Xenadrine XT is a new fat burner from the popular Xenadrine product line. The supplement claims to be perfect for extreme individuals who want to increase energy, smash through those weight loss plateaus and get more out of every repetition in the gym. Behind these claims is a heavy dose of caffeine and some green coffee bean extract. We expected more out of Xenadrine XT, but when a product uses the word extreme it usually means extreme caffeine.

List of Ingredients


  • Caffeine Anhydrous
  • Green Coffee Bean Extract
  • Sage Leaf
  • L-Theanine
  • Yohimbine Bark
  • Rhodiola Root Extract

Product Features

Caffeine anhydrous or powdered caffeine is one of the more common stimulant ingredients used in fat burners today. The amount of caffeine added to each supplement varies widely from about 50 mg to more than 300 mg per serving. In the case of Xenadrine XT, the dieter is taking 270 mg of caffeine per serving with multiple servings suggested each day. The instructions for Xenadrine XT suggest the dieter start out with one capsule twice daily – total caffeine intake of 270 mg per day split into two doses of 135 mg. That serving size is upped to two capsules taken as one dose per day – total caffeine intake of 270 mg as a single dose. By the 4th day the dieter should be taking two capsules twice daily – total caffeine intake of 540 mg.

This may not sound like a lot of caffeine, but take into consideration that the average over-the-counter no-sleep pill contains 200 mg of caffeine. Taking Xenadrine XT at the maximum dose is like taking a no-sleep supplement nearly three times in one day. There are bound to be negative side effects like jitters, shakes, nausea and sleeplessness.

The remaining ingredients are no clinically proven to have any impact on weight loss or energy, so Xenadrine XT relies solely on the power of massive amounts of caffeine to achieve all the claimed results.

  • Caffeine is a common weight loss ingredient.
  • In proper amounts caffeine can increase metabolism without causing side effects.


  • Dieters should not take in additional caffeine while taking Xenadrine XT.
  • Negative side effects are possible when taking the supplement.


Xenadrine XT is nothing more than a caffeine pill with a few other ingredients thrown in for good measure. In terms of weight loss and energy the caffeine is the only proven ingredient, but the amount the dieter will take at full dose is extraordinary. If you are sensitive to caffeine, skip Xenadrine XT.

    I just don’t think Xenadrine XT is “nothing but caffeine”. It’s very powerful and the effects I have felt from taking it for over a year are similar to Ephedrine. In fact, I stopped looking for Ephedrine because of the similar effects of this pill. I think the other ingredients do factor in to the overall powerful stimulation. One thing I will say, however, is the palpitations are severe (in my case) and I have stopped using them. I think my heart has gone bad but that is mostly due to years of Ephedrine abuse and has almost nothing to do with this effective stimulant. I am just trying to warn others who may have existing heart issues. Thanks.
