SlimJOY NightBurn XXL

Below we take an in-depth look into SlimJOY NightBurn XXL, to see whether this interesting combination of a herbal sleep aid and weight loss supplement can help to tackle this frustrating issue.

SlimJOY NightBurn XXL Overview

What you need to know about SlimJOY NightBurn XXL

SlimJOY NightBurn XXL is a supplement that claims to act as a fat burner, digestive aid, and herbal sleep tonic. Customers are given small sachets of powder that are designed to be mixed with water to make a lime-flavoured drink. If the product is then consumed directly before bed, it supposedly relaxes the body and quietly burns fat overnight.

What are the side effects of SlimJOY NightBurn XXL?

SlimJOY NightBurn XXL is unlikely to cause side effects, although some customers may experience mild nausea, drowsiness, dizziness, and headaches.

How much does SlimJOY NightBurn XXL cost?

As each pack only contains 10 sachets, SlimJOY NightBurn XXL is shockingly expensive. A 10-sachet pack costs £20 from most outlets (plus £6 in shipping costs on the official SlimJOY website).

We did spot the same pack on sale for £16.25 from Vitalobo UK, although this is still pricey for a 10-day supply.

SlimJOY NightBurn XXL Key Features

SlimJOY NightBurn XXL is a lime-flavoured drink that is designed to be consumed shortly before sleep. The manufacturers claim that it can help customers lose weight through fat burning and suppressing the appetite, as well as deliver a more restful and satisfying sleep. It is also stated that deeper sleep has the effect of burning more fat, making the “night-time” action of this product more efficient than other similar weight loss drinks.

NightBurn XXL is produced and sold by SlimJOY, a brand operated by a larger company called Sensilab. The Sensilab group traces its origins back to a research and production facility in Poland, although the modern-day incarnation of the company is based in Slovenia. The company now operates multiple brands and maintains a presence in 35 countries. If customers need to contact the company with queries related to this product, it’s best to contact your local SlimJOY team.

What does SlimJOY NightBurn XXL claim to do?

SlimJOY NightBurn XXL is designed to work as a weight loss and sleep aid, to be consumed directly before bedtime. The manufacturers claim that it has a distinctive “quadruple effect”:

• It improves sleep quality (which is said by the manufacturers to also intensify fat burning)
• It suppresses the appetite for late-night snacking
• It speeds up the process of digestion, which “ensures a flat tummy”
• It helps to reduce fatty deposits in the liver so that the liver can regenerate and have “a good night’s rest”.

The manufacturer also claims that the expected weight loss results will be dramatic; the combination of fat burners and sleep aids will supposedly help customers lose weight “three times faster” than they ordinarily would.

Does SlimJOY NightBurn XXL work?

There is not much reason to suppose that this product would work as advertised. The bulk of the ingredients found in the powder are actually geared towards relaxation, inducing sleepiness, and improving mood/focus. On this count, the drink may work to deliver a restful night’s sleep, although it must be added that there are far more effective herbal sleep aids out there that cannot be found in SlimJOY NightBurn XXL.

The weight loss mechanism is almost laughably absent. The manufacturers appear to be relying almost entirely on garcinia cambogia to act as the magic bullet to burn fat, regenerate the liver, and induce weight loss. The problem is that garcinia cambogia is regarded as a poor and unreliable fat burner, and it is unlikely to deliver dramatic results on its own.

The use of inulin and corn dextrin may suppress the appetite, although it must be mentioned that it seems strange to advise customers to suppress their own appetite directly before sleeping.

SlimJOY NightBurn XXL Ingredients

The ingredients found in SlimJOY NightBurn XXL are listed below. The quantities listed are correct for 1 sachet of powder.

