What is Keto Slim RX?

Keto Slim RX premium diet pill is a ketone supplement that delivers exogenous ketones to the body and, eventually, the bloodstream. We found two listings for the supplement on Amazon – both with the same name and, from the looks of it, the same ingredients. The product is supposed to be a natural formula and organic supplement that qualifies as a weight-loss pill for women and men – but do you really get an advanced ketosis weight-loss pill?

Does It Work?


Who Makes Keto Slim RX?

The more popular of the two Keto Slim RX listings share Nutra4Health as the distributor. The company is responsible for numerous products for weight loss, brain health, and overall wellness.

What we first thought was the official website for Keto Slim RX is actually an affiliate site. When you click the link to purchase the ketone supplement, you are taken to a Trim Pill Keto sales page.

Keto Slim RX Claims

Without an official website (the company website doesn’t feature any product information), we must lean on the Amazon description to finding product claims. Based on that description, Keto Slim RX claims:

  • Made in the USA in an FDA-approved facility
  • More than a typical fat burner
  • Made of the highest-quality ingredients
  • Improve physical and mental wellbeing
  • Suppress hunger for high-carb foods
  • Improved focus
  • Appetite control
  • Burn fat naturally
  • Get into the metabolic state of ketosis and stay there.

Keto Slim RX Ingredients

There are three ingredients in Keto Slim RX natural formula. Each is a form of beta-hydroxybutyrate (BHB). This exogenous ketone is supposed to help the user get into nutritional ketosis faster and stay in ketosis longer. The ingredients are:

Ingredient Details

Details on Ingredients

What does beta-hydroxybutyrate really do in the body, and are the three varieties all that different? Let’s take a look at the research.

Calcium BHB, Magnesium BHB, Sodium BHB

The Journal of Nutrition and Metabolism shard research in 2018 that serum beta-hydroxybutyrate levels in blood increased when a supplement containing sodium and calcium beta-hydroxybutyrate was consumed.

Further research in Nutricion Hospitalaria claims adverse effects related to exogenous ketone supplementation are rare.

Recent research published in Scientific Reports shows beta-hydroxybutyrate promotes an anti-inflammatory response and, as such, may help to improve mood and reduce the effects of stress.

Weight Loss

Keto Slim RX, Ketosis and Weight Loss

So, we know that ketone supplements that contain beta-hydroxybutyrate may increase ketone levels in the blood – which could help with nutritional ketosis. But, is ketosis proven to help with weight loss?

Research into the power of ketogenic diets has been completed since the late 1960s (or earlier). In recent years, especially with the popularity of ketogenic diets, research has skyrocketed.

A 2013 study in the European Journal of Clinical Nutrition shows men and women following a ketogenic diet are more apt to lose weight when BHB levels increase.

By 2014, research in the International Journal of Environmental Research and Public Health shared that nutritional ketosis is an effective means of weight loss – and may even improve heart health.

Research published in 2015 in the journal Obesity Reviews supports the idea that ketosis causes appetite suppression – one means of promoting weight loss.

The year 2016 brought some negative press claiming that ketogenic diets negatively impact skeletal muscle mass, as published in the International Journal of Sports Nutrition and Exercise Metabolism.

By 2018 ketogenic diets were back on the stage with the fantastic claim, as published in Current Nutritional Reports, that ketogenesis “promote[s] breakdown of excess fat stores… [and] sparing of lean muscle.”

Side Effects

Keto Slim RX Side Effects

We found no mention of side effects associated with beta-hydroxybutyrate, but we know there are side effects of ketosis. The following side effects may last the duration of your low-carb diet, though most will ease off as your body adjusts to burning fat for fuel.

While in ketosis, you may experience:

  • Nausea
  • Headache
  • Fatigue
  • Hunger
  • Carbohydrate cravings
  • Sweet-smelling urine
  • Bad breath

How to Use Keto Slim RX

Each bottle of Keto Slim RX contains 60 capsules or 30 servings. The directions advise the user to take two pills each day about 30 minutes before meals. The term “meals” sounds like you take six capsules each day, two at each meal, which would mean one bottle would last only 10 days.

Cost and Where to Buy

What Users Are Saying

What Users Are Saying

“Keto Slim helps curb your appetite, no weird side effects. I found I’m eating less and I’m not hungry. Started Keto diet with Keto Slim pills Oct 1 and have lost 25 pounds.”

“Don’t waste you money does not work!!! – This product does not work been taking 3 weeks today lost nothing!!!”

“Nothing is working – I have been on this product for three weeks and nothing has changed. Weight is the same and no change in inches. It may be too soon, but all that I have read is that this product has shown at least 20 to 28 lbs lost in one month. Am disappointed that I haven’t seen any changes. I have been on low carb, low everything diet because of diabetes and food allergies for a long time and thought that I had a jump on the whole process. A little change would have been hopeful that I was going in the right direction.”
