Lean System 7


Isatori's Lean System 7: Clinically Tested Metabolic Activator


Isatori's Lean System 7 is a clinically tested metabolic activator and fat burner. It features a proprietary blend of herbal compounds including 7-keto, yerba mate, guarana, green tea leaf extract, citrus aurantium, dandelion, bioperine, fucoxanthin and pomegranate.

A randomized, double-blind, placebo-controlled study published in Nutrition found that participants using Lean System 7 had a significantly increased resting metabolic rate and decreased bodyfat from their waist and hips than those who dieted alone.

Green tea extract, yerba mate, citrus aurantium and guarana are potent methylxanthines that promote energy and alertness, improve mental and physical performance and boost the metabolism and fat loss. Yerba mate also promotes a feeling of satiety (fullness) and has diuretic properties. The addition of dandelion, a mild herbal diuretic, helps reduce excess subcutaneous water.

Patented 7-KETO is a natural metabolite (breakdown product) of DHEA (a hormone precursor) that doesn't convert into testosterone or estrogens and has been shown to increase thermogenesis and improve fat loss. Bioperine is a standardized extract of Piper Nigrum L (black pepper) that stimulates the thyroid, induces thermogenesis and increases fat loss. It also enhances gastrointestinal absorption.

Fucoxanthin is a plant carotenoid found in seaweed that can increase fat burning without stimulating the central nervous system. Combined with pomegranate seed, it synergistically restores and increases the metabolic rate.


Since 2002, over one million bottles of Lean System 7 have been used by people worldwide to promote safe fat loss.

Lean System 7 has the following benefits:

  • Clinically researched metabolic activator
  • Elevates resting metabolic rate
  • Increases fat loss and calorie burning
  • Promotes a feeling of fullness


Green tea, yerba mate and guarana may cause insomnia, trembling, anxiety, and urinary frequency. If you regularly drink coffee or caffeinated beverages, Lean System 7 should be taken in place of your caffeinated beverages, not in addition to them. Individuals that are sensitive to caffeine's stimulant effects should avoid taking Lean System 7.

Citrus aurantium (synephrine) should not be combined with prescription medications.

The long-term safety of 7-KETO has not been determined.

People with a confirmed sensitivity to inulin fiber found in dandelion should avoid Lean System 7.
Pregnant or lactating women and people with pre-existing medical conditions or taking medication should not supplement with Lean System 7 without consulting a physician.
