SlimJOY BootBurn Intensive

Published Oct 22, 2018.

SlimJOY BootBurn Intensive is a peach-flavoured powder that you add to water to burn fat. There are actually several claims attached to this product, but there doesn’t seem to be much evidence that it works (despite the manufacturers saying it is clinically proven). It seems cheap enough at first glance, although if taken as directed each box will only last for 15 days. We couldn’t seem to locate any customer reviews online, so either nobody is trying it, or the reviews are being deleted.

SlimJOY BootBurn Intensive Concerns:

  • Claim their products are clinically proven

What does SlimJOY BootBurn Intensive claim to do?

Sensilab/Slim JOY claim that their Boot Burn intensive supplement is clinically proven and does the following:

  • Burns 5.7% more fat during periods of rest
  • Stimulates the use of stored fat as the first source of energy
  • Improves the weight ratio between muscles and fat
  • Reduces the absorption of sugars
  • Increases vitality

Does SlimJOY BootBurn Intensive work?

There’s a lot of caffeine in the SlimJOY Boot Burn Intensive. Caffeine does help to increase metabolism and burn fat, so to a mild extent, this product will work for some people.

Saying that, kola nut extract has only been shown to work when combined with ephedra and willow, and ephedra is now a banned substance in the USA because of its dangerous side effects, and at the moment, there is no evidence that, other than the caffeine content, this ingredient works as a stand-alone. Ginger is a good ingredient to aid digestion and ease symptoms such as wind and bloating, but there is no evidence to show that it works as a weight loss ingredient.

We don’t generally think that this product will work for most people, certainly not in the way that SlimJOY/Sensilab claim that it will.

SlimJOY BootBurn Intensive Ingredients

These quantities are correct per 3g serving of the supplement:

  • Kola Extract (from caffeine 10%) (800 mg): This is an ingredient containing caffeine. Early studies have shown that when taken in combination with ephedra and willow for up to six months, they may help with weight loss. However, ephedra has been banned in the USA due to its significant and often dangerous side effects. There is nothing to show how effective this is as a stand-alone ingredient.
  • Green Coffee Bean Extract (svetol) (from chlorogenic acid 45% caffeine 2%) (400 mg): Green Coffee Bean Extract is actually the raw coffee beans that are contained inside the red berry. Usually, coffee beans are roasted to provide the characteristic aroma and taste loved by coffee connoisseurs. In this case however, the seeds are left unroasted and are then soaked and concentrated in order to prepare the extract. This keeps the chlorogenic acid, the main ingredient for accelerating weight loss, intact within the beans. Caffeine which is considered to be the one of most powerful antioxidant and stimulant is also found in large amounts within unroasted coffee. This is quite a decent serving.
  • Ginger root (from gingerols 5%) (50 mg): Ginger root is an ingredient well known for having a positive effect on digestive health, in that it is often taken to ease nausea and sickness, and various types of digestive issues such as trapped wind.
  • B3 (niacin) (30 mg): This vitamin is normally only useful in cases of deficiency, although very high doses are known to help lower cholesterol (higher than the dose used in this product). Source

SlimJOY BootBurn Intensive Side Effects

Thanks to the kola nut and green coffee bean extract, there is quite a significant amount of caffeine in SlimJOY Boot Burn. This can cause side effects such as insomnia, disruption to sleep, increased heart rate, raised blood pressure, heart palpitations, jitteriness, anxiety, and increased urination. Kola nut should not be consumed by anyone with an allergy to nuts. It can also affect people with high blood pressure or cardiac issues. It can also cause nausea.

Watchdog Verdict

We were intrigued by the promise of ‘clinically proven’. There are not many supplements out there that make such a bold claim. Maybe this was going to be a weight loss and fat burning supplement that actually worked?

Or, maybe, the manufacturers have found a few studies backing up some of the ingredients and used this as their basis for ‘clinically proven’. Yes. That is exactly what has happened here.

We know that caffeine is pretty good for fat burning – we have seen plenty of studies to support it. This supplement does have a pretty good dosage as well. But, does that mean it will absolutely work? Nope! Something we found very strange as well is that two of the three studies that they have linked to as a base for their research refers to green tea leaf extract – this supplement, as far as we can see, does not contain any green tea leaf extract. If someone is going to make big claims, they need to make sure they are substantiated.

We have been unable to find any independent reviews for this supplement online, which always makes us wary of a product. We like to know what people think before we spend our hard earned money, especially if only unopened, sealed products can be returned – and they have to be returned to Slovenia. This can be costly for someone living in the UK, and they do not get any of the shipping costs refunded.

Another thing that puzzles us, is their warning about keeping the product out of reach for children under the age of three. Surely, they should be kept out off the reach of children whatever their age. We are assuming this is a communication or language barrier error and we would also hope that most customers would be vigilant. However, this is a pretty basic and serious error (if it is an error!) to make.

Because of these factors, we do not recommend the SlimJOY Boot Burn Intensive to our readers.
