Lean Genes Fat Incinerator is a health supplement made by a company called RARI Nutrition. It’s been designed to help support your goals with its blend of natural ingredients.

As yo may have guessed from the name, Lean Genes is a product which has been designed to help support you on your journey.

In this review article, we’re going to take a close look at this supplement by examining the ingredients, reading the customer reviews and seeing where it stands in comparison to the other products out there at the moment.

So let’s kick off our Lean Genes review by starting with the basic information.

What does Lean Genes Fat Incinerator do?

As you’ve probably already guessed, Lean Genes Fat Incinerator fits into the wider category of supplements known as so-called ‘fat burners’.

Before we get started, it’s important to realise that most of the supplements in this category, including the one featured on this page, have not been proven to help with fat loss and fat burning.

They are supplements designed to support your goals and that usually contain a number of plant extracts and other ingredients such as vitamins and minerals.

Fat burners usually work in multiple ways to help support your goals.

So, with all of that out of the way, let’s take a close look at the ingredients in Lean Genes.

What you need to know about the ingredients

Having had a quick glance at the label, we found some good ingredients on the list.

However, we were disappointed to see that Lean Genes contains a proprietary blend. This is when the manufacturer has hidden the dosages of the individual ingredients within a total ‘blend’.

We don’t like this because it makes it difficult to assess the quality of the product.

• Caffeine Anhydrous – It was good to see this ingredient on the list because it’s one of our favourite ingredients. You’ll no doubt have already come across it before when doing some of your own research into the top products in this category.

• Citrus Aurantium (bitter orange) – This is an interesting addition to the ingredients list. We’ve started to come across this ingredient more and more often, although we don’t consider it to be one of the top substances. We’re not huge fans of it if we’re honest, and we are not totally convinced about its safety profile.

• Vitamins B6 and B12 – It was great to find these important B vitamins on the label of Lean Genes. We always like to see B Vitamins used in supplements like this, and especially B6 and B12. In case you didn’t know, Vitamins B6 and B12 are two essential vitamins which can help with the reduction of tiredness and fatigue.

• Acetyl L-Carnitine – Again, this is not an ingredient we’ve come across too often in supplements like this before. We have seen it included in a lot of the best pre workout supplements, but not so much in other categories. It’s not a terrible inclusion, but it’s not the worst either.

The other ingredients in Lean Genes are listed below. As we mentioned above, we’re not too happy about finding proprietary blends on the label.


What’s missing?

While there were a few good things on the ingredients label in Lean Genes, there were also quite a lot of substances missing in our opinion.

This means that we don’t classify Lean Genes as one of the very best supplements out there at the moment.

Firstly, there was no Glucomannan on the label. This is one of our favourite ingredients. It’s a dietary fiber which comes from the root of the Konjac plant and is usually added to the top products in this category.

It was also a shame not to find Green Coffee Bean Extract on the label. This is another one of our favorite ingredients but we found it was only generally included in premium supplements.

There were also a few other things missing such as Green Tea Extract and Chromium. We consider both of these to be important as well.

Chromium, in particular, contributes to normal macronutrient metabolism as well as the maintenance of normal blood glucose concentrations.

Are there any side effects?

These kinds of supplements are usually pretty safe because they contain natural ingredients.

That being said, it’s always a good idea to carefully check the label to make sure that you’re not allergic to any of the ingredients.

There are two things to be wary of in this supplement, in our opinion. Firstly, the caffeine content is quite high, so it’s a good idea not to take this supplement too close to bedtime because it could affect your sleep.

Secondly, as we mentioned above, we’ve read about bitter orange causing problems for some people. Again, we’d recommend doing some more research into this.

As ever, we do recommend speaking to your doctor before thinking about trying any new supplement for the first time.

How to take Lean Genes Fat Incinerator

Each bottle of Lean Genes Fat Incinerator contains 60 vegetarian capsules.

That means that if you stick to the maximum daily dosage of two capsules, one bottle will last you for 30 days.

The label says that you should take one capsule a day with a meal for three days to assess your tolerance.

After three days, you can increase to two capsules (1 full serving) per day. Servings should always be taken with a meal.

The label says that to get the best results, use it for 60 days in combination with diet and exercise.

As mentioned above, we’d recommend not taking this supplement too close to bedtime because the caffeine could mess with your sleep.

What are customers saying?

We found a lot of reviews of Lean Genes on sites like Amazon and others.

One customer said that this was the only brand of supplement that did not give them the ‘jitters’.

Someone else said that they had only been taking it a couple of days but they already were feeling the benefits.

However, one user revealed that didn’t notice any results while taking this supplement.

Someone else said that they took it daily for 30 days and didn’t see any changes at all.

Is this the best supplement?

Not in our opinion. Although there are some good things about Lean Genes, the use of proprietary blends and some missing key ingredients mean that we don’t class it as one of the best products around at the moment.

We recently selected our top favorite based on the ingredients and customer feedback. Click the link below to see the list.

Anything else to consider?

As we always say, these kinds of supplements will work best when they are combined with a healthy diet and regular exercise.

You shouldn’t expect a supplement to do all of the hard work for you.

However, a good supplement can help to support you on your journey as you take responsibility for your results.

Review conclusion – our final thoughts

So, is Lean Genes a supplement you should consider taking if you’re looking to get into shape? Here are our thoughts in a nutshell:

• Contains caffeine and B Vitamins
• Solid reviews

• Uses a proprietary blend
• Bitter orange is not a good ingredient

So there we have it, our full review of Lean Genes Fat Incinerator. We’ve been through all of the ingredients, discussed the dosage and looked at the pros and cons of the supplement.

Overall, we think that it’s an OK product, but we definitely think that there are some better products on sale at the moment.
