Made by a South African company called Loock Pharmaceuticals, ReliSlim Original provides you with d-Norpseudoephedrine HCL to helps suppress your appetite and make it easier to stick to your low-calorie diet. The idea looks good, but the question is, should you really be trying something that includes a banned ingredient? Is it really effective? Here is our review to help you decide.


  • May help reduce appetite
  • Sometimes effective for women
  • Does not contain additives


  • No complete list of ingredients
  • Rarely effective in men
  • Expensive
  • Causes several side effects
  • Not a proper fat burner
You can find so many dietary supplements and pills to boost weight loss and ReliSlim Original is yet another option you can try in this regard. Made by Loock Pharmaceuticals, it is supposed to work by suppressing your appetite. It is not really a dietary supplement because you can get it only after your doctor’s prescription, and that is mainly because its main ingredient is pseudoephedrine, a stimulant usually found in OTC decongestants. It helps reduce your appetite, so you could follow your diet plan more effectively and lose weight in return.

ReliSlim Original Overview

What you need to know about ReliSlim Original

ReliSlim Original is supposed to work better as compared to its sibling, ReliSlim Herbal, which provides you with some natural ingredients, like green tea extract, caffeine, and more. It contains pseudoephedrine, which is supposed to suppress appetite and increase fat oxidation in the body.

It is a schedule-6 medicine, so you cannot get it without a prescription. To get good results, you still need to follow a good diet plan and stick to a suitable exercise program.

What are the side effects of ReliSlim Original?

ReliSlim Original can cause several side effects, even when taken as directed, and that is mainly due to pseudoephedrine. Some of the most common side effects are insomnia, headache, nausea, and nervousness. You may also experience increased heartbeat and elevated blood pressure. Check out the “Side Effects” section for further details.

How much does ReliSlim Original cost?

You will end up spending £95 to get one bottle of ReliSlim Original. You can get 30 tablets or 90 tablets per bottle.

ReliSlim Original Key Features

ReliSlim Original is designed for people struggling to deal with obesity. This weight loss pill contains d-Norpseudoephedrine HCL, which is a chemical version of ephedrine or ephedra. Though banned in many countries, pseudoephedrine is supposed to work by suppressing your appetite. It is essentially an appetite suppressant and does nothing to boost your metabolism or burn fat directly. Should you really be putting your money on ReliSlim Original that relies only on pseudoephedrine to produce results? Let’s find out.

ReliSlim Original Key Points

  • Appetite suppressant
  • 30 tablets and 90 tablets

ReliSlim Original contains pseudoephedrine, which is a purified form of ephedra, a herb widely used in Traditional Chinese Medicine. Some studies show that ephedra may help treat bronchitis, asthma, and hay fever, and relieve symptoms of flu and cold, including nasal congestion, chills, fever, and cough. Many OTC remedies now include synthetic ephedrine compounds, such as pseudoephedrine. You can also find this ingredient in weight loss supplements, such as ReliSlim Original, but it is important to understand that the information regarding the effectiveness of pseudoephedrine for energy, weight loss, or athletic performance is controversial and inconclusive. In fact, the FDA has banned dietary supplements that may contain ephedrine, ephedra, ma huang, norephedrine, pinelllia, or Sida cordifolia.

It is a fact that pseudoephedrine is not as potent as ephedrine, but it can still affect your central nervous system. As it is a stimulant, you may notice some effects in the beginning, but you may develop a tolerance against it, which makes it less effective over time. Moreover, there is not enough scientific evidence to confirm that regular intake of pseudoephedrine can help suppress appetite and trigger fat loss. Some studies show that ephedrine does not work when used without caffeine. For example:

For example, in a double-blind, placebo-controlled trial, 180 overweight individuals were placed on a weight-loss diet and given either ephedrine/caffeine (20 mg/200 mg), ephedrine alone (20 mg), caffeine alone (200 mg), or placebo, 3 times daily for 24 weeks. The results showed that the ephedrine/caffeine treatment significantly enhanced weight loss, resulting in a loss of more than 36 pounds as compared to only 29 pounds in the placebo group, a 7-pound difference. Neither ephedrine nor caffeine alone produced any benefit.

