Zantrim seems to want to be both a thermogenic fat burner and an appetite suppressant. Whilst some of the ingredients look alright (and safe) they also seem somewhat under-dosed. There is said to be a money-back guarantee, but there really isn’t – there is just the standard returns policy for unopened products, which is required by law.


  • Claims supported by the EFSA (European Food Safety Authority)
  • Suitable for vegetarians
  • Free UK delivery from the eBody website on orders over £30


  • Possible under-dosage of ingredients
  • Contains some ineffective ingredients
  • Some Amazon reviews claim it has given them a headache or made them feel dizzy
It can be hard for anyone of any age to lose weight, but as you get older, your metabolism tends to slow down. Many people may consider a supplement which increases metabolism and energy, reducing the urge to snack or binge eat. Zantrim claims to be one of these, designed to help men and women reach their weight loss goals faster with daily use.

Let’s take a look at Zantrim to see if it really is all it says it is.

How to Take Zantrim

To check your tolerance for these diet pills, start by consuming just one capsule a day of Zantrim. Once you have assessed your tolerance to the caffeine, you can increase your intake to one capsule twice per day. Capsules need to be consumed on an empty stomach, or at least 30 minutes before eating, and a minimum of six hours need to be left in between your first and second dose. It is recommended that the second dose is taken at least four hours before you intend to go to bed, to ensure that sleep patterns are not affected.

Zantrim Concerns:

  • Not enough of the core ingredients to have the desired effect
  • Concerns that the returns address is a ‘care of’ address
  • Can only return unopened products – this is not a true money-back guarantee, but a legal requirement

What does Zantrim claim to do?

The manufacturers of Zantrim make the following claims about the product and how it works to aid weight loss:

  • Proven to support metabolism and energy
  • Stops people from binge eating and snacking
  • Fast stimulation boost
  • Easy to swallow, vegetarian capsules

Does Zantrim work?

eBody’s claims that Zantrim supports metabolism and energy are supported by the EFSA, so there has to be some benefit to taking them. The ingredients in the supplement are ones that are known to be reliable for weight loss, but there are definitely better products out there. The caffeine is a great start to the list of ingredients, as it is well documented that this will kick-start metabolism and curb hunger. It’s also the best natural stimulant around. The other ingredients generally all support weight loss so if taken correctly, yes, it could work, and reviews on Amazon and the eBody website support this by helping the consumer to stick to a lower calorie diet plan by reducing hunger.

However, we believe that some of the ingredients are underdosed and that the recommended dosage is too low to be as effective as it could be. The L-Carnitine is under-dosed, and the CLA and Phenylethylamine won’t have much of an effect at all. The addition of a thermogenic like cayenne pepper and a suitable appetite suppressant such as Glucomannan would make this a much better product for weight loss.

The most popular appetite suppressant in 2021 is Phentatrim.

Its ingredients are scientifically proven to aid weight loss and you are covered by a full 60-day money-back guarantee from a trusted company, making Phentatrim a very popular choice in the diet world.

Phentatrim is the best thing to hit the supplement market in a long time, with thousands of customers already seeing the benefits. That’s why it's our editor's top pick.

Zantrim Ingredients

  • Caffeine Anhydrous 200mg: Caffeine is a well documented natural stimulant and is supposed to work by activating certain pathways involved in metabolism. It blocks adenosine receptors and ensures that adenosine stays active for an extended time. This can help keep you active and energized for longer periods.
  • Kola Nut 175mg: This ingredient just gives an added boost to the caffeine.
  • Green Coffee Extract 150mg: There is not a large amount of research on the weight loss properties of Green Coffee Extract, but a recent French study though does suggest that supplementation of Green Coffee extract for 60 days may cause 5.7% reduction in body weight. This is because it contains Chlorogenic Acid, which is a nutrient which helps to reduce your overall levels of the glucose in your liver. This glucose is what your body uses for energy, the less of it you have in your system, the more stored fat your body burns to make up the difference.
  • Guarana Extract 75mg: This contains trace amounts of caffeine, but more importantly, a range of general antioxidants which can help to promote overall health. It won’t do anything for weight loss but is a great ingredient to have in there, nevertheless.
  • L-Carnitine L-Tartate 50mg: This is an amino acid which has been seen in many studies to help increase energy and metabolism. However, studies also suggest you need a lot for it to work. It’s recommended that you have 500 – 2500mg per daily serving, and with only 50mg per serving in the product, you’re unlikely to get enough for it to be beneficial.
  • Green tea Extract (95% Polyphenols) 50mg: This is important due to the anti-oxidants in this herb known as catechins. Once absorbed by your body, catechins have been seen to help improve your overall levels of norepinephrine, the fat burning hormone. The more norepinephrine you have in your body, the more support you’ll have to burn fat. This is probably one of the best ingredients in the supplement.
  • D.L Phenylalanine 37.5mg: Phenylalanine is an amino acid which has been seen to promote the happy hormones in your body like serotonin and dopamine – which can help with focus and concentration. However, studies have shown that when taken orally, as it is in Zantrim, this amino acid is broken down too quickly for it to be absorbed.
  • Conjugated Linoleic Acid 5mg: CLA is a stimulant-free fat burner that is used by several weight-loss supplements. It’s believed to influence certain receptors in your brain to help fat loss, although studies have shown that the impact is negligible and unlikely to make a difference.
  • Chromium Picolinate 13ug: Often found in weight loss supplements and it does work. It helps to regulate blood sugar and insulin levels. Insulin determines how much fat is stored after consuming a meal, so the more you have in your system, the more fat you will store.

Zantrim Side Effects

There is very little information available about the potential side effects that could be caused by Zantrim. There aren’t any listed on the website, although some Amazon reviews report dizziness and headaches after taking them.


Do not exceed the recommended dosage allowance. Do not exceed more than 2 capsules per day. Only use as directed.

Zantrim Customer Feedback

There are currently 88 verified purchase reviews from customers on Amazon. 82% of the reviews give Zantrim four or five stars, with many claiming it has kick-started their weight loss after reaching a plateau. 13% of the reviews are 1 star, with comments such as ‘it didn’t work’ and several claiming it gave them a headache or made them feel dizzy. The testimonials on the official eBody website are all positive, which is to be expected.

Zantrim Money-Back Guarantee

eBody offer a 14-day money-back guarantee on unopened products, which technically means it is nothing more than just a returns policy. This is described on their website as follows:

When buying online from us we want to be sure your 100% happy with your purchase, so that’s why we offer a 14 day money back guarantee on any products you buy from us, all supplements must be in the original packaging with seals intact (if you open any supplements we can not unfortunately take them back) for any equipment purchased it must be in immaculate condition and in its original packaging.

Where To Buy Zantrim

Zantrim is currently available to buy from Amazon, or from the official eBody website for the same price (£22.95 for 60 capsules).

Watchdog Verdict

It’s certainly a positive that Zantrim contains all natural ingredients and there are no side effects. We also are happy with the fact that it is produced in the UK and so meets safety regulations. Whilst there are some reviews supporting the claims and that it is supported by the EFSA, we believe that the product contains some unnecessary ingredients and that the amount of each ingredient is not enough to be as effective as it could be.

With this in mind, we think there are much more useful appetite suppressing supplements on the market and as such, we do not recommend Zantrim to our readers.
