Keto Lean Review: Does It Really Work?

Written By : Dr Ruby Shah   ✓ Fact Checked

BHBs pills are popular keto diet supplements, but will they boost your weight loss goals? Our Keto Lean review explores whether BHB supplements are worth it.

(Last Updated on November 29, 2022)

While the keto diet has some great benefits, it can be a little tricky to reach and sustain ketosis.

For this reason, ketogenic diet supplements are a favored facet of the diet, helping to achieve ketosis, burn fat, and suppress the appetite.

However, not all ketogenic diet supplements work, and some are downright scams.

To help you pick the right keto pills for your needs (and your money), we’re researching the biggest names on the market.

Here, we’re looking at Keto Lean by Envy Nutrition.

Our Keto Lean review explores the ingredients, effectiveness, side effects, customer experiences, business information, refund policy, and more.

Is Keto Lean your new keto companion?

We’ll see.

What Is Keto Lean?

Paoli, Antonio, et al. “Beyond weight loss: a review of the therapeutic uses of very-low-carbohydrate (ketogenic) diets.” European journal of clinical nutrition 67.8 (2013): 789. [/efn_note], or trying to lose weight via ketosis.

The bottle states “Advanced Weight Loss”, “All Natural”, “Gluten-Free”, and “Dairy-Free”.

It is made in the USA and is claimed to be third-party tested.

Unlike other similar keto or general weight-loss 1 supplements (that use herbal ingredients such as green tea or bitter orange), Keto Lean uses Beta-Hydroxybutyrate salts (BHBs).

These are the same ketones that the liver produces during ketosis.

The idea behind Keto Lean is to boost and elongate ketosis, provide clean energy, suppress appetite, and reduce keto flu symptoms.

About The Brand

Keto Lean is made by Envy Nutrition, which appears to be an Amazon affiliate brand based in Arizona, USA.

When searching their site, we couldn’t find any solid “about us” information.

While we discovered that the Envy Nutrition trademark has been “Dead” 2 or abandoned since early 2019, they posted a new video on their YouTube channel on June 1st, 2020.

It seems they are alive and kicking, but with very few views or engagement.

Keto Lean Ingredients

Keto Lean contains a proprietary blend, 800mg, containing:

  • Magnesium Beta-Hydroxybutyrate.
  • Calcium Beta-Hydroxybutyrate.
  • Sodium Beta-Hydroxybutyrate.

These three ingredients are known as BHBs, ketones the liver creates when starved of carbohydrates.

The liver pumps these out to provide energy to the brain, muscles, and organs.

These BHBs, as the names suggest, are connected to salts like sodium, magnesium, and calcium.

Note: in the marketing materials, we noticed that the description states that Keto Lean uses BHBs “along with caffeine anhydrous”.

This does not appear anywhere on the label, so we are unsure of whether caffeine is present in the capsules or not.

This is concerning, especially for those who suffer from insomnia.

We’re hoping this is simply a typo.

How Does Keto Lean Work?

  • BHB salts are released into the system and increase the ketone level of the blood.
  • BHB salts work to reduce appetite and cravings, helping to keep caloric intake down, leading to weight loss.
  • BHB salts cross the blood-brain barrier and provide energy to the brain. This is experienced as more energy, sharper focus, and a clearer head.
  • The ketogenic diet can lead to lethargy, headaches, and foggy-headedness. BHBs help to prevent these symptoms by providing fast energy.
  • BHB salts may also help to reduce inflammation, which can reduce the risk of chronic disease, and help the weight loss process.

Note: studies show that BHB ketones (or other exogenous ketones) may stop the body from burning fat 3.

This happens when you take too many extra ketones (i.e. far exceeding the dosage), so your body stops creating its own ketones to prevent ketoacidosis.

This is when the acid level (ketones are acids) of the blood becomes dangerously high.

Keto Lean Benefits

  • Easy to take.
  • Helps to transition into ketosis.
  • Provides clean and efficient energy.
  • Improves mental focus.
  • Suppresses appetite.
  • Reduces cravings.
  • May reduce inflammation.

Keto Lean Side Effects

We didn’t find any reviews stating negative side effects.

This isn’t surprising as Beta-Hydroxybutyrates are considered generally safe when the recommended dosages are adhered to.

However, like all supplements, there are risks of side-effects such as:

  • Upset stomach.
  • Diarrhea or constipation.

As previously noted, excessive dosage of BHB ketones may stop the body from creating its own ketones, therefore, slowing the fat-burning process.

Before taking Keto Lean or any other supplement, check with your doctor, especially if you:

  • Are pregnant.
  • Are breastfeeding.
  • Have existing medical conditions.
  • Are taking regular medications.
  • Have diabetes.

Keto Lean Reviews & Complaints

Customer reviews for Keto Lean are not abundant, but the ones that do exist are mostly positive.

The most common comment in the positive reviews is that Keto Lean suppresses appetite and reduces cravings.

There are no “I lost *** pounds in 2 weeks!” kind of comments as found in many keto supplement review sections.

However, we don’t see this as a bad thing, as such reviews are hard to believe.

“I think it’s helping to curb my appetite and decrease my cravings. I notice I have more energy as well. Time will tell how much it will help but currently I’m pleased with the results. Good Product!”

“Light smell, very easy to swallow, unlike a lot of similar supplements. Felt more energetic and noticeable appetite suppression when taking according to the guidelines, approximately 30 minutes before my biggest meal of the day.”

“It does help with appetite.”

The less positive reviews are based around the disappointment that Keto Fuel didn’t cause weight loss:

“I didn’t dislike the product but I didn’t lose weight.”

Is Keto Lean a Scam?

No, we are confident that Keto Lean (and Envy Nutrition) is not a scam.

Their website quality, security, and refund policies seem watertight and honest.

We didn’t come across any serious complaints or accusations of unwarranted credit card charges.

While we think your money and information is safe when buying Keto Lean, we’re unsure if it will provide the results you want.

How do I Take Keto Lean?

Take two capsules once a day, before a meal (about 30 minutes prior).

Keto Lean: Packages, Prices & Where To Buy It

You can buy Keto Lean from Amazon, however, it is unavailable at the time of writing.

Luckily, it’s in stock on the website, for $18.95.

Each bottle contains 60 capsules, enough for 30 days.

This is great value for money compared to similar keto supplements.

Money Back Guarantee

We were pleasantly surprised to see that Envy Nutrition offers a 100% money-back guarantee on all of their products.

You can send the product back, for any reason at all, and receive the entire payment back.

They also offer a price-beat if you find the product for a lower cost from another vendor.

See below how the official site looks like.

Keto Lean Pros & Cons


  • Secure site.
  • Great money-back guarantee.
  • Reasonably affordable.
  • Likely to suppress appetite and cravings.
  • Likely to boost energy levels.
  • Third-party tested.


  • Potentially contains hidden caffeine.
  • Effect on weight loss is unclear.

Keto Lean Review: Final Verdict

Keto Lean has some great things going for it, such as a decent money-back guarantee, third-party testing, and a safe ingredients list.

Customers have experienced more energy and a reduced appetite, both of which are excellent factors when following the ketogenic diet.

However, if you’re looking for a quick fix to shed pounds, this isn’t the ticket.

BHB ketones might help with energy levels and keep caloric intake down, but they won’t magically melt away fat, like some people assume they will.

If you’re considering giving Keto Lean a try, run it past your doc first, and be sure to follow the instructions.
