Product Overview – What Is Natures Burn?

We have seen a lot of chatter about Natures Burn over the last few months, so we thought now was the right time to conduct a comprehensive Natures Burn review. 

Natures Burn is produced by NutriChem Labs. These guys offer a range of sports supplements, including a testosterone booster, a pump enhancer, and a joint-relief supplement; exactly the kinds of products you would expect to see on offer from a relatively new, relatively small manufacturer. 

It’s a bit tricky finding out any detailed information about NutriChem Labs, such as where they are based or who exactly owns the company. That isn’t necessarily a bad thing, but we do prefer to know who it is what we’re buying supplements from. 

That said, the NutriChem Labs website is set up very well. A lot of time and effort clearly goes into it, not to mention into the packaging, which tells us that these guys care about the lifespan of their brand. That’s always a good sign. 

So what about Natures Burn itself?


Natures Burn Fat Burner Review


Natures Burn is sold as a “muscle preserving fat burner”. This is in reference to the “Nutri Burn Amino Blend”; the amino acid blend found in the Natures Burn formula. According to the manufacturers, this blend “contains amino acids that prevent the loss of muscle and aids in the growth of muscle, allowing your body to speed up calorie burning rather than slow it down.”

Not only that, but according to NutriChem Labs, those “amino acids also aid in transport of fat molecules out of the body.”

According to the bottle, the product also helps to boost metabolism, accelerate fat loss, and (interestingly) improve both mood and focus.

Those are some pretty amazing claims to make about an all-natural fat loss supplement. 

If NutriChem Labs can genuinely back up these claims with results, then in Natures Burn they have a pretty remarkable supplement. But that is the key question: can they back up their claims with results?

Does Natures Burn really work? 

Can it preserve muscle while aiding with fat loss?

What about the side effects risk while using Natures Burn? 

Is there a better fat burner on the market?

We’ll answer all of these questions and more in our full Natures Burn review. Continue reading to find out if Natures Burn is really the right product for you. If you have any questions, then please post them in the comments section below. We can usually get back to you within 48 hours. 


Natures Burn Formula Review

The most important thing to look at when deciding whether or not a fat burner is what you’re looking for is the formula. Not the fancy bottle, not the advertisements, and not the “verified customer” reviews on the official website. It is helpful to look at what other people are saying about the product, but the formula is the ultimate deciding factor of a supplement’s quality.

Here is the Natures Burn label:


Natures Burn Formula Review


Proprietary Blends!

The first thing you will no doubt notice about Natures Burn is the proprietary blends. 

We really do have no time at all for proprietary blends on this website. Plenty of manufacturers are able to divulge their entire formula in detail and make a lot of money, so there is no reason every other manufacturer can’t do the same. 


NutriChem Labs Natures Burn proprietary blend


So why do some manufacturers use them?

Proprietary blends are most commonly used to mask the fact that the supplement isn’t worth a ¼ of the price tag. 

So a supplement producer might have a proprietary blend with a total serving size of 1000mg. They can buy an ingredient that is very cheap to purchase in huge amounts, and use that to take up 99% of the formula. A classic example here would be glutamine, which is roughly $20/kg. 

They can then buy small amounts of more expensive (and typically more effective) ingredients to make up the remaining 100mg of the formula. So they could include just 10mg of green coffee bean extract, 10mg of CLA powder, 10mg of green tea extract, 10mg of caffeine anhydrous, and so on.

By listing all of these ingredients together, a manufacturer can create the impression that the ingredients are all dosed fairly equally, when in reality the more expensive ingredients may as well not be there at all. The customer thinks they are getting all of the best fat burning ingredients, when they are really just buying a very over-priced glutamine supplement. 

But we are speaking very generally here. Let’s take a look at the blends found in Natures Burn and see what we can make of them. 


Natures Burn Fat Burning Blend

In this blend we have 1464mg divided among 12 ingredients. if we divide the total serving size equally among the ingredients, we get 122mg per ingredient. Either all of the best ingredients are egregiously under-dosed, or some key ingredients are dosed appropriately while others are missed out completely.

Take glucomannan for example. 

This is one of our favorite fat burning substances available. It helps control appetite and can prevent binge eating by bulking out the food that you eat. It doesn’t prevent any nutrients from being absorbed; it simply makes your meals feel bigger than they are. This helps stop the distracting hunger we all get while dieting.

Yet like every natural fat burner, dose is key. 

The best glucomannan-containing fat burners on the market today can provide as much as 1800mg of glucomannan per serving: that’s more than the total Fat Burning Blend in Natures Burn!


NutriChem Labs Natures Burn Ingredients Glucomannan


Another ingredient that raises questions here is green tea extract.

In our opinion, green tea extract should be in every fat burner that wants to be taken seriously. It contains a catechin called ECGC which has some powerful fat burning properties. Several clinical trials have observed ECGC increasing the rate of fat loss in humans. 

But again, this ingredient is dose sensitive. Too little, and there is almost no point taking any at all. 

Our current top rated fat burner, Instant Knockout, contains 500mg of green tea extract per serving. 

If Natures Burn contained this much, then that would leave less than 1000mg for the remaining 11 ingredients. Even if it were dosed at 300mg (the minimum we’d like to see in a high quality fat burner), then the remaining 1100mg would still not be enough to allocate large enough serving sizes to the best ingredients. 

