What is Phenta XT?

  • Caffeine Anhydrous
  • Vitamin B6
  • Vitamin B12
  • Choline Bitartrate

Phenta XT Ingredients – “Questionable?”

The first concern we have is with Phenta XT ingredients. According to our Research Editor, “This diet supplement contains ingredients such as synephrine (taken from bitter orange) and caffeine anhydrous. When combined, these components can cause adverse reactions.” [2]

The National Institutes of Health states, “Bitter orange, particularly when taken with stimulants such as caffeine or caffeine-containing herbs, increases the risk for high blood pressure, fainting, heart attack, stroke, and other severe side effects.” [3]

Then again, one user said, “Good product. Knocks out my appetite. [4] Gives me more energy.”

Another commented, “Great energy from this. Good for in the morning.”

Side Effects – “Watch Out”

Another issue is Phenta XT side effects. Some users have reported jitteriness, headache, anxiety, nausea, heart palpitations and insomnia from the ingredients. [5] In fact, one person stated, “Don’t like it. Makes me very wired and jittery. My heart races. I can’t get to sleep at night.”

But, a different customer had this to say, “Not bad. It will give you a jolt. Reduces my food cravings some.”

“It does take my appetite down a notch. I like that. Definitely feel the stimulants in it,” mentioned another.

The research we’ve conducted has shown if there’s some specific part of a diet pill or weight-loss supplement that is quite burdensome (dangerous ingredients, side effects, poor BBB rating) the odds of real results that really last are not good. This means if Phenta XT does in fact cause unpleasant adverse reactions in a lot of people, this could be problematic.

The Science – “Is It Solid?”

Well, we did not find any clinical studies presented with Phenta XT capsules. However, this formula does contain some green tea and caffeine. These ingredients have been shown to help with fat loss. [6] However, the side effects this supplement can cause may outweigh any benefits.

What Users Are Saying

“This product is excellent. It gives you energy but it doesn’t make you jittery. I’ve ordered it twice and want to keep a supply of it. It’s not the”


“I can’t take this due to side effects. Was not a good fit for me.”

The Bottom Line – Does Phenta XT Work?

So, should you race out to the store and buy Phenta XT pills? Well, first off, we like that this product is easy to use/take anywhere. Also, we did see some positive comments posted on the web. Then again, we have some reservations about this formula because it contains a dangerous ingredient combination. Also, we’re definitely concerned about the side effects some users have reported.

If you’d like to drop more pounds, then we suggest you select a product that contains safe ingredients for weight-loss, does not lead to any harsh adverse effects and gives you a lot of bang for your buck.

Among the best products we’ve seen this year is one called Dietspotlight Burn. This powerful formula contains four key ingredients. Some of which have been shown in documented clinical studies to help accelerate fat loss and spark metabolism. We have not spotted any user complaints. Also, the comments posted online express people are seeing real results.

The makers of Dietspotlight Burn are so certain of their product they’re offering a Special Trial Offer, which is a good sign.

6 Phenta XT Reviews

  • 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.

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

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

    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.

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

    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.

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

    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.
