Sletrokor Review

People Who Viewed Sletrokor Supplement Also Viewed Trim Down Club.

Sletrokor markets itself as an appetite suppressant and “easy weight loss.” It’s a mixture of Garcinia cambogia, Aloe Vera, Gymnema sylvestre—all fairly well known in the diet supplements market—and something I wasn’t as familiar with, Cascara sagrada. We’ll check these ingredients, and the rest of the list, out in a moment. But what’s oh-so-familiar is this particular pitch:  

What was discovered was not only unique but also unlike any other ingredient.

One of the key ingredients found in Sletrokor, Garcinia Cambogia, was tested for its effectiveness. What was discovered was not only unique but also unlike any other ingredient. … this landmark ingredient [was tested] on 30 obese subjects who lost 14 pounds in just 8 weeks. The kicker? All this came without diet and exercise. [1] 

18Nutrition produces this supplement. The office headquarters address is: 600 W 9th Street, Suite 611 Los Angeles, CA 90015. Their customer service number is 800-614-1820. [2] 

“…There was no Better Business Bureau profile for 18 Nutrition”

There was no Better Business Bureau profile for 18 Nutrition, but there was one under 18 Shake, one of their other products. Opened in 2015, the profile carries an F rating for failure to respond to customer complaints filed with the BBB. [3] 

When I called in to their customer service line, they referred to their office as 18 Nutrition, not Sletrokor, and they claimed that you can only purchase the product online, as it has “sold out” in the stores.  

A 30-capsule bottle (at 2 capsules before each meal, this comes out to a 5-day supply) costs an eye-watering $58.99 plus shipping and handling—unless, of course, you buy their “best seller deal”: five bottles for $35.99 each. That’s a 30-day supply for $179.95 plus shipping and handling. One hundred eighty dollars for a month of pills. [1] 

The company boasts a 100% money back guarantee, but:  

We have 30 days return policy for our products. Please note that we accept unopened bottles only. In order to process Your refund, You must supply 18Nutrition with your name, order ID and delivery address. If You provide us with insufficient or incorrect information, refund will be delayed. In order to qualify for a refund, you must provide us all the information we ask for, and comply with all other terms specified on this website for such purpose. To claim your refund under this guarantee, please contact the support team from the Contact Us page. Restocking fee may apply[4] (emphasis added) 

the return policy is useless unless you buy multiple bottles up front

So how are you supposed to try out the product if you can’t even open it without risk of not getting your money back? Reality check: the return policy is useless unless you buy multiple bottles up front—which they’re hoping you do. And they’ll likely charge you for putting their product back on their shelves. 

And if you go into their Terms and Conditions, you find 30 days may not be 30 days after all: 

We have 15 days return policy for our products. Please note that we accept unopened bottles only. [5] (emphasis added) 

They may not be one of those negative-option autoship scams, but there’s plenty of flashing red warning lights going on for me. 

Sletrokor Claims 

Nothing especially new in the claims department. 

Easy weight loss is Sletrokor’s calling, all in a completely natural combination of ingredients. 

Sletrokor provides use by: supports healthy cholesterol; boosts serotonin; reduces hunger; enhances healthy metabolism; aids reduced blood pressure; increases immune function; shoots down leptin ratio. 

It all comes down to HCA or Hydroxycitric Acid which is found in spades in Sletrokor. The Garcinia Cambogia provides an ample amount which has been tested to show an increase in overall mood thru the increase of serotonin.

HCA also limits lyase production. What lyase does is work inside the body to destroy chemical bonds. These same bonds stop our natural fat burning from occurring. An added benefit is not only does HCA improve fat burning but it manages the stress hormone cortisol and winds down the bad LDL cholesterol, while supporting healthy triglycerides. [1] 

Sletrokor Ingredients 

Sletrokor is nice enough to post their label on their site, which is refreshing. 

“…Sletrokor isn’t for women who are pregnant or nursing, nor for children under 18”

Proprietary Blend, 1500 mg: Legume Protein Concentrate (Phaseo vulgaris—white kidney bean); Chitosan; Cider Vinegar (as powder); Garcinia Cambogia (as 50 percent ext.); Gymnema Sylvestre (As herb powder); Cascara Sagrada (As herb powder); Aloe Vera (200:1 extract). 