A blend size of 1464mg is simply not enough to accommodate all of the best fat burning ingredients at the serving sizes they need to be at to really do their thing.

Unproven Ingredients

A final problem with the fat burning blend is the fact that some of the ingredients are still largely unproven.

There is a great deal of hype surrounding the likes of Garcinia Cambogia and Synephrine lately. Plenty of health and fitness blogs write volumes about these ingredients, telling people all about the amazing things they can do for their waistlines. 

However, we try to avoid getting caught up in the hype. We examine ingredients based on their merits as demonstrated in robust, reliable clinical trials using human beings and reasonable doses. 

As far as we are aware, there is no solid evidence that Garcinia Cambogia is reliably able to enhance the rate of fat loss in human beings. There is a lot of insinuation that its ability to make food taste better lends itself to dieting success, but that is just conjecture at this stage. 

Many people believe that Synephrine acts like ephedrine in the body. This may be true, but its effect is so much weaker than ephedrine that the comparison is unwarranted (do not try to use ephedrine to lose weight, it is immensely dangerous to play around with things of that nature). 

Perhaps the best ingredients are all dosed well and the lesser ingredients (Garcinia Cambogia, Synephrine, etc) are all aggressively under-dosed. But if that is the case, then why bother including them at all?


“Muscle Preserving” Amino Acid Blend

NutriChem Labs are definitely right about one thing: amino acids are indeed key to maintaining muscle mass.

Of particular importance are the proteinogenic branched chain amino acids: leucine, isoleucine, and valine. 

Leucine is almost like the growth trigger for muscle cells; if they detect leucine, they start protein synthesis and begin to build muscle mass. 


NutriChem Labs Natures Burn amino blend preserve muscle



Consuming leucine on a regular basis throughout the day is a fantastic way to maximize muscle mass retention while dieting. It is also a good tactic to employ while bulking, or when stepping up your training for a brief period.

Unfortunately, leucine is not a part of the amino blend in Natures Burn. 

The amino acids found in the Natures Burn definitely contribute to maintaining muscle mass, but only in so much as they act as a replacement for food. They tell your body that it is time to use the energy just consumed or store it if it is not needed. They do not have any kind of special anabolism-inducing properties themselves. 

Their ability to preserve muscle mass would therefore also depend upon dosage.

So how much of each amino acid is in Natures Burn? 100mg? 1mg? Your guess is as good as ours!


B Vitamin Complex

It’s always a good idea to include a B Vitamin complex in a fat burner. That’s true regardless of whether the product is supposed to double-up as a pre-workout, a focus-booster, or if it is just a simple diet pill. 

B vitamins are necessary for the proper metabolic functioning. 

Without sufficient levels of B6 or B12, you will not properly be able to get energy from the food that you eat.

When dieting, you are consuming less food than usual, so it is all the more important that you get all the nutrients you can out of every meal. 

Taking a B vitamin complex while dieting can help maintain energy levels and keep you focused all day long, not just in the gym. 

That said, the vitamin complex in Natures Burn is a little weak. Many store-bought B vitamin complexes provide many thousands of times your RDA for B3, B5, B6 and B12. There doesn’t seem to be an upper threshold on B vitamin intake, so lots of over-the-counter supplements provide 4,000% of your RDI and upwards. Some pre-workouts go as high as 6000% of your RDI for B6 (which can produce a tingling sensation).

Natures Burn Side Effects

It is inherently difficult to say whether a supplement will cause side effects when we don’t know the serving sizes of the individual ingredients. 

This is especially true when supplements contain caffeine, as consuming excessive amounts of caffeine can cause some fairly uncomfortable side effects.

Natures Burn doesn’t tell us the individual ingredient serving sizes, and the proprietary blend contains caffeine. This is a problem to consider before placing an order, especially if you are sensitive to stimulants like caffeine. 

Synephrine may also pose a side effect risk, particularly if the dosage is high. As we don’t know how high the dose is in Natures Burn, we can’t say how high the risk of side effects is either. 

Uncertainty isn’t a good thing when discussing safety. Generally speaking, if you can’t tell whether or not something is safe, then you can reasonably call it unsafe until you prove otherwise. 

Consult with your doctor before taking this supplement. It contains indeterminate quantities of substances that you will not be used to consuming on a regular basis. Do not gamble with your health. Even if you think you will be fine using this natural fat burner, your doctor knows your body better than you do. Get their opinion before proceeding.


NutriChem Labs Natures Burn Review Conclusion

The fact that NutriChem Labs decided to lump together 12 ingredients in a 1464mg proprietary blend is the real underlying problem with this fat loss supplement. 

The fact that the blend contains some ingredients which work best when dosed well above 300mg makes this problem worse. That one ingredient works best when dosed above 1464mg really seals the deal for us on this one. 

To make matters worse, some of the ingredients in the “fat burning blend”, such as raspberry ketones and synephrine, seem to be backed up by nothing more than hearsay and hype. To our knowledge there are currently no studies which prove that these substances accelerate fat loss in healthy human beings. 

If you are looking for a supplement to help you start shedding body fat as fast as possible, then you would be better placed buying a product more predictable and more transparent than Natures Burn.
