Lean System 7 ingredients

Lean System 7 contains a proprietary blend of 7 fat burning herbal compounds. The exact blend differs slightly depending on the country where Lean System 7 is bought. The Lean System 7 formula contains:

Green tea: There is some evidence that green tea can promote weight loss (Mol Nutr Food Res 2006;50: 176-87; Am J Clin Nutr 81: 122-129; Journal of the International Association for the Study of Obesity 2000;24: 252-8; The American Journal of Clinical Nutrition 1999;70: 1040-5). Green tea contains caffeine. Users sensitive to caffeine could experience any of the following side effects: restlessness; irritability; sleeping problems; tremors; heart palpitations; loss of appetite; upset stomach; nausea; frequent urination; and skin rash.

Guarana: Guarana may cause side effects, but many people have no, or minor, side effects. Side effects can include: Anxiety; diarrhea; headache; increased urination; nausea; nervousness; shakiness; tremors; trouble sleeping; upset stomach; vomiting.

Yerba mate: Flushing, nausea, vomiting, irritability, nervousness, increased urination and headache may occur with yerba mate. If any of these effects persist or worsen, contact your doctor promptly. Stronger but very infrequent side effects include stomach pain, yellowing eyes and skin, dark urine, fever, muscle twitching, unusually fast/slow/irregular heartbeat.

Citrus aurantium: Theoretically, Citrus aurantium extracts should promote fat burning since its active ingredients (synephrine and phenylephrine) are both sympathetic alpha agonists. This plant contains synephrine. There are studies that indicate that Synephrine can elevate blood pressure and heart rate (e.g. Ann. Pharmacother. [2006] 40(1):53-7).

Dandelion root/leaf: This plant is also included in the formulation for its diuretic properties. Dandelion is generally considered to be a relatively gentle herb without any serious side effects. However, some people have reported allergic reactions from merely touching dandelion but this is rare. Patients who are on pharmaceutical diuretics or drugs that have a diuretic action should not take supplements containing dandelion. In such cases, one of the possible side effects/interactions of dandelion is that it could lower the potency of the synthetic drug. Individuals on diabetes medications should also be aware that dandelion might increase the blood sugar lowering effects of those pharmaceutical drugs.

Bioperine: Bioperine is a standardized extract from the fruit of Piper nigrum L (black pepper), or Piper longum L (long pepper), that contains 95 percent Piperine. Piperine, in the patented form of Bioperine increases the body’s natural thermogenic activity. It also enhances the body’s absorption of nutrients. No significant Bioperine side effects have been reported so far. Minor gastrointestinal discomfort or GI symptoms may occur with high doses of Bioperine. Studies have not been carried out to determine the side effects of chronic supplementation with Bioperine.

Fucus nodosus (standardized to 10% fucoxanthan): Fucoxanthin is a type of carotenoid found naturally in edible brown seaweed and used in some weight loss products. It is claimed that fucoxanthin can boost metabolism and stimulate fat burning. Because there have been no clinical studies with Fucoxanthin, potential side effects are not known. It should be noted that large amounts of Wakame, or other types of seaweed, should not be consumed as a source of Fucoxanthin. Seaweed is rich in iodine and excessive consumption may result in iodine poisoning. High levels of iodine can interfere with the function of the thyroid gland. Also, consuming excess amounts of iodine-rich foods is not recommended if there is a known allergy or hypersensitivity to iodine.

Pomegranate extract: Studies on pomegranates for medical uses are few. Preliminary animal studies show promising results with this extract for weight loss. For most people, pomegranates do not cause significant side effects. However, allergic reactions are possible, even in people who have eaten pomegranates for years. Because these reactions can be quite dangerous, it is important to know the possible signs and symptoms. These can include: an unexplained rash, hives, or itching; wheezing or difficulty breathing; swelling of the lips, mouth, tongue, or throat; difficulty swallowing. Seek medical attention immediately if you think you may be having an allergic reaction to pomegranates.

7-Keto-DHEA: This is a naturally occurring metabolite of DHEA, a steroid hormone produced in the body, and believed to enhance metabolism. Because 7-keto-DHEA cannot trigger potentially dangerous levels of estrogen and testosterone in the body, which can occur in some patients who use DHEA, scientists now consider that 7-keto DHEA may be a safer alternative.