There is a shellfish allergy warning because of “shellfish derivatives”—this would be the chitosan—and a caution that Sletrokor isn’t for women who are pregnant or nursing, nor for children under 18. [6] 

The Science (or Lack Thereof) Behind Sletrokor 

There have been multiple studies done on Garcinia cambogia, and its ability to curb the appetite and promote fat loss. The results have so far been consistent: while no miracle pill, G. cambogia serves as a mild-to-moderate appetite suppressant, and may inhibit an enzyme which converts carbohydrates to fat (leaving them carbs longer so the body can burn through them rather than store them), but so far its effectiveness seems to be limited to a 12-week period. [7]  

while no miracle pill, G. cambogia serves as a mild-to-moderate appetite suppressant

Note: the most effective Garcinia supplements with the fewest side effects are those which are single-ingredient—containing only G. cambogia. And the maximum safe dosage tested to date is 2800 mg per day. [8] 

Aloe Vera is well known for its effectiveness on skin rashes like psoriasis, and there’s good evidence it can treat dandruff, but according to the Mayo Clinic, in terms of weight loss it really only seems to offer mild laxative effects. [9] 

WebMD lists Gymnema sylvestre as a shrub that grows in India and Africa; the leaves have been used for thousands of years as a treatment for diabetes. The Hindu word for gymnema—gurmar—means “sugar destroyer.” And while some animal studies found that gymnema may reduce weight and lower triglycerides, there’s been no research to see if similar results occur in humans. [10] 

“…there’s no real evidence it does anything for weight loss.”

Cascara sagrada, also known as California Buckthorn, is another laxative. It used to be an FDA-approved OTC drug for constipation, but concerns were raised about safety, and manufacturers didn’t want to spend the money to answer those concerns, so the FDA pulled their approval, and Cascara is now sold only as a supplement—and as such doesn’t have to meet “drug” standards. [11] 

Chitosan—a sugar obtained from the hard outer skeleton of shellfish, including crab, lobster, and shrimp—is used to treat obesity, high cholesterol, and Crohn’s disease. But there’s no real evidence it does anything for weight loss. And what little research there is says it doesn’t work if you’re not also cutting calories and exercising. [12] 

Overall, the science really doesn’t back up Sletrokor’s claims. 

Word On The Street About Sletrokor 

Apparently Sletrokor was once available on, but it’s easy to see why 18 Nutrition might have pulled it—the reviews are pretty abysmal. Sixteen reviewers gave it only 2.9 stars out of five, and nearly forty percent of those were one-star. Relegating their sales to their own website where they can moderate the reviews to skew positive probably keeps them in business. 

Energy seemed better but the stomach cramps and diarrhea don’t seem worth it

But back to Amazon. 

An anonymous “Amazon Customer” (2016, 5 stars) praised it: 

Absolutely hands down the most effective weight loss supplement I have ever used! No side effects, other than steady weight loss. Of course, following their directions as to how to take it fit perfectly into how I already eat, with larger meals earlier in the day, but still by far the best supplement I have ever used. [13] 

But “Autumn Pugh” (2015, 2 stars) wasn’t impressed: 

Energy seemed better but the stomach cramps and diarrhea don’t seem worth it. A medical website states that you shouldn’t take cascara sagrada for more than a week since it’s a laxative and can dehydrate you and cause loss of potassium. Wish it didn’t have this laxative in the formula. [14] 

And “BDJ” (2015, 3 stars) pointed out some further side effects: 

The Toilet is Your New BESTFRIENDI purchased 3 bottles(3 month supply) and I take 2 pills before breakfast and 2 pills before dinner with about 10 ounces of water. I’m 2 bottles down with 1 bottle to go. Side Effects: Con: Nausea, Diarrhea, Stomach Cramping. Pro: Eating less, feeling full sooner, feeling lighter [15] 

Overall, Sletrokor seems to be little more than a laxative and short-term appetite suppressor. It’s not the miracle pill it claims to be. There are plenty of other supplements out there for a fraction of the price. 

The Bottom Line: Is Sletrokor Worth a Try? 

Risky. Even though the customer service representative I spoke to did not try to persuade me that Sletrokor would help lose weight fast, they also admitted they don’t have enough data to know the exact average weight loss or give any prognosis on how much each individual will or could lose. Not inspiring at all. 

Combination supplements are always a gamble, but this one seems more so than usual. And the price is extortionate. Buy at your own risk.
