USN Phedra-Cut Ultra XT Review

USN Phedra-Cut Ultra XT is a weight loss supplement that is marketed primarily as a safe and effective ‘advanced fat loss activator’.

The supplement is manufactured by USN, a South African company who manufacture and sell a range of supplements.

USN Phedra-Cut Ultra XT Facts

  • Manufactured by USN
  • 30 or 120 capsules per bottle
  • Appears to be only available in South Africa

With no individual ingredient quantities listed it is difficult to establish the actual strength of this product, and so its effectiveness and the likelihood of side effects occurring are unknown.

However, there are some ingredients used in the product that could be effective at aiding weight loss, if they are used in the correct quantities. Bitter orange is a stimulant that increases the body’s metabolic rate, although its safety is debated and it can cause numerous side effects. The Mayo Clinic states that the risk of developing unpleasant and even dangerous side effects is too high to justify using bitter orange extract.

How to Take USN Phedra-Cut Ultra XT

Take 2-3 capsules 2 times daily, 30 minutes prior to meals (preferably breakfast and lunch).
If training early morning, take 2-3 capsules prior to workout, and follow with breakfast directly after training.

Due to high stimulant content Phedra-Cut Ultra XT is not recommended after 4pm.

Take Phedra-Cut Ultra XT for 5 consecutive days of the week and stop use for 2 days before continuing again (2 off days).

Caffeine is another stimulant that increases the metabolism, but its effects are much less dramatic. Bioperine increases the absorption of caffeine and other compounds from the digestive tract into the bloodstream; this effectively makes the doses used higher, but can increase the chances of side effects occurring and increase the chances of accidental overdose from prescription medication.

Green coffee bean currently has no strong clinical support as the main study available was found to be fraudulent. Yerba mate and green tea both have clinical evidence linking them with some potential weight loss.

USN Phedra-Cut Ultra XT Concerns:

  • No money-back guarantee
  • Short, strict returns policy- 7 days
  • No ingredient quantities provided

Banaba may help to regulate blood sugar levels, which could theoretically help to regulate sugar crashes and sugar cravings. Fucoxanthin appears to contribute to an increased rate of weight loss over time, but it is unclear how it works.

Carnitine is often touted as a fat burner, and tyrosine as an appetite suppressant, but there is little evidence to support either.

Caralluma Fimbriata may work as an appetite suppressant but it takes time to build up in the body and for effects to be noticed, and so should be used as a long-term supplement.

What Does USN Phedra-Cut Ultra XT Claim To Do?

The manufacturers have provided the following description of the supplement and its supposed benefits:

The USN Phedra-Cut Ultra XT is an advanced fat loss activator, consisting of a synergistic blend of natural ingredients, which have all proven to assist in safe and effective weight-loss.

Benefits of USN Phedra-Cut Ultra XT:

  • Increased fat burning activity (incl. abdominal fat)
  • Blood glucose regulation (which may also eliminate cravings)
  • Reduced carbohydrate absorption
  • Appetite suppression
  • Reduced glucose production in the liver
  • Reduced fat accumulation
  • Inhibit fat cell formation (Anti-adipogenic activity)
  • Mood and mental acuity enhancement
  • No estrogenic interactions
  • Anti-oxidation during fat breakdown
  • Energy boosting

Does USN Phedra-Cut Ultra XT Work?

The overall rating of USN Phedra-Cut Ultra XT on the Supplement World website is high, but the majority of the customer reviews that have not been left are not viewable.

There are numerous ingredients used in USN Phedra-Cut Ultra XT that could help to increase the rate of a dieter’s weight loss, provided they are present in adequate quantities. Bitter orange, yerba mate, caffeine and green tea all have supporting clinical evidence to suggest that they could increase the body’s metabolic rate and increase thermogenesis. Fucoxanthin and Caralluma Fimbriata could also aid weight loss, provided the supplement is used regularly in the long term, as both ingredients do take some time to provide noticeable effects.

Banaba and green coffee bean currently have little to no clinical support linking them with weight loss, but in theory banaba could regulate blood sugar levels to help reducing cravings for snacks. This could theoretically help consumers to stick to their diet.

Overall, USN Phedra-Cut Ultra XT could theoretically help to increase the consumer’s rate of weight loss, but without knowing the ingredient quantities used in the diet pill, it is impossible to establish just how effective or safe it actually is.

What Are The Ingredients of USN Phedra-Cut Ultra XT?

The ingredients used in USN Phedra-Cut Ultra XT are listed below.

