  • Contains glucomannan, which has been proven to suppress the appetite effectively

Juice Plus Booster
Glucomannan is one of the few genuinely exciting ingredients around in the world of supplements, as it is one of the only weight loss ingredients that can actually deliver results. This dietary fibre is known to rapidly expand in the digestive system, helping customers to feel artificially full and effectively suppressing the appetite.

Although this promising ingredient often comes in pill/capsule form, some manufacturers have begun experimenting with other delivery systems, such as powders.

Juice Plus Booster Overview

What you need to know about Juice Plus Booster

Juice Plus+ Booster is a weight loss supplement that is intended to be consumed before meals. Although it uses a well-known appetite suppressant (glucomannan), it is actually advertised as a simple weight loss product, with the manufacturer seemingly taking care not to make any strong statements on what the product does.

The manufacturer of Booster, Juice Plus+, is an incredibly controversial manufacturer that has been repeatedly accused of false advertising and dishonesty. Their incredibly expensive products are mainly sold by independent distributors, many of whom have been tricked into buying large amounts of expensive, useless stock that they will be unable to sell. The company has made huge efforts to falsify scientific studies that “prove” their products work, and prices their products in a very confusing way to trick customers into handing over more cash than they intend. To top it all, most of their products are thought to be broadly useless!

What are the side effects of Juice Plus Booster?

Glucomannan absorbs a lot of water and expands in the stomach. It can also expand significantly when it meets water outside the body. This product uses a powdered form of glucomannan that customers are instructed to mix with water, which could pose a serious choking hazard (Juice Plus+ even warn about this on the label).

Customers need to drink lots of water when taking this product, in order to help the glucomannan move properly in the digestive system. If dieters fail to do this, glucomannan can cause constipation, diarrhoea, and stomach cramps. The small caffeine content may also cause mild jitters, sleeplessness, irritability, or a raised heart rate.

How much does Juice Plus Booster cost?

Juice Plus+ Booster is an incredibly expensive supplement! Customers looking to buy Booster online should realise that Juice Plus+ are misleading or outright dishonest when pricing their products online, and extreme caution should be exercised. You may be taken unawares and be charged a huge amount of money for nothing!

On the official Juice Plus+ website, one 30-serving box of Booster costs £76, which can be split into 4 monthly payments of £20.50. Splitting the cost into 4 payments will not get you 4 boxes (as anyone would expect), it just gets you one very expensive box of 90 sachets.

On Amazon, the company just straight-up lies. Customers can purchase boxes containing a “10-day supply” or a “20-day supply”. However, these boxes only contain 10 sachets and 20 sachets respectively – this is not a 10 and 20-day supply! For £16.95, you actually only receive little over a 3-day supply, and for £33.50 you receive just under a week’s supply. We essentially consider this to be a scam.

When buying from independent distributors, prices may vary considerably depending on who you’re speaking to.

Juice Plus Booster Key Features

Juice Plus+ Booster is a weight loss powder that is intended to be mixed with water and consumed before meals. It is part of the manufacturer’s “Complete” product range, which also includes shakes, soups, and cereal bars.

Juice Plus Booster Key Points

  • Manufactured by Juice Plus+
  • Contains 270g of powder (90 x 3g sachets)
  • Weight loss powder supplement

Booster is manufactured by Juice Plus+, a multi-level marketing company that became famous for selling capsules of fruit, vegetables, and berries. Juice Plus+ has been involved in so many controversies by this point that it’s hard to count them! The company has been accused of falsifying the scientific evidence that supposedly proves their products work, by filling university research teams with their own employees. ConsumerLab has found that Juice Plus+ misrepresents the ingredient quantities in their products, and the Better Business Bureau has accused the company of misleading advertising. Despite a strong reputation for being mostly useless, Juice Plus+ products are some of the most expensive you’ll find, which has resulted in serious financial strife for their army of distributors and customers. The company can be contacted via the details supplied on their official website.

How to Take Juice Plus Booster

The directions for use are as follows:

  • Dilute the contents of a sachet with 1-2 glasses of water, stir and drink. Please note: the solution will remain cloudy even after vigorous stirring. Take before meals, 3 times a day. Note: it is important to drink plenty (1-2 glasses) of water, as advised in these instructions, to ensure the product reaches the stomach. Do not exceed the recommended daily intake.

Juice Plus Booster Concerns

  • Price is extraordinarily high and presented in a way that tricks or outright lies to customers
  • No returns policy or money-back guarantee for this product
  • Virtually all customers comment negatively on the taste

What does Juice Plus Booster claim to do?

Juice Plus+ Booster is mainly intended to act as a weight loss aid. Customers are invited to mix the powder with water, and then consume the mixture before meals. The way that the product actually works is never explained on any product page we could find; the manufacturer simply states that the ingredient glucomannan “assists weight loss as part of a low-calorie diet”.

Does Juice Plus Booster work?

The main active ingredient in Juice Plus+ Booster is glucomannan (the quantities of the other main ingredients are probably a bit too low to make much of an impact). It’s quite odd that Juice Plus+ never bother to explain what glucomannan does or how it works (we presume their history of being accused of false advertising now means that the company shies away from making any claims at all!). Glucomannan generally helps with weight loss by suppressing appetite. It’s generally thought to be very effective at this role, as it expands in the digestive system and makes dieters feel artificially full.

However, Booster absolutely does not work. The problem is the taste; most customer reviews claim to not be able to use the product due to its appalling taste. We have no idea why Juice Plus+ thought it would be a good idea to give customers a dose of glucomannan in powdered form, but the end result is that few customers can tolerate having it in their mouths!

phentatrim bottle
The most popular appetite suppressant in 2021 is Phentatrim.

