Slendershot Overview

What You Need To Know About Slendershot

Slendershot is an unusual weight loss product that comes in the form of drinkable “shots”. Customers are invited to drink one before eating once a day, and are told to expect a range of benefits, including weight loss, a better mood, and more energy. Slendershot is also described as having a detox effect, although the actual toxins that are supposedly expelled are never specified.

What Are The Side Effects Of Slendershot?

Although there aren’t too many customer reviews for Slendershot online, many of those that we have seen complain of side effects like nausea, bloating, diarrhoea, and more. Some of the ingredients found in this product may also cause sleep problems and headaches.

How Much Does Slendershot Cost?

On the official Slendershot website and on the Holland & Barret webstore, a 28-day pack of Slendershot costs a standard price of £29.99. Customers can find the same pack for slightly cheaper on Amazon, where it costs £25.86.

On the official Slendershot website, a 14-day pack is also available for £19.99, as well as a 3-month pack (with free shaker and detox plan) for £69.95.

Our Verdict On Slendershot

For us, seeing the word “detox” is always a big red flag, because it immediately tells us that the seller isn’t really promising anything other than vaguely defined nonsense. A more detailed look at Slendershot shows it to be nothing more than that.

Like most other junk products, Slendershot packs in a long list of ingredients into a tiny tube, most of which are thought to be ineffective. Although the manufacturer fails to list ingredient quantities, the bits of information we can see suggests that minuscule quantities of each ingredient seem to have been included, rendering the whole mix pretty useless. The selection of ingredients is also strange; to us, the manufacturer appears to have just slapped dozens of random ingredients together with no rhyme or reason.

Slendershot is not a very popular product and has attracted relatively little buzz and very few customer comments online. Those that are available to read tend to be highly mixed, with a surprising number of customers complaining of side effects. Those dissatisfied with their purchase are out of luck, as the manufacturer offers nothing in the way of a money-back guarantee.

The idea of a weight loss “shot” sounds fun, but the execution just results in a silly and ineffective gimmick.

Overall, we do not recommend Slendershot to our readers.

Slendershot Key Features

Slendershot is a weight loss drink that is designed to be taken as a “shot” before eating. The product is sold in the form of small red test tubes, and contain a mixture of water, sweetener, and weight loss herbs and amino acids. All packets of Slendershot are vegan and vegetarian-friendly.

Slendershot Facts

  • Manufactured by Slendershot
  • Contains 14 or 28 sachets per box (depending on pack selected)
  • Weight loss “shots” that are designed to be taken before meals

This product is manufactured by a UK-based company that also appears to be named Slendershot. Slendershot only promotes the product for which they are named, and so far only endeavour to sell it online (although they hope to bring Slendershot into high street stores “soon”). The small company already recruits distributors and has partnered with athletes and TV presenters to sell their flagship product. The company can be contacted by email ([email protected]) or via the contact form provided on their official website.

How to Take Slendershot

The directions for use are as follows:

  • Simply take one shot per day, 30-60 minutes before eating – morning, afternoon or night over 28 days!

Slendershot Concerns:

  • Unlikely to have any appreciable effect on weight or anything else
  • Ingredient quantities not listed
  • Manufacturer fails to offer a money-back guarantee to take the risk out of purchases

What Does Slendershot Claim To Do?

The manufacturers claim that Slendershot helps customers to detox and achieve their weight loss goals. The various ingredients found within the mix are variably said to boost the metabolism, burn fat, and reliably “put a spring in your step”.

The formula is also said to act as a good source of antioxidants, which will reportedly “restore health” and provide a burst of energy. The manufacturers also claim to have added a “mood enhancing” formula that can effectively combat street and boost the immune system.

Does Slendershot Work?

Slendershot packs in a wide variety of seemingly random supplement ingredients in each tiny tube. The various properties expected of the ingredients contained in this product range from having laxative effects, fat binding, suppressing appetite, inducing relaxation, and more.

However, having dozens of ingredients is rarely a good thing. The manufacturers fail to disclose ingredient quantities, but a trained eye can see that the quantitative extraction ratios and percentages that are quoted are laughable, telling us that the dosages are likely to be pathetically small. In essence, Slendershot appears to be little more than water with specks of various useful ingredients sprinkled in as an afterthought. We wouldn’t expect this product to have any effect.

What Are The Ingredients of Slendershot?

The ingredients found in Slendershot are listed below. Unfortunately, the manufacturer fails to list proper ingredient quantities, which makes it impossible for customers to estimate how effective the overall mix is.

