Looking for a weight loss product to give you a little edge?

If you want to boost your chances of success with your fat loss diet plan, you might be hunting down the weight loss supplements at your local GNC.

A quick discussion with the sales rep however often informs you enough to know that they aren’t all that well-trained in much other than promoting whatever product they earn the highest commission off of.

Therefore, doing your own research is key.

To help make things easier for you, I’ve come up with what I would consider to be the top products at GNC for weight loss.

Here’s the line-up to consider.

#1: Cellucor Super HD

The Cellucor brand is well-known for churning out quality supplements, and their Super HD formula definitely tops this list.  It’s not only the highest rated thermogenic fat burner on the GNC website, but we have also personally tested it with great results.

Like most of the weight loss pills you’ll see on this page, it contains a number of different stimulants to not only help curb your appetite, but also help with boosting your energy levels.

One additional component to Super HD is it’s nootropic effect.  Some of the ingredients in their formula have been associated with feelings of calm and focus, something that is certainly a plus when your in the gym.

You can find Super HD for about $45 for 60 capsules, which is about a 1 month supply.

#2: Meratrim

meratrim at gnc

Meratrim is a stimulant free plant based weight loss supplement.It’s all natural, gluten, soy, and sugar free, and it makes the very reasonable claim that you can start losing weight in 2 weeks.

They call it a Fruit and Flower formula, with both of its two key ingredients housed within an 800 mg proprietary blend.

Garcinia Mangostana is the Fruit.It is said to work by suppressing appetite, blocking fat absorption, and by increasing the use of stored fat.

Sphaeranthus Indicus is the Flower.It may help control the way your body uses glucose.

According to preliminary research however, it seems that a 150 pound person would need to take over 2 grams per day to achieve the benefits.

There is actually a study showing that over a 16 week time period, subjects taking Meratrim lost over 8 pounds more than those using the placebo.

One thing to note here is that because Meratrim is a popular product on Amazon, there are hundreds of customer reviews, and it’s not good news. There are more 1 star reviews than 4 and 5 star reviews combined.

There are no complaints about side effects to speak of.

It’s really just customers stating it just didn’t work for them.

If you want to give it a try yourself, GNC carries the 60-count bottle (a one month supply) for $31.99.

#3: Lipozene

lipozene at gnc

Lipozene claims you can lose weight without changing your lifestyle – you can still eat all your favorite foods and you don’t need to increase your exercise routine.Personally, I’m very suspicious of products that make claims like these, but it’s a popular supplement so it’s worth looking into.

The active ingredient in Lipozene is 1500 mg of Amorphophallus Konjac from the Konjac Root, aka Glucomannan.It’s a water soluble fiber that expands in your stomach.

The idea is that becomes a gel-like substance in your stomach that makes you feel full. (Source)

Obviously, if you feel full, you’ll eat less, so even though you may be eating the same foods you always ate, the fact that you’ll feel more full means you’ll naturally eat less.

This claim is based on a small study of 20 obese participants who were instructed not to change their eating or workout routines.

The study was conducted over 8 weeks time.

The group taking the Glucomannan lost 5.5 pounds while the placebo group lost only 1.5 pounds.

Of course, if you really want to lose weight and keep it off, you will need to change your diet and activity level, but there’s something to be said for using Lipozene as a non-stimulant aid to help the process along.

GNC sells a 2 bottle package, each bottle a 60-count, for $17.88. At the recommended dosage of 2 pills taken 3 times a day before meals, the package will last just short of 3 weeks.

#4 – Zantrex 3 Fat Burner

zantrex 3 blue bottle at gnc

We’ve been getting a lot of feedback from visitors on Zantrex 3.  There’s actually two different formulations for this supplement…a Red bottle and a Blue bottle.

Click Here to see a comparison of the two.

Personally speaking, and this is reflected in the various reviews we’ve been getting, I think the Zantrex 3 Blue bottle is superior.  It contains 3 fat burning stimulants such as yerba mate, guarana, and damiana extract, as well as caffeine, so it packs a bit of a punch.

But it does work GREAT for providing energy and motivation for the gym, as well as helping to curb appetite.

