You’ll find some of these popular weight loss pill ingredients in these weight loss pills above. But what does science have to say?
- Guarana
- Caffeine
- Yerba mate
- Capsimax powder
- Chromium picolinate
- L-carnitine fumarate
- Green coffee bean
- Glucomannan
- Cayenne pepper seeds
Guarana is a flowering plant, native to the Amazon region. It contains caffeine and is used to treat hypertension. Guarana may also have a positive effect on energy expenditure and metabolism, further benefitting obese individuals [7].
Caffeine functions as a stimulant and appetite suppressant, which is why you’ll often find this ingredient in weight loss pills and diet capsules. While studies don’t fully back the hypothesis, caffeine is shown to cause a minor impact over short spurts during the day [8].
Yerba mate is another plant here that’s native to South America. Many people have used it for medicinal purposes where it can supposedly increase focus, physical performance and energy levels. Yerba mate may also support the metabolism process.
Capsimax powder comes from capiscum, or the red pepper plant. This vegetable works to promote heat, aiding in the digestion and metabolic processes. Unfortunately, studies are not conclusive at this time.
Chromium picolinate may help in building muscle mass, as it’s essential for protein synthesis. Chromium may also play a positive role in digestion. It might also improve body composition and help with fat loss [9].
L-carnitine fumarate is an amino acid which helps the body utilize fat effectively. This indicates that it also supports metabolic processes, supporting weight loss as it helps convert fat into energy. L-carnitine fumarate also aids in brain function and muscle movement.
Green coffee bean comes in as another form of caffeine used in weight loss pills. It comes from raw coffee beans, before they’re roasted.
The reason for its popularity boils down to the chlorogenic acids inside the beans. These acids are antioxidants that also have an anti-inflammatory effect on the body. Several studies note the potential for green coffee beans to enhance weight loss efforts, though evidence isn’t definitive at this time.
Glucomannan comes from the Konjac plant, specifically the plant’s fiber-filled root system. It works to promote heart health and a robust digestive system [10].
Cayenne pepper seeds are a type of chili pepper that warms the body through thermogenesis and aids in digestion. Cayenne pepper may also speed up metabolism and curb your appetite, a necessary component to weight loss.
