Many claim that Purefit KETO could be one of the best supplements available on the market for people eating a ketogenic diet as they try to lose pounds. 

Is it true though?

And how exactly does the ketogenic diet work? One expert summed it up nicely without getting too sciencey:

The ketogenic diet is a high fat diet with low carbohydrate and moderate protein content. Carbohydrate is depleted to provide an alternative fuel source, known as ketones, to the brain. The body converts from burning carbohydrates to burning fats, known as ketosis.

What is Purefit KETO?

According to the manufacturers, Purefit KETO uses a natural formula to get those ketones burning in your body and encourage weight loss.

Purefit KETO features a gluten-free formula which is also 100% vegan so it’s suitable for people with a wide range of eating habits.

These pills contain a blend of supplements which encourage ketosis, such as calcium BHB, sodium BHB, and potassium BHB.

These pills as a weight loss supplement might work for you, but only if you have the mindset and determination to go with this special nutritional formula.

But even then, we're not completely convinced that this product works for everyone.

Purefit KETO Benefits

Purefit KETO claims to use natural appetite suppressants in the form of BHB - meaning that you’ll feel fuller longer, helping you to eat less on the demanding low-carb keto eating plan. 

These products might also give you a small burst of energy, helping you to sustain yourself throughout the day while your body grows accustomed to burning ketones as an energy source.

The diet supplements can also be used for other nutrition plans too, including the Paleo diet and Intermittent Fasting, with the exogenous ketones helping you to beat hunger and lose weight. (1)

The price of the product could also be a selling point and people in the Purefit KETO reviews are certainly not complaining about that.


  • 100% vegan and gluten-free products
  • Natural fat burning and appetite suppressing formula – burn fat and feel fuller
  • Source of exogenous ketones – helps to encourage ketosis
  • Natural ingredients with multiple health benefits & fitness results

Purefit KETO Side Effects

Of course, like any diet supplements, there are side effects which need to be taken into consideration with these pills. And, there are very few to report.

Some people report feeling very sluggish and have low energy when taking Purefit KETO, but this could simply be due to the low-carb high-fat diet that they’re eating to encourage ketosis.

Furthermore, some people report that the product was not a miracle weight loss solution as it seems to be marketed. 

side effects

However, most people do agree that the product can help to control cravings and suppress your appetite, making it easier to stay slim by eating a healthy eating habits and not scoffing a ton of food on a whim.

Overall, there are few side effects to note about this product, and many of the downsides can be attributed to the downsides of the keto diet itself rather than any side effects of Purefit.


  • Some users report fatigue and sluggishness
  • Not a “miracle weight loss” product as the makers suggest

Purefit KETO Ingredients

Purefit Keto contains sodium BHB, calcium BHB, and potassium BHB as its active ingredients:

  • ​Sodium BHB - Sodium BHB (which stands for Sodium Beta Hydroxybutyrate) is a natural compound which comes from stable mineral salts. These mineral salts are a different compound to the table salt we use for food, which is primarily sodium chloride. Sodium BHB is considered to be a “ketone body” and as such it helps your body to produce energy when glucose is not present. Sodium BHB is essential if you want to burn fat during a workout.
  • ​Calcium BHB - Calcium BHB, along with other “BHB” ingredients, is Generally Recognized As Safe (GRAS) by the FDA in the United States, so you can rest assured that you’re not putting your body in harm’s way with it. (2) Calcium BHB is one of the most common naturally-occurring mineral salts which can be used as a “ketone body”  during an intense workout.  This ingredient is popular with people following the keto diet, paleo diet, and very low-carb diets. 
  • ​Potassium BHB - Another one of the more common BHB mineral salts, potassium BHB helps to fuel your body’s natural metabolic functioning and energy consumption when you’re going through extended periods of a keto diet with low intakes of carbohydrate. It has also been linked to remedying the dreaded  "keto flu" which can plague inexperienced keto dieters. (3) Just be sure to take the recommended dose, as too-high potassium levels can lead to numerous health problems. (4)

How Much Does Purefit KETO Cost?

For the standard 30-day bottle of Purefit KETO, you can expect to pay around $37.99 on Amazon and similar retailers.

This standard bottle contains 60 pills, meaning you pay around $0.63 for each pill.

If buying multiple Purefit KETO weight loss products at once, you may be able to take advantage of discounts.

Is Purefit KETO legitimate?

Purefit KETO is legitimate, as a weight loss product which we tried and tested ourselves. The product mimics the natural process of ketosis in the body, helping you to lose weight while eating a high-fat keto diet. We noticed considerable results and benefits after using this supplement.

But as a company, we're not too sure about that. Some people have claimed that they have been scammed buying through the website.

Personally, we haven't found evidence of it but a few people saying that they were charged a few times is enough for us to be a bit skeptical as well.

When was Purefit KETO on Shark Tank?

Shark Tank

Purefit Keto was probably not on Shark Tank at all, as no footage of its TV pitch appears to be available online or in archives. 

There are some suggestions that the Purefit Keto Shark Tank story was fabricated for publicity and that they were never featured on the popular business investment show. For example, according to the Better Business Bureau, the product was never featured on the show at all. (5) They state in a report:

“BBB has confirmed that the images appearing on PureFit KETO's website were taken from a separate Shank Tank episode that does not mention PureFit KETO. Internal research has been unable to locate any episodes of Shark Tank that featured PureFit KETO”.

Given the amount of controversy and doubt there is around this topic, it’s pretty safe to assume that Purefit Keto was never featured on Shark Tank. I mean, for a multi-million-dollar TV show with a huge audience, you’d think there’d be some footage, right?

Some sources have theorized that the folks at Purefit Keto used a shady fly-by-night marketing company for their early promotion, suggesting that the marketing firm published images on the Purefit Keto website which insinuate that the product was featured on the show.

So no, it seems that the product was never featured on Shark Tank despite what earlier promotional material may have suggested.

Purefit KETO Results: Before and After

So, I wanted to see what other people's experience was with this product. Here's Steven's results from consistently using Purefit KETO - he lost a lot of weight!

And here's Cam talking about his experience with the pills and how he recommends it:

Purefit KETO: Does It Really Work?

Having tried it for a few weeks, we can say that it is a decent product but there are other factors involved that makes us want to back out.

But as a weight loss supplement alone, this supplement may help you lose weight, suppress your hunger, and increase metabolic rate, which can make it easier for you to drop the pounds.

It is an exogenous ketones after all.

If you are really keen on getting in on this product, you can check it out on the right.

But take it from us, there are better options out there that do not have "scam" tied to its name.
