Review Overview – What does SirenLabs Slimify do?

Made by Siren Labs, this is an all natural fat burner that is claimed to promote:

  • Energy
  • Metabolism
  • Appetite Suppression
  • Fat Loss


But how well does it work?

In this review, we looks closer at Slimify to see how effective it really is.

This is what you need to know:

How are the servings?


With only 1 serving a day, this isn’t your best option for fat loss.

Think about it. Your body can only absorb so much at a time. A lot of the supplement will be wasted and the effects will only last for a few hours.

For the best results you need constant servings throughout the day.

This makes sure your body is constantly topped up with the nutrients you need,

and that your body is constantly burning fat.

It’s a shame Siren Labs didn’t spread these servings out more.

What about the ingredients in Slimify?

Not that great.

A lot of the ingredients in this product aren’t that effect when it comes to causing fat loss.

Not only that, some have even been banned in the EU as ‘novel foods’.

This means we have no idea what the long term effects of these nutrients are, and there is a belief that may cause side effects.

Here’s what you need to know:siren-labs-slimify-side-effects

Vitamin D3

One of the best natural vitamins – although it downs really promote fat loss.

D3 helps to boost immunity and several other essential functions in your body.

It’s good for overall health – but won’t help you cut down.

Garcinia Cambogia

A poor natural fat burner.

Although thought to help promote appetite suppressant, studies have shown that it isn’t actually that effective.


May help promote fat loss – but there’s not a lot evidence.

Studies have shown that Chitosan doesn’t have any real evidence for fat loss.

It was seen to have very minimal effect (0.5kg/1.1lbs fat loss) over the period of 6 months.

It’s barely going to have an impact.

African Mango

Also known as Irvinia Gabonensis – this is a poor fat burner.

Studies have shown that this nutrient has been seen to have very unreliable results when it comes to fat loss.

It barely has an impact, but not only that – Irvinia Gabonensis has classed as a banned supplement in the EU. It’s classed as a novel food.

A novel food means that this nutrient was banned because there are no long term studies into the side effects of this nutrient.

More research is needed on this nutrient.


Another poor addition, another banned EU ‘Novel Food’.

Although aggressively marketed as a fat burner – studies have shown that this nutrient has no real impact on fat loss.

Not only that, there has been no long term research into this nutrient and whether it my cause any problems in the future.

It’s worth avoiding.

Green Tea

One of the best thermogenics.

Green Tea contains catechins which have been seen to promote norepinephrine – the fat burning hormone.

This helps you to burn more fat and calories – and you also get an energy boost from the caffeine.sirenlabs-slimify-results

Ingredients Bottom Line:

On the whole, this isn’t the best fat burning nutrient profile out there.

There’s only one good ingredient in this profile – the green tea.

The rest of the ingredients have barely any impact on fat loss, some are even banned in certain countries.

There’s even a lack of core nutrients like energy boosters and appetite suppressants – Green Coffee Bean, caffeine, glucomannan, cayenne pepper and more would all help out Slimify.

Side Effects

There are no side effects reported with this fat burner as of yet.

However, African Mango and Raspberry Ketones have been banned because there may be some long term effects.

More research needs to be done – be careful with this product.

Is there anything better than this fat burner?
