(Last Updated on November 9, 2022)

Are you working on getting your weight, energy levels, and mental focus up to scratch?

Good on you.

Perhaps you’ve chosen the ketogenic diet as your path forward.


However, the ketogenic diet does come with some downsides, especially at the start.

You can experience energy slumps, headaches, cravings, and foggy-headedness.

To ease the road and stay on track for a successful keto journey, you may need a high-quality supplement.

We’re turning our attention to Keto Slim RX, a dietary supplement with a minimal ingredients list and interesting customer responses.

Our Keto Slim RX review fills you in on ingredients, side effects, benefits, customer experiences, and a final verdict.

What Is Keto Slim RX?

Keto Slim RX is a ketogenic supplement made by Nutra4Health LLC.

It claims to burn fat, increase energy, boost metabolism, and curb appetite and cravings.

It is made with ketones called beta-hydroxybutyrate and has varied customer responses.

While there’s minimal information about Keto Slim RX and Nutra4Health LLC, we know that:

  • It’s made in the USA (according to the Amazon listing).
  • Made in a GMP-certified facility.

About The Brand

Nutra4Health LLC is a very slippery business to find information about.

Their website 1 is very vague and incomplete, with no “about us” information or product listings.

In short, the almost non-existent information regarding the company is a red flag.

We cannot assess their practices, other products, or find more reviews.

Keto Slim RX Ingredients

Keto Slim RX has a minimal ingredients list, containing only Beta-Hydroxybutyrate salts.

These are the same ketones as the ones the body produces when in ketosis.

  • Calcium Beta-Hydroxybutyrate 62mg.
  • Magnesium-Hydroxybutyrate 32mg.
  • Sodium-Hydroxybutyrate 10mg.

GoBHB Proprietary blend 800mg:

  • Calcium Beta-Hydroxybutyrate 62mg.
  • Magnesium-Hydroxybutyrate 32mg.
  • Sodium-Hydroxybutyrate 10mg.

GoBHB is a ketogenic workout supplement made by Compound Solutions 2.

It is targeted toward athletes and gym bunnies as well as “gamers and busy professionals” due to the focus-boosting abilities of BHBs.

How Does Keto Slim RX Work?

In simple terms, exogenous BHB ketones are helpful because they cross the “blood-brain barrier”.

This barrier strictly keeps certain substances out 3 (even helpful medications), while letting others in.

BHBs are permitted, meaning they can travel directly to the brain, ready to be used as energy.

BHBs are thought to provide fast, clear, and effective mental energy as well as physical oomph.

  • Beta-Hydroxybutyrates could lower ghrelin levels 4 (the hunger hormone), reducing appetite and cravings. This helps to keep caloric intake at weight-loss level.
  • BHBs may help to regulate blood sugar levels, helping to reduce energy slumps and cravings for carb and sugar-rich foods.
  • BHBs may reduce keto flu symptoms such as headaches and energy slumps, helping the user to stick to the keto diet.
  • BHBs may help to boost physical and mental energy levels during exercise, helping to burn more calories.

Note: these are the hypothetical benefits as stated by the product and by similar products that use BHBs.

However, there is lacking evidence for the weight loss abilities of exogenous ketones and BHBs.

Plus, user reviews are lacking in reports of weight loss when using Keto Slim RX and similar supplements.

Keto Slim RX Benefits

  • Easy to take.
  • Passes the brain-blood barrier to be used as fast-acting energy.
  • Boosts cognitive function and focus.
  • Reduces appetite.
  • Curbs carb and sugar cravings.
  • Reduces keto flu symptoms.

Keto Slim RX Side Effects

Keto Slim RX contains only BHBs, which bodes well for the safety and low likelihood of negative side effects.

Because BHBs are a familiar substance to the body (it creates them when starved of carbohydrates), the body responds well to them.

While BHBs are considered safe, they may cause:

  • Sore stomach.
  • Diarrhea or constipation.
  • Nausea.

We didn’t come across any customer reviews mentioning side effects.

However, when taking any new supplement, it’s really important to make sure it’s compatible with your health history and current conditions.

Check with your doctor before taking any new diet supplements, especially if you:

  • Are pregnant or breastfeeding.
  • Are trying to conceive.
  • Are under 18.
  • Have had previous experiences with eating disorders.
  • Are taking regular medications.
  • Have existing health conditions.

Keto Slim RX Reviews & Complaints

Customer reviews for Keto Slim RX are unfortunately low, with many 1-star reviews (more so than 5-star).

Most of the negative reviews are rooted in the fact that the user did not experience any change when taking Keto Slim RX.

For example:

“Took 2 bottles of these hoping it would simply give me a kick-start as I have plateaued in my weight loss. Nothing happened. Zip. Nada. No negative side effects other than it not working.”

The positive reviews, on the other hand, are very vague and we have to wonder if they’ve been posted as an incentive.

For example:

“I really like KETO SLIM RX. It really helped me lose weight easily! I’m sticking with K.S.RX.”

Is Keto Slim RX a Scam?

It’s hard to tell if Keto Slim RX is a scam due to the very little company information and customer reviews online.

However, we found that the company, Nutra4Health LLC scored a C on Fakespot 5.

Plus, the high percentage of 1-star reviews claiming that Keto Slim RX did nothing for the user tells us that perhaps it’s more bark than bite.

How do I Take Keto Slim RX?

The packaging directs the user to take two capsules three times a day, before eating.

Keto Slim RX: Packages, Prices & Where To Buy It

Keto Slim RX is listed on Amazon, but it is not available at the time of writing.

We couldn’t find a Keto Slim RX stockist anywhere else online, so you may be out of luck if you’re wishing to give it a try.

Money Back Guarantee

We could not find any substantial information about a returns policy or money-back guarantee, unfortunately.

This means you must be prepared to lose your cash and be stuck with a bottle of pills if you are unhappy with Keto Slim RX.

See below how the official site looks like.

Keto Slim RX Pros & Cons


  • Low risk of side effects.


  • Mostly negative reviews.
  • Unlikely to lead to weight loss.
  • No money-back guarantee or refund.

Keto Slim RX Review: Final Verdict

Keto Slim RX is a simple ketogenic supplement containing BHB ketones and the GoBHB proprietary blend.

While it is unlikely to cause side effects, it’s also unlikely to boost your weight loss efforts.

If you’re wanting to shed fat and gain more energy, the ketogenic diet itself will be far more effective than Keto Slim RX pills.

A calorie deficit, (with reduced carbohydrates and sugars), better sleep, and regular exercise are safe and science-based ways to trim down and feel energized.

While ketogenic supplements can be very helpful, it pays to find ones that come from reputable, transparent companies with money-back guarantee policies.

Nutra4Health doesn’t tick these boxes.
