Natrol Triple Lean is a self-proclaimed triple fat burner. The product description claims to increase thermogenesis, decrease appetite and metabolize fat. The ingredient list is available online, though the supplement appears for widely varying prices. We found no official website listing for the product, which could mean the supplement is no longer available. Dieters are instructed to take the supplement before each meal to decrease appetite and increase calorie burn.

List of Ingredients

Calcium, Garcinia Cambogia, Theobroma Cacao Extract, Green Tea Extract and Caffeine.

Product Features

Three of the five ingredients in Natrol Triple Lean are proven to have positive effects on weight loss. Calcium has been tested on mice. Mice eating low-fat calcium sources lost up to 69-percent body fat. While this is not a human study, experts believe low-fat calcium and calcium supplements have a positive effect on fat loss. In order for calcium to be absorbed through supplementation, zinc, magnesium and vitamin D need to be taken at the same time as calcium. This supplement does not include these ingredients.

Green tea extract increase metabolism and supplies caffeine. Caffeine boosts metabolism and calorie burn. Some forms of supplemental green tea extract are standardized for EGCG. EGCG boosts metabolism with or without the presence of caffeine.

Caffeine is a stimulant with metabolism boosting effects, but too much caffeine can cause negative side effects. Some dieters are sensitive to caffeine while others drink enough coffee and caffeinated beverages to reduce sensitivity. Dieters should always take the lowest dose of a weight loss supplement containing caffeine or other stimulants to assess how the body reacts.

Garcinia cambogia is included as a fat burner, but the effect on the body is under review. Some dieters have reported liver damage associated with hydroxycitric acid, another name for garcinia cambogia. It is best to avoid all products containing this ingredient until thorough testing has been completed. Theobroma cacao extract is another source of caffeine.

Conclusion

The ingredient list for Natrol Triple Lean is not much different from hundreds of other fat burners. There are three proven ingredients, but a strong appetite suppressant is missing from the formula. When a supplement increases metabolism, it may also increase hunger so an appetite suppressant is important. There may be too much caffeine in the supplement for dieters sensitive to stimulants. Negative side effects of caffeine can last 12 hours or more.
