Therma-Rip Review

Therma-Rip Facts

  • Therma Rip is marketed by Monkey Nutrition based in Cheshire UK
  • Each bottle contains 90 capsules
  • Contains listed 20 ingredients

Therma Rip is a diet pill on sale from British company Monkey Nutrition.

It looks strong at first glance and this impression is reinforced by the ingredients list. Therma Rip contains 20 ingredients many of which show up regularly in other supplements although that said, we have never seen this precise combination before.

There are ingredients to promote the fat burning effect such as Green tea and Guarana, a powerful stimulant. Other ingredients such as Chitosan are believed to decrease appetite and bind fat and there are diuretics to make you urinate more such as Uva Ursi.

In addition Iodine from kelp is included because of its effect upon the thyroid. This is not forgetting the ingredients to decrease oestrogen – really! And of course, those ingredients that have a so-called effect upon boosting your adrenaline levels.

It is as if the makers couldn’t decide quite what ingredients to put in one diet pill so settled on all of them in as a simple solution.

Will this approach work? It might, but beware there may be side effects and we cannot tell whether this precise combination has ever been tested or whether all these ingredients are suitable for use in combination. In addition, is it good for health to mess with your hormones and adrenaline and increase the amount that you urinate? We don’t believe that it is and can see no real benefit.

It is not clear where Therma Rip is manufactured and this is slightly worrying. According to the product information, all Monkey Nutrition supplements are manufactured in an “FDA approved and fully inspected facility” but the location or country of origin is not disclosed and it could be just one of those meaningless phrases that sound good. There is no proof or evidence.

The FDA reference sounds as if it should be in the USA but in truth the FDA never approve facilities or manufacturing premises. They do inspect product manufacturers to verify that they comply with good manufacturing practices.


Monkey Nutrition looks to be an extremely slick operation. The website is attractive, glossy and good quality and has a more US friendly style than many other British supplement companies manage to achieve. According to the company information;

Monkey Nutrition is a new kind of beast in a supplement world that too often markets poor quality products full of empty promises

How to Take Therma-Rip

Take 1 tablet with 250ml of water 30-45 minutes before breakfast and lunch.

This product should be used in conjunction with a sensible diet and exercise program.

Do not exceed two tablets daily.

Monkey Nutrition carry wide product range, all related to sports nutrition, weight loss and body building. These include protein powders and the Primal range of protein powders seem especially popular. Monkey also sells a range of Paleo foods and bundles of various products to target specific issues such as Men’s Health for example. All supplements come in distinctive black packaging featuring what looks like an angry cartoon monkey logo.

Therma-Rip Concerns:

  • Where is this supplement manufactured? The information does not provide the country of origin
  • This formula has never been tested-There may be ingredient interactions
  • Probably will not work in the way as described and a strong risk of side effects

What Does Therma-Rip Claim To Do?

According to the advertising Therma Rip is an “Extreme fat burning complex, (that) regulates thyroid metabolism and supports lean muscle tissue.”

It “combines thermogenics, metabolic and adrenal stimulants, appetite suppressants, diuretics, glucose disposal agents, anti-estrogens and thyroid regulators, as well as immunity enhancing ingredients.”

The advertising states,

The combination of these ingredients is vital to fat loss and can initiate chemical reactions that cause fat cells to release their energy and simply melt away!

There is no evidence that any of this really true and no links to clinical evidence. We doubt that this formula has ever been tested.

So What Is Therma-Rip and What Are The Ingredients For Therma-Rip?

Therma Rip looks to be a multi purpose diet pill that the makers claim will help you lose weight via a number of ways. Each capsule is equal to one serving.

