Sletrokor Review

Sletrokor is a diet pill made in the USA by 18Nutrition.

The company also markets a number of other weight management products including a meal replacement shake called 18Shake.

The company normally builds a dedicated website to promote each of the products it brings to market.

Sletrokor is no exception.

Although Sletrokor’s website provides a decent amount of information about what the product is supposed to do and how the ingredients are intended to help, the marketing material makes the product sound a lot better than it is.

For one thing, the formulation contains some questionable ingredients. It contains respected fruit extract as well, so it’s not all bad. However, no inclusion rates are provided.

Evaluating the merits of a product isn’t easy when you don’t know if it contains enough of the better ingredients.

It’s also worth mentioning, customer reviews (and critical reviews by industry experts) for this product are not very good and the money back guarantee is not what it seems.

Sletrokor already has a pretty bad rep. Let’s take a closer look at the product and see if it deserves all the bad press.

What Is Sletrokor?

Sletrokor is a capsule-type supplement. There is no sexual bias as far as the marketing goes. It’s for any man or woman who wants to lose weight.


18Nutrition claims the product “may” provide help in the following areas:

  • Appetite suppression
  • Blood pressure reduction
  • Lowering cholesterol
  • Boosting the metabolism
  • Aiding digestion
  • Enhancing the immune system
  • Decreasing leptin levels
  • Increasing serotonin levels

Who Is It For?

Sletrokor is for healthy adults who need help to lose weight. 18Nutrition say the formulation is unsuitable for children or anyone under the age of 18.

People who have existing medical conditions will need to address any questions they may have to a doctor. This information is imparted in the site small-print and it’s very easy to miss.

It goes without saying, Sletrokor should not be used by women who are pregnant or nursing a child.

Manufacturer Credibility

Complaints about the company have been lodged at a number of internet complaint sites including ScamGuard and the Ripoff Report.

The complaint on Ripoff Report from a woman whose card was hit with an unexpected charge of $300 makes particularly interesting reading.

Some of the people complaining say the product made them ill. Others allege the company increased the size of the order and billed their cards accordingly.

Still others have complaints about the money back guarantee.

In fairness to the company I cannot think one single supplement manufacturer who hasn’t been on the receiving end of at least one complaint filed from a disgruntled customer.

Intended Method of Action

If the formulation can fulfil the promise of appetite suppression it will help people to eat less food without feeling hungry.

Should it also be able to boost the metabolism, it will cause people who use it to begin burning calories faster.

Serotonin is the happiness hormone. It affects the mood. On top of this, boosting serotonin may also provide a hunger-reducing effect.

Leptin ghrelin

Leptin is one of two hunger hormones. The other one is ghrelin. When ghrelin increases it triggers the urge to eat. Leptin controls ghrelin. It’s a body’s appetite suppressing hormone.

So, if Sletrokor is capable of reducing leptin, it’s a diet pill feature you really don’t want.

None of the other promised benefits are directly associated with weight loss.

Ingredient Profile

Two capsules provide 1500mg dose of a proprietary blend.

The blend contains unspecified quantities of the following seven ingredients:

  • Garcinia Cambogia
  • Phaseo Vulgaris
  • Chitosan
  • Cider Vinegar
  • Gymnema Sylvestre
  • Cascara Sagrada
  • Aloe Vera (200:1 extract)

Credible Inclusions

Only four of the ingredients have any credibility as diet pill inclusions:

  1. Garcinia Cambogia

The garcinia cambogia extracts used in diet pills are taken from the rind of the fruit. The active component is a chemical called hydroxycitric acid (HCA).

Garcinia cambogia

HCA mainly supports weight loss by providing appetite control, but it also appears to interfere with the body’s ability to store fat.

Garcinia cambogia is a good ingredient, but the formulation may not contain enough and there’s another problem. Garcinia cambogia only works if the extract provides at least 60% HCA. 18Nutrition are using a version that is only 50% HCA.

  1. Phaseo Vulgaris

This ingredient is more commonly known as white kidney bean and it’s a respected carb blocker.

white Kidney bean

Phaseo vulgaris has the ability to suppress the activity of the digestive enzyme amylase. It’s the enzyme responsible for breaking down carbohydrate.

By weakening amylase, phaseo vulgaris causes a percentage of any carbohydrate that has been consumed to pass through the body undigested. Food that is not digested does not release any calories.

  1. Chitosan

Chitosan is a fat blocker. It binds with dietary fat and shields it from digestion.

The most common type is taken from the shells of crabs and other marine crustaceans. It’s not suitable for people who have seafood allergies or for vegetarians.


There is also a second type of chitosan that has a fungal origin, but 18Nutrition do not say which type is in use.

  1. Cider Vinegar

Consuming apple cider vinegar has long been favoured as a good way to lose weight and scientific research proves its worth. It’s also been linked to numerous other health benefits but, again, does the formulation contain enough?

