Phedra-Cut Ultra XT Review - Does This Weight Control Aid Really Work? Are questionable ingredients and adverse effects deal breakers?

Editor's Review: 3.5 / 5.0
Phedra-Cut Ultra XT Review

I’m obsessed with finding diet products that actually work. Let’s find out if Phedra Cut Ultra XT is one of them. We did one of our intensive reviews, inspecting the side effects, ingredients, clinical studies and overall customer service. We also took the time to read hundreds of dieter responses and user reviews that are posted online. At this point we summarized and condensed all the facts to give you the bottom line.

EDITOR'S TIP: Combine Phedra-Cut Ultra XT with a proven fat burner such as Leptigen for better results.

What You Need To Know

First off, Phedra Cut Ultra XT is a weight-loss supplement contains caralluma fimbriata, bioperine, glucuronolactone, capsicum extract, yerba mate, green tea extract, natural caffeine, citrus aurantium, fucoxanthin, green coffee bean, banaba extract, n-acetyl-l-carnitine, iodotyrosine and l-tyrosine. It should be taken twice a day (2-3 capsules, 30 minutes before meals). However, you should take two days off each week. Put simply, this product claims to boost thermogenesis, increase energy levels and aid with weight-loss.

Phedra Cut Ultra XT was released back in 2008 by USN or Ultimate Sports Nutrition. Some natural ingredients are used and the ingredient label is clearly posted on the company website, but read on…

Ingredients – “Clinically Proven Issues?”

The first concern we had with Phedra Cut Ultra XT ingredients was that they may cause some side effects. “We immediately noticed that the formula contains citrus aurantium, which has synephrine in it, which can result in accelerated heart rate and increased blood pressure,” says our Research Editor. It is important to note that this ingredient has been clinically tested and proven to cause adverse reactions in some users, especially when used with caffeine.

According to one user, “I bought this product last year and after 2 months I noticed an increase in my blood pressure.”

“I recently bought Phedra Cut and have been taking it in the morning and in the afternoon. 2 days of being on them and I’ve been nauseous and my tummy hurts,” said another customer.

Scroll below for one of the best products we’ve seen over the last year.

Side Effects – “Another Concern?”

It’s evident that Phedra Cut Ultra XT can lead to some adverse effects, which is a concern. One customer commented, “I have been using Phedra-Cut Ultra XT for the last 4 months. What is now evident on me is that my tummy is bloating and I have low libido and sex drive.”

Another user stated, “I feel HOT. My head feels hot, and last night when I trained I sweated like never before. Is this normal? What is causing this HOT feeling in my head?”

Our research has proven if there is a particular facet of a pill or program that is very problematic (terrible taste, adverse reactions, poor ingredients) the likelihood of lasting weight-loss is slim. In other words, if Phedra Cut Ultra XT does lead to side effects in some people, this could be a problem.

The Science – “Solid?”

Here at DietSpotlight, we like to see documented clinical results that supports the diet product in question. In regards to Phedra Cut Ultra XT, we could not pinpoint any scientific research or clinical studies. Unfortunately this is a red flag.

The Bottom Line – Does Phedra Cut Ultra XT Work?

Now the moment you’ve been waiting for: our bottom line on Phedra Cut Ultra XT. Well, we like that it contains some natural ingredients and it can be used by women and men alike. Then again, we have reservations with it because it’s not backed by any real science. Also, we’re concerned about the ingredients that may cause side effects.

If you’d like to slim down and drop more pounds, we recommend you go with a diet supplement that does not use dangerous ingredients, is backed by solid scientific studies and does not lead to side effects.

Among the best products we’ve seen in 2016 is one called Leptigen. This supplement uses a blend of four important ingredients, which have been shown in documented clinical research to help enhance fat loss and elevate metabolism. We can’t pinpoint any talk of unpleasant side effects and dieter comments found online indicate people are seeing excellent results.

Plus, the makers of Leptigen are so positive about their product they’re offering a Special Trial Offer, which is a good sign.

Phedra-Cut Ultra XT fat burner is designed to improve metabolism and speed up weight loss. The product description includes a complete ingredient list, but we are concerned about the product name. The word Phedra comes from the ingredient ephedra. If this product contains ephedra it is illegal for sale in the United States based upon the ban established by the FDA. The FDA now regulates all sales of ephedra.

