The efficacy and safety of these ingredients might be different when they are combined with other ingredients in a product. African mango, or Irvingia gabonensisis a fruit-bearing tree that is native to western and central Africa [ 16 ].

Irvingia gabonensis seed kernel extract has been proposed to promote weight loss by inhibiting adipogenesis, as demonstrated in vitro [ 17 ].

In addition, a proprietary extract of Irvingia gabonensisIGOB, reduces serum levels of leptin [ 18 ], a hormone that is positively correlated with body weight and percentage body fat [ 19 ]. IGOB might also reduce total cholesterol and low-density lipoprotein LDL levels [ 18 ].

Studies have examined the effects of Irvingia gabonensis on weight loss to only a limited extent in humans. Participants who received the extract had significantly lower body weight, body fat, and waist circumference at the end of the trial than those taking a placebo.

This trial, along with two others, was included in a systematic review whose authors reported that Irvingia gabonensis extract causes statistically significant reductions in body weight and waist circumference [ 19 ].

The authors noted, however, that the trials included in the review used different study methodologies, small samples, short intervention periods, and varying daily doses of Irvingia gabonensis extract mg to 3, mg ; in addition, the trials were all conducted by the same authors.

Additional trials with larger samples and diverse populations are needed to determine whether Irvingia gabonensis extract is effective for weight loss [ 19 ]. Irvingia gabonensis extract appears to be well tolerated. Most reported adverse effects are mild, including headache, difficulty sleeping, flatulence, and gas [ 19 ].

However, Irvingia gabonensis has been associated with renal failure in a patient with chronic kidney disease [ 21 ]. Beta-glucans are glucose polysaccharides found in bacteria, yeasts, fungi, and cereal grains such as oats and barley.

As soluble dietary fibers, beta-glucans are proposed to increase satiety and gastrointestinal transit time and to slow glucose absorption [ 16 ]. Consumption of beta-glucans from barley has been shown to reduce energy intake and appetite in humans [ 22 ].

Several studies have investigated the effects of beta-glucans on blood lipids, blood pressure, and insulin resistance, with weight loss as a secondary outcome. In one of these studies, 66 women who were overweight followed a low-calorie diet designed to produce a 0.

At the end of the trial, all groups lost weight and had a smaller waist circumference, but there were no significant differences between groups. Beta-glucans appear to be well tolerated. Reported adverse effects include increased flatulence but not changes in stool consistency, stool frequency, or bloating [ 24 ].

Bitter orange is the common name for the botanical Citrus aurantium. The fruit of this plant is a source of p-synephrine often referred to simply as synephrine and other protoalkaloids [ 28 ]. As alpha-adrenergic agonists, synephrine alkaloids can mimic the action of epinephrine and norepinephrine.

However, the extent to which bitter orange and synephrine cause similar cardiovascular and central nervous system effects to epinephrine and norepinephrine e. Studies suggest that bitter orange increases energy expenditure and lipolysis and that it acts as a mild appetite suppressant [ 2527 ].

After FDA banned the use of ephedrine alkaloids in dietary supplements in [see section on ephedra má huáng ], manufacturers replaced ephedra with bitter orange in many products; thus, bitter orange became known as an ephedra substitute [ 29 ].

Although synephrine has some structural similarities to ephedrine, it has different pharmacological properties [ 2730 ]. Several small human studies have examined whether bitter orange is effective for weight loss [ 30 ]. Interpreting the results of these studies is complicated by the fact that bitter orange is almost always combined with other ingredients in weight-loss supplements.

At the end of the study, participants taking the combination bitter orange product had a significantly greater reduction in percent body fat and fat mass and a greater increase in basal metabolic rate than those in the placebo and control groups.

Participants in all groups lost weight, but the authors did not report whether the mean reduction in body weight in the treatment group 1. The peak rise in resting metabolic rate at baseline was significantly higher in participants taking the herbal supplement than those in the placebo group, but the difference was not significant at the end of the 8-week study.

