Weight loss supplements are very popular, and their demand is also steadily on the rise nowadays. This is because many users believe the effectiveness of these weight loss supplements. The manufacturers of such supplements usually market their products by making claims about how they have the capabilities that can help the users in burning unwanted body fats and shedding off their extra pounds.
These capabilities are usually attributed to the ingredients which these companies utilize to formulate the products. These ingredients may include vitamins, minerals, enzymes, and, most especially, organic ingredients that the companies claim to have fat-burning properties. Weight loss products are combinations of several of these ingredients. Aside from that, the dosage of each ingredient also varies.
Since several ingredients are combined and their dosages vary, studies are not able to specifically point out what effects can each ingredient cause to the user. Also, the products are usually tested in animal and laboratory studies which limits the whole understanding to theories that the researchers can conclude. There are a couple of Slimfy ingredients that are commonly used in weight loss supplements and their purported effects to the user.
One of these most common ingredients is p-synephrine, or simply synephrine, which comes from the bitter orange plant or scientifically known as Citrus aurantium. Synephrine enables the body to spend more energy while suppressing the appetite of the user. This ingredient is a substitute for ephedra after the latter was banned for use due to its adverse side effects. This does not mean that it does not have side effects, though. Some people report anxiety, myocardial infraction, ischemic stroke, ventricular fibrillation, chest pains, and even death.
Caffeine is another common ingredient. While some might think that this is only present in coffee-based weight loss products, tea-based ones also have caffeine. This ingredient is responsible for the stimulation of the skeletal muscles, heart, and whole central nervous system. It also helps increase the activity in the colon. With regards to its side effects, the user may experience nervousness, shakiness, and sleep disturbances. If one takes higher doses of caffeine, the side effects may include vomiting, nausea, cerebral edema, seizures, and tachycardia. This is the reason why the addition of other ingredients to caffeine, especially bitter orange, can increase the power of these effects.
Another common ingredient is calcium, a mineral that supports the function and structure of the teeth and bones. Some studies propose that intakes of higher dosages of calcium can help users gain less weight over time. However, scientific and clinical trials show that this proposition is false, meaning high calcium intakes did not result in any change to the body, at all, regarding weight loss. Instead, they show that high calcium intakes can lead to constipation and interference with iron and zinc absorption. Calcium supplements in higher doses may also lead to higher risk of kidney stones.
One may also find the ingredient chitosan in a weight loss supplement. It is a polysaccharide that comes from the exoskeleton of a crustacean. Manufacturers claim that chitosan binds dietary fats inside the digestive tract, thus, promoting weight loss. However, clinical trials did not show significant weight loss contribution from this ingredient. As for the side effects, these may include bloating, indigestion, heartburn, constipation, and flatulence.
Green tea, known scientifically as Camellia sinensis, and green tea extract are also common ingredients. Many people believe these ingredients have numerous health benefits. These ingredients, according to some experts, promote weight loss through increasing fat oxidation and energy expenditure. With the clinical trials, such ingredients may have small effects on weight loss. No major side effects have been reported, though.
