There’s been a lot of buzz about Herbalife Prolessa Duo, so you’ve probably come across this weight management drink while seeking the best diet pill to help you get rid of excess stored fat as efficiently as possible.

It’s difficult to fully understand what exactly to look for and whose promises to trust on the market that’s oversaturated with numerous distrusting fat burners.

To find out how effective this diet shake is and whether it lives up to its claims and your expectations, our expert team read out hundreds of customer reviews and researched clinical studies on the quality and effectiveness of its ingredients, side effects, cost, and other details you need to know before deciding whether to try it out.

This thorough Prolessa Duo review reveals what we’ve discovered.

What Is Herbalife Prolessa Duo?

Prolessa Duo is a powdered weight loss supplement manufactured by Herbalife International of America, Inc., a US-based company that sells health and wellness products.

Prolessa Duo claims to control hunger and enhance body fat reduction.

This dual-action formula is meant to be mixed with other Herbalife products or any other weight loss shake and used as a high-calorie meal replacement that helps you reduce calorie intake, curb cravings, and create a feeling of fullness, enabling you to burn fat and lose weight gradually.

The Manufacturer

Herbalife Nutrition is a widely-known brand founded in 1980 that creates and globally distributes herbal nutritional shakes and various other health, dietary, and weight loss supplements, including Prolessa Duo fat burner.

The company also claims to offer successful weight loss programs professionally developed and guided by their trained experts (dieticians and nutritionists).

Although the company has been on the market for a few decades and has a 2-star BBB rating, customers have filed over twenty complaints against it, mostly about overcharging, fraudulent charging, membership canceling, and refund issues.

How Does Prolessa Duo Work to Help You Lose Weight?

The main Herbalife promise is that the Prolessa Duo diet powder mix is a unique blend of Conjugated Linoleic Acid (CLA), palm and oat oils that help you burn fat and reduce the intake of unhealthy food calories, and increase satiety for extended periods, enhancing weight loss.

Herbalife Prolessa Duo fat burner pros:

  • It promises to help fight overeating by keeping you full for longer.
  • It contains CLA claimed to reduce fat, helping you lose weight faster.
  • It’s free of stimulants and contains only natural substances.
  • This weight loss powder is easy to mix with water and can be used as a meal replacement.
  • Herbalife offers a 30-day money-back guarantee for customers who aren’t completely satisfied with the product.

Although Herbalife claims that the Prolessa Duo is made with clinically tested ingredients that help curb hunger and reduce body fat, the company doesn’t provide any further insights into those clinical trials.

The oat and palm oil might give you a feeling of fullness and help curb food cravings that contribute to weight gain.

Still, CLA seems to be the only research-backed compound with potential fat loss effects. However, scientific evidence on the CLA fat-burning potential in humans is somewhat mixed. Various studies show modest results and minimal long-term weight loss effects of CLA supplementation, even in combination with an exercise program [1] [2] [3] [4] [5].

Let’s see what precisely this weight loss drink contains

Herbalife Prolessa Duo Ingredients

Mainly natural ingredients you can find in the Prolessa Duo proprietary blend include Safflower Oil- Derived Conjugated Linoleic Acid, Palm Oil, Oat Oil, Glucose Syrup, Sodium Caseinate, Silicon Dioxide, Ascorbyl Palmitate, Sodium and Potassium Phosphates, Soy Lecithin, Natural Mixed Tocopherols, and Natural Flavors.

Interestingly, Prolessa Duo doesn’t contain any protein or fiber content that typically keeps you feeling full longer, but at least it contains safflower oil-derived CLA that’s claimed to reduce appetite and curb hunger.

Still, I’m not sure how effectively CLA can enhance fat loss, help control hunger, and prevent snacking between meals when used on its own [6].

Herbalife Prolessa Duo Downsides and Side Effects

Besides not containing any fiber or protein in addition to CLA to keep you satiated, Prolessa Duo lacks ingredients known for burning fat, vital minerals, vitamins, amino acids, and many other valuable nutrients I’d expect to see on the list of active ingredients of a fat burner marketed as a meal replacement product.

It makes the overall quality and nutritional value of this powder questionable.

