Iso Tone looks like a complete rip-off to us. It is a proprietary blend with some pretty obvious filler ingredients in there. In our opinion, it is highly likely that Iso Tone is just 90% Sesame Seed Oil. Why else would ANS have included this ingredient; sesame seed oil might make your stir-fries taste better, but it doesn’t have any effect on body composition at all. CLA is a weak fat burner, so at best you’re going to get mediocre results. Not a good supplement at all.
Our Iso Tone Review
Iso Tone is a fat burner made by Advanced Nutrition Systems and distributed by GNC. We can’t find an independent website for ANS, so we think it’s safe to assume that Iso Tone is sold exclusively through GNC. Iso Tone might even be a GNC product; they often bring out products disguised as independent brands to test market trends.
So what does Iso Tone claim to do exactly?
How is it different to any other fat burner on the market right now?
According to the bottle, Iso Tone works along three distinct pathways:
- Tone – probably referring to muscle “tone”
- Metabolize – we assume this means Iso Tone increases metabolic rate
- Tighten – this is a strange one possibly referring to appetite
If you read the GNC product description, it states that Iso Tone can “assist with body-fat reduction, toning and tightening throughout the midsection”.
This is EXTREMELY MISLEADING.
Supplements cannot “tighten” your muscles. Nor can they “tone” them. Muscle “tone” as the word is commonly used is a function of muscle density and body fat – if you have dense muscles and you have low body fat, your muscles will appear “toned”.
This is why the whole “high reps for tone” thing is utter nonsense.
It’s a shame to see a fat burner employing these tricks to try to make sales. After all, we don’t want to believe that the manufacturer actually buys into the idea of a supplement being able to “tone” your muscles.
But anyway, let’s get into it.
Does Iso Tone actually work?
Is it safe? Will it cause side effects?
How does it compare to the best fat burners on the market right now?

ANS Iso Tone Ingredients
Let’s take a look at the Advanced Nutrition Systems Iso Tone formula:
Honestly, this looks like a terrible fat burner.
Those of you who have read a couple of our reviews already will know that we hate proprietary blends. They are always a complete rip-off. There is no legitimate reason to use them; they’re either used to scam customers or because the manufacturer doesn’t understand the market.
All proprietary blends are terrible and to be avoided.
But the Iso Tone formula in particular has some serious flaws.
It is composed entirely of various vegetable oils. Some of these vegetable oils contain compounds that are thought to promote fat loss (although they aren’t particularly powerful). Some of them have absolutely no effect on fat loss whatsoever.
We have no idea how much of any of these vegetable oils we get per serving.
The Iso Tone formula could be mostly high-CLA Safflower Oil Extract, or it could be almost entirely Sesame Seed Oil.
Sesame Seed Oil does not contain anything which benefits someone trying to lose fat. It is just a high-fat, extremely calorific vegetable oil. Consuming sesame seed oil will not help you lose body fat any faster. It will not help you perform better in the gym. It will not help suppress appetite.
And for all we know, Iso Tone could be 95% Sesame Seed Oil.
We strongly recommend that you opt for a more transparent, focused, powerful fat burner. Proprietary blends are always total scams. Let us explain why.
Main Weakness – Proprietary Blend
We loathe proprietary blends. They are always a bad option. They are explicitly designed to rip customers off.
Manufacturers usually claim that they need to use proprietary blends to protect their intellectual property. They claim that they poured years of research into their formulas and now they need to prevent anybody else from just ripping it off.
The problem with this line is that it doesn’t play out in reality.
Formula theft does not happen.
Nobody ‘steals’ another product’s formula.
There would be no point in doing so. The ingredients used in fat burners are typically well-understood; this is true with Iso Tone too.
There’s nothing special about ANS Iso Tone’s ingredients; there is no secret dose of CLA or Fish Oil that will bring about dramatic reductions in adipose tissue. We know how CLA should be dosed and we now how it works.
There is nothing in this formula that might be revolutionary. There isn’t anything that a competitor would benefit from ‘stealing’.
Iso Tone really has nothing to hide.
So why have they used a proprietary blend?
The reason is the same as always – to rip you off!
Proprietary blends allow manufacturers to stuff their formulas full of the cheapest, weakest, least effective ingredients and to cut back on the expensive, effective substances.
They can choose a benign, totally useless ingredient that is incredibly cheap to buy in large amounts and make it 95% of their formula. They then only need to spend money on small amounts of more effective ingredients.
The result is a very cheap formula that appears more expensive on paper.
Profit margins are great for the manufacturer, but you end up paying a premium price for a low-grade dud of a supplement.
We’re sure there are a few instances in which manufacturers do actually believe that they need a prop blend to protect their formulas.
But we don’t care what their reasons are – we inherently value transparency, so we’ll always go for a supplement that displays each ingredient’s serving size clearly on the label.
All of the best-selling supplements on the market today display their formulas in full; doses included. Why would we opt for anything less than complete transparency?!
Major Weakness – Obvious Filler Ingredients
As explained above, proprietary blends are primarily used so that manufacturers can stuff their formulas full of cheap, ineffective ingredients. This allows them to cut right back on the more expensive fat burners without the customer ever finding out.
You can usually spot a ‘filler’ ingredient from a mile away – they’re cheap, usually completely benign and side effect-free, and can be consumed in large amounts.
The Iso Tone formula contains one obvious filler ingredient – Sesame Seed Oil.
This is the stuff you can buy form any supermarket in the UK. It costs about £10 for a litre, and that’s if you’re buying the good stuff. Got to a Chinese supermarket and you can get a bulk bottle for very cheap.
