Understanding the science

Let’s have a look behind the scenes to help you understand how some of our bestsellers work.

NightBurn EXTREME – the nighttime fat burner

NightBurn XXL contains Garcinia cambogia is one of our beloved ingredients. Its weight-loss enhancing active ingredient hydroxycitric acid (HCA) is an appetite reducer, and it prevents the storing of new fat. Research showed women who took HCA (Hydroxycitric acid) lost double the weight compared to placebo. While the placebo group lost 1.4 kg after two months, the garcinia group lost 2.8* kg on average**.

WaterOut EXTREME – quick water-weight relief 

WaterOut XXL contains 8 natural ingredients that combined help against water retention, remove toxins and assist with weight loss; they are CactiNea™ (patented opuntia fruit extract), hibiscus, parsley, watermelon, sarsaparilla, java tea, artichoke and VinOgrape™ Plus. 

CactiNea™ showed remarkable effects when assessed in an open intra-individual (human) study**: there was a 27*% increase in excess water elimination, with the advantage of preserving minerals, and more than 60*% reduction of the swollen legs sensation.

FatBurn XXL – the fat-burning specialist

FatBurn XXL offers triple support thanks to 3 very popular fat-burning ingredients that contain a high enough dosage to achieve results - that means 1000 mg of Carnipure® (the purest L-carnitine on the market), 1000 mg of yerba mate and 700 mg of guarana seed. 

L-carnitine carries long-chain fatty acids (representing the majority of fats we eat) to the cells' furnace mitochondria, where they get processed and burned for energy. 

Guarana and caffeine aid weight loss through 3 main actions: by increasing fat oxidation (the body’s usage of fat for energy), by boosting metabolism by increased energy expenditure and by enhancing the effectiveness of exercise.

AdipoBurn EXTREME – the stomach fat reducer

AdipoBurn XXL targets stomach fat and has a double fat-reducing action: it prevents the enlargement of fat cells (with Morosil®) and it increases fat burning (with MaxiTherm®).

Morosil® is a patented extract obtained only from the juice of the most pigmented blood orange variety Moro from Sicily. They contain anthocyanin, which, in conjunction with vitamin C, carotenoids and folates, was shown to prevent fat accumulation, especially in the abdominal area

A study published in the prestigious paper International Journal of Obesity showed that a 12-week supplementation with Moro juice (blood orange variety) resulted in up to 50%** abdominal fat reduction.