It is worth mentioning that even if pseudoephedrine offers some benefits, you may not get any from ReliSlim Original mainly because it does not provide you with enough of this stimulant in the first place. You get 20mg of pseudoephedrine from each tablet of ReliSlim, but many studies have found that you should start with at least 120mg of pseudoephedrine to get any results.

The company states that ReliSlim Original helps lower the levels of cortisol, but studies show that the purified versions of ephedra (pseudoephedrine and ephedrine) work by raising cortisol levels. You feel less hungry when your cortisol levels are up, but taking ephedra-based weight-loss supplements would lead to chronically high cortisol levels, which is going to cause several complications. You may actually experience severe consequences if you do not pay attention to maintaining a balanced diet at the same time.

How to Take ReliSlim Original

Each tablet of ReliSlim contains 20mg of pseudoephedrine. You should talk to your doctor before using ReliSlim. However, here is what the official site states in terms of use:

Take one capsule with a full glass of water, three times per day: morning, mid day and early evening. You may take ReliSlim with or without food. Do not exceed 3 capsules per day.

Even if ReliSlim works to suppress appetite, it is not going to make any significant change in your weight in a short time. By suppressing your appetite, you may be able to follow a low-calorie diet more efficiently, but you are going to see results if you limit your caloric intake for long enough. That may not be a great idea though, as using ReliSlim Original for long can lead to several side effects, mainly due to its pseudoephedrine content.

ReliSlim Original Concerns

  • Proprietary blend
  • Several side effects
  • No money-back guarantee
  • Very expensive

Another issue is that even if you continue to use it for a while and end up losing weight by eating less, you may not be able to maintain that weight. Supplement manufacturers state that appetite suppressants help you feel less hungry, so you can consume less simple carbs, less fat, and fewer calories. Over time, it will become a habit, and you will continue to eat less even after eliminating the appetite suppressant. That does not happen in the real world though. Many customer reviews have mentioned that your appetite returns strongly once you have stopped taking ReliSlim Original, and that means you may put on all the weight back along with some more after you discontinue the use of these weight loss pills.

It is also important to keep in mind that you are not going to get any results just by suppressing your appetite. You need to pay special attention to following a balanced diet and sticking to a good exercise program. You may not feel hungry after you start taking ReliSlim Original, and if you do not know what to eat, you will end up experience several health complications because your body would not be getting enough nutrients. Cutting calories is certainly helpful, but that can be dangerous if you also cut the amount of essential nutrients that your body need to function properly. Therefore, ReliSlim Original is never a good choice for anyone not already aware of how to follow a healthy diet plan.

The side effects associated with the use of pseudoephedrine make it difficult to use it on a long-term basis. Considering the customer reviews, it becomes clear that increase heartbeat and headaches are some of the most common side effects associated with ReliSlim Original. Not everyone is going to experience these effects, but many people just cannot tolerate ephedrine in this form and end up experience side effects. The company suggests that you should drink plenty of water while taking ReliSlim Original or else you may end up dealing with a dry mouth or dry mucus membranes. It can also interfere with your sleep if you take it late in the day.

Even if you assume that ReliSlim Original reduces your appetite and helps lower your caloric intake, it is never a good idea to spend so much money just to get an appetite suppressant. You have to pay £95 to get ReliSlim Original, but you can easily get other appetite suppressants with scientifically proven fat burners and appetite suppressants at a much lower price. You can save that money as well and spend more time in the gym and follow a healthy diet plan to lose weight in a healthy way without having to worry about any side effects, which are usually associated with products like ReliSlim Original.

What does ReliSlim Original claim to do?

ReliSlim Original is a weight loss tablet that works by suppressing appetite. You can get good results only when you combine it with a healthy diet plan and an appropriate exercise program. Here are some of the claimed benefits of ReliSlim Original:

  • Suppresses your appetite to prevent overeating
  • Lowers stress in a short time
  • Improves your mood
  • Gets rid of abdominal fat
  • Loses weight in a short time

Does ReliSlim Original work?