Sesame Seed Oil does not have any fat burning properties. No studies have eve established a connection between sesame seed oil consumption and reduced body fat, improved athletic performance, reduced appetite, nor anything that might beneficial in a fat burner.
So you have to ask yourself why ANS Iso Tone contains this ingredient.
We believe it is here purely to act as a ‘filler’. We think it is highly likely that a lot of the Iso Tone formula is just Sesame Seed Oil.
There is – after all – no other reason for it to be in Iso Tone! Sesame Seed Oil is not a fat burner!
Major Weakness – CLA Not A Powerful Fat Burner
The final weakness we’d like to talk about is the fact that it seems to be mostly powered by CLA.
The first ingredient listed in the proprietary blend is Safflower Oil which has been enriched to 80% Conjugated Linoleic Acid (CLA). We aren’t told how much of this stuff we get of course, so the percentage of CLA is kind of meaningless.
The other ingredients aren’t thought to be fat burners. For instance, Fish Oil might be good for your general health and cardiovascular function, but it doesn’t stimulate fat loss.
So Iso Tone is pretty much a CLA supplement with some supporting ingredients thrown in. This is the best case scenario anyway; we think it is more likely to be a sesame seed oil supplement!
The problem with even this best case scenario is that CLA is not a very potent fat burner.
Several good quality clinical trials have looked at CLA supplementation and its effect on fat loss. So far, it has produced just modest reductions in fat mass relative to control.
For example, in this paper researchers highlight a number of different clinical trials looking at CLA and its effect on everything from waist circumference to blood lipid profiles. As you’ll see if you read the paper, CLA is extremely unreliable; it routinely produces inconsistent, even contradictory results.
The researchers ultimately found CLA to be an ineffective fat burner: “Finally, a meta-analysis that included 7 clinical assays in the final analysis for the purpose of evaluating the use of CLA during a long time did not show significant results to support changes in the body composition when using CLA for a longer period”.
Other trials which are routinely cited in support of CLA are – on closer inspection – far from convincing. One paper which is regularly quote to support the use of CLA found that people using it lost 0.024kg more than the control group (source). Hardly nature’s answer to Trenbolone!
So even if Iso Tone contains a large dose of CLA – which we doubt – the results are always going to be limited.
We think you can do an awful lot better than Iso Tone. The best case scenario is that it contains a lot of an unreliable, inconsistent fat burner.
Iso Tone Side Effects – What Are The Risks?
It’s always hard to talk about health risks and side effects with any accuracy when you’re dealing with a proprietary blend.
But on the whole, we think Iso Tone looks perfectly safe for the vast majority of you. The ingredients in Iso Tone are not known to cause serious side effects; certainly not at these possible doses (given the total blend size).
Iso Tone only contains high-CLA Safflower Oil, Borage Oil, Fish Oil, Flax Oil, and Sesame Seed Oil.
These substances have all been studied extensively in independent clinical trials published in peer-reviewed journals. They are not thought to be dangerous; they have each been deemed safe for general human consumption.
We’ve never even seen reports of mild side effects from these ingredients – not in the clinical literature anyway.
So while we doubt many of you will experience significant results from Iso Tone, we also doubt that you’ll experience any side effects.
Of course, Iso Tone contains potentially large quantities of oils you wont be used to taking on a regular basis. You therefore might experience some digestive discomfort, bloating, indigestion, etc.
If you experience any side effects whatsoever while using Iso Tone, stop using it and seek medical attention immediately. Contact Advanced Nutrition Systems if you have any concerns about Iso Tone.
Please remember the following facts while reading our fat burner reviews:
- This is not medical advice
- We are not doctors
You must do your own research and talk to a qualified doctor if you have any concerns whatsoever. If you think you have any pre-existing conditions which might be relevant to the safety of Iso Tone, talk to your GP. Fat Burners are serious supplements designed for athletes; they are not quick cures for obesity.
Pricing – How Much Is ANS Iso Tone?
Possibly the biggest problem with ANS Iso Tone is the price.
We actually can’t believe how much these guys are asking for this fat burner.
Advanced Nutrition Systems Iso Tone costs $44.99 per bottle. That comes to about £35 (at the time of writing).
For a product that is at best a lot of CLA and at worst a lot of Sesame Seed Oil, $44.99 is far too expensive.
Honestly, we think any price is a rip-off for a proprietary blend full of useless ingredients. If Iso Tone was $25 we’d still say it was over-priced because of the obvious filler ingredients in play here.
But $44.99 is outrageous.
That is a similar price to some of the highest-spec fat burners on the market today.
We think you can get a lot more bang for your buck with a different product. Iso Tone is far too expansive; we think it’s probably just Sesame Seed Oil anyway!
Iso Tone Review Summary – Is It A Good Fat Burner?
In our opinion, Iso Tone is an extremely over-priced, under-powered fat burner. It simply cannot deliver the same kind of results as the best fat burners on the market today can.
For one thing, it doesn’t tell us the individual ingredient serving sizes. Instead, Iso Tone just lists all the ingredients as one big prop blend. This is always a sign of a rip-off.
These ingredients are just vegetable oils. The only ingredient capable of improving fat loss is the CLA-rich Safflower Oil.
Not only do we not know how much of this CLA-rich oil we get per serving, but CLA is not a particularly powerful fat burner anyway!
So the best case scenario with Iso Tone is that it produces modest fat loss in some users.
The worst case scenario – the one we think most likely because of the use of a proprietary blend – is that it is 90% Sesame Seed Oil.
Basically, if you want to see a significant improvement at the end of your next cut, use a professional-quality fat burner that provides more than some benign vegetable oils in a scammy proprietary blend.
