Are Weight Loss Supplements Safe?
The FDA regulates supplements, but these products do not undergo a premarket review. Rather, supplement manufacturers determine the safety and validity of their products.
When a supplement turns out to be unsafe, the FDA will remove it from the shelves and force the manufacturer to implement a product recall.
Additionally, the FDA has the authority to act against supplement makers who invent unproven claims.
Although many weight loss supplements include caffeine, there is no scientific evidence that suggests caffeine is a miracle supplement.
Caffeine stimulates the central nervous system, temporarily increasing alertness.
This stimulant is the most widely consumed legal psychoactive agent in the country, but its benefits are far less than its side effects.
However, caffeine can help you lose weight and maintain a healthy lifestyle.
Read on to find out how caffeine can help you lose weight and avoid its drawbacks.
Despite its potential weight loss benefits, research has found that caffeine may cause negative energy balance in the body.
It also increases the body’s metabolism, possibly by 4% or 5%. Caffeine may also increase appetite, making it harder to resist a meal.
While caffeine has proven to be a successful weight loss supplement, it’s important to remember that the effects of the ingredient are still far from certain.
It’s best to stick to natural sources of caffeine to get the most health benefits.
A recent study suggests that the use of fluoxetine may cause weight gain in some people.
However, the study did not investigate whether weight gain is related to the drug’s long-term use.
In a study in which patients with acute treatment of depression were randomly assigned to fluoxetine or a placebo, weights were measured after the treatment.
In this study, patients were given a one-week supply of fluoxetine or a placebo, and their weights were recorded again after the two weeks had elapsed.
The drug fluoxetine belongs to the class of selective serotonin reuptake inhibitors or SSRIs.
These drugs increase serotonin levels in the brain and are prescribed for bulimia, depression, obsessive-compulsive disorder, and panic attacks.
But Prozac can cause weight gain, and it has been associated with an increased risk of ventricular arrhythmia.
Patients are strongly advised to contact their doctor if their symptoms worsen.
While many people think phenolphthalein is a safe weight loss ingredient, there are some safety concerns surrounding the use of this chemical.
The chemical, sibutramine, was pulled from the market in 2010 because of its association with an increased risk of heart attack and stroke. It has also been linked to cancer.
In fact, more than 50 reports of problems with tainted bee pollen products have been received by the FDA. Users reported experiencing serious health problems, including chest pain, increased heart rate, elevated blood pressure, and a host of other conditions.
People with heart conditions should avoid using weight loss products containing phenolphthalein. Many online retailers sell a product with a misleading labels.
The company markets the product as a 100% herbal, new slimming pill.
This product contains phenolphthalein, which is listed on the FDA’s public notification page as a suspected carcinogen.
In addition, sibutramine, the active pharmaceutical ingredient in the brand-name diet drug Meridia, has been linked to cancer.
Clinical trials have shown that sibutramine is safe for use.
There were no significant adverse effects of the supplement on blood pressure, lipid profiles, or uric acid levels. However, sibutramine has been linked to increased blood pressure and pulse rat
. The increases were less severe in those patients who had lost weight and were not hypertensive.
This suggests that sibutramine may be safe for use in obese patients.
The European Medicines Agency reviewed the medication twice and concluded that the risks were outweighed by its benefits.
However, in 2010, the agency suspended the product’s license in the European Union.
Because of the potential side effects, such as elevated blood pressure and heart attack risks, the drug was withdrawn from sale in the European Union and a number of other countries.
As such, it is important to discuss with your doctor the benefits and risks of sibutramine before you start using it.
