Stacker 2 Review – 6 Things You Need to Know
Stacker 2 is a diet and energy supplement that claims to be “the world’s strongest fat burner.” Apparently, this diet and energy supplement, made by one of the world’s top pharmaceutical companies, can boost energy levels and raise metabolic levels. However, with so many of the product’s ingredients containing high amounts of caffeine, the chance of potential side effects is higher than normal.
Our research team wanted to learn more about Stacker 2 and its effectiveness, so delved into the ingredient research on white willow bark, yerba mate, and guggulsterone. In the end, we compared the research we gathered on the supplement to the few available customer testimonials to see if this pill made by “diet & energy specialists” is as amazing as they claim.
Stacker 2 can be purchased through their Official Site.
What is Stacker 2?
First off, Stacker 2 is a fat burner using the principles of the infamous ECA Stack. The ingredients are yerba mate, green tea, guggulsterone, cassia mimosoides, white willow bark and caffeine 200mg. You’ll take one to three per day after meals. The blister pack makes it easy to take with you on-the-go. Supposedly, this formula promotes weight-loss by boosting energy levels and metabolism.
Stacker 2 was brought to the market more than 20 years ago by NVE Pharmaceuticals. It’s available in at local stores and through the official website. We like it contains a few natural ingredients and it appears to be affordable, but read on…
Stacker 2 Side Effects – “Look Out?”
The first concern was the intensity of Stacker 2 side effects. “This one contains multiple fat burners,” said our Research Editor. “While they’re supposed to boost metabolism, there’s a chance you could experience adverse reactions.”
“I noticed it also made me jittery and sometimes gave me a headache,” said one user.
“Even after doing intensive workouts I still had too much energy. I had to stop taking them, because occasionally I had caffeine crashes. They are not fun at all,” offered another.
Side effects are rare, so we found some users that didn’t experience adverse reactions.
“No headache, jitters or anxiety like other caffeine pills,” commented a dieter.

Results – “No Weight-Loss!”
Based on some Stacker 2 reviews, there’s were customers that didn’t notice results. “I did not experience any weight loss on this product. I did have more energy but I was looking for a fat burner,” said one customer online.
“The pill does give a great amount of energy, but the claim of it being a fat burner is bogus,” said a user.
Upon reading further reviews, some customers noticed results. “I tried them again and they helped me lose weight,” explained a customer.
“After the first one, I felt warm and could tell my metabolism was increasing,” stated another.
Our research has shown if there is some particular part of a diet supplement that’s troublesome, like not producing results, the likelihood of long-term success is slim. If Stacker 2 doesn’t help you lose weight or burn fat, is it really worth it?
The Science – “Legitimate?”
Some of the Stacker 2 ingredients have been clinically verified to work. The white willow bark extract, green tea extract and kola nut are common ones that have been shown to be mildly effective. However, the any results aren’t connected to this formula. We at DietSpotlight find clinical research to be important to the review process. When there’s no solid-science used to support the claims, we have concerns.
What Users Are Saying
“I love this product. It gives me energy and helps to suppress my appetite.”
“I did not experience any weight loss on this product. I did have more energy but I was looking for a fat burner. Decent product though for energy but I’d rather have just caffeine.”
The Bottom Line – Does Stacker 2 Work?
Will Stacker 2 help you lose weight? Well, we like that it contains few natural ingredients and that we found some positive customer comments, but the lack of research showing it works is concerning. Also, reports of negative side effects and no real results leaves us a bit skeptical about giving it the thumbs up.
If you are still in the market for an effective fat burner, we suggest going with one that’s clinically proven to work, without any mentions of harmful side effects.
Among the best products we’ve seen this year is one product called Burn TS. The formula contains four ingredients, clinically-tested, with results often located in The American Journal of Clinical Nutrition and the Journal of Medicine.
The company behind Burn TS is offering a 2-Week Sample as a sign of confidence in their supplement.
