Stacker 2 Review
Sold by NVE Pharmaceuticals, Stacker 2 uses a proprietary blend to produce a "powerful fat burning diet supplement." NVE Pharmaceuticals claims it will "burn fat, cut cravings, and combat diet fatigue" when combined with diet and exercise. Its predecessor, Stacker, was forced to be reformulated because of its use of ephedra.
Ingredients and Mechanism of Action
Stacker 2 uses a stimulant based mix that is likely to increase metabolism and possibly produce a thermogenic effect. They use many ingredients that have recently been popularized in the diet industry such as caffeine, kola nut, yerba mate, green tea, and gymnema. The website boasts a number of positive customer testimonials that seem to attest to its usefulness in promoting weight loss.
Results in the case of Stacker 2 do not come without negative side effects. With the high levels of caffeine included in Stacker 2 side effects include nausea, headaches, accelerated heart rate, insomnia, anxiety, and diarrhea. Some would go with the policy of forgive and forget. However, in the case of products that have used ephedra before the ban, there is a definitive pattern established.
All of these products took the easy and popular way before, without doing their own research and studies to protect the consumer. Unfortunately, they continue in this pattern, even after the extreme loss of revenue all of them experienced with the ban of ephedra. Stacker 2 is no exception. Their ingredients in some cases are effective, but they are popular and can be found in every other diet supplement on the market.
Overall Impression of Stacker 2:
Stacker 2 may produce some results, but not without major unwanted side effects. All of the positive testimonials posted also complain of these side effects. Stacker 2 has a history of taking the easy and popular way and not doing their homework. As such, I would look for a company and a product with a better reputation.
