Supercharge your night-time weight loss

Now in three yummy flavours! 

Lemon, lime, pineapple

4-in-1 effect on night-time fat burning

No stimulants to disturb your sleep.

The longer and better we sleep, the more fat we burn!

Boost fat burning

Burn fat while you sleep to accelerate weight loss and make the most of your night-time rest. 

Prevent fat accumulation 

Nip new fat formation in the bud and prevent fat from sticking to your hips and thighs. 

Prevent evening hunger 

Don’t let hunger get the best of you. Evening fridge raids can reduce your sleep quality and make your slimming process slow and difficult. 

Relax and improve sleep 

Let NightBurn alleviate tenseness, restlessness and irritability, and help you relax and sleep better.

Resetting your biological clock is the key to effective weight loss!

It will help you fall asleep more quickly and sleep better. You’re more likely to go for low-calorie snacks and burn fat much faster if you're fully-rested.

With the power of Garcinia Cambogia, you're good and ready to beat evening hunger pangs and urges to raid the fridge. 

The liver is the ultimate fat-burning machine. If overwhelmed, it can result in a minimised fat-burning rate. It helps to keep your liver in good shape to ensure the best possible results.

With an outstanding combination of water-soluble fibre, Garcinia Cambogia extract and vitamin B6, it prevents the storing of fats and stimulates the fat-burning process.

Unlike similar products, it contains no hormones or hormone precursors. Its natural extracts improve your sleep in a natural way.

You'll be able to fall asleep faster and keep your daytime weight-loss mission right on track. 

Lets you sleep like a baby and wake up refreshed!

Caffeine-free, high in fibre and easy to prepare.

Drop pounds while you sleep!

Many studies have shown a link between sleep and weight loss. During sleep, our bodies draw on fat stores. The longer & better we sleep, the more fat we burn. 

NightBurn XXL accelerates your night-time fat-loss both by 

  • improving your sleep

  • supercharging your fat-burning

Most weight-loss supplements contain stimulants, such as caffeine, which is why you can’t take them in the evening or late at night. With NightBurn, it’s just the opposite!

Thanks to a synergistic mix of carefully selected ingredients, it helps you relax and prepare for a restful sleep. It doesn’t get better than that!

Top night-time fat burner on the market

Studies have shown – the longer and better we sleep, the more fat we burn.

Star ingredient: Garcinia Cambogia 

Scientific studies** prove that Garcinia Cambogia can speed up weight loss and help you reach your weight-loss goal faster! It mainly works by:

  • boosting fat burning,

  • preventing fat accumulation, and 

  • curbing evening cravings

Women who took HCA (hydroxycitric acid), the main active ingredient from Garcinia Cambogia, lost double the weight compared to placebo.

While the placebo lost 1.4 kg* after 2 months, the Garcinia Cambogia group lost 2.8 kg* on average.
