Prolessa Duo Review - Does This Appetite Suppressant Work? Are taste and ineffectiveness deal breakers?

By Summer Banks on Aug 24, 2016

Diet products either work or they don’t. Period. Let’s find out which one Prolessa Duo is. We concentrated on ingredients, side effects, scientific support and customer service. Additionally, we paid close attention to hundreds of consumer comments and reviews. We then refined and condensed to give you the info you need.

EDITOR'S TIP:

What is Prolessa Duo?

First off, Prolessa Duo is an appetite suppressant that has conjugated linoleic acid, palm oil and minerals. You can mix the supplement with a shake or consume as is once per day. The product supposedly assists with weight-loss. It’s easy to mix and you can drink it on the go, two benefits.

There’s no mention as to when Prolessa Duo hit the market, but the parent company, Herbalife, was founded in 1980.  You can purchase the product on the official website and through third-party retailers. We do like the longevity of the business and that we found a few positive customer comments, but read on…

I think it does ok as a fat burner...I just don't think it's for me.

Taste – “Not Flavorful?”

The first concern we had with Prolessa Duo was taste. “When you add a powdered appetite suppressant to a shake, you don’t want it to alter the flavor,” said our Research Editor. “If it just isn’t any good, dieters will more than likely stop using it.”

“This stuff taste like paint! I literally felt like I was drinking paint each time I used it,” said a consumer

“It has a medicine taste,” reported one customer.

We found that some customers had a different take on the taste of Prolessa Duo ingredients.

I have always enjoyed Herbalife products. I find their price to be a bit high, but the taste makes it worthwhile,” commented a dieter.

FDA Advisories – “Concerning?”

The Food and Drug Administration contacted Herbalife in December of 2014 because the company used a promotional video that implied the FDA supported products sold by the business. All relevant information has since been removed.

Ineffectiveness – “It Doesn’t Work”

According to numerous customer comments, when dieters  followed the recommendations for taking Prolessa Duo they didn’t see results. “I was on the program for 3 weeks & lost absolutely nothing,” commented a consumer.

“Didn’t notice any difference and fat percentage did not decrease,” said a customer.

“Did not lose anything and I am in the military so I’m constantly moving around. I actually gained a pound,” reports a user.

There were some users that reported changes while using Prolessa Duo. “I notice myself resisting the urge of snacking in-between meals and it feels awesome,” stated a dieter.

“I think it really works with a good nutrition plan,” said another.

Is There Any Real Science?

While the official Prolessa Duo website states the ingredients are “clinically tested,” we couldn’t locate published scientific research supporting the suggestion you’ll lose weight. At DietSpotlight, finding studies backing claims is critical. If there’s no science, why take a chance?

The Bottom Line – Does Prolessa Duo Work?

We’ve looked up and down this one – so, what do we think? After thoughtful consideration regarding Prolessa Duo, we’ve come to a conclusion. There are some positives like a few favorable comments and the longevity of the company, but we have reservations about it because of the lack of published clinical research supporting the weight-loss claims. Plus, we have concerns about the FDA judgments and the MLM opportunity, making purchasing smaller quantities more difficult.

If you’d like to rock your best body, we recommend going with a supplement containing ingredients backed by published clinical research that doesn’t have to taste good to work.

Among the best products we’ve seen in 2016 is one called Leptigen. The formula contains a four-ingredient proprietary blend, shown in published scientific research to stimulate fat loss and ignite metabolism. There’s no talk of negative side effects and reviews on the web report customers are seeing excellent results.

Additionally, the makers of Leptigen are confident in the supplement so they’re offering a Special Trial Offer, nice bonus.

What You Should Know

Prolessa Duo is a complimentary supplement that can be added to protein shakes or yogurt to improve weight loss success, according to the product description. The product is available as part of the Herbalife line, which means there is a natural push to purchase other Herbalife supplements to take in conjunction with Prolessa Duo. Herbalife, luckily, has a fair BBB rating. Prolessa Duo used to be available in pill form, but the company recently added the powdered product to the lineup. Based on the ingredient list for the supplement, there is no indication the dieter will lose weight with Prolessa Duo.

