SlimBiome Holland and Barrett

SlimBiome is a new supplement range that is owned and manufactured entirely by UK retailer Holland and Barrett.

Holland and Barrett describe SlimBiome as ‘easy-to-use and affordable weight management’. They claim their ingredients are backed by strong scientific principles and clinical trials to help cut down your weight and nourish your body.

It comes in three options, SlimBiome Original, SlimBiome +Digest (added digestion benefits) and SlimBiome +Thermo (added metabolism benefits).

Although some of the options meet more specific needs, all SlimBiome supplements claim to support weight management and helping to maintain healthy blood sugar.

This is because the main ingredient in SlimBiome’s patented blend is glucomanann, inulin and chromium which can help appetite suppression, gut health and metabolism respectively.

All versions of SlimBiome come with 21 individual satchels and are priced between £18.99 to £19.99.

SlimBiome How to Use

Stir and dissolve one sachet of SlimBiome into 200ml of water and consume in full 30 minutes before meals. Consume SlimBiome immediately once dissolved as liquid will become thicker over time. Take 1 sachet up to 3 times a day. Do not exceed stated dose.

SlimBiome Original Review

This is our overview of the SlimBiome Original, we look at the ingredients, side effects and more.

The main benefits of this supplement is that it can help to make you feel fuller for longer, balance your blood sugar levels and help you lose excess weight.

Here’s what you need to know:

Slim Biome Ingredients

SlimBiome Original Ingredients:

  • SlimBiome (Fructo-oligosaccharide, Glucomannan [1 g], Chromium Picolinate) – 3 g
  • Vitamin C – 12 mg
  • Vitamin B1 – 1.1 mg
  • Vitamin B2 – 1.4 mg
  • Vitamin B6 – 1.4 mg
  • Vitamin B12 – 2.5 µg
  • Chromium – 83 µg
  • Magnesium – 56 mg
  • Zinc – 2.5 mg

Right off the bat, we love the fact that all the dosages are clearly displayed in SlimBiome Original. You know exactly how much of each ingredient you’re getting, which makes it easier to know how effective it will actually be.

The only problem that we have with it is that it doesn’t completely detail the dosages of what’s in their patented formula – we know there’s 1 g of Glucomannan but what about the rest? It’s not the best – but it’s something at least.

So, what do these ingredients do?

SlimBiome Patented Formula – 3 g

There are 3 ingredients in here:

  1. Glucomanannan
  2. Inulin
  3. Chromium

Glucomannan is a fibrous complex which swells in your stomach after being consumed. It as an effective option at promoting appetite suppression.

By swelling in your stomach, Glucomannan fills up the space in your stomach which makes you feel fuller than you actually are. It’s also very low calorie, so you’re taking in less but feel like you’ve eaten more which can help towards weight management and avoid snacking.

Inulin is another fibre, but this is good for digestive health rather than appetite suppression. Inulin passes through your body’s GI tract undigested, and arrives in your colon which allows it to feed that bacteria in your gut and improve your overall digestive health.

Finally, Chromium is a good mineral to improve your body’s metabolism and also help to maintain your body’s blood sugar at a healthy level. This can help you to burn some additional calories.

Vitamin C – 1.1 mg

Vitamin C is essential to your body. It has some high antioxidant properties which can help keep your immune system strong as well as help other areas such as blood flow, and keeping your blood glucose in check.

Vitamin B1, B2, B6 and B12

Vitamin Bs are great for supporting general health in your body. It can help with metabolism and other elements such as cell health, growth of red blood cells, energy, nerve function and more.

It won’t make much difference here in SlimBiome – but it’s good to have in their to support healthy levels of Vitmain B in your system.

Slim Biome Digest Review

SlimBiome +Digest Review

SlimBiome +Digest is the Original formula with a few extra additions. On top of the original formula SlimBiome +Digest also contains Apple Cider Vinegar, Aloe Vera and Liquorice.

Slim Biome Digest Ingredients

SlimBiome +Digest Ingredients:

  • SlimBiome – 3 g
  • Vitamin C – 13 mg
  • Thiamin (Vitamin B1) – 1.2 mg
  • Riboflavin (Vitamin B2) – 1.5 mg
  • Vitamin B6 – 1.5 mg
  • Vitamin B12 – 2.5 µg
  • Chromium – 83 µg
  • Magnesium – 56 mg
  • Zinc – 2.5 mg
  • Apple Cider Vinegar – 110 mg
  • Aloe Vera (200:1) – 105.3 mg
  • Liquorice – 105.3 mg

As you can see, we’ve covered a lot of the ingredients in here already. To save you the rundown of all the ingredients we’ve seen, we’ll give you the write-up of the ingredients which are unique to SlimBiome +Digest.