Its ingredients are scientifically proven to aid weight loss and you are covered by a full 60-day money-back guarantee from a trusted company, making Phentatrim a very popular choice in the diet world.

Phentatrim is the best thing to hit the supplement market in a long time, with thousands of customers already seeing the benefits. That’s why it's our editor's top pick.

Juice Plus Booster Ingredients

The ingredients found in Juice Plus+ Booster are detailed below. The ingredient quantities listed are for 3 sachets of Booster.

  • Glucomannan 3g: This fibre comes from the root of konjac. The powder absorbs water upon contact and becomes gel-like in consistency; it not only helps to fill the stomach but also slows down digestion, meaning that the dieter can go for longer before feeling hungry again. There are numerous studies that show glucomannan use leads to weight loss, without making any other changes. Source
  • Green Tea Extract: Green tea is high in a group of antioxidants called catechins. Studies have suggested that catechins and caffeine both increase energy expenditure, by boosting the metabolism temporarily. However, the metabolic increase caused by green tea is limited. One study found that the use of green tea was not enough to counteract weight gain following a high-calorie diet. Source
  • Caffeine 25mg: Numerous studies have shown that caffeine boosts energy levels and alertness, as well as mildly boosting the metabolism, causing a small increase in the number of calories used by the body. The effects shown in studies are small, and some studies are inconclusive. Source

Juice Plus Booster Side Effects

Glucomannan works by absorbing water and expanding, so drinking a powdered form of it with water can lead to choking (especially as some customers have resorted to holding water in the mouth and then pouring the powder inside to avoid the taste).

Obviously, the process of expanding continues in the stomach, making it very important to drink plenty of water when taking the product, and to adjust the dosage if problems occur. Consumers who do not drink enough water when taking glucomannan may experience constipation and stomach cramps. As glucomannan is a fibre, it is likely that its use will increase the rate of one’s bowel movements. Diarrhoea may also occur. Those who experience diarrhoea should cease using the product immediately. Glucomannan also affects blood sugar levels. Diabetics should consult their doctor before taking any glucomannan-based product.

The quantity of caffeine is not overly high, although at least one customer has complained of side effects. For those who are sensitive to caffeine, a product like this may cause headaches, increased urination, dehydration, jitteriness, increased heart rate, increased blood pressure, heart palpitations, and problems sleeping.

Caution: For people with swallowing difficulties or when ingesting with inadequate fluid intake, there is a risk of choking. Contains caffeine. Not recommended for children or pregnant women. This product is subject to constant laboratory monitoring. Store in a cool, dry place. Keep out of reach of children.

Juice Plus Booster Customer Feedback

Virtually every customer reviews mention the poor taste of Juice Plus+ Booster as a hurdle to overcome, with some expressing success and others seeing no improvement in their weight. Many customers also complain about the outrageous business practices of Juice Plus+ in general, who regularly rip off customers with their deliberately misleading sales terms.

Tastes so awful I have been unable to tell if it works

Didn’t notice any difference

Utter rubbish. I’ve not seen any difference in my weight or energy levels. TOTAL WASTE OF MONEY. The JP didn’t explain that although it’s a 90 day plan you only get 30 days supply but pay it over 4 months. I’m furious. DONT BUY THIS

Hugely disappointed… Advertised as a 10 day trail ! On the packet it states 3 times a day… Equalling 30 packets! Received 10! NOT A 10 DAY TRIAL

These totally work! Once you get over the fact that they taste of crayons then they’re fine. I put mine in squash instead of water to hide the taste but I’ve definitely noticed a difference!

Feel a slight difference. Thank you.

Juice Plus Booster Money-Back Guarantee

Although Juice Plus+ offer a money-back guarantee in North America, the European branch does not even offer a returns policy in any form. As Booster can only be purchased in Europe, this means that customers will not be able to return their product for refund under any circumstances.

Where To Buy Juice Plus Booster

Juice Plus+ Booster is only available to buy in Europe. Customers looking to buy online can find it on sale on the official Juice Plus+ website or on Amazon. Most customers looking to buy Juice Plus+ products may find better deals by purchasing from one of the many Juice Plus+ distributors that sell face-to-face.

Like all Juice Plus+ products, Booster is eye-wateringly expensive. The company also frequently misrepresents the sales terms online to trick customers, so always read everything very, very carefully. Customers can buy one pack of Booster with 30 servings (90 sachets) for £76, which can be split into 4 payments of £20.50 if the customer chooses. Customers can also buy 10 sachets of Booster (a little over a three-day supply) for £16.95 on Amazon, and 20 sachets (a little under a week’s supply) for £33.50 on Amazon. Both deals are advertised as a 10-day supply and a 20-day supply respectively, which is essentially a lie (as the product won’t work unless dosed correctly).

Watchdog Verdict

Juice Plus+ is one of the most disgraceful companies out there, and we strongly advise all readers to avoid them entirely. Whether operating as a distributor or a customer, Juice Plus+ only exists to rip you off, selling disgustingly expensive products that are generally known to be ineffective or useless.

Booster is actually a great example of this. It gives customers a dose of glucomannan in the most baffling way imaginable, instructing customers to mix a powdered form of the root with water. This not only predictably tastes disgusting, but also poses a significant choking hazard that could threaten lives. There’s a reason why supplement manufacturers often use tablets/capsules, and this is a big reason why when it comes to glucomannan!

Booster is not protected by a money-back guarantee, and customers will be charged $76-£150 for a month’s supply depending on where they buy it. Almost any other product would be preferable to this one!

We do not recommend Juice Plus+ Booster to our readers.
