You’re about to learn everything you need to know about USN Diet Fuel Ultra Lean. We created a detailed review, closely scrutinizing the ingredients, side effects, clinical studies and level of customer care. Moreover, we focused on plenty of user comments and dieter reviews from around the web. Lastly we compacted all the facts and responses we found to give you the bottom line.
What You Need To Know
USN Diet Fuel Ultra Lean is a “nutrition shake” for women and men that is claimed to promote weight loss and help with lean muscle maintenance. It is available in five different flavors, which include chocolate, vanilla, strawberry, banana caramel and café latte. Since this is a company based in the UK, it does not look like this supplement is available to people in other parts of the world, such as the US. The primary ingredients found in this supplement powder include; Whey Protein Concentrate, Soy Protein Isolate, Milk Protein Isolate, Garcinia Cambogia, Micronized Milk Mineral Complex, Inulin and various vitamins and minerals. Each scoop/serving provides 25.4 grams of protein. USN Diet Fuel Ultra Lean is simply added to a glass of cold water and then consumed.
It looks like USN Diet Fuel Ultra Lean was released in 2013. This product contains a decent amount of fiber per serving and there are some positive comments posted online. Also, this product can be used at any time, but read on…
Bad Taste – A Concern?
“You will notice quite a few customer complaints online regarding the actual taste of USN Diet Fuel Ultra Lean shakes. This is never a good thing because how will you stick to these protein shakes if you can’t stand the taste?,” says our Research Editor.
According to one customer, “Too sweet and sickly for me. Could only get through half of it before giving up. Six hours later I still have a sweet chemical aftertaste. Regret buying this. Will look for better alternative.”
“I thought it tasted horrible and no matter how much I mixed it in my shaker it just didn’t blend well. Lumps of powder. Terrible stuff,” said another user.
Lack of Availability – Another Concern
It looks like USN Diet Fuel Ultra Lean is only available to those living in the UK. Therefore dieters from other countries will certainly have a difficult time trying to get this supplement. One person stated, “Where can I buy this?? It doesn’t seem to be available online.”
Another dieter said, “Only seems to sell in the UK. Oh well, on to a different product.”
The intensive research we’ve done has shown if there is one particular facet of a supplement or diet program that is especially bothersome (a painful/difficult exercise routine, bad taste, lack of availability) the odds of prolonged success are not good. This means if USN Diet Fuel Ultra Lean does in fact taste bad to numerous people and is difficult for many dieters to find, this could be a serious dilemma.
The Science – Any?
Like most protein powders, USN Diet Fuel Ultra Lean provides a significant amount of protein per serving. However, we were unable to find any clinical studies that support the claimed effectiveness of this supplement. At DietSpotlight, we need to see solid research that backs up the weight loss.
The Bottom Line: Does USN Diet Fuel Ultra Lean Work?
So, should you run out and buy USN Diet Fuel Ultra Lean? Well, we like that USN Diet Fuel Ultra Lean provides a good amount of fiber and there are some positive comments about it online. But we have some reservations about this supplement because it’s not backed by clinical studies. Furthermore, we’re concerned about this product’s bad taste and lack of availability.
If you’d like to drop more weight, then we encourage you to go with a supplement that is readily available online, contains clinically proven ingredients and comes with excellent customer service.
Among the best products we’ve seen in 2016 is one called Leptigen. Its formula is a proprietary blend of four key ingredients, which have been shown in documented clinical studies to help speed up fat loss and boost metabolism. We can’t pinpoint any talk of negative adverse effects and dieter comments found on the web show people are seeing substantial results.
The makers of Leptigen are so excited about their product they’re offering a Special Trial Offer, which is a positive sign.
