Slimming Supplements: Dangerous Brands and Ingredients


It’s really tempting to opt for the quick fix when it comes to losing weight. We get it. A quick search on Google will bring up a plethora of tempting supplements promising to be the ‘miracle’ you are looking for.

We would advise extreme caution though. The ingredients in some of these supplements can be dangerous, even deadly!

Our advice would always be to not take these kinds of supplements. But why? Are we just being party poopers?

Let’s find out more

The ingredients below are or have been marketed for weight loss but are considered dangerous. Some are banned and others shouldn’t be taken without medical supervision.

DMAA (1,3-dimethylamylamine or methylhexanamine)

First introduced as ‘Geranium Oil Extract’ this is a neurological stimulant and is used in ‘party pills’.

Touted as a ‘natural stimulant’ lab tests have yet to find any DMAA in geranium oil. Hmmmm, interesting.

It mimics adrenaline and has been linked to cerebral haemorrhage.

Other issues reported include:

  • Elevated blood pressure
  • Seizures
  • Risk of serious cardiovascular issues
  • Arrhythmias
  • Heart attacks
  • Strokes
  • Panic attacks
  • Erectile Dysfunction

DMAA has been banned by the FDA in America and various sports organisations because of its amphetamine-like nature. At least 3 cases of fatal cardiac arrest have been reported after taking this supplement.

Supplements that contain DMAA:

  • LX1
  • OxyElite Pro
  • Jack3d
  • DMAA may also be listed on product labels as:
  • 1,3-DMAA
  • 1,3-Dimethylamylamine
  • 1,3-Dimethylpentylamine
  • 2-Amino-4-methylhexane
  • 2-Hexanamine, 4-methyl- (9CI)
  • 4-Methyl-2-hexanamine
  • 4-Methyl-2-hexylamine
  • Dimethylamylamine
  • Geranamine
  • Methylhexanamine
  • Methylhexanenamine


This supplement has been attributed to at least 63 published deaths. You might remember the death of Uni student, Sarah Houston back in 2012?

This was due to taking DNP that she bought online, alongside anti-depressants.

DNP is designed to increase heat production on the body’s cells. It accelerates the metabolism but to dangerously fast levels. Even the smallest overdose of the stuff can cause death because of its high toxicity.

DNP is banned for human consumption in several countries including the UK. It was originally used as a key ingredient in dyes, explosives and pesticides. It can still be legally used as a pesticide. That says it all really doesn’t it?

Other side effects can include:

  • Cataracts
  • Liver failure
  • Rapid or irregular heartbeat
  • Damage the nervous system
  • Skin lesions
  • Fever
  • Insomnia
  • Very high temperature

DNP is also known as:

  • 2,4-dinitrophenol
  • Dinosan
  • Dnoc
  • Solfo Black
  • Nitrophen
  • Aldifen
  • Chemox


Bumetanide is a strong diuretic ('water pill') and can cause dehydration and electrolyte imbalance.

If it is prescribed for you, it is important that you take it exactly as told by your doctor. If you experience any of the following symptoms, call your doctor immediately: rapid, excessive weight loss; decreased urination; dry mouth; thirst; nausea; vomiting; weakness; drowsiness; confusion; muscle pain or cramps; or rapid or pounding heartbeats.

Supplements found to contain Bumetanide

  • Starcaps

Fluoxetine (Prozac)

Fluoxetine is used to treat various mental illnesses. These include depression, bulimia, OCD, panic disorder and premenstrual dysphoric disorder. It's classed as an SSRI (selective serotonin reuptake inhibitor). In the UK, it is normally only available on prescription from your GP.

Uses of drugs like this have been associated with some serious side effects. Common issues include:

  • Feeling sick
  • Headaches
  • Being unable to sleep
  • Diarrhoea
  • Feeling tired or weak

Serious side effect can include:

  • Headaches, trouble focusing, memory problems, not thinking clearly, weakness, seizures, or losing your balance
  • Thoughts about harming yourself or ending your life
  • Chest pain or pressure, or shortness of breath Severe dizziness or passing out
  • Fits, feelings of euphoria, excessive enthusiasm or excitement, or a feeling of restlessness that means you can't sit or stand still
  • Putting on or losing weight without trying to
  • Changes in your periods such as heavy bleeding, spotting, or bleeding between periods
  • Painful erections that last longer than 4 hours - this may happen even when you are not having sex

The problem with supplements is that the person you are buying from doesn't know what other medications you are on. Taken alongside drugs like aspirin and ibuprofen can have serious consequences. It's also a real issue if taken with other antidepressants, drugs for bipolar, blood clots, chemotherapy and heart conditions.

Lorcaserin is not currently available legally in the UK> In May 2013, the company withdrew its request for marketing approval because it couldn’t address the issues raised by the CHMP (Committee for Medicinal Products for Human Use).

Lorcaserin has been known to cause psychiatric issues, impaired attention and issues with memory.

Use of Lorcaserin alongside other medications may result in potentially life-threatening drug interaction.

However, due to a recent study, experts have hailed the ‘promising’ findings as ‘exciting’ in regards to Type 2 Diabetes. That said, more research is needed into this drug before it is used for anything because of the side effects.

Supplements found to contain Lorcaserin:

  • B-Lipo
  • Green Algae Combination by Crane Beauty
  • Yanhee Slim


Phenolphthalein has previously been used as a laxative, but is no longer authorised for sale in the UK as it may cause cancer. Health risks associated with phenolphthalein could include potentially serious gastrointestinal disturbances, irregular heartbeat, and cancer with long-term use.

WLR’s Advice

  • Don't take them!
  • Don't buy anything that's not available from a reputable chemist or source you know and trust
  • Don't buy false promises - if something claims you'll lose 10lbs in a week by taking it, it's either outright lying or dangerous
  • Always be very cautious when you start taking a new supplement, if you are in any doubt at all, consult your doctor
  • People who are taking other medications, or are in current treatment for any condition, should not take dietary supplements without medical advice

Don’t assume though that because an ingredient isn’t on this list that it isn’t dangerous. These products come and go with new names and new ‘formulations’.