List of Ingredients

Ingredients:
  • Safflower Oil Derived CLA
  • Palm Oil
  • Oat Oil
  • Glucose Syrup
  • Sodium Caseinate
  • Silicon Dioxide
  • Ascorbyl Palmitate
  • Sodium Phosphate
  • Potassium Phosphate
  • Soy Lecithin
  • Natural Mixed Tocopherols
  • Natural Flavor

Product Features

CLA or conjugated linoleic acid has been around for more than a decade. One of the first popular CLA supplements with Tonalin, which claimed the dieter could take CLA without changing their current diet to lose weight. CLA is not clinically proven to boost or promote weight loss, but there are a few studies that suggest a small amount of fat loss occurs when taking CLA like the kind found in Prolessa Duo. There are also studies that claim CLA intake by obese individuals can have negative side effects like increased insulin resistance and increased risk of diabetes. On the official site more detail is given. Palm oil, the next ingredient in Prolessa Duo, is not considered a healthy fat. The oil is high in saturated fat and it may be oxidized, on some level, before being added to products and supplements. The unhealthy nature of palm oil is supported by the fact that it is a common ingredient in processed foods. Oat oil doesn’t appear to be a significant source of anything other than fat and saturated fat. Prolessa Duo also adds glucose syrup – a form of sugar, and various electrolytes to the formula. These have no impact on weight loss.

Advantages

    When I use Prolessa along with the Formula 1 Shake, not only do I see great results, but the flavor is also good too. When I take Prolessa alone, it doesn’t work and it doesn’t taste very well. I mix it in my mini blender. I usually add about 3-5 blueberries or raspberries along with a couple of packets of Splenda or Stevia.

    i am on a budget, and i see on the Prolessa it shows to add to Formula 1, i already purchased the Formula 1 (meal replacement) but i really can’t afford at this time to purchase the Prolessa, will i still have the same effects? or is there no point in doing the Formula 1 without the Prolessa

    some people think you can still eat whatever and that it should still work but it also matters on what you are eating. you cant eat junk then take a supplement and think it will magically make you loose weight and inches you have to watch calorie intake and what you eat along with exercise to make this work.

    Been taking Herbalife for little over a year now… I lost a total of 85 lbs… The Prolessa Duo is excellent… My first 30 trial I pulled of a total of 15 inches in a month… I’ve taken it 3 more times after and gotten the same results… I guess some people it works different with… Maybe a lot to do with your metabolism… I know I do the business side of herbalife and I know herbalife isn’t for everbody… Some people it works well with and some people it don’t…But I wouldn’t knock Prolessa Duo until you give it a try…

    I have been taking for two weeks and the only thing this product did so far is give me gas. I work out five days a week. Cardio, and light weight training and abdominal excercises. Not change in weight. Mad that I wasted my money unit. An Herbal life consult sold it to me and said it woot ks wonders! That’s a crock of bull! I don’t recommend it!

    How is your diet? Supplement or not, if you do not eat a clean diet (unless you are naturally skinny) you will not see abs or definition. I am a cpt . Is a common mistake people make thinking the gym alone will give them the result . No clean eating no abs. Supplements are to give you an edge, not the solution. I hate to see people not getting the right coaching it could have been just that .

    How that works I’ve tried it three times I’ve done it the way I’m supposed to I’ve done it in shots I don’t feel no different in fact I feel hungry and I taken in conjunction with the shakes and the supplements so to me it doesn’t do anything it’s too expensive to have no results if I have total control cell U loss and thermabond should be ok I took it for the last week and a half I barely lost a pound and a half

    [Reply]

    Amanda

    ummm, don’t get me wrong but isn’t that pretty good weight loss?? A pound and a half in a week and a half? That’s a pound a week! And that’s a healthy way to lose weight. Herbalife isn’t a get thin quick fix, it takes time and dedication. The products are designed to give you the best nutrients and natural ingredient. So your weight loss is good. Shouldn’t expect much more in the first week. I started prolessa and noticed it helped my lose the little pooch in front. As far as taste goes, I mix it in with a shake and can’t tell its there.