  • Vitamin B-6 (as pyridoxine hydrochloride) (25 mg): This form of vitamin B6 supplement is often used in supplements. Vitamin B6 is involved in many aspects of the metabolism and vital for the breakdown of lipids.
  • Iodine (from kelp) (150 mcg): Trace element that helps make the thyroid hormones –which in turn control metabolism. Iodine is present in fish and seafood so sometimes lacking in diet. Taking iodine supplements can be dangerous but the NHS advise that taking 0.5mg or less a day of iodine supplements is unlikely to cause any harm.
  • Chromium (amino acid chelate) (100 mcg): This trace mineral is believed to promote muscle growth and fat burning but lacks evidence. Chromium is present in a normal diet and scientists believe that supplementation is unnecessary. Here combined with amino acids.
  • Guarana (300 mg): South American berry that contains caffeine which is listed here at 100mg. .Caffeine can increase the speed of the metabolism but effects often wear off once you become accustomed to it. There do not appear to be any other benefits to taking Guarana.
  • Theobromine (100 mg): The active compound in chocolate. It has a stimulant effect if taken in sufficient quantities and can increase the heart rate . 1 oz of dark chocolate contains 200mg of theobromine.
  • Green Tea Leaf (50 mg): Found to promote modest weight loss because the high levels of antioxidants. May increase the speed of the metabolism and the rate at which you burn off fat . This serving contains 14mg naturally occurring caffeine.
  • Garcinia Cambogia (125 mg): Much touted ingredient that lacks any real evidence that it works. Some clinical testing suggests it burns fat and reduces appetite because of HCA (hydroxycitric acid) but medical advice is that it requires further evidence and more stringent clinical testing.
  • Chitosan (125 mg): Natural fibre extracted from the shells and exoskeletons of shrimp, lobster and crab and is a fibrous material that is believed to block the absorption of dietary fat. It has undergone numerous clinical trials but all human testing proves the same thing: it does not work.
  • Gymnema Sylvestre (50 mg): Natural Australian herb that is unique in reducing the taste of sugar when the leaves are chewed.
    Research into this herb is ongoing. The preliminary results have been positive but it requires further testing for supplement use.
  • Banaba (1% extract) (25 mg): Plant extract believed to lower blood glucose levels. Research in very preliminary stages and no evidence that it works.
  • Calcium Pyruvate (50 mg): The body produces this substance when it breaks down sugar and it is also available in supplement form. It may help break down fat but it lacks evidence and requires clinical testing to prove this.
  • Apple Cider Vinegar powder (25 mg): Popular home remedy for everything from head lice to diabetes. However none of the medical claims have been scientifically proven and it can cause heart burn because of its high acidic content.
  • Grapefruit powder (25 mg): This natural fruit appears to have a direct effect upon the speed of the metabolism and is a good source of vitamin C. However, some research indicates that it may increase oestrogen levels – not good news if you have a hormone related medical condition. Requires further testing.
  • Coleus Forskohlii (powder) (25 mg):Much touted plant extract believed to stimulate thyroid hormones. May help increase testosterone but lacks clinical testing.
  • White Willow Bark (powder) (25 mg): Care needs to be taken before taking white willow root because it causes stomach problems especially bleeding. Aspirin is derived from white willow but has been modified to avoid this problem.
  • Uva Ursi (powder) (25 mg): This natural plant has a diuretic effect and lacks evidence regarding long-term safety. May interact with medication and can cause gastrointestinal side effects. It can also induce labour so should not be used if you are pregnant or trying to conceive.
  • Juniper Berry (powder) (25 mg): This natural berry is best known as the flavouring in gin but is also used in other food preparations and as a fragrance in cosmetics and soaps. Believed to lower blood sugar levels but has only undergone animal testing for this function.
  • Buchu Leaves (powder) (25 mg): South African plant extract that is a well-known herbal treatment for urinary infections and STDS although it lacks clinical evidence. It is a diuretic.
  • Cayenne Pepper (powder) (10 mg): Familiar culinary spice. This dose is equal to approximately 2 teaspoons, so about the same as an average chilli con carne! Cayenne may be effective for weight loss when taken at very high levels but unlikely to do much here.

So What Does All This Mean?

Looking at this extensive ingredients list, we cannot see that Therma Rip will live up to all the claims. Many of the ingredients lack clinical evidence that they work and although in some cases, preliminary testing has been carried out, very little here is actually proven.

Some of the claims do not even relate to the ingredients. There is nothing here that will raise adrenaline levels for example and none of the so called ‘glucose disposal agents’, such as Banaba have any proof of efficacy on humans.

However Therma Rip may have a diuretic effect and if you extremely sensitive to caffeine you may find that it perks you up for a while – that is until you get used to it.

Chitosan lacks evidence as an appetite suppressant and is believed to bind fat. However this comes with overwhelming evidence that it is not effective for humans although animal testing has been positive.

Does Therma-Rip Have Any Side Effects?

