Performance Lab SPORT Fat Burner is a supplement made by well-known supplement manufacturer, Opti-Nutra, and sold via their official website only.

The product is classed as a so-called ‘fat burner’, which describes a specific range of plant-based supplements designed to help support your diet and body goals. They usually include ingredients such as plant extracts, vitamins and minerals.

Product website:

Fat burners have somewhat of a chequered reputation, thanks to some unscrupulous manufacturers who market their supplements as miracle pills or magic solutions.

Of course, nothing is ever that easy! Achieving your dream body is a big commitment that will take time, and no supplement can ever offer a shortcut.

The only thing guaranteed to help you lose fat is sticking to a well-planned diet and exercise regime that allows you to burn off more calories than you ingest. That should be the basis of any weight-loss regime you undertake.

No supplement has ever been proven to help with fat burning; however, assuming you’re already following a strong nutrition and exercise plan, supplements may help to support you on your fitness journey.

In this review, we are going to examine the ingredients, dosages and formula of Performance Lab SPORT Fat Burner to ascertain if it is worth buying and whether it makes our list of the top ‘fat burner’ supplements on sale right now.

Performance Lab SPORT Fat Burner – The Basics

The first thing that we like about Performance Lab’s fat burner is that it doesn’t use proprietary blends, which means that we know exactly what goes into this supplement and in what dosages.

Proprietary blends are the bane of the supplement world, used by many inferior products to hide poor dosages or ineffective ingredients. We like a manufacturer that is willing to stand behind its products and be upfront about what they contain.

We also like the fact that this supplement is more than a run-of-the-mill supplement: it is a carefully thought-out product intended for people doing fasted training. That means people training on an empty stomach and following a restricted nutritional schedule.

It’s a good sign when a supplement honestly stresses the need for a strong diet and exercise routine in order to work.

On its website, Performance Lab describes the product as: ‘Muscle-sparing support for exercise and fasted training.’

Unlike many similar products which only emphasise fat loss, SPORT Fat Burner goes for a double-pronged approach.

Because of this slightly unusual emphasis, it contains more uncommon ingredients than your typical product in this category. More on those shortly.

As we said, this product is only available via the official Performance Lab website and you won’t find it anywhere else online, not even Amazon at this time.

It sounds good to us so far, but let’s have a look at the ingredients and dosages.

The Ingredients

Let’s look at the actual ingredients label as shown on the box of this product:

Performance Lab Sport Fat Burner ingredients

The Performance Lab SPORT Fat Burner ingredients formula

Performance Lab SPORT Fat Burner concentrates on just five ingredients, unlike many other competitor fat burners that are crammed with substances. These are:

• HMB (1000mg) – a known metabolite of the Branched Chain Amino Acid, leucine. Often considered the most important BCAA, leucine is claimed to help support your training goals. HMB is claimed to be significantly stronger than leucine alone.

• Coleus Forskohlii (250mg, as Forslean) – a herb used in traditional Indian medicine. Performance Lab’s website says this herb helps to support the main action of this product.

• Capsimax® Cayenne Pepper (50mg) – a common ingredient in many similar supplements, intended to raise body temperature and encourage thermogenesis.

• BioPerine® Black Pepper extract (2.5mg) – a great addition to the formula and aids the absorption of all other ingredients.

• GTF Chromium (60mcg) – which helps to contribute to the maintenance of normal blood glucose levels and normal macronutrient metabolism.

It’s also worth pointing out the quality of those ingredients. SPORT Fat Burner is a very clean formula, committed to being free of GMO, soy, gluten, synthetic additives and animal products.

It is suitable for vegetarians and vegans and is made in a GMP compliant lab. It also uses Plantcaps® capsules made of fermented tapioca and infused with prebiotics as a delivery mechanism.

Performance Lab recommends taking 2-4 capsules of SPORT Fat Burner 15 minutes before training. It stresses that because you’re in a fasted state, your body should absorb more of the supplement, explaining why they recommend just one large serving a day.

What’s Missing?

Performance Lab SPORT Fat Burner isn’t like many other similar products out there right now. Its intention is help support your goals during fasted training.

For that reason, its ingredients differ from the traditionally popular substances, such as green tea and glucomannan, preferring instead HMB and Coleus Forskohlii.

You could argue that an appetite suppressant would be useful here, of course, to allow you to remain’ fasting’ but that’s potentially picking at straws.

Of course, the one substance deliberately missing in SPORT Fat Burner is caffeine, or any other stimulant. Whether that’s a problem for you or not, will depend on personal preference.

Performance Lab SPORT Fat Burner Reviews

Performance Lab launched in late 2018 and is only sold via the official website. As such, it’s hard to find any customer reviews about its products, as it is not available on the likes of Amazon, for instance.

While it would be nice to see some independent customer reviews, we have found most reviews on health and fitness websites as well as professional review websites to be generally positive. Performance Lab SPORT Fat Burner earns a place in our top five as well.

What About Side Effects?

We would always advise you to do your research before taking any new supplements, and to speak to your doctor first if you have any existing health concerns.

However, being stimulant and caffeine-free – combined with a very clean formula – should ensure that Performance Lab SPORT Fat Burner is free from most side-effects.

You won’t experience the jitters, anxiety and subsequent crash that typically comes with high-stimulant supplements, for instance.

Is This The Best Supplement For Me?

Don’t believe any manufacturer who claims their supplement is a ‘miracle pill’ – no product can help you lose weight unless you follow a successful diet and exercise routine.

If you intend to do that, then a fat burner may just help to push you over the edge, and we like the fact that Performance Lab is honest about the amount of work you’ll need to do to achieve success.

We also like the fact that it rejects proprietary blends and that it seeks to tackle potential muscle loss while following a diet and training in a fasted state.

If you intend to follow fasted training and are looking for a stim-free solution, SPORT Fat Burner may be the ideal supplement for you.

Anything Else To Consider?

Whatever fat burner or supplement you choose, you should take the time to consider the manufacturer behind it and its reputation. Opti-Nutra is behind the Performance Lab range and is known as an ethical and respected supplement manufacturer.

They are the company behind the highly praised Mind Lab Pro nootropic supplement and pride themselves on providing quality vegan-friendly stimulant-free effective supplements.

The Performance Lab range – which comprises supplements for multivitamins, vision, energy, sleep, mind and prebiotics, as well as a SPORT range with pre and post-workouts, BCAAs and a T-Booster – are also designed to work together in synergy.

This means that you can safely choose to stack two or more Performance Lab supplements together, secure in the knowledge that you are not going to overdose on any dangerous ingredients.

Review Conclusion – Final Thoughts

Performance Lab SPORT Fat Burner is a simple product that doesn’t rely on caffeine or stimulants to work.

It has a super-clean formula and is one of the few supplements on the market suitable for vegans.

Overall, we were very impressed with SPORT Fat Burner. It’s a great solution if you want to combine your supplement with fasted exercise, and if you want a stimulant-free option.

Prices begin at £40 per bottle, but there are discounts for multiple bottles and free worldwide shipping on orders over £150.

The price is slightly more than some of its competitors but the saying that you pay for quality would seem to apply here.