It may work for some people, especially in the beginning, but it can lead to some serious side effects over time. ReliSlim Original contains pseudoephedrine, a substance banned in many countries. It works by suppressing your appetite, but unfortunately, appetite suppressants work for a short time only and your appetite is likely to come back strongly once you stop taking them. The same is the case with ReliSlim Original. There is also no reliable scientific data to confirm that taking as little pseudoephedrine as found in ReliSlim can lead to a significant reduction in your weight. Therefore, we believe that you will be better off trying a weight loss supplement with some natural fat burners, such as caffeine, green tea extract, yohimbe, carnitine, ALA, etc., to help burn fat efficiently.

ReliSlim Original Ingredients

There is not enough information about the ingredients found in ReliSlim Original, but the main active ingredient is D-Norpseudoephedrine HCL.

Pseudoephedrine is a synthetic form of ephedrine and is a sympathomimetic compound that may help suppress appetite. It may aid in weight reduction when you use it in combination with a low-calorie diet and exercise program. The stimulant actually works by affecting hypothalamic appetite centers in your brain – the use of anorectic agents helps to manipulate the system. ephedrine, pseudoephedrine, and phenylpropanolamine increase the concentrations of norepinephrine adrenergic neurotransmitter, which may result in decreased food intake.

Unfortunately, there is no reliable scientific research to confirm that pseudoephedrine can suppress appetite to an extent that it results in weight loss. Moreover, there may be certain side effects associated with the use of pseudoephedrine and any ephedra-based weight loss supplement.

ReliSlim Original Side Effects

ReliSlim Original works by suppressing appetite, but it contains pseudoephedrine, which is banned in many countries because of certain side effects.

You may end up experiencing serious consequences when you take pseudoephedrine on a long-term basis. The effects can be serious when you combine it with caffeine. The combination is not safe for individuals with heart disease – it can also affect people with no existing heart conditions. You should be very careful when taking ephedra-based weight loss supplements, as they are associated with inflammation of the liver and the heart. It can actually trigger an autoimmune reaction and lead to serious problems.

As it serves as a stimulant, it can produce side effects such as anxiety, restlessness, irritability, nausea, headaches, and vomiting. Pseudoephedrine may sometimes lead to urinary problems. Other serious side effects include rapid heartbeat, high blood pressure, seizures, stroke, and even death.

It is important to avoid ReliSlim if you have cardiovascular disease, such as high cholesterol, hypertension, angina, intermittent claudication, or abnormalities of heart rhythm. People with hepatitis, diabetes, glaucoma, vasculitis, hyperthyroidism, and diseases of the nervous system should also avoid it.

Caution: Not suitable for individuals under 18 years of age. If you are pregnant or breastfeeding, consult a doctor before using this product. If you are taking any medication, or have any type of medical issue, consult with a doctor before using this product.

ReliSlim Original Customer Feedback

You cannot find many customer reviews for ReliSlim Original, but whatever we could find was not impressive either. For instance:

I have been using it for a few weeks but it seems to have no effect on my weight.

I stopped using it after a few days because it gave me some serious headaches with nausea.

How long does ReliSlim take to work? It’s been six weeks and no results yet!

I do not think it really works, and it is very expensive too.

ReliSlim Original Money-Back Guarantee

No, it does not come with a money-back guarantee, which may serve as a deal-breaker for many.

Where To Buy ReliSlim Original

ReliSlim Original is manufactured by a South African company, but is shipped anywhere in the UK. Several third-party retailers also stock ReliSlim.

Watchdog Verdict

ReliSlim Original is supposed to work because it contains pseudoephedrine. It is true that pseudoephedrine is quite like its chemical relative ephedrine when it comes to stimulating the central nervous system and suppressing appetite as a result. It works by narrowing blood vessels and increasing your heart rate. It is supposed to burn fat when your heart rate and blood pressure is up, but that is certainly not a highly recommended way to lose weight.

Moreover, appetite suppressants can only serve as a short-term weight loss solution and lose their effectiveness over time; in fact, many people say that their appetite comes back strongly once they stop taking ReliSlim Original. You require a doctor’s prescription to get it, which can be an issue, and it costs you some good money (£95). So, avoid it and look for a weight loss supplement with true fat burners and scientifically proven ingredients.

Overall, we do not recommend ReliSlim Original to our readers.
