This is why it’s our #1 for women:

Performance Lab SPORT Fat Burner
$50.00 / £40.00 / €45.00
$1.66 a day
Normally, we’d finish an article like this with the best option for men, the best option for women, and move on – but we couldn’t not include this one.
At $50.00 a box, Performance Lab’s SPORT Fat Burner really impressed us, and it’s also cheaper than our other two in this list.
It is the only premium fat burner on the market designed for fasted workouts, and the quality of the ingredients is not to be ignored.
Unlike the other two ingredients in this supplement, it is tailored to help those who train fasted.
Here’s what we like the most about Performance Lab’s Fat Burner:
- Stimulant Free – Zero caffeine in this supplement, there are no chance of jitters or side effects.
- Boost Muscle Mass – Coleus Forskohlii & HMB help maintain and promote muscle mass while fasted.
- 100% Vegan – Capsules and ingredients are all safe for vegetarians and vegans.
- Money Back Guarantee – Result in 30 days or your money back.
- Discounts on Multi-Box orders – Free shipping and money off with bigger orders.
- Highest Quality Ingredients – All study-backed and made to the highest possible standard.
It’s easily the cleanest supplement in this list. Performance Lab products are vegan, soy-free, caffeine-free, non-gmo, gluten-free and allergen free. They’re also certified halal and kosher friendly.
Things to consider before purchasing:
- You should be following intermittent fasting – This supplement works best when taken before a fasted workout.
- Can only be bought off Performance Lab site – You can only get this supplement from the official site. (PerformanceLab.com)
This is the cleanest fat burner that we have on our list, and the best option if you’re someone who prefers to fast throughout most of the day.
Again, like all the supplements in this list, Performance Lab’s Fat Burner comes with a money-back guarantee. If you’re not feeling it after 30 days, you can send it back for a full refund.

How did we decide these fat burners?
There was a lot research that was performed when it came to deciding these fat burners. A lot of it was consulting studies, however, there’s much more to it than that.
Generally, you want to be considering three main areas when it comes to a supplement:
- The Ingredients – and if they work.
- The Servings – if there’s enough a day.
- The Manufacturer – and if they care about the customer.
For the rest of this guide, we’re going to focus on these areas and what you should look for in them to get to know if a supplement is right for you.
The Ingredients: What we look for
In our opinion, the ingredients are the most important part of a fat burner. It is the thing that matters most in any supplement like this.
When looking at a fat burner’s ingredients they should always be:
- Open about their dosage
- Backed by studies
- Not linked to side effects
Here’s a little more about what we mean…
Open about their dosages / No Proprietary Blends
One of the biggest problems in the supplements industry at the moment are proprietary blends. This is when a supplement manufacturer chooses to hide the individual dosages of the ingredients used in their product.
Instead, all the ingredients are displayed under one, or several larger dosages.
Take a look at this example:
See in the pink box? None of the dosages here are revealed. This means you don’t know what it is that you’re actually taking.
This could mean several things:
- It’s under-dosed where it counts – The manufacturer doesn’t want you to know they cheaped out on the more expensive ingredients.
- It’s over-dosed in dangerous areas – The ingredients may be balanced in a way that may cause side effects, but the manufacturer doesn’t want that to put you off buying.
- It changes constantly – The manufacturer may keep changing dosages depending on what they can get cheapest at the time of manufacturing.
The bottom line is that this lack of transparency is unacceptable. Without knowing the dosages, you don’t know what you’re getting and this could cause you problems if you’re not careful
Instant Knockout, LeanBean and Performance Lab SPORT Fat Burner all have 100% transparent ingredient labels. You know exactly what you’re getting with each one, and how much.
Backed By Studies
This is another thing that we look for analyzing supplement ingredients – although it should be the most obvious one.
Whenever you come across ingredients in a fat burner, or any supplement, you should research the ingredients to make sure that they have the studies to support the claims.
There are plenty of resources out there that compile studies on natural nutrients and their effect on your health.
Some of our favorites that we tend to look out for include:
- Green Tea – Thermogenic fat burner that also boosts focus. (Found in both Instant Knockout and LeanBean)
- Glucomannan – Fibrous complex that suppresses appetite and regulates cholesterol. (Also found in Instant Knockout and LeanBean)
- Cayenne Pepper – Thermogenic fat burner that also has merit as an appetite suppressant. (Found in Instant Knockout, LeanBean and Performance Lab SPORT Fat Burner)
These are just some of the ingredients to look for to give you an idea of what we look out for.
No Side Effects
Another factor that you want to ensure is that the ingredients that you’re looking at do not have links to any side effects.
To find this out you can look to personal reports of people who have had bad experiences with the nutrient online, or studies where the participants have reported some kind of discomfort from supplementing these nutrients.
Some of the more potent ingredients to look out for include:
- Synephrine (aka Bitter Orange Extract)
- Too Much Caffeine (400mg or higher)
There are more out there, always do your research first. It also helps if the supplement is manufactured in a safe environment. It’s a very good sign if they’re manufactured in somewhere like the USA or UK in a cGMP (Current Goods Manufacturing Process) and FDA approved facility.
The Servings: What works best?
Although ingredients are important, the servings also matter too. How often you take a fat burner throughout the can determine how effective it is.
A good example of this would both be Instant Knockout and LeanBean. Each of these supplements offer 4 servings a day. This is good for fat loss as it constantly supplies your body with the nutrients it needs to keep you burning fat for as long as possible throughout the day.
Performance Lab SPORT Fat Burner on the other hand is only for use before a fasted workout – this helps you get the most out of your training, and burn the most amount of fat during a fast, but also preserves muscle mass.
How your fat burner directs you take it matters.
The Manufacturer: Do they care about you, the customer?
Good looking ingredients and servings are one thing, but having the manufacturer respect you is another.
The supplement industry is huge now, a lot of companies appear to be into it for the money, not for the power of their product.
You need to find a manufacturer that cares about their product and your experience using it. This is a good sign that you’re going to get good results from taking it.
So what should you be looking out for?
Money Back Guarantees
This is a huge sign that your manufacturer believes in what they’re selling to you. If they’re offering a full refund if you don’t see the results you’re looking for this tells you two things:
- They don’t get a lot of refunds – Which is a great sign that the product works.
- They care about your results – They think their product is so good that they take all the risk.
Not a lot of companies offer this – mainly because they want to take the money and run. They’re in it for the long-haul, they know their product works and they want you to get the best out of them.
Instant Knockout, LeanBean and Performance Lab all offer money back guarantees. Instant Knockout and LeanBean ask that you use it for 3 months first, if you don’t see results you can send it back. Performance Lab take that one step further and say if you’re not satisfied by the end of the first 30 days you can send it back.
These are the kind of companies that we’re interested in.
This is another good signal that the manufacturer takes pride in what they’re selling. If you see a lot of positive reviews online about a supplement, it has to be good.
Instant Knockout and LeanBean both have some incredible before and after shots which really show just how effective both these supplements are – and that includes me.
Here’s my results from taking Instant Knockout for 3 months:
You can read my full experience and results from using Instant Knockout over on my review here.
Now here’s Vicky, who took a course of LeanBean:
Again, fantastic results. You can see more of these in our LeanBean review here.
