Key facts

• ›Five actives, each printed on its own line, per capsule and per two-capsule serving. No proprietary blend.
• ›Other ingredients: hypromellose (the vegetable capsule shell), silica and magnesium stearate.
• ›The green tea extract is standardised to 98% polyphenols, 45% EGCG and 75% catechins.
• ›Research amounts run higher than the panel for two actives. A third, Capsimax, cannot be judged because its capsaicinoid share is not printed.
• ›Bottle: 60 capsules. That is 60 servings at one capsule or 30 servings at two.
• ›Two direction sets exist, one on the sales listing and one on the bottle. The bottle is the one to follow.

What is in a Burn XT capsule?

Start with the panel, because every other fact on this page comes from it. The panel prints two columns. One column is for a single capsule. The other is for the two-capsule serving that most marketing quotes.

Under the panel sits the other-ingredients line: hypromellose, silica and magnesium stearate. Hypromellose is the plant-based shell. Magnesium stearate is a flow agent that keeps powder from sticking to the machines, and silica sits beside it on the same line. Capsimax and BioPerine are licensed brand names, and both marks are printed on the panel.

“Daily Value: not established” appears on all five rows. No reference intake exists for these, so no percentage can be printed. It is a rule about labels and says nothing good or bad about the ingredient.

What does each Burn XT ingredient do?

One line each, in plain words. The research behind each one is small in effect, and none of it was done on this finished capsule.

• Acetyl-L-Carnitine HCl, 700 mg. The body already makes carnitine. Its job is to carry fatty acids into the cell parts that use them for fuel. Trials on weight found small average changes, and the effect shrank in longer trials.
• Green tea leaf extract, 450 mg. It concentrates the leaf’s catechins. Paired with caffeine, it raised 24-hour energy use by about 4% in one well-known 1999 study.
• Caffeine anhydrous, 270 mg. This is the ingredient you will feel. It raises alertness within an hour. Anhydrous just means the water has been removed.
• Capsimax cayenne pepper fruit extract, 50 mg. A branded, coated pepper extract. Pepper compounds raise energy use for a few hours after a dose.
• BioPerine black pepper fruit extract, 5 mg. It is a helper. It slows some of the enzymes that clear other compounds, so they stay in the blood longer.

If you want the long version for the first three, read our posts on 270 mg of caffeine, acetyl L-carnitine at 700 mg and green tea extract and your liver. The pepper pair has its own post: what Capsimax and BioPerine are.

How do the Burn XT amounts compare with the research?

A label can list the right ingredients and still use smaller amounts than the studies did. This table sets the panel beside the typical research amounts. A gap does not prove that nothing happens. It is a reason not to borrow the trial result.

The 200 mg of EGCG is not printed. It is arithmetic from the printed standardisation: 450 mg of extract at 45% EGCG. The same sum on 75% catechins gives about 340 mg.

What is not in Burn XT?

Absence is harder to prove than presence, so this list is read straight off the panel and the other-ingredients line.

• No proprietary blend. Every active has its own amount.
• No yohimbine, no synephrine and no DMAA. The only stimulant is caffeine.
• No gelatin. The shell is hypromellose, so the capsule is plant-based.
• No sugar, sweetener, sugar alcohol or flavouring.
• No garcinia, raspberry ketone or forskolin.

The product is not a gummy, a powder or drops. It is a vegetable capsule.

What do the label directions say about dosage?

Two sets of directions exist, and they differ. The sales listing gives one line. The bottle’s back label gives a build-up. Where they differ, follow the label on the bottle.

The label adds three rules. Take it with food, keep it six hours away from sleep, and do not mix it with other caffeine. For a deeper read, see how to take Burn XT.

The back label also carries a 60-day use direction, paired with diet and exercise. That is a direction for use, not a promise of any result.

What does the Burn XT label leave out?

A panel is a list of what the maker says is inside. It does not prove it. Four gaps are worth knowing.

• The capsaicinoid share. The Capsimax row gives 50 mg of extract but not how much of it is the active part. This is the one real omission on the panel.
• The piperine percentage. It is not printed, so it cannot be treated as a label fact.
• Where it was made and tested. A panel states composition only. A lot number links a bottle to a production run, but it is not a test result.
• Third-party testing. No independent finished-product testing mark appears on the artwork.

No trial has been run on the finished capsule. The research named on this page covers the ingredients one at a time.

Frequently asked questions

Where do these facts come from?

Our view

Our view is that this is a clearer label than most in its group. Every active has a number, and the green tea extract even prints its standardisation. That is rare, and it lets you do your own sums.

The same clear label also shows the weak spots. Two amounts are below their research, and the Capsimax share is missing. Read it the way you would read any label: find the serving size first, then the stimulant amount, then the gaps. For more on that habit, try reading a two-column panel.

Burn XT is a dietary supplement and it is not FDA approved. If you take medicine or have a health condition, show the caffeine and piperine figures to a pharmacist before you start.
