Watchdog Approved Diet Pills

Whenever we see something “revolutionary” our interest is always aroused, it’s not very often that anything in the diet pill world is truly revolutionary so what makes Quantrim any different?

We take a close look at Quantrim and see whether it lives up to its claims. Is it finally the answer to your weight loss dreams or another case of the hype being much bigger than the reality?

After we finally found the merchant site we could get down to doing an objective review of Quantrim.

First impressions were not really encouraging, with a pretty average looking website. Not a problem though, some of the best products are featured on poor quality sites and some of the biggest scams are on the prettiest sites. So we can’t read a lot into that at all.

It’s a fairly bland looking front page with not a lot of information, just a load of badges, and a stock image of a Doctor saying it’s “Medically Approved.” Very interesting, we thought. It’s extremely rare for a product like this to be medically approved so good to see some evidence to back this up.

Once we dig a bit deeper though, there is quite a lot of information on other pages of the site, so the lack of information at first glance is not too bad for people like us wanting some solid facts.

Quantrim Concerns:

  • No indication of Iodine content
  • Excess Iodine could be dangerous for some individuals
  • None of the ingredients have any clinical evidence they are effective for weight loss

So What Is Quantrim and What Are The Ingredients For Quantrim?

This is the main selling point of Quantrim, as it is said to be a “traditional herbal remedy.”

It only seems to contain two ingredients from what we could see: Bladderwrack (Fucus vesiculosis) and Cleavers (Galium aparine).

  • Bladderwrack (Fucus vesiculosis): Good old-fashioned seaweed, which is naturally high in Iodine. It is said that we need Iodine to create “Thyroid Stimulating Hormone (TSH). This is what gives us a healthy metabolism.

Seaweed is also claimed to create a full feeling in the stomach to reduce appetite. Rather bizarrely they also say that it helps to prolong the menstrual cycle and exert anti-oestrogenic effects in pre-menopausal women. We have no idea what this has got to do with a slimming pill and what effect it might have on those of us who are not pre-menopausal.

Rather handily they have provided links references to several clinical studies, but none of them have anything whatsoever to do with weight loss in normal healthy human beings.

The references relate to several medical conditions including; hyperthyroidism, menstrual cycle length, antithrombic activity and antitumor activity.


Don’t worry so are we, we could not find any peer reviewed clinical evidence that has ever been published to show that Bladderwrack can help with weight loss.

We would suggest that unless you are suffering from Goitre (hyperthyroidism) or you are pre-menopausal with abnormal menstrual cycles that you should avoid the need to take high doses of Iodine.

There have been several concerns with taking excess Iodine:

High intakes of iodine can cause some of the same symptoms as iodine deficiency—including goitre, elevated TSH levels, and hypothyroidism—because excess iodine in susceptible individuals inhibits thyroid hormone synthesis and thereby increases TSH stimulation, which can produce goitre.


It appears that Quantrim contains 40mg of a 5:1 dried extract of Bladderwrack. This is equivalent to 200mg of dry extract. At the recommended dosage of 3 tablets a day this is equivalent to 600mg daily serving. It is not indicated how much Iodine is in the product.

We leave the last word to the US National Library of Medicine:

The effectiveness ratings for BLADDERWRACK are as follows:

Insufficient evidence to rate effectiveness for….
Obesity. Early research suggests that Bladderwrack, used along with lecithin and vitamins, doesn’t help people lose weight and keep it off.


  • Cleavers (Galium aparine): A common weed, prolific in the UK, which also goes by the names of Goosegrass and Stick Willies. No real clinical research has been conducted on Cleavers but is considered to have traditional uses as a diuretic. It is also said to have laxative effects.

No research has been done into any weight loss effects any form of Cleavers may have. Traditionally it is consumed as a tea made from the leaves of the weed. It is then said to act on the lymph system to cleanse the bloodstream of toxins.

