SlimJOY Capsules
There are so many different diet plans available nowadays, that suggest particular meal choices or avoiding certain foods, and low sugar or low-fat diets are two of these. However, it can be difficult to remove sugar and fat from your diet, so more and more supplements are emerging that aim to help with this, by blocking some of them from being absorbed by the body. SlimJOY Capsules is a weight loss supplement that claims to block 58% of fat and 54% of sugar from everything you eat, as well as stimulating your thyroid with iodine.

In this review, we are going to have a closer look at the SlimJOY Capsules, and see if it is really effective in producing the results it claims.

SlimJOY Capsules Overview

What you need to know about SlimJOY Capsules

The manufacturers claim that there are 8 ingredients in this supplement, however, 2 of those are just fillers so we are not sure why they are saying they are exclusive ingredients. They claim that 1 capsule taken before a meal will block 54% sugars and 58% of fat from a meal, which should lead to a decrease in appetite, although it is unclear where they get these figures from. They also say they offer a 100% satisfaction guarantee.

The individual or even the total ingredient quantities are not listed so it is hard to tell how effective they will be, if at all.

What are the side effects of SlimJOY Capsules?

Potential side effects may include some gastrointestinal symptoms such as bloating, gas, and stomach cramps, as well as increased urination, reduced blood sugar levels, a decrease in blood pressure, and nausea.

How much does SlimJOY Capsules cost?

SlimJOY Capsules are not too expensive compared to other similar products. They cost £15.20 for 60 capsules (a 30-day supply), or £14.99 from Amazon UK.

SlimJOY Capsules Key Features

SlimJOY Capsules is a supplement that is intended to block some of the sugar and fat that you eat from being absorbed by your body, whilst also stimulating your thyroid with iodine.

SlimJOY Capsules Key Points

  • 60 capsules per bottle
  • Manufactured by Sensilab
  • Weight loss supplement intended to block fat and sugar

One of the main ingredients of SlimJOY Capsules is Cinnamon Bark Extract, which is thought to help regulate blood sugar levels by preventing fluctuations in blood sugar levels.

By preventing blood sugar spikes, cinnamon bark is supposed to improve energy. For instance:

Cinnamon can inhibit numerous digestive enzymes, such as alpha-glucosidase (Source), sucrase (Source), and potentially pancreatic amylase (although the only results were confounded with acarbose)(Source). Via inhibition of these enzymes, cinnamon can decrease the influx of glucose into the systemic circulation and avoid overly significant insulin spikes.

However, Cinnamon Bark extract can lead to hypoglycemia and other issues. As well as that, this ingredient has only been found to work when taken in larger doses up to 6g a day, and we have no information about how much of it is included in each serving of this supplement, so it would be wise to avoid it.

How to Take SlimJOY Capsules

  • The recommended dose is 1 capsule with 2 dl of water twice a day before meals

The product also contains a branded ingredient called ID-alG, a seaweed extract believed to affect digestive enzymes and reduce appetite, but this is lacking in evidence to support its use as a weight loss aid. It also contains red vine leaf extract (or Vitis vinifera L folium), and a few vitamins and minerals.

If you struggle with reducing your sugar or fat intake and want to lose weight, then this product might appeal to you. It could potentially offer some support if taken occasionally, for example before a large, heavy meal, but we would not advise someone to take it all the time. It could lull you into a false sense of security and actually encourage you to eat more, expecting this supplement to take it all away. Although ID-alG may have a slight carb and fat blocking effect, it will not block everything and so you may actually find you start putting on weight rather than losing it, with this supplement. That is even if there is enough of this ingredient in the product to have any effect at all, which we do not know.

SlimJOY Capsules Concerns

  • Will the money-back guarantee be fulfilled?
  • Will this supplement encourage you to overeat in the belief it will not add to weight?
  • Limited clinical evidence to prove the active ingredients actually work
  • Where exactly is the company behind the product based?

SlimJOY Capsules are sold by a company called Sensilab who appear to be based in Luxemburg, although returns are sent to Slovenia, and they only deliver to the UK – which is all rather confusing and not very reassuring!

They make lots of other weight loss supplements in both capsule and drink forms, as well as Booty Gels for weight loss and to reduce cellulite. They say their products contain scientifically validated natural substances of the highest quality, designed to nurture our bodies and spirits.

Sensilab can be contacted at Sensilab d.o.o, Verovškova 55a, 1000 Ljubljana, member of Sensilab S.A. Luxembourg – or by e-mail: [email protected]

What does SlimJOY Capsules claim to do?

SlimJOY Capsules claims to block 58% of fat and 54% of sugar from everything you eat by stopping them from being absorbed by the body, as well as also stimulate your thyroid with iodine. They say that sweets and hamburgers will no longer stick to your hips, buttocks and belly!

They then say that by reducing overall sugar and fat absorption you will have steadier blood sugar levels, so you will notice a decrease in appetite.

Does SlimJOY Capsules work?

We think it is unlikely that SlimJOY Capsules will work exactly as described. It is possible that it could help to block some sugar and fat, however there is a lack of any real proof currently to support its use for weight loss, and most of their claims have been based on animal experimentation rather than solid clinical evidence.

