When buying supplements, many customers are looking to try something a little different than the medicines you might get from your doctor. Supplements are often based on traditional herbal remedies, using novel plant or mineral sources that supposedly have weight loss, muscle-building, or brain-boosting powers. Though not often backed by the evidence of scientific trials, traditional medicine can be a useful and harmless way to try different approaches to the common problems of obesity or a lack of energy.

Below we take an in-depth look into Slimvance, to see whether this traditional Ayurvedic herbal blend is the true weight loss breakthrough that its manufacturers claim it to be.

Slimvance Pros

  • Stimulant-free version of the product will not cause any side effects
  • All purchases protected by a clear money back guarantee

Slimvance Cons

  • Product is relatively expensive
  • Customer feedback has been generally negative
  • Most evidence suggests that the product will not work as advertised

What You Need To Know About Slimvance

Slimvance is a weight loss product that is based on traditional Indian (Ayurvedic) medicine. It comes in two distinct versions; a “stimulant-free” version using only the three traditional Indian ingredients (curry leaves, turmeric, and moringa), and a “regular” version that mixes the Indian ingredients with caffeine, garcinia cambogia, and others. Slimvance is manufactured by Body Dynamix, a subsidiary of GNC, which is itself one of the world’s biggest supplement manufacturers and health stores.

What Are The Side Effects Of Slimvance?

The “stimulant-free” version of Slimvance seems to come with no side effects at all.

The same cannot be said for the “regular” version, which uses a relatively strong serving of caffeine. When overconsumed, caffeine can cause jitters, sleeplessness, irritability, a racing heartbeat, more frequent urination, headaches, and shakes. The use of garcinia cambogia may also cause nausea, headaches, and digestive discomfort.

How Much Does Slimvance Cost?

A 30-day supply of either version of Slimvance costs $59.99, plus any shipping and handling charges the seller includes. Customers can choose to purchase Slimvance from GNC directly, or via Amazon or the special Slimvance product website.

Our Verdict On Slimvance

The manufacturers behind Slimvance claim that their product’s key ingredients are backed by a real scientific trial, which apparently indicated that the product induces weight loss at a rate that was effectively 6x faster than placebo. Mere minutes of research revealed this evidence to be highly suspect, and likely that the scientific trial is not trustworthy at all (it was paid for by a group that sold the ingredients as a weight loss pill). Unfortunately for Slimvance, every other bit of evidence we found suggests that this product not only fails to achieve such heady weight loss heights, but in fact fails to do much at all.

The customer reviews we found for both versions of this product on Amazon were generally negative, with numerous former customers leaving 1* reviews and complaining of the product’s uselessness. The key ingredients this product uses are not even well-known for inducing weight loss (even by traditional practitioners), leaving us to conclude that it does next to nothing. The “regular” version of this product does give a somewhat-useful dosage of caffeine and other weight loss ingredients, but at $60 per month, it remains far too overpriced for what can only be a very weak effect at best.

In our regular research of supplement manufacturers and stores, we often hear GNC described by customers as overpriced and low on quality (despite its professional money back guarantee and returns policy). On the evidence of this very poorly-designed weight loss product, we can only agree that GNC seems to be one to avoid when looking to find the best and most cost-effective products out there.

Overall, we do not recommend Slimvance to our readers.

Slimvance Review

Slimvance is a weight loss supplement that claims to represent something of a breakthrough in the world of thermogenic fat burners. The formula uses a patented Ayurvedic herbal blend containing curry leaves, moringa, and turmeric, and its benefits are supposedly proven by a real-life double-blind, randomised medical trial. Some versions of this product are “stimulant-free”, meaning that they contain nothing over than the basic herbal blend, and other versions mix the basic herbal blend in with caffeine and other stimulant-based weight loss ingredients.

Slimvance Facts

  • Manufactured by BodyDynamix, a subsidiary of GNC
  • Contains 120 capsules per normal pack, or 60 capsules per non-stimulant pack
  • Thermogenic weight loss product

Slimvance is manufactured under the BodyDynamix brand, which is a subsidiary of GNC. GNC is a multinational supplement store and manufacturer, and can be found online and in 9000 high street locations across the world. Compared to other protein powder and supplement stores, GNC is hugely expensive and is not always reliable in terms of high quality product options. Frequent customers also complain of pushy sales tactics in-store, and loyalty cards that fail to offer real savings to consumers. Despite some drawbacks, GNC is a multi-million dollar power player, and the first port-of-call for many supplement customers around the world. The company can be contacted by telephone (1-877-GNC-4700).

