic diet that it can be exhaled with each breath. This might also happen if you’ve taken exogenous ketones.

Cost: For “best performance,” Prüvit advises taking two servings of Keto OS NAT daily. This translates to an additional $91 taken from your bank account each week in exchange for a momentary increase in ketone levels.

Could result in hypoglycemia – Ketone supplements can lower blood sugar levels. Therefore, diabetics need to speak with their doctor before using.
Could lead to disordered eating — Pruvit promotes a healthy keto or low carb diet, but without any solid proof to back up their claims, their marketing and educational materials also stress the need for a rapid fix for ketosis and a magical cure for problems with fat loss.

Consequently, adopting their supplement approach can lead to the same disordered eating patterns we frequently attempt to avoid by eating low carb.

Real Consumer Reviews On Pruvit Keto-OS

“Don’t waste your time.” – Dom Tisher – Soldier

Keto OS worked for both my wife and me. I was overweight, suffered from severe headaches, and napped like it was my full-time job. It helped me feel more energized and clear-headed. I was addicted to pain meds and sleep aids, which improved those things. It works but doesn’t do the work for everyone.

Pruvit Keto-OS Review – Final Words

It contain a substance that has had some success in weight reduction products of this type in the past. However, due to a lack of knowledge of the ingredients and producer, it is uncertain how efficient the outcome would be and how safe it would be. Consumers should be cautious of any free trials linked to an auto-ship program, as they can be difficult to cancel and expensive.

It’s also worth noting that Pruvit Keto-OS appears to have no guarantee or return policy. However, the advantages of KETO/OS are far less certain than the disadvantages. There is currently no study on KETO/OS.

Therefore, it is unlikely to be a trustworthy strategy to cheat your way to long-lasting keto outcomes. As well as for better results, you can go through Phen24, which is a better weight loss supplement having not any side effects and can be consumed for the long term.

Better solutions are available, and while they may necessitate more investigation, you will reap greater overall rewards.
