If you haven’t looked carefully at GNC Weight-Loss System, now’s your chance. In this article, we examined its side effects, ingredients, customer service, and clinical research. We also read tons of experiences. After, we condensed all of the information in order to give you the bottom line.

What is GNC Weight-Loss System?

Firstly, GNC Weight-Loss products do not have any specific ingredients because they include many products. Some of them include, Burn 60, Lean Shake Burn, and CLA. Stimulants are often used, but this isn’t a new thing.

All of these GNC Weight-Loss pills are manufactured and sold by General Nutrition Centers, which was established by David Shakarian. They sell a wide variety of supplements, ranging from herbal remedies to protein powder, and vitamins. The prices for their supplements usually start around $40 and can increase all the way up to $190. However, they do have a lasting impression in the market as a reliable seller of health products, but read on…

Lack of Weight-Loss – “No Results?”

The first issue we had with GNC Weight-Loss Systems was their lack of results, according to some customer reviews. “When people spend their hard earned money on a product, the last thing they want to happen is for it not to work,” says our Research Editor. “That is a complete disappointment.

According to one customer who used GNC Weight-Loss supplements, “These pills made no discernable difference with regard to weight loss, calorie burning or appetite suppression – and I have gained a few pounds while taking them.”

“This product did not work for me,” another agreed.

Everyone didn’t feel this way, however. One person wrote, “…[I] am very pleased with the results.”

Another individual said, “It REALLY WORKS!!! AWESOME AWESOME product!!!”

Negative Side Effects – “All Pain and No Gain?”

The second issue we had with GNC Weight-Loss System was some of its reported side effects. “One of the most common problems we see with any supplement is the issues customers experience while taking it,” says our Research Editor. “No one wants to use a product that has all pain and no gain.”

“At first this product worked for about four days I had more energy, curbed appetite, then I started to become irritable, nervous, tired, and nauseous to the point I couldn’t even sit up without feeling sick,” mentioned one customer.

Another agreed, saying, “I took this one time and it made me SUPER SICK.”

However, these side effects didn’t affect everyone. According to one review, “I’ve tried nearly every popular thermogenic/fat-burner on the market over the past 20 years, and while some may have more kick to them (and usually with bad side-effects), [this supplement] is the best balanced product of its kind.”

“…there was no shaky/antsy/jittery effect…” mentioned another.

After reviewing hundreds of supplements, we at DietSpotlight found that it can take something like negative side effects to push customers away and ruin that chance of lasting success. If GNC Weight-Loss shakes and pills have this problem, it can be a major one for the consumer as well.

The Science – “Is There Any Research?”

Although we do know that some of the ingredients found in GNC Weight-Loss System have some science backing them, the company claims that all are clinically studied. However, when you look at the research they provide, it says that the test was performed on one GNC multivitamin and the results showed that it increased levels of vitamins and minerals in the blood system. Unfortunately, this does no back up their other products. At DietSpotlight, we like to see some support before we give a recommendation, and in this case, we aren’t so sure there is enough.

The Bottom Line – Does GNC Weight-Loss System Work?

So, should you race out to get one of bottle of GNC Weight-Loss pills? Well, we do like that the company has been around for quite some time and that they offer a variety of health supplements. However, when we looked at the science, side effects, and results, we became hesitant to give this our recommendation.

If you are ready to lose weight, then we think you should try a product that produces real results, has no reports of harmful side effects with ingredients backed by significant science. Also look for customer reviews that talk about real, lasting results.

Among the best products we’ve seen this year is one called Dietspotlight Burn. It is a weight-loss supplement that has clinically tested ingredients, positive customer reviews, and no reports of harmful side effects. Plus, we love that representatives are friendly and helpful.

Plus, the company is offering a special trial offer, something we think you should check out.