Quantrim contains 50mg of a 4:1 extract giving a dosage of equivalent to 200mg. At the recommended dosage of 3 tablets a day this is equivalent to 600mg daily serving.

We could find no evidence for the use of a dried extract of Cleavers for any conditions.


Does Quantrim Have Any Side Effects?

As mentioned, high does of Iodine can be increase the risk of adverse reactions. Without any indication of the exact daily serving then those susceptible to high Iodine ingestion should exercise caution. Bladderwrack also contains align, which as laxative effects.

With regards to the other ingredient, Cleavers, then as it is a diuretic we would also advise caution. We have written extensively about the use of diuretics and laxatives as a slimming aid HERE with the conclusion that they are not advised to be used for extended periods of time.

The merchants advise consuming Quantrim after a meal with a “big glass of water.” This would negate the effects of Cleavers as a diuretic so we are not sure what the actual effect of the ingredient would actually be. It would be good to see some hard facts in this area.

Caution: You are not advised to take Quantrim if you’re breastfeeding or a nursing mother and recommended to seek medical advice if you have a pre-existing medical condition.

Any Quantrim Reviews From Customers?

Because Quantrim is so new there are no real customer testimonials at this time. This is normal with a new product and is not of any particular concern.

We did find some suggestions that Quantrim has been used by Victoria Beckham, however this appears to be the work of someone with an over-active imagination, rather than an actual fact. There is no suggestion that the claims have anything to do with the merchant.

So Does Quantrim Work?

We really wanted to see something special from Quantrim as it promised to be so “revolutionary.” Unfortunately we cannot find any reason to suggest Quantrim actually work’s. There is no evidence to suggest that Iodine (Bladderwrack) has any effect on weight loss for normally healthy people.

Likewise there is no evidence or research to suggest Cleavers can also help with weight loss. It’s main traditional use is as a diuretic, which we would not recommend, and we could find nothing to suggest a dried extract could be useful as a slimming aid.

Despite claiming that Quantrim is “revolutionary” the website then goes on to say that it has been used in the same format for over 100 years:

Quantrims particular combination formula of bladderwrack and cleavers has a long history of use, stretching back over 100 years. It was first made by the herbalist William Box who founded a herbal manufactory in Devon in 1875. His pills were famous and he was awarded two Gold Medals and three Distinction Awards in the Paris Exhibition of 1912 for his work. His slimming pills, the exact same formula as Quantrim, were called Slimwell Anti-Fat Slimming Tablets. William Box also made these tablets for his friend and colleague Duncan Napier, a famous Victorian herbalist whose tablets were simply called Napiers Anti-Fat Pills! Duncan Napiers also made a liquid version called Duncan Napiers Corpulency Compound.

Quantrim does come with a handy diet plan by a Dr. Alfred, which may well help some people with their weight loss goals. Without seeing full details we cannot how effective the plan might be, but it’s good to see something like this offered with the product.

Where Can I Buy Quantrim?

At the moment Quantrim is only available online from the main merchant, who appear to be Nuropharm Ltd based in Cyprus. There is also an address for queries in Glasgow, UK.

These details are helpfully provided on the website as well as telephone contact numbers.

What About a Guarantee?

We were pleased to see a full 60-day money back guarantee.

It doesn’t look there are any catches with the guarantee, only a standard £15 handling charge which is pretty normal in this industry.

Reading through the rest of the terms and conditions there is nothing of any concern.

Prices seem fairly good at £34.95 for one bottle with discounts for larger packages.

Watchdog Verdict

We had high hopes for Quantrim but to be honest we were left just a little bit disappointed.

We just couldn’t find anything to suggest it could work for weight loss, based on the ingredients used. The main concern was the warnings about Bladderwrack from the National Institute of Health, which rates it thus: “insufficient evidence to rate effectiveness.”

We would love to see much more detail provided and a link to any sort of study that shows either of the ingredients can be beneficial as a diet aid.

