Lean System 7 Metabolic Activator and Metabolic Booster is an over-the-counter dietary supplement marketed to boost metabolism to promote weight loss. Lean System 7, sold by iSatori, contains a special blend of herbal ingredients, fruit extracts and hormone metabolites designed to work together to stimulate weight loss, improve immunity and memory, and slow aging. Consult your doctor before taking any dietary supplement.
Lean System 7 Proprietary Blend
Each serving of Lean System 7 contains 1,386mg of a proprietary blend of herbal ingredients. The blend includes yerba mate and green tea leaves, guarana seeds, dandelion leaf and root, 7-keto, and the patented fruit extracts Advantra Z and Bioperine, according to iSatori. The herbs or flowering plants, which include yerba mate, green tea leaves, guarana seeds and dandelion, work in different ways within the body to increase metabolism and stimulate the burning of fat. Advantra Z is the herb bitter orange, which contains the stimulant synephrine, a chemical similar to ephedra that increases heart rate and blood pressure. This may stimulate weight loss, but has negative side effects, according to MayoClinic.com. Bioperine is a fruit extract that increases the absorption of nutrients in the digestive system, and 7-keto is a natural metabolite of the steroid hormone known as DHEA or dehydroepiandrosterone. The makers of iSatori claim 7-keto increases metabolism, boosts the immune system and improves memory.
Fructo-Metaburn
A single serving of Lean System 7 contains 75mg of Fructo-Metaburn, a patented blend of the seaweed fucus nodosus and an extract of pomegranate fruit, according to iSatori. The fucus nodosus has been standardized to contain 10 percent fucoxanthin, a plant carotenoid that may possess antioxidant and anti-inflammatory properties, according to Dr. Julius Goepp of Life Extension. It may also contribute to weight loss by increasing resting energy expenditure and metabolic rate. Pomegranate is a healthy fruit with many antioxidants that may be useful in prevention of cancer and the treatment of heart disease and osteoarthritis, according to the University of Maryland Medical Center.
Other Ingredients
Lean System 7 contains four other ingredients: gelatin, rice flour, magnesium stearate and titanium dioxide, according to iSatori. These ingredients are commonly used by the pharmaceutical and nutraceutical industries for the development of tablets or capsules. Magnesium stearate is used as a lubricant to prevent the various ingredients in the capsule from sticking together. The other ingredients help maintain the structural integrity of the capsules or increase the shelf-life of the product.