Apple Cider Vinegar

Less Credible Inclusions

Gymnema Sylvestre 

Gymnema sylvestre is a perennial woody vine. Extracts from the plant are sometimes used as a cholesterol management aid.

The ingredient appears to support weight loss when it is combined with HCA, niacin and chromium, but the last two ingredients are not present in the Sletrokor formulation.

Cascara Sagrada + Aloe Vera

Both the ingredients are laxatives and neither one is normally linked with fat loss. When laxatives are added to diet pills it can cause people to believe they have lost weight when they have not.

Genuine weight loss is fat loss. That’s not the same as walking around with intestines that are emptier than normal.

Recommended Dosage and Usage Considerations

The capsules are taken with water and the dose is four capsules per day, taken as two separate doses. The doses should be taken before meals and it’s important never to exceed four capsules in any 24-hour period.

18Nutrition also suggests customers who buy Sletrokor buy one of their other products as well. It’s a metabolism booster called Vitakor and the company say it increases the effectiveness of Sletrokor.

Buying two products instead of one will also increase the company’s profits along with the customers’ expense. This is an expensive option to start with yet 18Nutriton appear to be suggesting it may not be strong enough to go it alone.

Sletrokor Side Effects and Interactions

18Nutriton don’t mention any side effects use of their product may entail, but some customers state using the product made them feel unwell.

Customers who have delicate stomachs should certainly think about giving this one a miss. Aloe vera is a laxative and using any form of laxative for two weeks or more is unwise.

Despite the fact that 18Nutrition proclaim the ingredient boosts the metabolism, a scientific review of the capabilities of aloe vera suggests this is not so.

The researchers state the evidence shows aloe vera offers the greatest potential as a laxative. They also point out its use may involve “considerable risks”.

Cascara sagrada is a laxative as well. That makes it a poor option for people with a history of stomach or intestinal problems. The ingredient also reacts badly with certain medications. In fact, once respected source provides a list of more than 250 cascara sagrada Drug Interactions.

Chitosan is a fat blocker. Phaseo Vulgaris blocks carbs. Both ingredients cause the intestines to become home to undigested food. Again, this can cause problems for anyone with a sensitive stomach.

Throw a couple of laxatives into the equation and the chances of adverse issues can only increase.

Sletroker is not a product you should be thinking of using without speaking to your doctor about it first.

Sletroker Customer Reviews

Sletroker customer reviews are mixed.

A few average comments read:

“I do not like this company. When I placed an order my card was charged but I received no confirmation of the order and the package never arrived. It’s now been a month. I tried calling the company but nobody picked up the phone. They just take the money and run.”

“Great product, I lost a tones of weigh” (sic)

“I’ve lost a little weight, but it may be due to my new exercise routine and it’s been an uphill battle all the way because Sletrokor did not help control my appetite at all.”

“Don’t work at all. Very disappointing experience.” 

“Zero appetite suppression and no weight loss. I used it for a month without any results at all. All it did was give me headaches. Total waste of money.”

Where to Buy Sletrokor

Although 18Nutrition previously sold the product via Amazon as well, this is no longer the case. If you want to buy it now the 18Nutrtion website is the only place to go.

The site has details of a “limited time offer” that allows customers to buy Sletroker at the discounted price of $35.99 per bottle.

This offer is anything but limited. The company has been making the same offer for a very long time and it’s the first thing site visitors see when they land on the page.

The details provided are also misleading, but customers have to provide their full contact details, including a telephone number, before they can visit the order page.

The order page shows a single bottle of Sletrokor actually costs $59.99. There’s also a further charge of $5.99 to cover shipping.

Customers cam only lock-in the promised price of $35.99 per bottle by ordering three bottles of Sletroker. This option is pre-selected when customers land on the page.

Money Back Guarantee

18Nutriton state Sletrokor has a 30-day money back guarantee. The company back this up with the promise “Get results with Sletrokor or your money back!”.

However, site visitors who visit the page that provides full details of the “guarantee” will find things are not as they seem.

The page states: “If you are dissatisfied with our product, you can receive a full refund if you return your unopened items within 30 days of delivery.”

The page also lays it out in no uncertain terms: “Please note that we accept unopened bottles only”.

This is a refund policy, not a money back guarantee. Furthermore, even customers who do manage to qualify for a refund will still be out of pocket because 18Nutrition’s terms and conditions page states refunds are less a 20% restocking fee.

Final Thoughts and Recommendations

If the formulation contains enough of the more credible ingredients, Sletrokor may offer some level of weight loss support. However, the fact that the majority of customer reviews are so poor suggests that it does not.

The other problem with this product is the price. It’s too high and the lack of a genuine money back guarantee throws a further spanner into the works. It’s simply not a good investment.

Then there’s the fact that 18Nutrition appear to be using some very questionable marketing techniques. Of course, the building of fake review sites is nothing compared with the bad experience some customers complain about.

There are so many more credible alternatives available, it’s amazing anyone has chosen to buy Sletrokor instead. Even if the product does not work, something about the marketing spiel obviously does.
