Because of my job as a fitness trainer, I am always focused on discovering the best weight loss supplements that can help athletes stay in shape.

Many fat burners are on the market, but I would like to single out the Nutrilite CLA, a natural fat-burning supplement. Due to the good reviews, I decided to try it to see how effective it is.

In this Nutrilite Lean Muscle review, you will find out if this supplement can help you lose body fat by maintaining lean muscle mass.

Let's get started.

Amway Global - Nutrilite Product Line of Supplements

Nutrilite is a health product brand that sells plant-based supplements and multivitamins.

Through "American Way" or Amway Global, Nutrilite is distributed over 100 countries and claims to be the world's leading brand of nutrition products to support human health.

Carl F. Rehnborg formulated Nutrilite ingredients as a vitamin and mineral supplement in 1934 after realizing the importance of phytonutrients and their benefits to general health [1].

He was among the first to develop the MLM or multi-level marketing sales approach based on a concept from one of his customers.

And in 1959, Jay Van Andel and Rich DeVos founded Amway after being Nutrilite distributors for nearly a decade, and they later acquired Nutrilite in 1972.

Today, the company remains a thriving MLM business promoting a wellness lifestyle to North and South America, Europe, and most of Asia.

What is Nutrilite Lean Muscle CLA?

Nutrilite Lean Muscle CLA is a dietary supplement designed to help you lose fat while maintaining muscle mass. Its manufacturer uses agricultural systems that don't use pesticides, herbicides, or synthetic chemicals, so you can be confident that it is made entirely of organic, natural, and high-quality ingredients.

The Nutrilite Lean Muscle dietary supplement is essentially a CLA supplement that can help with bodybuilding and weight loss.

Suitable for Men & Women

All Nutrilite vitamin supplements contain clinically proven ingredients derived from vegetable sources.

The Nutrilite Lean Muscle dietary supplement contains one active ingredient and two inactive components. Let's begin with the inactive components.


The gelatin component contains a high concentration of amino acids, which have numerous health benefits, such as reducing joint and bone pain, improving brain function, and reducing the signs of aging [2].


In addition, the vegetable glycerin in this supplement is considered safe. It has various benefits, including improving skin health, increasing hydration, and relieving constipation. It also has antibacterial properties to protect the skin against disease-causing microorganisms [3].

The main active component in Nutrilite Lean Muscle is Conjugated Linoleic Acid.

Conjugated Linoleic Acid

CLA is the active ingredient in this supplement. Conjugated Linoleic Acid (CLA) is a type of polyunsaturated fatty acid that has been shown to increase weight loss by burning excess body fat.

CLA can be obtained from a variety of sources, including beef and dairy products. The Nutrilite Lean Muscle dietary supplement contains CLA derived from pure safflower oil.

Benefits of Using Nutrilite Lean Muscle CLA

A Nutrilite Lean Muscle dietary supplement can offer several advantages. However, to get the most out of weight management, it's best to combine it with a low-calorie diet and weight loss programs.

By using Nutrilite Lean Muscle CLA, you can:

Reduce Body Fat

Nutrilite Lean Muscle may come in very handy for athletes who want to tighten their belly fats quickly and safely.

Animal studies have shown that CLA reduces body fat in animals by increasing the amounts of specific enzymes and proteins that increase energy expenditure resulting in fat breakdown [4].

However, more studies are needed to support effective fat loss in humans.

Retain Lean Muscles

Nutrilite Lean Muscle may also help you in building lean muscles.

A study on the effects of CLA on obesity shows that it may contribute to muscle fiber changes, alteration of the intracellular signaling pathways in metabolism [5].

Thus, CLA may not only cause a reduction of body fat, but it can also increase lean body mass.

  • It helps you lose your unwanted fat and retain lean muscle
  • It boosts your energy for workouts
  • All-natural, high-quality ingredients
  • You can buy it online or through a distributor anywhere in the world
  • May cause certain side effects over prolonged use
  • No scientific evidence to support the efficacy

Can I Purchase Nutrilite Lean Muscle Directly From Their Website?

You can purchase Nutrilite Lean Muscle CLA directly from their official website.

The process is simple and convenient. Once an order is placed online, you can track your order status with the provided tracking numbers sent in your email.

They also offer a guarantee in wrong order returns. You can expect the return process to take 11 to 17 working days.

I didn't have any trouble ordering and receiving the product. However, I find that the cost of Nutrilite Lean Muscle CLA is relatively more expensive than other products.

How to Take This Fat Burner?

You should take two soft gels of Nutrilite Lean Muscle CLA three times per day, preferably after meals.

Research suggests that daily doses of at least 3 grams CLA are adequate to support burning calories and amounts of up to 6 grams per day showed no reports of severe adverse side effects in humans.

Also, one study published that drug administration of 3.4 grams of CLA per day for six months significantly reduced fats in the legs of healthy, overweight, and obese men [6].

Thus, athletes who regularly exercise and use this food vitamin in recommended amounts may improve total strength during heavy resistance training.

However, overweight individuals with high blood sugar levels should use extra caution in taking Nutrilite Lean Muscle CLA as it may heighten the risk for diabetics [7].

I highly recommend that you consult a physician to provide medical advice if you are under 18, pregnant or nursing, and taking prescriptions due to a medical condition.