Apple Cider Vinegar – 110 mg

This ingredient in SlimBiome +Digest may help you to some extent with blood sugar. It has been seen in some cases to help reduce glucose spikes and reducing your appetite when consuming it with meals.

This may help to some extent with weight management, but there’s not much research to show it to actually be effective for this cause.

Aloe Vera (200:1) – 105.3 mg

Aloe Vera is usually used for skin complaints, but it does have some benefits if you supplement it like in SlimBiome +Digest.

Orally ingesting Aloe Vera can help with your intestinal mobility, which can help speed up your body’s digestion and and even help to some extent to alleviate the effects of constipation.

Liquorice – 105.3 mg

Liquorice is a nutrient which is used in various Traditional Chinese Medicine which is claimed to help promote digestive health.

There isn’t much research to support this, but there is plenty of anecdotal evidence to vouch for it. Aside from that there aren’t a lot of other benefits that go along with Liquorice when it comes to weight management and digestion.

Slim Biome Thermo Review

SlimBiome +Thermo Review

SlimBiome +Thermo is the more targeted ‘fat burn’ version of SlimBiome Original. Again, all the same ingredients are in here, with some additional ingredients to help promote overall fat burning.

Slim Biome Thermo Ingredients

Let’s take a look:

  • SlimBiome – 3 g
  • Vitamin C – 13 mg
  • Thiamin (Vitamin B1) – 1.2 mg
  • Riboflavin (Vitamin B2) – 1.5 mg
  • Vitamin B6 – 1.5 mg
  • Vitamin B12 – 2.5 µg
  • Chromium – 83 µg
  • Magnesium – 63 mg
  • Zinc – 2.7 mg
  • Green Tea Extract – 219 mg
  • Guarana Extract Blend – 164 mg
  • Garcinia Cambogia – 109.5 mg

You know the drill – we’re familiar with most of the ingredients in SlimBiome +Thermo, so let’s look at the new guys:

Green Tea Extract – 219 mg

Great fat burner. Green Tea is one of the better natural fat burners on the market.

It contains catechins which are antioxidants which can increase your body’s levels of the fat burning norepinephrine. The more norepinephrine you have in your system, the more support your body has to burn fat.

Not only that Green Tea has some degree of caffeine which can increase your focus, energy and metabolism which can help you burn more calories.

Guarana Extract Blend – 164 mg

This is a herb with a high level of caffeine. Guarana is the nutrient that you commonly find in energy drinks as it has a large amount of caffeine compared with other herbs like tea.

With high levels of caffeine Guarana can help SlimBiome +Thermo to improve focus, energy and metabolism to increase your calorie output to promote fat loss.

SlimBiome Side Effects

It’s unlikely that you will experience any side effects from taking SlimBiome Original, +Digest or +Thermo. It contains a lot of safe natural ingredients which aren’t linked to causing problems when taken in moderation.

The only SlimBiome we suggest that you be cautious with is the +Thermo. The reason being is that it has a higher caffeine content – which may take you off-guard if you are not used to it.

SlimBiome VS Boombod: Which is better?

There is little difference between BoomBod and SlimBiome Original.

Both contain 1 g of Glucomannan, Magnesium, Vitamin C, Vitamin B6, Vitamin B2, Zinc and Chromium.

However, BoomBod also contains Iron – and SlimBiome Original also has Inuliun, B1 and B12.

Weighed up SlimBiome is probably the better deal as the Inulin gives you the additional prebiotic benefits and SlimBiome also has the additional options of having SlimBiome +Digest and SlimBiome +Thermo which can help more with your digestive system and fat loss.

Side by side, we have to give it to Holland and Barrett’s SlimBiome. These are both supplements that you can put in water and drink that offer largely the same thing – but we feel that SlimBiome is slightly more effective.

Slim Biome Reviews

Does SlimBiome Work?

To a degree, SlimBiome Original offers some benefit when it comes to appetite suppression. However, is it the best fat burner out there?

We wouldn’t say so, there are some elements from this fat burner that are missing that we see in many more mainstream fat burners.

For example, Green Coffee Bean is a fantastic fat burner, and it is not present in this supplement. Green Coffee Bean contains chlorogenic acid, which can cut down the glucose in your liver. In doing so, your body has to look for a new energy resource, in doing so it cuts into your fat stores to make it up. Choline is another one that can help metabolism, which isn’t in here – and Turmeric is another great thermogenic that we’re not seeing here.

It does have some merit, but there are plenty of ways that SlimBiome Original could be improved.

What we recommend:
