Full RARI Nutrition Lean Genes Review
Product Overview
We initially first heard of this product by coming across a Lean Genes review on a fitness blog. However, after looking into this fat burner a little more, we realized that the majority of you googling “RARI Nutrition Lean Genes review” are likely doing so after seeing this product on sale on Amazon.
More and more often people are using Amazon to find supplements.
There’s nothing wrong with this of course, but the stated popularity of a product on Amazon can often skew your decisions. That’s why we spend so much time reviewing fat burners.
Lean Genes is a specially formulated fat burner from RARI Nutrition, who are a relatively new sports supplement producer.
They currently offer a creatine supplement, a pre-workout, and a fat burner. At the time of writing, their website states that their apparel is due to be made available in the near future. We do not know if they intend to produce more supplements in the future, or if they intend to keep their range limited to the three product currently on offer.
What we do know is that this company clearly cares about its brand image. The website is pretty sleek, they have a “contact us” section, and most tellingly, you can buy their supplements directly from them.
Some manufacturers choose to only sell their supplements through third party merchants like eBay or Amazon. This is usually a sign that a supplement has very low manufacturing quality, or that it is just a complete scam.
While buying directly from the manufacturer doesn’t necessarily guard against this, it’s definitely a good sign.
So, what does Lean Genes claims to be able to do?
According to RARI, Lean Genes can:
- Increase metabolism
- Suppress appetite
- Produce “maximum” fat loss
- No “shakes” or “jitters”
We see most of these claims on every single fat burner we review.
One claim that stands out slightly is that Lean Genes categorically doesn’t produce any “jitters” or “shakes”. We certainly don’t want either of those, but it’s rare for a fat burner to be so emphatic about this point. This is very interesting, so we’ll examine this closely later on.
Other than that of course, these claimed benefits are same old, same old.
The important question is: is any of it true?
Can Lean Genes really do any of this?
There’s only one way to find out. Let’s take a closer look at the RARI Nutrition Lean Genes formula and see if this supplement is really all that it’s cracked up to be.
Here is our full RARI Nutrition Lean Genes review.
Lean Genes Formula
Before we really start talking about Lean Genes, here’s the product label as seen on the RARI Nutrition website:
Before we start discussing proprietary blends, here is a quick overview of how each ingredient is thought to help with fat loss:
Citrus Aurantium (Bitter Orange)
Lots of properties have been attributed to this ingredient in the last few years, due to the presence of a compound called synephrine. Supplement manufacturers seem to be convinced that synephrine has some incredible fat burning abilities, such as increasing metabolism and decreasing appetite.
However, we haven’t seen a great deal of hard evidence to support these claims.
Garcinia Cambogia
This is another ingredient where there is a lot of talk but very little in the way of hard, scientific evidence to back it up. It is claimed that Garcinia works by suppressing appetite.
However, studies have been conducted on its effect on humans, and no significant appetite suppressing effect has ever (to our knowledge) been observed. Garcinia Cambogia is known to increase satiety in the sense that it makes your meals taste nicer, but that doesn’t mean the same thing as appetite suppression.
Even anecdotal evidence for the efficacy of Garcinia Cambogia is limited. In our experience it seems to work for the minority of people.
GABA (Gamma-Aminobutyric Acid)
GABA is often found in nootropics (brain supplements). This is because it acts on the GABA brain receptor, which is the same pathway through which alcohol works. With that knowledge, you can probably guess what some of the effects of GABA supplementation are; mood elevation, decreased anxiety, and promotion of a general feeling of well-being.
RARI Nutrition claim on their website that GABA has fat burning properties, but we aren’t aware of any. Its presence in a fat burner is therefore a bit puzzling. The only explanation is that it helps stop you getting cranky from hunger while dieting, but that isn’t particularly convincing.

Caffeine Anhydrous
This is a great ingredient. Caffeine helps keep you focused and alert. It can keep you motivated and energized in the gym, even though your diet might otherwise be sapping your energy levels.
Caffeine anhydrous is just a dehydrated form of caffeine; it contains no water molecules, so is more potent than straight caffeine by weight.
Acetyl L-Carnitine
This is another good ingredient, although its effectiveness is highly dependent on dose size.
ALCAR, as this ingredient is usually known, facilitates the transport of fat into your cell mitochondria. This basically means that it makes it easier for your fat to be transported to your body’s engines, where it is burned for energy. It is obvious, then, why you routinely find this compound in fat burners. However, as we have already said, its effectiveness is really dependent on dosage. Anything less than 500mg is really not worth bothering with if you want noticeable results.
Hordenine HCL
We’ll come right out and say it: we’re not huge fans of hordenine.
This is a natural stimulant, yes, but it is routinely used in scammy diet pills, the likes of which you see advertised on TV and then a few months later, they’re gone. It is thought that hordenine is able to boost energy levels and suppress appetite at the same time.
This may be true, but it doesn’t seem to work in a healthy way; certainly not one that is conducive to the lifestyle of an athlete or bodybuilder. It is known to regularly cause shortness of breath, elevated breathing rate, high pulse rate, and headaches.
Acetyl L-Tyrosine
Tyrosine is another compound usually found in natural ‘focus’ supplements, and with good reason.
Tyrosine supports focus and motivation, in large part by supporting the synthesis of neurotransmitters responsible for keeping you motivated and committed.
Like Carnitine, however, Tyrosine’s effectiveness is also massively dose dependent. Below a certain threshold (500mg), its effects will be almost imperceptible, if there are any effects at all.
Vinpocetine
Vinpoectine is found in lots of mood and focus supplements, but every manufacturer seems to offer a unique explanation as to why it is there, and what it really does.
We think its most likely that vinpoectine improves blood flow to the brain without simply raising systemic blood pressure. This is really useful if you need your brain to be in tip-top condition for a prolonged period of time. But is it really necessary in a fat burner? Working out doesn’t require the same kind of short term memory exertion that a college test might, so its inclusion here might be a bit of a mistake.
Theobromine
Theobromine is a natural substance found in cocoa. It has a very similar effect on the body as caffeine, but it is significantly weaker.
It is the presence of theobromine in cocoa which is why so many people get an emotional, almost narcotic response to eating chocolate.
Beyond a weakly simulatory effect, theobromine doesn’t seem to have any significant fat burning properties of its own. It seems strange then to include this stuff in a supplement that already contains caffeine anhydrous; a much more potent stimulant with far more use to us as a fat burner.
Mucuna Pruriens Extract
This is the first time on this website that we have had to discuss mucuna pruriens. It isn’t a typical fat burner or pre-workout ingredient. It is, however, a very common ingredient in natural testosterone boosters and hormonal support supplements for men.
Mucuna Pruriens is a natural substance very high in L-DOPA; a direct precursor to dopamine. The Mucuna Pruriens in Lean Genes is said to be standardized to have a 98% L-DOPA concentration.
Mucuna is also thought to help with fertility problems in men. However, we haven’t done a great deal of digging into these effects as they do not directly concern fitness and athletic performance.
PROPRIETARY BLENDS! – What Is The Big Deal?
As you will have noticed, Lean Genes uses proprietary blends.
If you have read a few articles on this site, then you’ll know how much we loathe proprietary blends.
For starters, the obvious reason why nobody really likes proprietary blends is because they are usually used to disguise how cheap a supplement really is to manufacture.
But this isn’t the only reason why we loathe proprietary blends.
Many manufacturers will lash out at the above claim and say that their customers should trust them, and that they don’t need to know the blend: it just works and that’s enough, so buy it.
We disagree.
In our opinion, whether or not the doses in a supplement are ideal is irrelevant: products that don’t tell us their individual ingredient serving sizes represent worse value for money than products that tell us everything.