It’s great that this product is based on an ancient slimming remedy but until we have modern evidence it works we have no alternative but to reject Quantrim.

    I saw this product featured on the Daily Mail website recently and have to say even if it is true that Victoria Beckham does use them it’s not going to sell them to me as I think she looks way too skinny. I would much rather look healthy and would be more tempted to try these if someone with a more realistic ‘end result’ body was linked to them.

  2. Sally says:

    Haha Jo, couldn’t agree with you more. I saw this on the Mail online as well and had to laugh. There’s no way on earth she would ever use these things and like you say it would only put me off if she did. She’s probably the opposite of what every woman wants to look like and apart from that she just looks miserable anyway.
    Glad I found this proper review of quantrim and found out the real truth. I looked on google but all i could find was a load of fake sites spouting the same rubbsih as each other. Think this whole thing is one big con to be honest, glad the watchdog doesn’t approve them or I would probably lose faith in mankind :)
    Keep up the work guys.

    Glad I found this site. Info very helpful

  4. Sam says:

    Thank you for the review. I am also skeptical about this product and the main reason I didn’t go ahead and order it is because, as you mentioned, the lack of Iodine content info, which was my main concern, however, just realized that the website DOES have that information:

    “A: Yes Quantrim does have iodine. Iodine is one of the naturally occurring minerals found in Fucus seaweed. It is found at a maximum of 0.10% of the extract in the form of chelated iodine. This is equivalent to 40 mcg (micrograms) per tablet. At the maximum dose of 3 tablets per day, the iodine intake would be 120 mcg of iodine. The US Institute of Medicine considers 1100 mcg iodine per day to be the safe upper limit. It is based on iodine in the form of potassium iodide which is treated very differently by the body than the natural chelated iodine found in seaweeds. One teaspoon of iodised salt contains about 400 mcg of iodine from potassium iodide. The amount in the tablets is well within the safety limit of 1100 mcg per day. The current RDA (Recommended Daily Allowance) (minimum intake) is low at 150 mcg per day (220 mcg for pregnant women and 290 mcg for breastfeeding women).”

    So basically my main worry, if it is safe, is alleviated. What is left from your recommendation of rejection is 1) no proof if it works 2) it can be laxative, which a lot of the herbal medicine can be. With the Iodine issue cleared, I would honestly take my chances as it doesn’t seem to harmful. At the end of day, it is a UK manufactured product. How bad could it be?! I am surprised that the reviewer didn’t look close enough at the Iodine content issue and just plainly rejected it as one of the main issues and I am glad I did my own research.

    Appreciate some feedback on the above.

      Hi Sam,

      We really appreciate your feedback and comments.
      When we first looked at the product and did the review the information you have posted was not available, it has been added since and as such we never received any indication from the merchant that they had addressed our concerns and added to the website. The review was in our opinion a completely accurate and independent analysis of the information revealed at the time.
      This often happens and we have many instances of merchants changing their websites sometimes on a daily basis. As such unless we are informed by either diligent people like yourself or the merchants directly then we would find it impossible to go through every product we have done every single day to check if they have changed anything.
      When we can schedule it in to our timeframes we can take another look and see what else they have changed and update the review accordingly.
      Once again many thanks for bringing this to our attention, with the help of feedback from consumers like yourself we can keep the Watchdog the primary source of independent reviews on diet supplements. We like to think we are keeping the merchants on their toes, in order to protect consumers, so the more help we get the better. :)

    I just don’t understand why legitimate sites like Fox News, Glenn Beck, and the ohters listed in there “as seen” section allow this company to advertise their products. As soon as I saw the add, I knew it was a scam, too good to be true, but was amazaed to see it avertised on a legitimate news site (even if you don’t agree with its political views, it is still legitimate). By accepting these ads, and allowing htem to use their logo and “as seen on” as part of their site, they add more legitimacy to this product.
