Slimvance has seen significant hype lately and for good reason, this product is pretty much GNC’s fat burner pill poster child! These diet pills are a self-proclaimed “core slimming complex” that can apparently cause 6x more weight loss than dieting alone. With claims like these we just had to investigate for ourselves; in this Slimvance review, we’re taking a look at this products formulation and establishing what consumers can and cannot expect from it.

Some Quick Information About Slimvance

Slimvance Core Slimming Complex is a thermogenic fat burner pill produced by a company named PLT Health Solutions LLC (trading as BodyDynamix) and distributed by GNC Holdings Inc (trading as GNC).

One bottle of Slimvance costs $59.99, contains 120 capsules and will last consumers for 30 days. The product itself is essentially a blend of caffeine, capsicum and garcinia cambogia (among other ingredients), though it also comes in a stimulant-free version, which is caffeine-free.

Consumers are promised effects such as the increase ability to burn and metabolize body fat, the ability to burn calories faster (“12x faster”), suppressed appetite levels and a 3x reducing in hips and waist size.

Does Slimvance Work?

Based on our research into this product, we do not believe it will work directly as described by GNC. We believe there is a lot of misleading information about Slimvance online.

Firstly, there are no officially recognized “fat burning” ingredients inside Slimvance (though that isn’t to say there aren’t independent studies that state otherwise). As both the FDA and EFSA have not conceded that ingredients inside Slimvance burn body fat, boost metabolism or suppress appetite, it’s very safe to say the product is unable to consistently perform such functions for 100% of consumers.

Claims that this product can cause you to burn 12 times more calories than normal, lose 6 times more weight than normal and reduce your hip & waist size by 3 are all unfounded and unproven. Studies are cited on the packaging and website that apparently support the claims, however there are no details provided for these studies.

On a more positive note, the product is high in stimulants and will be an excellent pre-workout pill that’ll let you work harder in the gym. If you are going to use Slimvance for the purposes of weight loss, you must ensure you use it in conjunction with a calorie-restricted diet and robust exercise regime.

What Claims Are Being Made About Slimvance?

We have found the following claims and/or implications being made about this supplement:

    1. Causes consumers to burn 12x more calories – Not an officially recognized health claim*
    2. Delivers 6x more weight loss – Not an officially recognized health claim*

*These statements have not been evaluated by the FDA and have not been approved by the EFSA. The packaging indicates that the manufacturers conducted private studies to support these claims, however the clinical trail details are not revealed.

Are There Any Reviews From Customers?

We have found the following Slimvance review testimonials via the GNC website:

I’ve only been working out for one week after taking 6 years off due to our family expanding by 2 kids. I’m 25 lbs over what I was 6 years ago. Started taking this product to help kickstart weight loss. With an 1,800 calorie (or less) per day diet, daily exercise, and drinking lots of water, I lost 4.6 lbs my first week. I’m a 40 yr-old male who has been athletic my entire life.

Besides weight loss, this increased my focus, increased my overall attitude, and in general makes me feel great. I like that there is no caffeine. I would recommend this to anyone. It’s working for me, and I plan to take it for at least 3 months.

The product appears to work but it’s takes time
To see results. I have been loosing inches in my cloths and people at work have been noticing that I have lost weight. I haven’t weighed myself yet. Wish me luck!

As GNC has the official distribution rights to Slimvance, we cannot fully guarantee these reviews have not been manipulated.

Where Can I Buy This Product?

This product is available via the official GNC website ( and Amazon.

Our Conclusion.

To conclude our Slimvance review, it’s a bit of a mixed bag – there are things that we like about it and things that we aren’t too blown away by. It’s our opinion that there is a lot of misinformation on this product.

BodyDynamix make numerous of non-FDA-approved statements on the abilities of Slimvance, which we feel are not an accurate representation of effects the typical user will experience. While this is definitely a great product to use for those looking for massive energy and metabolism boosts, we don’t buy into the claims that this product helps consumers burn 12x more calories than normal.

It’s likely that the majority of gym-goers will find Slimvance very useful when taken pre-workout, as ingredients inside this product will enhance your focus levels and reduce your perceived rate of exertion, however the downsides are that this product is that it comes with some potentially negative side effects, BodyDynamix aren’t fully transparent on the individual ingredient amounts per serving and finally the price tag is quite high for a 1 month supply of pills.