  • Water
  • Sweetener
  • Glycerine
  • Natural Blackcurrant Flavour
  • Natural Raspberry Flavour
  • Vitamin C
  • Xanthan Gum
  • Preservative Potassium Sorbate
  • Preservative Sodium Benzoate
  • Natural Granny Apple Flavour
  • Colour Magenta
  • Colour Red Anthocyanin
  • Acerola Extract 12:1 17%: This fruit is known for its high Vitamin C content but has no real properties as a supplement. Source
  • Aloe Vera Leaf Extract 200:1 0.30%: Aloe Vera has been used to treat constipation when taken orally, as it appears to have a laxative effect. Source
  • Siberian Ginseng Rhizome Extract 25:1: Unfortunately, the clinical trials that suggest that Siberian Ginseng has clear medicinal benefits are either low-quality studies in humans, or are from testing in vitro or in animals. Some studies suggest that the plant can help to reduce cognitive decline and boost cognition in general, but the clinical support is far from conclusive, or well tested in human subjects. Source
  • L-Arginine Hydrochloride 0.12%: Arginine is an essential amino acid which is plentiful in foods and can be made by the body. Important for wound healing and circulation, l-arginine is thought to boost the levels of Nitric Oxide in the body (which effectively supplies more blood to the muscles). Source
  • L-Glutamine 0.10%: This essential amino acid is a building block of protein (muscle). Source
  • 5-Hydroxytryptophan (5HTP) 0.10%: 5HTP is used by the body to make serotonin, which primarily plays a role in regulating mood. Some studies, primarily in animals, have shown that 5HTP reduces the appetite, as well as boosting mood.
  • Prickly Pear Powder: The Prickly Pear Cactus is known to significantly reduce blood sugar levels after consumption when prepared correctly. The edible pulp of the cactus can also reduce LDL cholesterol levels. One preliminary study found that cactus consumption increases the amount of fat found in stools, suggesting that the fruit binds with some fat in the stomach, partially preventing digestion of this fat. Long-term use of prickly pear has not been studied. Source
  • Beta Alanine: Beta alanine has been repeatedly proven to raise the levels of muscle carnosine in the human body, which has the effect of increasing the amount of work athletes can perform in high-intensity workouts. Its use is accompanied by a distinctive “tingling” sensation in the muscles. Source
  • Liquorice Root Extract 5:1: Liquorice can be used to treat digestive problems, but can cause water retention. Source
  • Calcium Pyruvate: This ingredient is thought to increase the breakdown of fat. Source
  • Acai Berry Powder: A berry that has been wrongly hyped up as a weight-loss super-food, the use of acai berry in diet pills has rocketed in recent years. Acai berry is high in Anthocyanins, antioxidants which may help to protect the body against cancer, inflammation, aging, neurological diseases, diabetes, and bacterial infections. However, any claims that it aids weight loss are unproven. Source
  • Capsicum: Capsaicin, which is found in Cayenne pepper, is thought by some to play a role in weight loss. Some studies suggest it could suppress the appetite mildly, whilst others suggest that the heat causes a thermogenic reaction in the body, burning more calories for a period of time. However, there are also studies that show cayenne has little or no effect upon weight loss attempts. Source
  • Green Tea Leaf 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. Source
  • Grapeseed Extract 120:1: Grape seed extract may help to lower cholesterol levels and improve poor circulation. It is also high in anti-oxidants, which may benefit health in general. Source
  • Spirulina 0.0042%: Spirulina is a blue-green algae that contains a range of natural vitamins and minerals. Almost all claims made about it are currently unsubstantiated, although it is thought to synthesise/release Nitric Oxide. Source
  • Ginger Root Powder: Some studies suggest that ginger root is an appetite suppressant. One study used dried ginger powder to make a tea that participants drank with breakfast. Researchers found that satiety levels were much higher when the tea was consumed with breakfast, rather than just the breakfast on its own. Source
  • Guarana Seed Extract 4:1 0.0042%: This berry is naturally high in caffeine, and it is often an ingredient used in energy drinks and diet pills. Source
  • Garcinia Cambogia Fruit 0.0042%: Test tube and animal research suggest that HCA, an 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

Does Slendershot Have Any Side Effects?

Although the majority of the ingredients seem to be under-dosed, this product may still cause side effects (which some customers have complained of).

Some of the natural ingredients found in this product (such as garcinia cambogia, acerola extract, and prickly pear) can cause mild side effects such as diarrhoea, stomach cramps, sleep problems, headaches, and bloating. Laxatives like aloe vera may also cause more frequent bathroom visits.

Potential side effects of Siberian Ginseng include drowsiness, changes in heart rhythm, sadness, anxiety, muscle spasms, and, when used in high doses, and increased blood pressure.

Not suitable for pregnant or breastfeeding women. Not suitable for anyone under the age of 18. If you are taking any medications or are unsure about the suitability of this supplement for you, consult your doctor before purchase.

Are There Any Customer Reviews For Slendershot?

We weren’t able to find too many customer reviews discussing Slendershot online, although the few we did spot were decidedly mixed. A surprising number of customers complained of side effects.

Only took 4 of these from a 14 day trial, and had to stop them, gave me a very upset tummy and bloated tummy, also had diarrhoea… felt better after I stopped them, having said that they may work for other’s but not me

I put on more weight!

I quite liked these and didn’t have any adverse effects. I definitely ate less whilst taking these and slimmed down a little. I would guess maybe a 3 or 4lbs in a month, but can’t say for sure as I didn’t weigh myself.

Does Slendershot Offer a Money-Back Guarantee?

On their official website, Slendershot explicitly states that they do not offer a money-back guarantee. Customers may be able to return unwanted products as long as they are in a re-saleable state, but the company won’t accept returns simply because customers are dissatisfied.

Where Can I Buy Slendershot?

Slendershot is available to buy on the manufacturer’s website, Amazon, and Holland & Barrett. Although all prices are quoted in pound sterling, the manufacturer can also arrange for international shipping if desired.
