NutraOne Shred One Review


  • Indole-3-Carbinol might promote fat loss in men by helping to reduce estrogen levels
  • Dandelion Leaf is a diuretic and can reduce water weight (but doesn’t necessarily promote fat loss)
  • Resveratrol may improve general health


  • Shred One no longer seems to be available for purchase
  • No tried-and-tested thermogenics such as cayenne pepper extract (capsaicin)
  • Dandelion Leaf can cause excessive dehydration if not monitored due to being a diuretic, in our honest opinion

About The Product: NutraOne Shred One

Shred One is a fat burner supplement made by NutraOne.

*UPDATE* As of now, this is no longer for sale. So, we can’t determine what price you may buy this for – you might have some luck on Ebay or Amazon should you really want to try it.

This fat burner seems to be popular as we had some of our readers requesting this review. And we always give the people what they want! – if this was you, you can thank us in the comments section if you like…

Anyway, we’ll analyze NutraOne Shred One’s supplement facts label for you in the next section. This will allow you to see how safe and effective this fat burner is compared to others on the market.

But first, we’ll tell you more about the company behind Shred One…

Who is NutraOne?

NutraOne is a supplements company that claims to put the customer first on their website.

There wasn’t a great deal of information on their ‘Our Company’ page, which isn’t an issue. But we were glad to learn that all of their products are made in cGMP certified facilities – you should check that every supplement you take is created to the same manufacturing quality as this.

Anyway, you’re here to learn more about NutraOne Shred One. So, let’s see which ingredients have been added to its formula in the section below…

NutraOne Shred One Ingredients Explained

In terms of supplement facts label, we’re glad to see that none of this fat burner’s ingredients have been hidden in any proprietary blends. This means that you can clearly see the dosages of each nutrient in NutraOne Shred One’s formula, which is what we always want to see.

However, we from first glance, our honest opinion is that this fat burner is lacking thermogenic nutrients; we always want to see at least 1 thermogenic in every fat burner so that you experience an increase in metabolic rate. Ingredients such as Cayenne Pepper Extract (capsaicin) are thermogenics if you are unsure.

The good news, though, is that Indole-3-Carbinol has shown to help reduce estrogen levels. This, in turn, can lead to fat loss.

We’ll expand on all of this by taking you through each ingredient in NutraOne Shred One. By the end of this review, you’ll have a good idea of how safe and effective this fat burner really is.

NutraOne Shred One’s Supplement Facts Label.

Here’s Everything You Need To Know:

White Button Mushroom Extract

We’re a bit confused about why this is included in a fat burner. In fact, if you look at the first few ingredients in NutraOne Shred One, it appears to be more of an aromatase inhibitor (AI) than a fat burner supplement.

Anyway, you’ve now probably guessed that White Button Mushroom Extract can help inhibit aromatase activity. You can see the study that shows this here:

Ultimately, a decrease in estrogen levels can lead to fat loss. But in our experience with fat burner supplements, we’ve had more luck with the ones that contain thermogenics or nutrients that help preserve muscle mass while cutting fat.

However, we will suggest that NutraOne Shred One may be beneficial for those looking to inhibit aromatase and are concerned about estrogen levels for any reason.

DIM & Indole-3-Carbinol

We’ll be honest. We’ve put these 2 ingredients together to save time, but also because they offer the same benefit – they both act as aromatase inhibitors, meaning they can keep your estrogen levels in check.

Ultimately, while 1 AI might benefit you in a fat burner, we don’t believe that there’s any need for 3 in 1 product; we would have much preferred to see a thermogenic such as Cayenne Pepper Extract here instead.

Buchu Leaf 

In our honest opinion, Buchu Leaf seems to be one of those ingredients that were once praised by the media as some sort of ‘wonder herb’. But studies didn’t suggest that it was actually capable of delivering reliable results.

So what is it? Well, it was once used to treat inflammations, as well as kidney and urinary tract infections in traditional medicine.

As we mentioned, it simply hasn’t produced enough reliable results in clinical studies to be considered as a reliable addition to NutraOne Shred One here. But we do praise NutraOne for adding some unique ingredients that aren’t commonly seen in other fat burners.

Dandelion Leaf 

We have very mixed opinions about Dandelion Leaf.

Basically, this ingredient is a diuretic, meaning it can help to reduce water weight (by encouraging your body to pass more urine and hold less water). This can be good for those needing to lose weight very quickly. Eg. Boxers or MMA fighters, or bodybuilders looking to step on stage.

