If you’ve been shopping around for a weight loss drink, you’ve probably stumbled across Herbalife’s product range at some point. One of their most acclaimed products is CLA-drink named Prolessa Duo. In this Prolessa Duo review, we’re taking an in-depth look into this product to establish whether or not we believe it is capable of helping users lose weight.
Readers please note that statements on this page are fair comment based on observation. This content is produced on a matter of public interest. Statements on this page are our honest opinion.
What Is Prolessa Duo?
Prolessa Duo is a weight loss drink created by a US-based health and wellness MLM company named Herbalife.
One bottle of Prolessa Duo costs $28.95 and will last users for 7 days, however it is also available in a 30-day supply for $110.30.
This product is most easily available via the official Herbalife Prolessa Duo website, however it can also be purchased on Amazon or directly from a Herbalife independent reseller (be sure to check the sell-by date, as there have been numerous reports of resellers selling out-of-date supplements).
Much like many other products in Herbalife’s range, Prolessa Duo is designed for those who are looking for help losing body fat.
The product itself is a complex of Conjugated Linoleic Acid (CLA) and various oil extracts. Herbalife describe Prolessa Duo as a “dual action weight loss formula” that uses “clinically proven ingredients”.
Consumers of Prolessa Duo are promised effects such as increased fat loss and reduced appetite levels.
Does Prolessa Duo Work?
After conducting some research into this product, we believe that Prolessa Duo could potentially prove to be helpful for supporting weight loss, as long as it is used in the context of a calorie-restricted diet.
Despite what you may have believed, Prolessa Duo isn’t truly capable of burning fat; no ingredients inside this product have the ability to directly and independently “burn body fat”. Furthermore, it’s not going to boost your energy levels or metabolism speed, and it doesn’t contain anything that’ll promote satiety (i.e. a feeling of fullness) in users.
It is our opinion that Prolessa Duo should be looked upon as a weight loss support formula, rather than a miracle weight loss drink.
As previously mentioned, Prolessa Duo is essentially a CLA-drink with added oil extracts. While CLA does have some scientific backing showing it can help shrink fat cells when 3g is consumed per day in conjunction with a low-calorie diet for a period of 12 weeks, we were unable to find any rock-solid scientific evidence to support the statements that the oil extracts help provide appetite-suppressing effects.
Despite the product containing CLA, the formula itself is a little on the basic side, and doesn’t really measure up to the market-leading weight loss drinks in our opinion.
In order to see genuine fat loss results from Prolessa Duo, you will need to use the product for at least 12 weeks while sticking to a low calorie diet (ideally consuming 500-1000 calories under your daily caloric maintenance number). If you’ve got the willpower to do this, we don’t see why you wouldn’t see reasonably decent results from this product.

Are There Any Prolessa Duo Reviews From Customers?
We have found the following Herbalife Prolessa Duo review testimonials via customers online:
I’ve lost 10 pounds total with this powder combined with my formula 1 shakes. Love this stuff.
This product didn’t work for me. I generally workout 4 times a week and eat a healthy diet. I didn’t lose any weight and didn’t feel like it curbed my appetite by any means. It also gave me stomach issues that I don’t have now that I’m off the product.
Our Final Verdict On Prolessa Duo
To conclude our Prolessa Duo review, it’s a bit of a mixed bag – there are things that we like about it and things that we aren’t too blown away by.
Starting with the positives, we like how this product contains CLA – there are many scientific studies showing that this substance can help shrink fat cells. We also like how this product is drinkable, rather than in softgel form, making it very easy to consume the required 3g per day.
Obviously, there are some downsides to Prolessa Duo too. This product isn’t pushing any boundaries; for a weight loss drink, the formula is very basic and underwhelming – we don’t believe that this product will be any more effective than simply taking a generic CLA 1000mg softgel supplement that can be bought for pennies on the dollar. Finally, the product doesn’t contain any ingredients that’ll boost your energy levels or metabolic rates.