This is because part of the value you get out of using fat burners, or any sports supplements for that matter, is the learning experience.
Every time you use a fat burner, you learn a little bit more about what substances work for you, and how you respond to certain dosages of certain ingredients. Perhaps your first stack contained 150mg of caffeine anhydrous, and you never really felt an energy boost. Imagine your next stack contained 400mg, but you experienced annoying side effects. With that information, you know your next stack needs to be somewhere in the region of 250-300mg.
Well, if you use products that only list proprietary blends, you simply can’t do this.
What makes all of this worse is the fact that manufacturers of fat burners have no real need to hide their formulae.
If RARI Nutrition Lean Genes were dosing all of the ingredients ideally, then we would already have a very good idea of what those serving sizes would be. It can’t be, then, that they’ve hit on some “magic” blend that lets them and only them use 10mg of one ingredient but make it feel like 100mg.
If there’s no competitive advantage to using blends, we think manufacturers have no excuse.

RARI Nutrition Lean Genes Review Conclusion – Can This Fat Burner Deliver?
After doing a full review of RARI Nutrition’s Lean Genes fat burner, we are forced to conclude that this fat burner is far from the best fat loss supplement on the market.
To give RARI Nutrition their due, this isn’t one of the scam, under-handed “diet pill” supplements that you see all over the internet these days. RARI clearly want to make a name for themselves, and they take their brand identity quite seriously.
However, that doesn’t necessarily translate to high quality products and god value for money.
Lean Genes contains some good ingredients, but we quite simply have no idea what their dosages are.
As we explained above, this is a serious issue, regardless of what the manufacturer says about “ideal doses” or “rave reviews”.
This is particularly true with Lean Genes, as the product promises “no jitters”, but we have no way of knowing how much caffeine is really in the product. Can they guarantee that there are no jitters because the caffeine content is tiny? Is the caffeine content huge but they have somehow mitigated the side effects? We simply don’t know.
On top of that, each blend contains ingredients that have no real business being in a fat burner. Until we see some hard scientific evidence showing that these substances actually help people lose fat, we can’t just buy into them.
To sum up, we think the vast majority of you would be better off opting for a fat burner that is maybe a little more expensive, but which actually gets the job done.

From what research I have done proprietary blends are mainly to protect a good formula from being stolen. I’ve been using RARI Nutrition products for the past 6 months. Yes, I have heard of some companies using it to hide low amounts of high priced ingredients but if you look at their pre workout, aminos, and other products its all basically clinically dosed or the recommended dose so I trust them in the fact that they’re making Lean Genes with the correct amount. I imagine they’re just trying to protect their formula.
P.s. thanks for the review. This definitely helped me learn about each ingredient.
Hey thanks for commenting. You make some good points JJ.
You are right that many manufacturers do indeed use prop blends to protect the formula, not because they’re being intentionally deceitful. But we think that is just a failing on their part, not something we need to make allowances for. It is not a valid excuse by any means.
For starters, you don’t need to conduct corporate espionage to know that combining certain ingredients enhances fat loss, and the ideal doses of those ingredients are all well-established.
Secondly, plenty of manufacturers divulge their full formula specs on their website and on the bottle, and they don’t have their formulas stolen. Even if they do, they clearly still make a hell of a lot of money. If they can do it, then we expect everybody to do the same. We aren’t in the business of trying to be sympathetic with a manufacturer’s inadequacies, failings, or shortcomings. The fact that some manufacturers feel they can’t risk putting their formula out there while their competitors can is very much their problem. We simply hold everyone to the highest standard around.
We don’t doubt that you trust RARI to dose the ingredients properly. It’s great that you do. But we just don’t see the need for trust to come into it when other manufacturers are confident enough in their ability to make money to put their full formula on their website. We don’t owe RARI anything after all.
We’ll do a full article on the fundamental problems with proprietary blends quite soon.
Thanks again for commenting. We don’t get enough reader interaction on this site so we’re always really happy to hear from people!