• Chicory Inulin with 86% soluble dietary fibres 3000mg: Some preliminary studies have shown that fructooligosaccharides (or FOS, a carbohydrate found within inulin) aid weight loss by increasing the perception of fullness following consumption. Studies have focused upon FOS sourced from Yacon Syrup, and the amount of weight that participants lost was undisclosed by the researchers. Another study supplementing this product was found to cause a small amount of weight loss over a 12-week period. As a prebiotic, inulin may also support a healthy immune system and relieve digestive problems. Source
• Corn Dextrin with 82-88% soluble dietary fibres 2000mg: This dextrin is produced when cornstarch is subjected to heat. It is indigestible, meaning that it could theoretically function as an appetite suppressant or as a prebiotic that could improve gut health, but there is no strong evidence available to confirm that it has any positive effect on humans. Source
• Calcium L-Pidolate (calcium) 200mg (25% NRV): Studies have shown that calcium can play a significant role in weight loss, especially loss of fat mass. Research shows that fresh dairy sources of calcium are more effective than supplementation. The amounts that are included in this product may only make a minimal difference to dieting attempts, as studies in humans showed weight loss results when consuming 600mg of calcium in addition to that found naturally in their calorie restricted diet. Source
• Tri-Magnesium Dicitrate, anhydrous (magnesium) 187.5mg (50% NRV): Magnesium is one of the electrolytes that our body needs to function properly, although it is often expelled from the body through urine and sweating. Magnesium is used for over 600 functions in the body, and so it is certainly important to get enough, ideally through diet. Some studies suggest that magnesium supplementation could enhance exercise performance and mental performance. Source
• Garcinia Cambogia extract with 60% hydroxycitric acid 800mg: Test tube and animal research suggest that HCA, the active compound in Garcinia Cambogia, may be helpful in weight loss because of its effects on metabolism. However, numerous studies in humans have found it has no effect upon either appetite or metabolic rate. Source
• Choline Bitartrate 400mg: Choline supplementation appears to improve attention, and could improve memory, although the relevant study focused upon the elderly only. Choline is required to make increased levels of acetylcholine in the brain, which is a neurotransmitter that is linked to improved learning, memory retention, and recall. Athletes sometimes supplement various forms of Choline to delay fatigue and improve endurance, but there is little evidence to support this. Source
• Elderberry Fruit extract 280mg (with 50% vitamin C – 140 mg (175% NRV)): This ingredient is a source of antioxidants, specifically flavonoids which could benefit the body’s immune system. This perhaps explains why they were used in folk medicine to treat colds and flu. Source
• Lemon Balm leaf extract with 15% hydroxycinnamic acid and 7% rosmarinic acid 200mg: The chemicals in lemon balm appear to have a calming effect when consumed. Supplementation of lemon balm could act as a treatment for anxiety, stress, agitation in Alzheimer’s patients, and sleep problems. Source
• Chamomile Flower extract 100 mg: This herb may aid relaxation and sleep. It has also been used as an effective heartburn and diarrhoea cure. Source
• Vitamin B6 5.6mg (400% NRV): Vitamin B6 has several important functions in the body, including ‘allowing the body to use and store energy from protein and carbohydrates in food’. Whilst taking excess amounts of vitamin B6 will not infinitely improve this ability, a deficiency could make it more difficult to lose weight. Source
• Natural Lime flavour
• Lemon Fruit concentrate powder
• Acidity Regulator: Citric Acid
• Anti-Caking Agent
• Rice Concentrate
• Sweetener: Sucralose

SlimJOY NightBurn XXL Side Effects

A few of the ingredients found in this product could cause side effects, although the overall risk of experiencing side effects should be regarded as low.

Garcinia Cambogia can cause some side effects including nausea, digestive tract discomfort, and headache. Chamomile can cause drowsiness and in large doses can cause vomiting.

Lemon balm can very occasionally cause issues, including nausea, vomiting, dizziness, and wheezing.

One final concern is that the formula uses a needlessly high dose of Vitamin B6 – although this ingredient is not thought to be harmful in normal circumstances, such a large quantity can cause flushing, brain and nerve problems, vomiting, loss of appetite, headaches, tingling, and sleepiness.

Watchdog Verdict

Although the concept behind SlimJOY NightBurn XXL is interesting in theory, there really is no reason to think that this formulation works at all.

Although the ingredients list contains one or two herbal ingredients that could aid digestion or relaxation, the manufacturers rely entirely on garcinia cambogia for that crucial fat-burning mechanism. The problem? Garcinia cambogia has been repeatedly proven to be one of the world’s least impressive and most unreliable fat burners. It simply can’t be relied upon to deliver impressive results on its own, so it remains highly likely that this product does not work in the advertised way.

This is a hard pill to swallow when you remember that this product has to rank as one of the most expensive of its kind. When factoring in delivery costs, each sachet/serving of NightBurn XXL costs an eye-watering £2.60.

Customer reviews indicate that SlimJOY often fails to deliver packages on time and tend to make shipping errors, which could compound the misery from all angles.

Overall, we would suggest sticking with the individual fat burners and sleep aids that work for you, and stay well away from this poor-quality hybrid effort.

We do not recommend SlimJOY NightBurn XXL to our readers.