What’s more, it contains soy, that’s often GMO (unless stated differently) and linked to causing hormonal imbalances (affecting estrogen levels), triggering thyroid issues, and many other side effects.

Some negative customer reviews point out the poor flavor of this diet product (comparing it to drinking paint), return and refund issues, lack of weight loss results, and greater risk of adverse reactions.

Now you may be wondering:

Is Prolessa Duo Safe?

It is probably safe, but if you’re allergic to soy or dairy, it may be better to consider another weight loss diet pill.

Although there are no severe side effects consumers have officially reported in Prolessa Duo reviews (apart from digestive discomfort and blurred vision along with migraines), we’ve researched the key ingredients in its formula and come up with the possible side effects users might experience.

These may include headaches, fatigue, nausea, indigestion, diarrhea, constipation, upset stomach, and allergic reactions.

To avoid any potential health problem this supplement might cause, I’d advise you to consult a healthcare professional before you start consuming the Prolessa Duo weight loss program.


  • This powdered weight loss product isn’t best mixed with hot or acidic drinks.
  • It doesn’t contain ingredients proven to boost your energy levels and directly burn fat.

It’s pretty expensive when compared to other diet pills and similar products.

Where Can You Buy Herbalife Prolessa Duo?

Although it’s available for purchase from various online vendors and Herbalife independent distributors, it’s best to buy a 7-day program or a 30-day program of Prolessa Duo directly on the Herbalife official website to be eligible for a full refund and product return or exchange.

A number of negative reviews from consumers have reported resellers selling out-of-date supplements and not offering a satisfaction-guarantee Herbalife gives to all unsatisfied customers.

The product price varies, depending on the reseller.

Still, it’s generally overpriced no matter where you get it, as it’s recommended to be mixed with other weight loss pills and nutritional shakes you need to buy.

How to Use Prolessa Duo Herbalife

The manufacturer recommends adding one scoop of Prolessa Duo powder per day to your favorite Herbalife shake or other protein-based products, such as milk or yogurt, and mixing it for five to ten seconds.

Other Users’ Weight Loss Experience With Herbalife Prolessa Duo

When researching online reviews for products sold by a multi-level marketing company like this one, it’s critical to distinguish numerous exaggerated fake reviews left by those trying to earn a commission off sales from genuine customers’ opinions left after certified purchases.

Luckily, we’ve done all the hard work for you and found out that thousands of Herbalife Prolessa Duo reviews are a mix of positive and negative user experiences.

Many consumers complained about the powder’s horrible taste (like paint, plastic, or chemicals), small container size, and hefty price tag. Even many satisfied customers who stated that they lost a few pounds with this supplement (and a healthy diet) wished the product was cheaper.

Many customers had problems receiving the expired or nearly expired supplement, getting the product returned and their money refunded, even reaching the seller. In contrast, others had positive customer service and delivery experiences.

Also, many people reported they were still hungry and noticed absolutely no weight change despite being on a strict diet and exercise regimen while using this weight loss powder.


My Personal Experience With Herbalife Prolessa Duo

How does Prolessa Duo compare to other fat burner supplements?

Well, I agree with the users claiming that you’re basically buying a CLA supplement in a powdered form and paying quite a high price for the brand name.

There are much more effective, nutritionally richer powder supplements and weight loss products available on the market, containing higher-quality scientifically proven ingredients that burn fat.

Other weight loss products we've reviewed:

Is Herbalife Prolessa Duo Worth It?

Based on what you’ve learned from our in-depth Prolessa Duo review, I hope you’ll be able to determine whether it’s worth a try.

Despite the brand longevity and the supplement containing a natural ingredient that might help suppress appetite, I’m not impressed by its effects and mediocre reviews. Still, your decision will depend on your taste, budget, and many other factors.

I’d rather opt for a reasonably priced fat burner with effective ingredients clinically proven to boost metabolism and energy, burn stored body fat, curb cravings, and help trim down your waistline without potential side effects.

Our expert team recommends checking out PhenQ, a fat burner backed up by hundreds of thousands of positive user experiences and a longer money-back guarantee for a risk-free purchase.