Participants taking the herbal supplement had a significant increase in mean body weight 1. However, this increase in body weight did not significantly affect body fat and lean tissue levels or waist circumference.

The authors noted that the weight gain might have occurred by chance because the trial was insufficiently powered to detect this small difference. The authors of a review of 23 small human clinical studies involving a total of participants concluded that synephrine increases resting metabolic rate and energy expenditure [ 30 ].

According to all of these reviews, longer term clinical trials with rigorous designs and large samples are needed to determine the value of bitter orange for weight loss.

Products containing bitter orange may have significant safety concerns. Reported adverse effects include chest pain, headache, anxiety, elevated heart rate, musculoskeletal complaints, ventricular fibrillation, ischemic stroke, myocardial infarction, and death [ 3435 ].

However, many of the products with these effects contain multiple herbal ingredients, and the role of bitter orange in these adverse effects cannot be isolated. Some studies indicate that bitter orange and synephrine—as bitter orange extract or pure synephrine—raise blood pressure and heart rate, but other studies show that they do not have these effects [31].

Some researchers have suggested that synephrine might not act directly as a cardiovascular stimulant [ 273739 ]. Instead, caffeine, other stimulants in multicomponent formulations, and other constituents of bitter orange or adulterants such as m-synephrine, which is not naturally present in bitter orange might be responsible for its observed effects.

Many dietary supplements promoted for weight loss contain added caffeine or an herbal source—such as guarana Paullinia cupanakola or cola nut Cola nitidaand yerba maté Ilex paraguariensis —that naturally contains caffeine. Green tea and other forms of tea also contain caffeine see section on green tea.

Some weight-loss supplement labels do not declare the amount of caffeine in the product and only list the herbal ingredients. As a result, consumers might not be aware that the presence of certain herbs means that a product contains caffeine and possibly other stimulants [ 41 ].

Caffeine is a methylxanthine that stimulates the central nervous system, heart, and skeletal muscles. It also increases gastric and colonic activity and acts as a diuretic [ 4243 ]. Caffeine has a half-life of about 6 hours; blood levels increase within 15—45 minutes of consumption, and they peak at around 60 minutes [ 44 ].

Caffeine increases thermogenesis in a linear, dose-dependent fashion in humans [ 45 ]. A mg dose of caffeine, for example, increased energy expenditure by a mean of 9. Caffeine might also contribute to weight loss by increasing fat oxidation through sympathetic activation of the central nervous system and by increasing fluid loss [ 4145 ].

Habitual use of caffeine however, leads to caffeine tolerance and a diminishment of these effects [ 4143 ]. Caffeine increases energy expenditure and fat oxidation [ 44 ].

However, the extent to which these effects affect weight loss is less clear, partly because clinical trials examining the effects of caffeine on weight loss have all been short and have used combination products. After 6 months, those in the treatment group lost significantly more weight mean weight loss 5.

A product containing caffeine plus glucosyl hesperidin G-hesperidin, a flavonone glycoside found mainly in citrus fruits reduced abdominal fat and BMI in a clinical trial in Japan [ 47 ].

In this study, 75 healthy men and women who were overweight BMI 24—30 received one of five treatments daily for 12 weeks while maintaining their regular lifestyle and eating habits. The five treatments were placebo and four formulations of 0, 25, 50, or 75 mg caffeine plus mg G-hesperidin.

The 75 mg caffeine plus G-hesperidin significantly reduced BMI by a mean of 0. The 50 or 75 mg caffeine plus G-hesperidin also significantly reduced abdominal fat compared to placebo, whereas the G-hesperidin alone or with only 25 mg caffeine did not significantly affect BMI or abdominal fat.

