FenBurn is a fat loss supplement that is meant to increase your metabolism and help you to quickly burn fat. The supposedly unique fat loss formula functions as a thermogenic and contains 100% natural ingredients including essential vitamins, minerals and anti-oxidants. It claims to a help a person reach their weight loss goals by suppressing appetite, intensifying workouts, enhancing focus, preserving muscle mass, and continually breaking down fat stores.
When this review was written, a single bottle (a 30 day supply) cost £29.95 ($43.00) and the active ingredients included: Bitter Orange Peel, Bioperine, Caffeine, Capsaicin, L-Tyrosine, Green Tea Extracts, Oolong Tea Extracts, Vitamin B12.
One look at these ingredients shows that there isn’t anything particularly “unique” about FenBurn’s formula as these same ingredients can be found in many other fat burners on the market.
Nevertheless, some of these ingredients have been studied to determine their effects on weight loss. What some research has found is that bitter orange peel (also known as bitter orange and citrus aurantium) is a thermogenic that boosts overall body temperature, resulting in better metabolic rate because the body must burn more fat to obtain the energy it needs to create the heat. It also increases heart rate and blood pressure and enhances the effects of caffeine. Caffeine boosts energy and mental alertness and can enhance fat burning especially when combines with physical activity.
Green tea extract is rich in catechins, which is thought to help boost metabolic rate and improves fat burning. Oolong tea improves metabolic rate and is also said to prevent the storage of dietary fat. Capsaicin is also a thermogenic that increases body temperature and accelerates metabolic processes. Bioperine helps the body to better absorb nutrients and the pill’s other ingredients while Vitamin B12 is also believed to boost energy.
That being said, in spite of all the benefits that these ingredients may provide, none of them have been clinically proven to cause weight loss.
Be advised that taking FenBurn may increase the risk of certain side effects such as insomnia, restlessness, anxiety, jitteriness, rapid heartbeat, headache, stomach upset, etc. This is because the product contains caffeine and other stimulants. Moreover, this OTC diet pill could also increase blood pressure and boost the possibility of other dangerous cardiovascular effects like fainting, stroke and heart attack, even in healthy individuals, due to the fact that it combines both caffeine and synephrine, which is a naturally occurring stimulant found in bitter orange.
Prior to taking FenBurn it is advised that you first speak with your healthcare provider to make sure it is a safe option for you.
