Research on African mango shows beneficial effects for diabetes and obesity, as well as analgesic, antimicrobial, antioxidant, and GI activity. 

Traditional ethnic treatments have utilized the bark, kernels, leaves, or roots of the African Mango plant for thousands of years for a variety of ailments. 

Numerous studies exist on the potential industrial application of African mango in food, cosmetic, and pharmaceutical products.

L-carnitine is an amino acid derivative that transports fatty acids into your cells to be processed for energy. It is made by your body and also available as a supplement.

However, one analysis of nine studies — mostly in obese individuals or older adults — found that people lost an average of 2.9 pounds (1.3 kg) more weight while taking L-carnitine (2). 

While it may aid in weight loss for obese individuals or older adults, a thorough diet and exercise regimen must be in place first.

The active ingredient of Garcinia Cambogia is in the fruit's rind, hydroxycitric acid. 

Hydroxycitric acid, or HCA, appears to block an enzyme called citrate lyase, which your body uses to make fat. It also raises levels of the brain chemical serotonin, which may make you feel less hungry. 

Some research has found that garcinia cambogia may improve cholesterol levels, lowering triglycerides and LDL (the "bad" cholesterol) and raising HDL (the "good" cholesterol). 

Also known as Paullinia cupana, Guarana is a climbing plant prized for its fruit. 

 A mature guarana fruit is roughly the size of a coffee berry. Guarana extract is made by processing the seeds into a powder. Amazonian tribes have used guarana for centuries for its therapeutic properties and this may be because it contains an impressive range of stimulants, such as caffeine, theophylline and theobromine. Guarana also boasts antioxidants, such as tannins, saponins and catechins

Guarana contains caffeine, which may aid weight loss by boosting metabolism. It has also been found to suppress genes that aid fat cell production and promote genes that slow it down.
