Fat Burner: what's in the formula and what it does
The fat burner is undoubtedly the product about which we receive the most questions at the counter, and around which the most misconceptions circulate. Let's be clear from the start: no formula will melt fat for you. What a burner contains, however, acts on precise mechanisms, which are worth understanding before buying.
What does a fat burner actually contain?
Most formulas in the fat burner section combine three families of ingredients. First, stimulants, with caffeine leading the way, often between 150 and 300 mg per dose: this is the active ingredient whose effect is the clearest and most measurable. Next, plant extracts—green tea, black pepper, bitter orange—which support thermogenesis. Finally, cofactors like chromium, B vitamins, and L-carnitine, whose role focuses on energy metabolism.
One detail that changes everything when reading a label: the ingredient's position in the list and its actual dose. A formula that advertises ten active ingredients often includes nine at symbolic doses. Three properly dosed ingredients are better than ten in trace amounts.

Powder, capsules, or caffeine-free formula: what to choose?
The format is not just a matter of convenience. A powdered fat burner dissolves in a large volume of water, which helps to split the dose and encourage more fluid intake. Capsule burners are easier to carry and dose precisely. If you are sensitive to stimulants, train in the evening, or already drink several coffees during the day, opt for a caffeine-free burner: you'll lose the energizing boost, but you'll sleep.
Among the highly concentrated formulas, Nutrex Lipo 6 Black Ultra Concentrate is one of the historical benchmarks in this category. It is not intended for a first trial: start with half a dose in the morning, never after early afternoon, and assess over three or four days before adjusting.
Does it work?
Here's the honest answer. A burner doesn't create a caloric deficit; it only supports the one you create through diet and activity. For someone whose diet isn't controlled, the measurable effect is close to zero. For someone already in a deficit, caffeine provides available energy for training and a reduction in appetite mid-morning—two real effects that help sustain efforts, which is often the real obstacle.
This is also why we recommend looking at what's on your plate first. Quantity guidelines are compiled in our article on eating a balanced diet without weighing every food, and protein intake, crucial during a deficit period, in our article on daily protein for athletes.

How to use it correctly
- Always start with half a dose for the first three days to assess your caffeine tolerance.
- Never take the last dose after 4 PM: insomnia negates all the product's benefits for recovery.
- Drink more. Thermogenic formulas increase sweating, and mild dehydration reduces performance long before it causes fat loss.
- Use in cycles of four to six weeks, then take a break. Caffeine tolerance develops quickly.
- Do not combine a burner with a caffeinated pre-workout booster on the same day: the doses add up and become difficult to manage.
Precautions and contraindications
Stimulant formulas are not recommended for those with hypertension, heart rhythm disorders, thyroid disorders, during pregnancy and breastfeeding, and for those under 18. If you are on any treatment, even a mild one, consult your doctor or pharmacist before starting: it's a two-minute answer that avoids unpleasant surprises.
None of these products treat anything and none cause weight loss on their own. We prefer to state this clearly rather than let a label suggest otherwise.

Frequently Asked Questions
How long does it take to see results?
The stimulant effect is immediate, from the first dose. Everything else depends on the caloric deficit: with a controlled diet and regular training, the first visible differences usually appear after three to four weeks, and they come from the deficit, not the product.
Should it be taken on an empty stomach?
