(Last Updated on November 9, 2022)
A ketogenic diet has been the most popular weight loss program for years.
It is a high-fat, low-fat diet usually associated with several health benefits including weight loss, better cognitive performance, improved exercises and reduced appetite.
The body forms ketones (molecules) during fat breakdown in low amounts.
But when, these levels go up, primarily due to starvation, ketogenic diet and prolonged fasting, the body goes through ketosis.
Here the body burns fat proficiently for energy.
Due to the popularity of the diet, several keto-friendly dietary products have surfaced.
They promise to offer the benefits of a ketogenic diet without following one.
Pruvit Keto OS NAT is one of them; it claims to take you into ketosis.
But how unique is it from the rest?
In this Pruvit Keto OS NAT review, we will reveal the ingredients used, how it works, any side effects present, if it is a scam and its pros and cons.

How Does Pruvit Keto OS Work
The secret behind this supplement is Beta-Hydroxybutyrate ( BHB Salt).
It is an exogenous ketone body that supports metabolising fat into body energy without carbohydrates.
The body produces a lot of BHB when the body goes into ketosis.
Pruvit Keto OS NAT uses water-soluble BHB increasing absorption in the body system within an hour.
They increase ketone levels that support weight loss.
Additionally, Pruvit Keto OS NAT increases appetite suppression and reduces your urge to snack.
This supports fat loss.
The proprietary blends improve cognitive function and increase mental clarity.

Pruvit Keto OS Side Effects
Pruvit Keto OS NAT is probably safe in healthy people but only when taken for a short period.
There is less information on long term effects.
However, here are some things to consider:
Research shows that individuals who go on a low carb diet may develop Atkins Flu characterised by headaches, irritability, heart palpitation, diarrhoea/constipation, dizziness and fatigue.
Fluid loss may occur if you combine a ketogenic diet with this supplement.
This may come from the breakdown of carbohydrates stored in muscles (glycogen).
Some users are also likely to experience diuretic effects, mild headaches and nausea due to the presence of caffeine.
Consult your physician before taking this exogenous ketogenic supplement if you have:
- Kidney problems
- High blood pressure
- Heart disease

The manufacturer cautions against using the supplement if you are pregnant, nursing or having a pre-existing medication condition.

Pruvit Keto OS Reviews & Complaints
Pruvit Keto OS NAT has not received much customer reviews because it is their new upgraded formula.
However, it is on both receiving ends of favourable and unfavourable feedback.
Here are some reviews on Amazon.
Let’s start with the positive ones.
Mark used the Maui Punch Flavor of Keto OS NAT.
This is what he wrote on Amazon:
I have used this several times, and I’ve lost weight quick every time. The flavour is pretty good, but it is too expensive to use regularly. I usually buy it to help speed up my diet after I’ve come off a carb binge for a week or two. No problems are shedding the weight when I use this.
Christin Perry took the Maui Punch flavour charged and was pretty happy with it.
She wrote on Amazon.
I have had very low energy, and I have ADHD anxiety, depression, and always feeling really overwhelmed before taking Keto os NAT […] product has made me feel so much better. I have had way more energy; my anxiety depression was gone I didn’t feel so overwhelmed I felt like I can conquer anything and very feel extremely confident in myself and also very focused, and also it decreased my appetite […] I highly recommend trying this product!!!!!
What about the negative reviews?
An Amazon customer who took Heart Tart flavour had this to say.
Though it’s an excellent product, it’s entirely too sweet. I squeeze a lemon in my drink to counteract the overly sweet taste, and it’s still too sweet. The stevia is overkill.
Nancy was disappointed after taking Heart Tart flavour.
She wrote on Amazon:
Expensive and had zero effect. Save your money.
Rich writes on supplementclarity.com:
I tried pruvit ketones for a month. I didn’t notice any decrease in appetite or body weight.

Pruvit Keto OS Pros & Cons
Pruvit Keto OS Review: Final Words
Using exogenous ketones has become a rising trend lately.
Pruvit Keto OS NAT improves energy levels, increases athletic performance, increase clarity and focus, and suppresses appetite.
There is some scientific evidence that supports the above benefits of using exogenous ketones.
But these studies are limited.
It is an ideal supplement for those looking to reach ketosis faster, boost performance, lose weight and increase mental performance.
We noted that the supplement contains a high amount of sodium.
Therefore you should limit high amounts of sodium in your meals since it may result in Hypernatremia.
Hypernatremia is characterised by increased thirst, bleeding in the brain, muscle twitching, confusion, loss of appetite and weakness.
Finally, Pruvit Keto OS NAT is an excellent fat loss supplement, but it is expensive.
Moreover, there are no clinical trials that support their claims.
Therefore we cannot tell if they work like a ketogenic diet.
