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

Editor's Review: 3.5 / 5.0

phedra-cut-ultra-xt-product-imageI’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

Phedra Cut Ultra XT is a weight loss supplement made by USN or Ultimate Sports Nutrition. It should be taken twice a day (2-3 capsules, 30 minutes before meals). However, you should take two days off from this supplement each week. Put simply, this product is claimed to boost thermogenesis, increase energy levels and aid with weight loss. The ingredients used in Phedra Cut Ultra XT are as follows; 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.

Phedra Cut Ultra XT was released back in 2008 and this supplement can be used by both women and men. Some natural ingredients are used in this product and the ingredient label is clearly posted on the company website, but read on…

Dangerous Ingredients – Concerning?

“We immediately noticed that Phedra Cut Ultra XT contains Citrus Aurantium, which has Synephrine in it. Synephrine can result in accelerated heart rate, increased blood pressure, heart attack and even stroke,” says our Research Editor.

According to one user, “I bought this product last year and after 2 months I was diagnosed with severe high blood pressure. I followed all instructions. This product is a death trap.”

“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 vomiting hectically and my tummy hurts,” said another customer.

Adverse Effects – Another Concern

It’s evident that Phedra Cut Ultra XT can lead to some adverse effects, which is a serious 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. I struggle to get an erection.”

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 weight loss pill or diet program that is very problematic (terrible taste, serious adverse effects, dangerousingredients) the likelihood of lasting weight loss is slim. In other words, if Phedra Cut Ultra XT does lead to side effects in numerous people, this could be a major problem.

The Science – Solid?

Here at DietSpotlight, we like to see documented clinical results that support 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 Phedra Cut Ultra XT contains some natural ingredients and it can be used by women and men alike. Then again, we have some qualms about it because it’s not backed by any real science. Also, we’re concerned about its dangerous ingredients and 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 harsh side effects.

Among the best products we’ve seen in 2015 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.

    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.