The product uses several proprietary formulas, and so no individual ingredient quantities are provided. The doses that are listed are per serving of three capsules.

M-phR Multi-Phase Proprietary Blend 1304 mg

  • Caralluma Fimbriata (30% extract): Although touted as an appetite suppressing weight loss aid, this plants appetite suppressing qualities seem to take time to manifest (a month of use or more), and even when appetite was reduced in studies, no weight loss has been observed. This may be because of the relatively short period that the clinical studies observed participants for.
  • Bitter Orange: Also known as citrus aurantium, this ingredient contains synephrine. A review of numerous studies concluded that use of synephrine resulted in an increase to the participants resting metabolic rate and energy expenditure, and moderate weight loss was seen in studies lasting over 6 weeks. However, there are some concerns about its safety being under-researched and the numerous side effects that have been associated with it.
  • Fucoxanthin (as Laminaria japonica 10% extract): A few studies have shown a connection between long term consumption of ‘A daily dosage of 2.4-8mg fucoxanthin’ and weight loss, although there are currently several theories about what mechanism causes this weight loss. Weight loss is not seen quickly with this ingredient.
  • N-Acetyl-L-Carnitine: There is some evidence that supplementation of acetyl-l-carnitine can reduce body fat, although the strongest results were seen in the elderly. The ingredient also boosts energy levels, and is used to treat fatigue.
  • L-Tyrosine: Some people use Tyrosine as an appetite suppressant, but there is little clinical evidence that it is effective for this use. Large doses of tyrosine may be useful for increasing alertness, especially in people who are sleep deprived.
  • Lagerstroemia speciosa (banaba leaf) (1% Corosolic acid): This plant extract may help to lower blood sugar levels, which may help with weight loss efforts.

USN-XT Proprietary Blend 675 mg (of which total caffeine 208 mg)

  • Green Coffea arabica (Green Coffee Bean) (45% Chlorogenic acid extract): Contains caffeine. Whilst it was thought that this ingredient was a significant aid in weight loss, the relevant research has been discredited as it was fraudulent. Currently there is no evidence that it aids with weight loss more than any other source of caffeine. See our article for more details:
  • Caffeine Anhydrous: Numerous studies have shown that caffeine boosts energy levels and alertness, as well as mildly boosting the metabolism. The effects shown in studies are small, and some studies are inconclusive.
  • Cameillia Sinensis (green tea) (45% EGCG Extract): Green tea is high in a group of antioxidants called catechins. Studies have suggested that catechins increase thermogenesis in the body, whilst caffeine increases energy expenditure by boosting the metabolism slightly for a few hours.
  • Ilex paraguariensis (Yerba mate) (25% Xanthin extract): There is diverse clinical evidence to support the use of this plant for weight loss, as it stimulates the central nervous system and increases the metabolic rate. It is also a source of caffeine, and so should increase energy levels. Read our full investigation for more information.
  • Bioperine [95% piperine extract of fruit of Piper Nigrum L. (black pepper) or Piper Longum L. (long pepper)] 5 mg: This patented Black pepper extract is used for increasing the bioavailability of nutritional compounds. In other words, it increases the amounts of nutrients that are absorbed into the body in the digestive tract. It may also increase the absorption of various drugs, which may lead to potential side effects.

Does USN Phedra-Cut Ultra XT Have Any Side Effects?

There are numerous ingredients used in USN Phedra-Cut Ultra XT that could cause a wide range of side effects.

Side effects associated with the use of Bitter Orange extracts include increased heart rate and increased blood pressure, heart palpitations, fainting, and even heart attack and stroke in healthy patients. The Mayo Clinic has recommended avoiding use of Bitter Orange extracts because in their opinion, the risk of using the product is not worth the pay-off of any potential weight loss. The effects of synephrine and other bitter orange extracts are enhanced when combined with caffeine.

There are several ingredients in this diet pill that contain naturally occurring caffeine, including green tea, yerba mate and green coffee bean. Caffeine is also present as a separate ingredient. Side effects of caffeine can include headaches, increased heart rate, increased blood pressure, heart palpitations, increased urination, dehydration, jitteriness, dizziness, and insomnia. Green tea may also cause constipation.There is also an amino acid in Green Coffee Bean called homocysteine that is associated with an increased risk of heart disease.

Caralluma Fimbriata might cause some side effects such as stomach upset, intestinal gas, constipation, and stomach pain.

Tyrosine is generally well tolerated but can cause some side effects such as nausea, headache, fatigue, heartburn, and joint pain.