Also, the ingredient quantities are likely to be low as they are not disclosed. Cinnamon in particular needs to be in doses as high as 6g to have the required benefits of regulating blood sugar, which it isn’t here.

Added to that, even if this supplement does work, it doesn’t mean it will work for everyone. Unless you already struggle with over-eating fatty foods, you are unlikely to notice much difference. This supplement will not work as a fat burner or help you lose weight.

SlimJOY Capsules Ingredients

The ingredients of SlimJOY Capsules are listed below. There are no quantities provided for each of the ingredients, so it is impossible to say how effective they will be.

  • Cinnamon bark extract: Cinnamon Bark helps regulate blood sugar levels. It is supposed to prevent fluctuations in blood sugar levels. However, it can lead to hypoglycemia and other issues.
  • ID-alG [brown seaweed and grape seeds extracts with 100 – 330 ppm iodine] (content of sulphites >10 mg/kg): ID-alG is a branded seaweed supplement made by Nexira a French company based in Rouen. Brown seaweed contains marine polyphenols that according to research inhibit alpha-amylase (in much the same way as kidney bean extract). Seaweed is also a source of iodine so may have an effect upon your thyroid hormones, which require this vital mineral. Although this sounds good, it is too early to say whether ID alG is effective. Much of the research has been carried out on rats and although Nexira cites a human clinical trial carried out in 2010 in which women lost weight, there is no record of this elsewhere which is odd. Source
  • Red Vine Leaf Extract with 30% total polyphenols (content of sulphites >10 mg/kg): The leaves from a Grapevine. Studies suggest that Grape skin extract may affect blood sugar levels. Red vine leaf contains various nutrients and is used for leg wellness and to improve symptoms associated with venous insufficiency.
  • Zinc gluconate: An essential mineral involved in regulating many enzymes. It is an antioxidant and immune-boosting supplement and can also help improve mood.
  • Nicotinamide: Vitamin B3. When taken at high levels it can lower cholesterol levels and promote heart health. Niacin is present in many foods including green veg and eggs. It can cause stomach upsets, flushing and facial redness if you have too much of it. Source
  • Chromium Picolinate: This trace mineral can be dangerous in high quantities, but is believed to play a role in the reduction of blood fats such as cholesterol and triglycerides. It may improve the way the body uses insulin.
  • Other Ingredients: Anti-caking agent: Rice Concentrate, Capsules: Hydroxypropyl Methylcellulose.

SlimJOY Capsules Side Effects

Although cinnamon bark is usually considered safe, some people may develop some gastrointestinal problems such as:

  • Stomach cramps
  • Gas/flatulence
  • Bloating
  • Diarrhoea
  • Nausea

It can also lead to hypoglycemia and other issues.

Caution: If you are sensitive or allergic to any of the ingredients of the product or take any medicines you should consult your doctor before using it. This product is not recommended during pregnancy or lactation. Do not exceed the recommended daily dose.

SlimJOY Capsules Customer Feedback

We have not been able to find any reviews for SlimJOY Capsules, independent or otherwise, despite the fact is for sale on Amazon.

SlimJOY Capsules Money-Back Guarantee

The company do claim to offer a money-back guarantee, however the terms and conditions state that although a money-back guarantee is only offered for claims within 30 days of purchase, you must ‘follow the course’ before claiming that you are not satisfied. So they seem to be saying that you must take a whole bottle, which will last 30 days and then request your money back, even though you will then be out time to try and get the money-back guarantee!

Added to this, they also say that they have to agree to it in writing after you have submitted a reason for them to investigate. So, unfortunately, we think it is rather unlikely that the money-back guarantee will be fulfilled.

Where To Buy SlimJOY Capsules

SlimJOY Capsules can be purchased from the official website as well as Amazon UK.

Watchdog Verdict

SlimJOY Capsules contains a number of ingredients that are unlikely to help much with weight loss, as there is not enough clinical evidence to back up their use as weight loss aids.

Added none of the ingredient quantities are given at all, which we do not like as we cannot tell the likelihood that any of them will work to have the desired effects. It makes it impossible to say whether this supplement will work and help a consumer lose weight. However, it is likely that the ingredients are in low doses because otherwise, the brand would be likely to share them.

Added to this, a consumer will only take 2 doses a day of this supplement so it not taken with every meal, which is not ideal as any effects won’t be continuous.

The company say that they offer a 100% guarantee if you are not satisfied with the product. However, the terms and conditions state that although a money-back guarantee is only offered within 30 days of purchase, you must ‘follow the course’ before claiming that you are not satisfied. So, are they saying that you must take a whole bottle, which will last 30 days even though you will then be out time to try and get the money-back guarantee?

Added to this, they also say that they have to agree to it in writing after you have submitted a reason for them to investigate! This all concerns us rather a lot.

“Ordered Products may be returned by the Buyer in respect of defective/unsatisfactory product or packaging and the order bill only after Sensilab agrees in writing. The Buyer is obligated to use the products as per the instructions provided and strictly follow the course before claiming dissatisfaction with the said products.”

“..the Buyer shall submit a reason of the alleged defective products to Sensilab for investigation.”

Due to all of these reasons, we simply do not recommend SlimJOY Capsules to our readers.