I experienced no side effects at all from the Blue Bottle, however the Red Bottle gave me various side effects like headaches, dizziness, and a rapid heart beat.

Unfortunately GNC no longer sells Zantrex 3, however you can find it available for sale in Walmart and other locations.

#5 – BIORhythm AdrenaLean

adrenalene reviewIf you want to see a major change in how you feel and function on a daily basis while using your weight loss support product, BIORhythm AdrenaLean is one to consider.

It is a more powerful product, so there will be a risk of side effects such as possibly feeling jittery, anxious, and having issues sleeping.This is due to the fact the product does contain stimulants including caffeine, so will rev up your central nervous system.

But in turn, this is also what allows it to give you the significant energy boost, which will be appreciated as you head into your next workout session.

In fact, Adrena Lean doubles as both an effective weight loss pill AND a pre workout supplement.

Even though the product claims to have no jittery side effects, it does contain caffeine so you need to know your own body.

Many people are sensitive so if you do react, you will notice it.

It also contains Hoodia Gordonni, which some market for weight loss, and its appetite suppression ability.

On the contrary, according to the Mayo Clinic, it has not been scientifically proven, and the Federal Trade Commission calls such claims misleading.


You’ll also take in Yohimbine, which can help to assist with the burning of stubborn body fat stores, especially in the lower legs or abdomen.

Finally, you’ll take in synephrine, which also helps to stimulate the CNS, providing you a boost when you need it.

This product should be taken in a 1-2 capsule does per day, starting with one to assess your tolerance.  You’ll pay $29.88 for a 60 capsule bottle, putting in on par with most other fat burners in price.

#6 – Z-Burn

z burn reviewsZ-Burn is a product that is slightly different from many conventional fat burners because while most fat burners will make it harder to sleep, Z-Burn attempts to make it easier to sleep.

This product has been designed to help increase the rate in which your body oxidizes fat while also improving your metabolic rate over the sleeping period.

Since your metabolism will slow down significantly during the 8 hours you sleep, if you can do something to boost it upwards, this is going to have a very positive impact on you.

The product itself is very natural containing the ZMA combination (which is well-documented to help boost sleep quality), chromium to control blood glucose and insulin levels, along with L-Glutamine to strengthen the immune system, resveratrol for metabolic enhancement, valerian root and melatonin to promote deeper sleep, and L-Theanine to help promote relaxation.

If you struggle to feel energized and sleep well while dieting, this is a great product to look into.You can purchase it for $59.99 for a 60 capsule bottle, which will last between 1-2 months depending on the daily dose you use.

#7: GNC Total Lean CLA

gnc total lean cla reviewNext, CLA, otherwise referred to as conjugated linoleic acid, is a type of fatty acid that appears to have extra special weight loss benefits.

By supplementing with it, you can increase the rate in which your body naturally converts stored body fat to fuel, increasing the speed of progress.

Additionally, it can also help give you a metabolic boost as well, because it is a completely all-natural supplement containing just this form of acid, the risk of side effects will also be low.

This has all been proven in a clinical study involving overweight adults taking CLA for an extended period of time.

For those who are worried about putting a harsh product into their body, this is a great option to turn to.

You can purchase this product for $24.99, which will provide a full 45 day supply.

#8: Healthy Natural Systems Raspberry Ketone with Green Coffee Bean

Finally, raspberry ketones have caught on rapidly by the media as being one of the newest natural forms of weight loss supplements that you can use.Raspberry ketones are said to help boost your metabolism as well as help your body oxidize fat at rest.  This particular product takes things up one step higher by combining the raspberry ketones you find in other products with green coffee bean, yet another heavily touted substance that can assist with weight loss results.

Those taking green coffee bean regularly tend to notice faster results while following the same diet and exercise protocol as those who aren’t taking it.  Users are to be advised that this product may cause some slight tingling to occur in the mouth after consumption, however that should subside shoulder after taking it.  Otherwise, side effects reported are quite low, so it’s another safe product to look into.

It does come at a higher price tag however at $29.99 for 30 soft chews.You’re supposed to take 1-4 chews daily, so it will be a more costly product to use.

So there you have some of the top weight loss support products that you can purchase at GNC.
