LeanFire supplements have become a popular choice for bodybuilders and athletes interested in losing weight quickly. It is a diet pill that provides a boost of energy to increase the metabolism, and promises to support an ‘active and healthy lifestyle' by reducing the appetite and working primarily as a fat burner. But how effective is it?

About LeanFire Diet Pills

LeanFire fat burner supplements are manufactured by InStone, a company that produces a full line of high performance supplements. They are made with a combination of ingredients and herbal extracts and contain a significant amount of caffeine from green tea. The caffeine in LeanFire is equivalent to almost three cups of coffee, and this in itself can make a significant impact on the person taking it. LeanFire recommends three capsules once or twice per day for maximum benefits. Most people will need to adjust their dosage according to their current weight and tolerance level, especially if they are particularly sensitive to caffeine.

Key Ingredients in LeanFire Diet Pills

LeanFire diet pills contain green tea for caffeine, along with a series of herbs and standardized extracts. The pills include:

• Rhodiola rosea root: an ingredient that has been linked to sustained mental focus during complicated activities. This can be helpful for anyone taking part in strenuous workouts coupled with a long day at the office.

• L-Tyrosine: an amino acid that has been linked to healthy thyroid levels. This is commonly used in many diet pills to boost the mood, and some studies suggest that L-Tyrosine plays a role in improving concentration as well.

• E & Z Guggelsterones: these are becoming a widely used ingredient in many diet pills as they may have a positive effect on thyroid function. Many bodybuilders and athletes need supplements that boost the levels of T3 and T4 thyroid hormones in the body. E&Z Guggelsterones have been linked with a positive effect on the thyroid, and may even help balance out unhealthy cholesterol levels.

• 7-KETO: this ingredient is being used in many dietary supplements and weight loss aids because of its positive effects on the thyroid.

• Evodia rutaecarpa: this is a fairly new ingredient in the diet supplement market, and clinical trials and results from studies are limited. Still, some exeprts claim that the extract can reduce the body's fat-accumulation processes, and may help burn off excess fat by increasing the body's basal temperature.

Potential Side Effects of LeanFire Diet Pills

LeanFire diet pills have not been approved by the FDA, and may have significant side effects. Anyone taking prescription medication of any kind should be especially cautious about taking LeanFire---or any other diet pills---as the ingredients do have a high risk of drug interactions.

Caffeine sensitivity is of primary concern with LeanFire, since many people cannot tolerate three cups of coffee comfortably. Common side effects of caffeine overdose include nervousness, restlessness, anxiety, panic attacks, and irritability. Taking LeanFire at the wrong time of day can also have a significant effect on an individual, and many people may experience bouts of insomnia and have difficulty achieving a state of healthy sleep on a regular basis.

Bottom Line: LeanFire diet pills are a powerful combination of caffeine and standardized herbal extracts, but there is limited information available on the safety and general use of these diet pills for the long-term. The combination of herbs and ingredients does look promising, but there is no confirmed evidence that these pills are safe, or that they do not have long-term side effects. The high amount of caffeine in these pills can be particularly harmful to those who are sensitive to caffeine, and LeanFire does run the risk of creating a variety of health problems in the future.