How to Take Slimvance

The directions for use are as follows:

For regular version: As a dietary supplement, take two capsules twice daily. For best results, take one serving in the morning and then another serving 30-60 minutes prior to exercise approximately 4-6 hours later. Do not exceed recommended dose per day. Do not combine with other products containing stimulants, such as caffeine. Do not take before bedtime.

For non-stimulant version: As a dietary supplement, take once capsule 30 minutes before breakfast and dinner. Do not exceed the recommended dose per day.

Slimvance Concerns:

  • Product has attracted mainly negative reviews
  • Key ingredient quantities not listed
  • Most indications suggest that the product does not work as advertised

What Does Slimvance Claim To Do?

There are some pretty bold claims made about Slimvance on the official GNC website, with the advertising copy hailing it as “the future of weight loss science”. The patented herbal blend supposedly offers targeted weight loss that can help customers “lose 3x more inches from your waist and hips”. The clinical trial on which these claims are based also supposedly indicates that customers can expect to lose weight without drastically changing their eating or exercise habits – “moderate exercise and an 1800-calorie diet” is apparently enough to induce weight loss whilst taking Slimvance. According to GNC, taking Slimvance will result in 6x more weight loss than with diet and exercise alone.

The formula is said to work through helping cells to metabolize fat cells more effectively, whilst also reducing the accumulation of fat and helping cells to break fat down faster. The key active ingredients are described as being excellent source of antioxidants and vitamins, which may improve overall health.

For the record, there is no advertised benefit of using the non-stimulant version of Slimvance over the normal version, other than that the non-stimulant version obviously avoids all the negative side effects associated with stimulants (such as jitters etc.).

Does Slimvance Work?

The hyped and patented herbal mixture that is common to both products is essentially a mixture of three Indian plants, namely turmeric, curry leaves, and moringa. We were unable to find any scientific evidence that these plants offered any weight loss effects, apart from one clinical trial that GNC repeatedly mentions on its site. The problem? This very flawed Indian study was funded by a group called Laila Nutraceuticals, who had the obvious intention of “proving” that an identical blend called Adipromin worked. Arrangements like these are always indicators of a compromised study motivated more by money and special interests than real findings.

Part of the reason we feel so confident calling this product a dud is the huge amount of negative feedback it has received from customers on Amazon. It seems that the majority of customers failed to lose weight whilst using Slimvance, with some even complaining of gaining weight.

In short, we would expect that the “stimulant-free” version of this product does absolutely nothing, and the “regular” version offers little more than a source of caffeine. Slimvance is potentially useful is you’re looking for a source of antioxidants, but don’t expect it to help you lose weight.

What Are The Ingredients of Slimvance?

The ingredients found in Slimvance are listed below. As mentioned above, there are actually two slightly different versions of Slimvance – a “regular” version with all the ingredients, and a “stimulant-free” version with just three ingredients. We will list all ingredients below, starting with “regular” Slimvance and ending with “stimulant-free Slimvance.

Unfortunately, the manufacturer does not provide exact ingredient quantities for every ingredient, which can make it difficult or impossible for customers to estimate how effective the overall mix is. The ingredient quantities that are listed are correct for two capsules of regular Slimvance and one capsule of stimulant-free Slimvance.

“Regular” Slimvance

  • Niacin 20mg (125% RDV): This vitamin is normally only useful in cases of deficiency, although very high doses are known to help lower cholesterol (higher than the dose used in this product). Source
  • Caffeine Anhydrous 200mg: Numerous studies have shown that caffeine boosts energy levels and alertness, as well as mildly boosting the metabolism, causing a small increase in the number of calories used by the body. The effects shown in studies a re small, and some studies are inconclusive. Caffeine is known to slightly increase athletic performance and mental performance. Source
  • Garcinia Cambogia Fruit Extract (60% Hydroxycitric Acid) 100mg: Test tube and animal research suggests that HCA, an active compound in Garcinia Cambogia, may be helpful in weight loss because of its effects on metabolism. However, numerous studies in humans have found it has no effect upon either appetite or metabolic rate. There is no evidence to suggest that Garcinia Cambogia works as a carb blocker either. Source
  • Capsimax Fruit Extract (Capsicum annuum) 33.34mg: Capsaicin, found in Cayenne pepper, is thought by some to play a role in weight loss. Some studies suggest it could suppress the appetite mildly, whilst others suggest that the heat causes a thermogenic reaction in the body, burning more calories for a period of time. However, there are also studies that show cayenne has little or no effect upon weight loss attempts. Source
  • Piperine from Black Pepper Fruit Extract (Piper nigruni) 5mg: Piperine, a substance found in black pepper, has recently been found to help block the formation of new fat cells, which could have a slimming effect. More research is needed to confirm. Source

