In the bottom line, we also went over the supplement’s side effects mentioned in customer reviews and ingredient combinations to see if this one is worth the price.

How Did Phenta XT Start?

Phenta XT is the brainchild of GeneTech Pharma Labs and a Pakistan-based pharmaceutical company that distributes globally. In addition to pharmaceuticals, GeneTech Pharma Labs also distributes hospital supplies and specialized products, like vaccines and supplements. The company has a strong mission statement.

While striving to maintain a physician-centric business model, they focus on goals like being grateful, being honest, and being resourceful. On the website, the company explains that they uphold values that reflect diversity, innovation, integrity, and compassion to achieve the best results.

Unlike other supplements that require taking up to three pills throughout the day to achieve less effective results, Phenta XT only needs to be taken once daily because of its extended-release mechanism.

People taking this supplement may see a reduction in appetite and carb cravings, but skip the late-day fatigue that often occurs with other supplements. Another benefit GeneTech Pharma Labs had in mind when creating Phenta XT was the claimed absence of jitters, which is a common side-effect seen while taking other products that state they work the same way.


Phenta XT Ingredients

The ingredients used in Phenta XT are what make it an amazing, energizing, weight loss supplement, according to the manufacturers.

Phenta XT ingredients are divided into four categories, including the Energy Matrix, Thermos Matrix, Neuro Matrix, and “other” ingredients.

Phenta XT Energy Matrix

Phenta XT contains an Energy Matrix containing:

  • Caffeine
  • Green Tea Extract
  • Coco Bean Extract
  • Synephrine
  • Hordenine
  • Hoodia Gordonii
  • Beta-Phenylethylamine
  • Octopamine


Caffeine aids in weight loss in several ways. Notably, it increases metabolism, which can increase fat burning in the short term. It has also been shown to suppress your appetite.

According to the Journal of the International Society of Sports Nutrition concluded, consuming a supplement containing caffeine before working out could help to improve weight loss results.

Phenta XT Ingredients green tea

Green Tea Extract

Green tea has long been known to aid in weight loss. It contains the appetite-suppressing qualities of caffeine.

All tea is made from the same plant, Camellia sinensis, but green tea is less oxidized than black tea. Molecular Nutrition & Food Research found that drinking 3-4 cups of tea per day can reduce body weight.

Cocoa Bean Extract

Cocoa Extract contains theobromine. Theobromine is thought to help elevate your mood, according to the British Journal of Clinical Pharmacology.


This substance is also used for increasing metabolic rate. This can reduce the chances of fat being stored in the body in the fat burner formula. Another study published in the British Journal of Clinical Pharmacology found synephrine to increase fat oxidation in adults.


Hordenine is a chemical thought to promote weight loss. It can be easily obtained from barley and is a common substance in many weight loss supplements.

Hoodia Gordonii

While some information relating to effectiveness is anecdotal; there’s no research showing hoodia is an effective appetite suppressant.


Octopamine is claimed to have little fat burning properties. The ingredient is banned by the World Anti-Doping Agency (WADA) because of its stimulant properties, according to the British Journal of Pharmacology.

Theobroma Grandiflorum (Cupuacu)

This member of the cocoa family is thought to be abundant in health benefits. It is rich in vitamins, minerals, and antioxidants. It also contains pectin fiber and caffeine.


Niacin is a vitamin which helps the body convert food into energy. According to the National Institutes of Health, niacin is an important part of the diet that can be found in many common foods.

Vitamin B6

Vitamin B6 is a necessary vitamin that aids in energy and metabolic function, according to The Journal of Nutrition.

Vitamin B12

Vitamin B12 is necessary for weight loss and has been linked to energy and appetite, states the journal Nutrients.

Phenta XT claims to reduce your weight as well. It also claims to help increase your metabolism, which in turn might help you lose weight.


Phenta XT Safety

While Phenta XT total nutritional capsules claim big results as a weight loss and fat burning instrument, it does not support its claims with the help of any scientific studies.

In addition to its lack of providing safety and reliability proofs, the supplement also contains some ingredients which are harmful for human consumption. This calls into question the reliability of the product and its safety for consumption.


How To Take Phenta XT

Manufacturers of Phenta XT total nutrition suggest that taking one capsule of Phenta XT fat burner per day is sufficient. In fact, they warn against consuming more than 1 of the Phenta XT 12-hour energy dieting formula pills in a day.

11 Phenta XT Reviews

  • My "Go To"
    Ingrid (Verified Purchase)

    This is my “Go to” pill. I am very sensitive to high levels of caffeine and even if I have a coffee after taking one of these, I still feel fine. It’s an “All day energy” for sure. Even, no spikes or lulls.

    It really knocks out my appetite (even with that little monkey brain is trying to convince me to eat, my stomach says “NOPE, not today”.). I do notice though, if I am really needing some nutrition, my body seems to override this pill and I will eat as though it wasn’t effective, but on other days, after having enough food in me for the week, I can take on on a day where I don’t really want to eat much or at all and it works like a charm. I’ll select certain days in which to take one and the bottle can last me for months this way. I like to use them to kick-start a water fast (supplemented with minerals if the fast is longer than 2 days).

    I would say that for me, it lasts longer than 12 hours, so if you want your sleep, take them only in the morning, first thing, before you do ANYTHING else.

  • Anonymous (Verified Purchase)

    Have anyone experience loss of sex drive?

  • Not for me

    It has caused me to have extremely high blood pressure. My blood pressure is always perfect!
    hope to get this crap out of my system and never taking it again.

    • Victoria (Editor)

      Hi Krista, maybe it was the caffeine content in Phenta XT.

      Have you ever looked into caffeine-free weight-loss products? Dietspotlight Burn offers that option, you should check it out.

  • Corina (Verified Purchase)

    Wondering if it causes you to be depressed or mood change? I noticed I’m kinda down but it does work for weight loss

    • Leigh Edwards

      It caused me to have depressed moods and anxiety.

  • Probably not the pill for you
    S (Verified Purchase)

    Made me feel like hell. Jittery, nauseous and anxious. I had liked the idea of some of what’s in this stuff. It seems as though there’s a bunch of really good things, but it’s a little much in terms of what you actually get out of it. Feels like an amphetamine.

  • Killyback
    Tomasz Zwierzyński (Verified Purchase)

    The best FAT killer

  • Not real sure about it.
    Kaitlyn (Verified Purchase)

    I took it around noon today with a meal, I loved the boost of energy but it did kill my appetite I didnt eat again until 5ish and I couldn’t even get down half a piece of pizza before it was just making me feel nauseous then about an hour later I was throwing that up. Looking for Any kind of helpful tips to make this a smoother process? Not a big fan of puking.

      Have you tried drinking plenty of water if the side effects are that bad, to help flush it out of your system?

  • BEWARE! Not like original formula!!
    Amber (Verified Purchase)

    I used to the the older version of it in the black capsule. I never had any problems with it. I took my first dose yesterday and YIKES! I had severe and long lasting heart palpations, nausea, dizziness, sudden onset of extreme sleepiness ( I feel asleep sitting up in Starbucks drinking a pineapple tea!), very jittery, weird salivation, and I fell down when getting up off the couch slowly.
