What does this dietary supplement contain?
It contains only natural active ingredients, including green tea and guarana. It is sold in a pack with C-Konjac, a natural appetite suppressant made from konjac (a plant native to Southeast Asia).
Note that this is not a miracle pill; you cannot lose weight sustainably without changing the structure of your daily diet. However, this kind of supplement can help, especially considering its effects on satiety.
Here is the list of ingredients and the composition for 2 capsules (daily dosage):
- Green tea (extract – 460 mg): rich in caffeine and catechins, which have fat-burning properties
- Guarana (extract – 300 mg): stimulates metabolism and is energizing for the body and mind
- Kola (powder – 80 mg): a nut rich in caffeine and theobromine (like cocoa), energizing
- Tabashir bamboo : bamboo rich in natural silica
- Pullulan: a substance obtained from the fermentation of tapioca, used in the composition of capsules
- Konjac: a natural appetite suppressant that has a significant effect on satiety
2 Brulafine capsules contain a total of 42.20 mg of caffeine.

\”Fat burner\”: what does the science say?
Very few scientific studies have managed to demonstrate the “fat-burning” potential of certain foods. To date, only green tea and caffeine have proven their benefits during a weight-loss diet according to a meta-analysis published in 2011.
Another 2012 study from Oregon State University tested several hundred fat-burning products, and the effective products produced weight loss of up to 3 kg compared with the placebo group.
The effect of caffeine on weight loss is the most well-documented.
On the one hand, it makes us more alert and more motivated to exercise and to stick to a diet.
On the other hand, it stimulates lipolysis, i.e., the release of fatty acids, by increasing energy hormones (epinephrine and norepinephrine).
Finally, it increases the number of calories burned at rest and during activity. This is called thermogenesis.
Regarding green tea, numerous studies exist. One of them, conducted in 2002, showed a 4.6% weight loss and a 4.48% reduction in waist circumference thanks to the consumption of green tea extract.
Guarana has also been extensively studied by scientists: several studies have demonstrated its usefulness for weight loss.
All studies generally agree on one point: the fat-burning effect of caffeine or green tea supplements only has a real impact when their consumption is paired with physical exercise.

Customer reviews
Brulafine has a rating of 4.2 out of 5 on the review platform Avis-Vérifiés. Negative reviews are related to undelivered packages or to limited visible effectiveness on weight loss. Note that customer service responds to each of these negative reviews, which is rather reassuring.
Brulafine has a rating of 4.1 out of 5 on Google, but these reviews are generally less reliable because they are more easily manipulated.
Our review of Brulafine
Brulafine is part of the large family of fat burners, in which it is not always easy to find your way. Here, it’s primarily the high caffeine content that helps with weight loss.
The ingredients used are among the most scientifically recognized natural fat burners, and should therefore have an effect on weight. But in any case, you should maintain a balanced diet and exercise alongside.
The advantage of a supplement such as Brulafine is that it is completely natural.
It is not a medicine per se, so it will not have the same effect as fat-burning medications sold in pharmacies. But this may reassure some, as its consumption therefore presents no risk.
On the negative side, we would have liked an organic certification for the plant extracts used. Also, there is little transparency about the company Castalis and its team: we would like to know a little more!
Finally, we note that the price is a bit high (€49.70 for one month: 1 box of Brulafine, 1 box of C-Konjac), but this is often the case for this type of supplement. If you take a 3-month pack the price is €45 per month, and this is before the 10% discount you’ll get with our promo code (“DARWIN10“).
At the time of your order, you will get one month free of an online weight-loss coaching app. Remember to cancel this option before the end of the month if you do not want to subscribe.