Could one of these 7 prescription weight-loss pills be right for you?	Contrave® is delivered in the form of an oral tablet; at the maximum recommended dose, two tablets are administered twice daily. In Canada, it is approved for use alongside a reduced-calorie diet and increased physical activity in adult patients with:. GLP-1 or glucagon-like peptide-1 is a hormone that is found naturally in your body that has effects on appetite and food intake. Saxenda® is a GLP-1 therapy that is similar to the natural GLP-1 found in your body. Saxenda® is thought to help patients lose weight by decreasing appetite and the amount you eat. Studies with Saxenda® have also shown that it may also improve other health factors beyond weight, including waist circumference, blood sugar, blood pressure and cholesterol levels. Saxenda® comes in a prefilled pen that you can use to self-inject. In Canada, Saxenda® is indicated along with a reduced-calorie diet and increased physical activity for chronic weight management in adult patients with an initial body mass index BMI of:. In order for fats from foods you eat to be absorbed into the body, they need to be broken down by enzymes called lipases. When Xenical® is taken with meals, it prevents these enzymes from working and causes a decrease in the amount of fat your body absorbs from your food. When you absorb less fat, you take in fewer calories, leading to weight loss. Just about anyone who's tried it knows that losing weight is hard. When calorie restriction and cardio workouts leave you tired and hungry, anything that could hurry progress seems worth a try — especially something as easy as a pill. When it comes to diet pills, there are two types: prescription drugs, and over-the-counter supplements. And they are not created or regulated equally. The Food and Drug Administration has approved five prescription drugs for long-term weight loss based on research about their safety and effectiveness. Only three of them are pills:. A few other medications — most commonly phentermine — are approved for short-term use. But prescription weight loss medication isn't for everyone. These pills aren't a perfect solution for obesity. Weight loss medications are used along with a healthy diet and exercise regimen that need to be continued after treatment. Also, side effects are common and can be severe. There are many diet pills available that aren't FDA-approved or -regulated, and there is minimal evidence that they actually work. Since over-the-counter dietary supplements don't have to be vetted for safety or efficacy by the FDA , it's much easier to get them onto shelves and into your medicine cabinet. In fact, many manufacturers of weight loss supplements don't test their products in humans before taking them to market. What's more, the FDA has warned that some over-the-counter products contain hidden ingredients. These include prescription drugs and controlled substances like sibutramine , which was removed from the market in because it substantially increased heart rate and blood pressure. So if you're considering a diet pill supplement, there are a few things you might want to know first. These types of diet pills often contain vitamins, minerals, enzymes, and herbs. The most common ingredients can be found in a database from the National Institutes of Health. One such ingredient is Garcinia cambogia, which comes in products like Hydroxycut and Plexus Slim. It's supposed to suppress appetite and decrease the number of fat cells your body makes. Though it's considered "fairly safe," there's no evidence that it actually helps with weight loss, and excessive use has been linked to liver problems. Other diet pills may contain chitosan, from the shells of crabs, lobsters, and shrimp. In theory, it's supposed to bind fat in your digestive tract so your body can't absorb it. Make sure you talk to your healthcare provider about taking a multivitamin supplement. Wegovy is the newest FDA-approved weight-loss medication and works much the same way as Saxenda, by mimicking the action of the hormone GLP-1 to suppress hunger. Wegovy is a once-a-week injectable. Dosage is increased over the course of several weeks-to-months, until a 2. In one study , the mean change in body weight was Like Saxenda, Wegovy carries a black box warning due to the possibility that it may increase your risk of certain thyroid tumors and cancer. Pancreatitis, gallbladder disease, kidney injury, low blood sugar, and other conditions have also been reported with Wegovy use. While most side effects are mild, some can be very serious and will vary based on the drug and the person using it. Umashanker explains. If you decide to stop taking the drug for any reason, speak to your doctor about how to do so safely. Quitting cold turkey can be dangerous with some of these drugs. And now for the million dollar question: Given the choices, which are the best diet pills based on safety and effectiveness? Kanji notes. For example, a person with a history of pancreatitis would want to avoid Wegovy and Saxenda but may be fine with Qsymia. On the other hand, a person with a history of kidney stones may want to avoid Qsymia. Some tips to help you get to a healthy weight? And steer clear of any pill or herbal remedy that claims to be the best weight-loss supplement such as:. Even natural ingredients at certain levels can be toxic to some people.