List of Ingredients


  • Caralluma Fimbriata
  • Capsicum Extract
  • Citrus Aurantium
  • Fucoxanthin
  • N-Acetyl-L-Carnitine
  • L-Tyrosine
  • Iodotyrosine
  • Diidotyrosine
  • Banaba Extract
  • Green Coffee Bean
  • Natural Caffeine
  • Green Tea Extract
  • Yerba Mate
  • Glucuronolactone
  • Bioperine

Product Features

The USN-XT proprietary blend is packed with stimulants. Green coffee bean is commonly used to replace garcinia cambogia. Green coffee bean is a source of caffeine. Natural caffeine is the second ingredient in the formula. Of course, natural caffeine is a source of caffeine. Green tea extract is a third source of caffeine, but this time it comes in a proven metabolism-boosting ingredient. Yerba mate is the final caffeine source.

When you pack that many stimulants into one supplement, you have to attempt to reduce blood pressure rise that will inevitably occur. Phedra-Cut Ultra XT contains various forms of tyrosine. Tyrosine is thought to control blood pressure naturally.

Bioperine is added to increase the absorption of the other ingredients in the formula. Banaba helps control blood glucose response and hunger and Caralluma Fimbriata has some positive clinical studies for use as a diet supplement.

  • All ingredients are listed online in label form.
  • The product contains several proven ingredients.
  • May help control hunger and increase energy.


  • May contain too much caffeine for some dieters - 208 mg.
  • Likely to cause negative side effects if the dieter does not usually take caffeine.
  • May cause increase heart rate, increased blood pressure and jitters.


Overall, Phedra-Cut Ultra XT is a good supplement, but there are far too many stimulants in the formula. Most dieters are not used to taking supplements with heavy stimulation. There is a good chance the dieter will notice nausea, jitters and shakes when taking this product. The effects will be even worse if the dieter drinks caffeinated beverages with the formula. If you currently suffer from high blood pressure or heart problems, this supplement is not safe. The L-Tyrosine may decrease blood pressure slightly, but not enough to reduce the overall effect.

We suggest using a diet supplement with proven ingredients like green tea, caffeine and chromium and not multiple supplements.

    Is it possible to use the product if you are suffering from stomach ulcers

    We wouldn’t recommend it unless otherwise suggested by your doctor.

    I’ve been taking Phedra Cut Lipo XT in combination with CLA now for about a year! I cannot speak for the old formula (the one being reviewed) What I can say is that there is a reason why newer formulas were made!
    I give myself a break on a weekend (as suggested on the pack) and once I finish a bottle, I detox for about a month… As in I take nothing! I gym 4 to 5 times a week and the results are phenomenal! Prior to this, I would gym, eat relatively clean…ish (I do admit to having a sweet tooth), but I didn’t have that toned, defined look I wanted! Until the supplements! If taken properly, 30 or so min before meals and with lots of water throughout the day AND most importantly with excercise, you will see results!
    As with any tablet, you will have some side effects, but give it time, most side effects disappear. And if they don’t, and they are unbareable then the product is simply not for you… What works for one person might not necessarily work for another…
    I also enjoy the energy boost it gives me throughout my day…

    Usually it takes around a month to see results from a diet; sooner or later depending on the individual. Stick it out, if at the end there’s nothing try browsing our reviews for an alternative.

    This product decreased my appetite and reduced my cravings, it did help me shed large amounts of weight in relatively short periods of time. However I do not think it is safe for long term use.

    I have only been taking phedra cut xt for two weeks. I did get a slight rash around my eyes but it has got worse and worse and now that I have stopped it has started to go away.



    You will but slowly

    I’ve only been taking Phedra-cut for 3 days with my morning workout and lunch. I have the occasional stomachache but it pass after a dump or flatulence. It works well with a morning workout but I think 4 a day is too high a dosage after reading the bottle again it actually recommends starting off with a smaller dosage of 1 or 2. I think I’m going to lower it to 2 a day to make the course last longer and see if the pain subsides. -Lookout for my next post in a week if you want to know the result-



    I started the USN 12week challange today, I have taken CLA and phedra cut Lipo xt – seems to have made me feel “on edge” and shakey.. This normal? I have taken 2 today.



    this products is safe if you drink not less than 2 litres of water per day I asure you
