Slimvance Stimulant Free vs. Iso Tone Formula Comparison

Slimvance Stimulant Free has a very short ingredient list, putting all of its faith into three herbal extract ingredients: moringa oleifera leaf extract, murraya koenigii leaf extract, and curcuma longa root extract.

  • It Has the Research: Slimvance Stimulant Free might only have three ingredients but this unique combination has been put to the test and that study shows the effectiveness of the supplement as long as its combined with a healthy diet and exercise.
  • 12 VS 2: According to the study mentioned above, subjects lost an average of 12 pounds. Compare this to the two pounds in the placebo group, and you can see why this supplement might turn some heads.
  • Get Slim: Slimvance Stimulant Free doesn’t just drop pounds on the scale, but it’s been shown to promote inches lost as well. Subjects lost an average of over 2 inches when taking Slimvance Stimulant Free.

Iso Tone takes a unique approach to fat burning by giving you more fat. Dietary fat has had a terrible reputation in the last few decades thanks to paid-for studies by the junk food industry. Now that the real science is out to the public, healthy fats are being embraced. Iso Tone is one such example of improving your health via fat.

  • Fight Fat with Fat: Iso Tone contains a variety of healthy fats including safflower oil extract, fish oil, and borage oil extract.
  • Great Line-Up, Questionable Dosage: Iso Tone contains fatty acids that have been proven to promote fat burning, but the problem is that the dosage per serving is pretty low.
  • No Fish Burps: Somehow these are still a thing with modern day supplements, but not so with Iso Tone.

How are Slimvance Stimulant Free and Iso Tone formulas similar?

The only way in which the formulas of these two supplements are similar is that they both make use of proprietary blends, which is unfortunate.

Slimvance Stimulant FreeIso Tone
Mystery Dosage Proprietary BlendYesYes

The issue with proprietary blends is that you see the ingredients you’re getting but you have no idea how MUCH you’re getting of each individual ingredient.

Let’s say that you want to take moringa oleifera leaf extract, found in Slimvance Stimulant Free, for your weight loss. You want to take the exact amount used in the study.

You know that the fat burner ingredients in Slimvance Stimulant Free, but you’re not sure how much they are using because the frustrations of the proprietary blend. Unless you’re buying moringa oleifera leaf extract as an individual ingredient, you’ll never know if you’re reaching that mark to achieve results.

  • The best fat burner supplements tend to avoid using proprietary blends at all costs, so both Slimvance and Iso Tone drop the ball when it comes to dosage.

How are Slimvance Stimulant Free and Iso Tone formulas different?

Now, we’re talking! These two supplements couldn’t be any more different if they tried.

  • One of these stim-free fat burners is based on herbal extracts, and the other has a concoction of oils and fats. It’s important to note that one way isn’t necessarily better than the other.

Those herbal extracts found in Slimvance Stimulant Free have been shown to encourage fat loss while the fatty acids and oils in Iso Tone have also been suggested to support weight loss. The dosage is the problem…but more on that below.

First, let’s explore how different these two really are.

There are three key ingredients found in Slimvance Stimulant Free that you won’t find in Iso Tone.

Moringa Oleifera Leaf: Shown to promote a thermogenic response in the body, moringa oleifera leaf might be an effective way to amp up your fat burning.

Murraya Koenigii Leaf: This Ayurvedic extract has been used as an overall wellness aid for thousands of years, but it’s now drawing attention as it’s been shown to possess anti-inflammatory and fat burning properties.

Curcuma Longa Root: More commonly called turmeric, this popular spice has also been a long-time health aid, promoting proper blood sugar levels and supporting weight management.

Iso Tone contains three ingredients for fat burning that you won’t find in Slimvance Stimulant Free.

Safflower Oil Extract: This high-fat oil has been standardized to 80% CLA (conjugated linoleic acid), and this is great news as CLA has been shown to stimulate the PPAR receptor and increase fat burning.

Borage Oil Extract: An incredible fat burner when properly dosed, borage oil extract has been shown to block fat storage and increase metabolism.

Fish Oil: One of the most popular ingredients in supplements in the last decade, fish oil is great for heart health and healthy weight management.

Slimvance Stimulant Free vs. Iso Tone: Which is the better formula?

You’ll be hard pressed to find two formulas that are more different from one another. One herbal extract-based, another fatty acid-based, these two supplements both have science backing them up.

  • However, only Slimvance Stimulant Free has an actual study backing its efficacy.

That is going to give Slimvance Stimulant Free the extra bump it needs to put it ahead of Iso Tone as far as formula. When it comes to dosages, that’s going to be the nail in the coffin for Iso Tone (more on that below).

Slimvance Stimulant Free might have a bigger price point, but you can rest assured you’ll be getting enough of the supplement for each of those 45 days.

The problem with Iso Tone is that you can take up to three servings per day, and with its weak dosage, you’ll have to if you want to see any results. However, if you take two servings per day, you’ll turn your 45-day supply into a 20+ day supply. Want to take three servings per day? You can, but now you have enough for two weeks. Make it a monthly habit and you can see how this adds up quickly.

As a GNC product, Slimvance Stimulant Free is only available on the company website, but GNC is also famous for great weekly deals so keep your eyes open for a BOGO offer or something similar.

Iso Tone can be found on numerous website such as Amazon and If you’re a frequent shopper on either one, you already know that these websites always have sales and discounted prices.

Slimvance Stimulant Free vs. Iso Tone: Which is Better?

Iso Tone has an excellent line-up of natural and healthy fats that have been shown in studies to promote fat burning and weight management. On paper, the ingredients look great. The problem is in the dosages. 1,600 mg of a proprietary blend isn’t much when you consider one capsule of a simple fish oil supplement contains 1,000 mg (and it’s a fraction of the price). Iso Tone has great ingredients, but it doesn’t have enough of them to justify itself as a serious and economical fat burner.

Slimvance Stimulant Free might also have a proprietary blend, but it also has a study dedicated to it, demonstrating that the herbal extracts inside are effective for fat loss and weight management.