What Are The Potential Side Effects Of Nutrilite Lean Muscle?

Nutrilite Lean Muscle may cause relatively mild side effects such as stomach upset, fatigue, diarrhea, rashes, and nausea.

People with diabetes and bleeding disorders should not take Nutrilite Lean Muscle CLA, as this may have a few severe effects that may worsen diabetes and slow blood clotting.

I used it for a few months primarily to support my diet. I didn't feel any stomach upsets and nausea during that time.

"The impact of CLA on heart disease and diabetes needs to be investigated further."

- Cindy Moore, MS, RD, Director of Nutrition Therapy at The Cleveland Clinic

As with taking a supplement pill or any vitamins, it is best to consult a physician for an initial assessment.

Is It Better Than Other Weight Loss Products?

We tested Nutrilite Lean Muscle against three leading weight loss supplements to see if it could hold its own. Here’s what we found.


Our review confirms that PhenQ has gained a reputation for being a trustworthy supplement with a holistic weight loss approach.

I’ve had many discussions with fitness clients over the years about losing weight and how achieving and maintaining long-term results takes more than one approach.

The makers of PhenQ understand this; it targets stored fat, boosting energy, suppressing appetite, enhancing focus, and blocking new fat production.

Our test group reported significant increases in energy and reduced hunger cravings when using PhenQ alongside our diet and exercise plan. Most also achieved noticeable weight loss that we tracked by taking body measurements at regular intervals during the testing phase.

I took both supplements to our dietitians and sat with them to discuss the ingredient labels. They confirmed that PhenQ contains optimal thermogenic and appetite-suppressing ingredients such as capsimax powder, nopal, L-carnitine, and caffeine and proven a-Lacys-Reset® formula.

I ordered PhenQ directly from the official site and took advantage of incentives. There are a lot of fake supplements out there, so ordering from the official website is always advisable.


The expert shared in our Leanbean review that it aims to meet women's specific weight loss needs, and unlike Nutrilite Lean Muscle, it uses a vegan-friendly formula.

Leanbean contains thermogenic ingredients like green coffee beans and turmeric, appetite suppressants like Glucomannan and chromium, and B vitamins to reduce fatigue. Nutrilite does not include any of these ingredients in its formula.

In our test group, participants reported significantly reduced snacking while taking Leanbean over several weeks but stated they wanted more caffeine.

While some find the six-pill daily dose, three times that of Nutrilite Lean Muscle, too much, many users report feeling the benefits around the clock.

One crucial feature of Leanbean is its clear ingredient label, with no proprietary blend. As a fitness trainer, this is critical for me, especially if I recommend supplements to my clients.

I ordered directly from the Leanbean website and received free shipping and a bulk order discount, and I was delighted with what I had saved.

Instant Knockout

You can find Instant Knockout in about every gym these days, but it didn’t start that way. Initially created for elite athletes and bodybuilders, Instant Knockout maxes out ingredient amounts in its powerful formula.

First, it contains caffeine, and a lot of it with 300 mg. For some in our test group who experienced adverse effects like jitters or digestive upset, the caffeine content proved to be too much. Others loved the energy kick that fueled their workouts and entire day.

Instant Knockout includes essential ingredients such as cayenne for thermogenesis, Glucomannan for suppressing appetite, L-theanine for improved focus, and vital vitamins to reduce fatigue.

Unlike Nutrilite Lean Muscle, Instant Knockout utilizes a veggie capsule, making it suitable for vegetarians and vegans.

I went to the official website to purchase for testing and found the price comparable to other fat burners. Included in my order were complementary training and e-guides that I found to be a valuable asset for anyone looking to get the most out of Instant Knockout.

Customer Reviews

Here's what actual customers have to say about the product.

For Ismael, one month of use was enough to prove that the product works when combined with regular workouts and low-fat diets. He loves how this product helped him build lean, strong muscles while shedding excess body fat. He considers this product to be an excellent health investment. -Ismael - California, USA

Glyzel strongly recommends this product because it has helped her lose belly fat. She is excited to share that it worked well for her, and now she feels better about her body image. She asserted that she had no regrets about using it. -Glyzel - Kingstown, St. Vincent, and the Grenadines

Tyler likes the lean muscle product because it has helped his endurance during his strength training regimen. It helped him lose fat and gain lean muscles. He is pleased that his waist has shrunk by 4 inches after only a year of using the product. -Tyler - Buford, GA

Nutrilite Lean Muscle CLA: Our Verdict

Nutrilite Lean Muscle CLA may retain total lean mass by affecting body composition and regaining fat.

My experience and research suggest that this vitamin and mineral supplement may reduce fat mass in certain body areas, increase fat-free mass gains, and improve the resting metabolic rate.

But I must admit that my Nutrilite experience was not exceptional because I expected more powerful results. If you are tolerant of caffeine and want to lose weight faster, PhenQ might be a better choice.

PhenQ is considered the best weight loss pill on the market today.

You can take the pill alone or in combination with an eating plan and weight loss program. It has been proven to burn stored fats, suppress appetite, block fat absorption, and boost stamina by many users.

To sum it all up, it is still best to improve your lifestyle by eating fewer carbs, controlling your appetite, and having regular quality working out, as these dietary supplements are just made to bridge any nutritional gaps in your diet.