However, diuretics can be potentially harmful when taken without really knowing. So, we always encourage companies to clearly state that their products contain diuretics when adding them.

The other big problem is that water weight isn’t fat loss. So, while you will be lighter on the scales, you won’t have necessarily lost body fat – just water weight.

As a result, we personally don’t always agree with Dandelion Leaf being included in fat burners. They can fool those that don’t realize they are just losing water weight. But saying that, diuretics are useful for those that know exactly what they do and are looking for very rapid weight loss (not fat loss, though).


Juniper Berry Extract

You might have seen Juniper Berries in your Gin & Tonic drinks on a night out…

But you may not have know that they contain antioxidants, meaning they can improve your general health and strengthen your immune system.

One study has shown that Juniper Berry Extract can help lower blood sugar, which can help promote fat loss. However, this study was conducted on rats, not humans, and there haven’t been any other reliable studies that show it can help you lose fat.

As a result, unfortunately, we have to consider Juniper Berry Extract as an unreliable fat burning ingredient. That being said, we do believe that it can deliver benefits due to containing antioxidants.

Uva Ursi 

Uva Ursi is an interesting addition to NutraOne Shred One as we’ve not really seen it in any other fat burner. So we do like that this company have tried new things here.

The main benefit of Uva Ursi is that it contains hydroquinone, which the liver can prepare for waste disposal. This results in Uva Ursi being able to help prevent urinary tract infections.

However, in terms of fat loss, there haven’t been enough convincing studies for it to be a viable addition to NutraOne Shred One (in our honest opinion).


In case you’re wondering, this is a flavone that is naturally found in plants such as the Turnera Diffusa. The main thing to note is that Acacetin is another ingredient in NutraOne ShredOne that is believed to be an aromatase inhibitor.

So, while it might promote fat loss by reducing estrogen levels, it’s also not necessary in this fat burner at this point as it already contains 3 other AIs.

Androst 3 5-dien-7 17-dione

A general rule that we would go by is this; if an ingredient sounds ‘chemically’ then it probably isn’t the best. Of course, this is just our honest opinion so make of this what you will – we always prefer 100% natural ingredients.

One thing to note about this ingredient is that the FDA has not approved of it. You can see that article here.

Anyway, long story short, this is another aromatase inhibitor. So, NutraOne Shred One has really gone with the ‘lower your estrogen’ angle here, instead of the more common thermogenic route (which we believe is more effective in our honest opinion).


Resveratrol is the polyphenol found in red wine that is believed to prolong your lifespan. You’ve probably heard rumors that 1 glass of wine daily can be beneficial for this reason.

As good as that sounds, there aren’t enough reliable studies to back this belief up. So for now, we wouldn’t advise that you drink too much red wine…

However, some good news is that studies suggest it can be beneficial for your general health. The bad news is that it probably won’t help you lose fat.

 NutraOne Shred One Side Effects

In terms of individual ingredients, there isn’t anything that sticks out as a red flag for the most part. Well, in fairness, the Androst 3 5-dien-7 17-dione has been warned against by the FDA so we would personally avoid this.

Also, there are many aromatase inhibitors in this fat burner; taking this many might cause some serious damage – just google ‘dangers of aromatase inhibitors’ and you’ll see what we mean…

One positive is that there isn’t an overload of caffeine like there is in many other fat burners we’ve reviewed. But there is also a lack of thermogenic and muscle preserving nutrients in NutraOne Shred One too.

Here are the potential side effects from taking NutraOne Shred One: 

  • Weakened bones (aromatase inhibitors)
  • Cardiovascular health issues (aromatase inhibitors)

NutraOne Shred One Review Conclusion

We can see what NutraOne has tried to achieve with Shred One here; it’s packed with aromatase inhibitors that can reduce estrogen levels, which can lead to fat loss.

However, in our honest opinion, the best fat burners contain thermogenics (such as Cayenne Pepper Extract) that can boost your metabolic rate. Not forgetting the ingredients that can preserve muscle mass like HMB too.

In conclusion, while this isn’t a bad product for what it aims to do (reduce your estrogen levels), it isn’t exactly what most people are looking for in a fat burner. We truly believe that you’ll see better results by consuming thermogenics, but of course, this is just our honest opinion.
