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.
What is Prolessa Duo?
First off, Prolessa Duo is an appetite suppressant that has:
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…

Prolessa Duo 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? 
What Users Are Saying
“This stuff is so awesome. I have lost 15 lbs. using this and I love it. I will be ordering more soon.”
“Wish taste was different but it works.”

“It’s ok. Does not mix well with any fluids.”
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 this year is one called Burn HD. 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.
