Slim Me 3 Days, 5 Days, 14 Days and 28 Days Review

Slim Me is a two-part weight management kit made in the UK by GP Nutrition.

It sold by the box and each box contains two types of sachets.

The first type of sachet contains an appetite suppressing gel, the other type contains three capsules intended to be consumed together as a single dose.

Slim Me is not a cheap product to use, so the price does not work in its favour.

However, although some diet pill manufacturers try to shield their identity and hide away from the world, that’s not the case with GP Nutrition.

Slim Me

It’s a pretty high profile company and when it launched its first products in early 2018, the story was picked up by many UK tabloids.

The reason the mass media was so interested is probably more due to the company’s founder than its products.

The lady who put the “GP” into GP Nutrition is a Czech fashion model.

Her name is Gabriela Peacock and the move over to the weight loss industry was not a particularly hard one for her because she’s also a qualified nutritionist.

Advertised Benefits

According to the front of the box, people who buy Slim Me can expect three main benefits:

  • Reduced hunger cravings
  • Metabolism optimization
  • Help with weight management

Usage Guidelines

The pills are taken once per day, in the morning. The gel has to be mixed with water and taken three times a day and it’s important the doses be consumed 20 minutes before meals.

Key Ingredients – What’s in it?

The key ingredient in Slim Me gel is glucomannan.

When it’s taken with water the natural fibers it provides expand and form a gel that creates a feeling of fullness that reduces hunger and prevents overeating.

There is plenty of evidence that shows glucomannan can support weight loss.

However, after evaluating the data provided by numerous clinical trials.

Experts at the European Food Safety Authority (EFSA) have issued strict guidelines for the ingredient’s use and state it will only work for weight loss if its consumed with at least one glass of water, in 1000mg doses, before the three main meals of the day.

The dose provided in each sachet of Slim Me gel is correct, as are the usage guidelines stated by GP Nutrition, so the gel should work well.

The presence of so many B Vitamins deserves a passing nod because they can boost energy levels by helping the body extract calories from food.

However, Iodine and chromium are more interesting inclusions.

Many people are deficient in both these important minerals and that can have a negative effect on the weight.

The thyroid gland uses iodine to create hormones that govern the metabolism.

If the thyroid does not get enough iodine, the metabolism slows, calories are burned more slowly, and the body becomes more prone to weight gain than weight loss.

Chromium regulates insulin levels and prevents the blood sugar crashes that can trigger urges for sweet or carb-rich food.

Green tea is also a good ingredient.

Many studies prove its ability to boost the metabolism and encourage the body to start burning its fat, but the amount provided is too low to provide much benefit.

The same can be said for capsicum extract. It’s a proven fat burner being held back by a low inclusion rate.

Green Coffee Beans

However, green coffee bean extract is included in a more reasonable dose and the chlorogenic acid it provides is known to be a good fat burner so it may help pick up the slack.

Customer Testimonials

We were unable to find a reliable source of Slim Me customer reviews.

A few glowing testimonials are provided on the Slim Me website, but reviews published by manufacturers are often hand-picked and cannot be relied upon to provide an accurate insight into product performance.

Side Effects and Health Considerations

Side effects don’t appear to be an issue, but Slim Me is not a suitable option for women who are pregnant or nursing a child and it should never be given to children under 12-years of age.

People who are under a doctor’s care for an existing medical problem will need to discuss the matter with their doctor prior to commencing supplementation.

Anyone considering using Slim Me alongside medication or other supplements will need to do the same.

Where to Buy Slim Me

It doesn’t appear to be possible to buy Slim Me from any of the obvious choices like pharmacies or Holland & Barrett, but people who wish to do so can buy it in-store or online from Harrods and Selfridges.

The product is also available from selected hotels and health spas.

For most people, the easiest route is likely to be to buy it directly from the manufacturer’s website and we were quite surprised to discover GP Nutrition also appear to be distributing it via Amazon UK.

However, with this product the price appears to be written in stone:

  • 3-Day Supply – £9.99
  • 14-Day Supply – £55
  • 28-Day Supply – £95

It’s possible to make a slight saving by purchasing Slim Me via autoship. This provides a 15% discount, but it also entails a commitment to keep on buying the product for at least three months.


Slim Me is sold with a 30-day money back guarantee.

The Verdict

We really don’t see the sense in selling any form of weight management product in boxes that only contain enough treatments to last for three days.

Even a 14-day supply seems pointless because losing weight is such a long process.

However, the gel sachets provide an effective dose of glucomannan and the usage guidelines ensure customers will be taking it in an effective manner, so the claim that the product reduces hunger holds water.

The claim that Slim Me optimizes the metabolism can also be supported because the iodine content will help prevent the metabolism from being retarded by hormonal deficiencies.

People who use the product alongside diet and exercise should have a better chance of losing weight.

However, the fat burning ability of Slim Me is unlikely to be comparable to other leading diet pills on the market.

The price of Slim Me also works against it and a guarantee that is only good for 30 days seems ridiculous for a product that is so expensive to buy.

A 60-day money back guarantee is the industry norm. Other manufacturers offer this, why can’t GP Nutrition do the same?
