Stacker Diet Pill: What You Need to Know
Posted on Jan 22nd 2010 11:00AM by Deborah DunhamStacker 2 and Stacker 3 are diet energy pills manufactured by NVE Pharmaceuticals that claim to help you burn fat and increase energy.
Both products contain caffeine, which accounts for the increased energy. They also contain synephrine which is structurally similar to ephedra (an FDA-banned substance in diet products) and can increase fat burning in the body. This combination of synephrine and caffeine make it a potentially harmful drug and may be associated with ischemic stroke and increased blood pressure according to the Mayo Clinic.
The difference between the dietary supplements is that Stacker 3 contains more caffeine. It also contains chitosan, a supplement commonly extracted from the shells of crustaceans, such as shrimp and crab that is thought to inhibit the absorption of dietary fat.Nutrition experts warn us about weight loss supplements.
"Any weight loss product that claims quick weight loss (more than two pounds a week), eat whatever you want and still lose weight, or all you do is take the pills without having to exercise is a short-lived weight loss promise," said Sarah Krieger, a registered dietitian and national spokesperson for the American Dietetic Association. "Without controlling food intake and exercise, diet pills will only be effective for the short term.
"Like many diet pills, Stacker contains an appetite suppressant and caffeine, so the idea is to eat less and have a boost of energy, which is supposed to motivate you to exercise," Krieger said. "The problem is that when a person stops taking the pills, the appetite returns."
Both Stacker 2 and Stacker 3 can be purchased online or in retail health stores.