The greater the number of ingredients, the higher the risk of side effects so Therma Rip may cause a lot of potential side effects. Of course, your reaction to this supplement is individual and not everyone will experience problems.

We were unable to find any independent feedback so cannot bring you any true-life experiences.

Potential side effects may include:

  • Stomach upsets
  • Gas
  • Diarrhoea
  • Bloating
  • Irritation of the stomach lining
  • Increased risk of internal bleeding (white willow extract)
  • Heart burn
  • Acid Indigestion
  • Risk of an allergic reaction
  • Nausea
  • Sleeplessness
  • Jitteriness
  • Anxiety
  • Increased menstrual bleeding
  • Contractions of the uterus
  • Increase urine output
  • Increased heart rate and blood pressure

Avoid if you are pregnant, breast feeding or trying to conceive.

According to the product warnings you should avoid “If you have a known medical condition including high blood pressure, diabetes, any cardiovascular disorder, heart disease, and hyperthyroidism”.

We would also add that you need to avoid if you have or have had a hormone related medical condition such as breast cancer

Do not take if you are using prescription medication including anti depressants because this supplement will cause interactions.

Any Therma-Rip Reviews From Customers?

We have been unable to find reviews for Therma Rip. Monkey Nutrition encourage customers to leave reviews via the Trust pilot website but most of these appear to be for Primal – the Monkey Nutrition protein powder which seems very popular.

However, one customer reported,

Monkey products are good, I use Therma-Rip and Vitamin D3. I can honestly say the Therma-Rip works within a week, faster if you have a normal metabolism, mines a little slow.

Most of the other reviews praise the company generally such as,

Great company, nothing but positives to say about them…very fast delivery!

So Does Therma-Rip Work?

We can’t really see how it will work in the way as described but it is possible that if you use it as part of a weight loss regime it may help support your efforts.

The trouble is that it is crammed with unproven ingredients some of which may have little effect or even worse may cause side effects.

Take Chitosan for example. At 125mg, this is a principle ingredient but there is little evidence that it works on humans. In one test carried out by the University of California and titled ‘Chitosan supplementation and fat absorption in men and women’, the conclusion was that ‘For men, it would take more than 7 months to lose 1 pound of body fat.’

Garcinia Cambogia, another major ingredient is equally unproven. Despite the hype, there is little real evidence that Hydroxycitric acid burns fat.

There is a lack of customer feedback too. Strange when Primal an alternative Monkey Nutrition supplement is so obviously popular. Therma Rip is just not attracting the same positive attention.

Where Can I Buy Therma-Rip?

You can buy Therma Rip direct from the Monkey Nutrition website. One bottle of 90 tablets costs £22.00, which is 3 months supply and good value if you use as recommended and take one a day.

Shipping costs are not specified and you can pay via PayPal.

Monkey Nutrition are not operating any dodgy auto billing agreements. Although Monkey Nutrition sell direct to the USA and Europe we were unable to see the price in USD or Euros. The shipping costs and details were not provided but if you contact Monkey Nutrition they will undoubtedly be able provide this information.

What About A Guarantee

Monkey Nutrition do not advertise a money back guarantee.

Watchdog Verdict

We may have been a little harsh on Monkey Nutrition Therma Rip because there are some good points about this supplement.Firstly, it is very reasonably priced and the company seem reputable. You are not going to be tricked into a payment scam and there is plenty of good feedback for the Monkey Nutrition service.

In addition, it is not loaded with stimulants and many of the ingredients seem fairly harmless. However, the sheer number of different ingredients is a matter for concern because many of these do cause potential side effects, some of which are fairly obscure and quite dangerous.

However, this cocktail of ingredients will not cause all the health and weight loss effects that are mentioned in the advertising. There is just no evidence and we also have concerns that some of the high volume of ingredients may interact with each other. After all, this formula has never been tested so if you buy it you are essentially a guinea pig yourself.

Where is this supplement even made? The reference to the FDA is confusing from a British diet pill company and there are no guarantees that it is manufactured in the USA or the UK.

Usually supplement companies are quick to point out the country of origin – that is unless a product is manufactured in a place that they would rather us not know about! We have however been unable to find out this information.

All things considered we feel that Therma Rip simply does not come up to scratch so have no other choice but to reject this supplement.