Slimvance Patented Blend 450mg

  • Moringa Oleifera Leaf Extract: This plant has a strong antioxidant profile and may even some anti-inflammatory effects. Despite promise, it is almost never put into supplements in the quantities needed to be an effective antioxidant (this includes the dosage used in Slimvance). It has never been linked with weight loss effects. Source
  • Murraya Koenigii Leaf Extract: This plant also enjoys a reputation for being a source of antioxidants. One study has found a link between murraya koenigii and improving the neuropathic pain experience of diabetics. It may also lower blood sugar levels, but once again has not seemingly been linked with weight reduction. Source
  • Curcuma Longa Root Extract [Standardized to Curcuminoids = 31.5mg]: Curcumin is a yellow pigment that has numerous benefits, including reducing anxiety, soothing an upset stomach, and reducing inflammation and joint pain from osteoarthritis, leading to increased mobility in the elderly. There is very preliminary evidence to suggest that Curcumin supplementation could reduce the risk of prostate cancer and may improve blood flow. Curcumin does not appear to have any effect on cholesterol or weight loss and must be supplemented alongside compounds like bioperine in order to remain bioavailable and effective. Source

Does Slimvance Have Any Side Effects?

Customers should beware when using the “regular” Slimvance product, as the stimulant effects it has could cause some side effects. The “non-stimulant” version of Slimvance should have no side effects (as well as no beneficial effects).

Many of the most likely side effects customers should expect when using “regular” Slimvance are related to the high caffeine content. If overconsumed, caffeine can cause insomnia, rapid heartbeats, nervousness, restlessness, headaches, chest pain, shaking, and a ringing in the ears.

The Garcinia Cambogia found in the “regular” version can also cause some side effects, including nausea, digestive tract discomfort, and headache. Its long-term safety is unknown, as clinical studies typically focus upon short term use of up to 12 weeks.

Consult your physician prior to using this product if you are pregnant, nursing, taking medication, or have a medical condition. Discontinue use two weeks prior to surgery.

Are There Any Customer Reviews For Slimvance?

Both versions of Slimvance have attracted significant criticism in the Amazon review pages. The majority of reviews for both products are generally negative or lukewarm, with many customers reporting losing little to no weight, and with some even reporting gaining weight. A few customers still experience positive results, but it is notable that almost all point out their diet and exercise achievements as part of the success.

I spent $60 on this and I am 19 days in. I exercise an hour everyday and I watch what I eat. Do you know how much I’ve lost? Nothing. I’m still hungry, but I do notice I’m not nauseated from said hunger. I didn’t expect this to help me lose 10 lbs in a month, but one pound would be nice. This is the next best nothing.

I was talked into buying this garbage at gnc after going in for something else. Took as directed for 30 days. My workout routine and diet have been consistent for the last year so i was looking to get through a plateau. This garbage did nothing, I felt nothing, I lost nothing. Total waste of money.

Had high hopes on this whole reading the reviews. Unfortunately it made me gained weight instead of losing weight. Very disappointed.

Had to see for myself if this worked. And it did. 5 days in, lost 3 pounds. Doesn’t sound like much but was dying to get under 200. Now I’m sticking with it to see if I keep losing like all the other people I worked with.

I have been working out consistently for over a year and felt like i hit a wall with my BMI (body fat percentage, weight etc…) I’ve been taking this for about two weeks and kept on my diet and workout regiment as normal. I’ve lost six lbs so far. I plan on taking this for 90 days. Don’t think there are magic pills out there. everything needs to be combined with diet and exercise… This product i credit towards being able to break through the wall i hit after about a little over a year of consistent 4-6 days in the gym and dieting.

Does Slimvance Offer a Money-Back Guarantee?

All purchases made on the GNC website are protected by a 30-day money back guarantee.

    I tried to give this 30 days to work and it did absolutely nothing-even while eating healthier. And now I can’t get money back because it’s past 30 days?
