Hives, itching and rash may also occur. If any of these symptoms appear, call your doctor immediately. Read more: The Most Effective Diet Pills. Do weight-loss pills work? The options on the market today aren't very effective, says UC Davis Health.

They help some people in the short run, but the weight tends to come back. In addition, no single drug helps everyone. A more important question is whether weight-loss pills are safe. The Food and Drug Administration has serious concerns. It reports that hundreds of "miracle" weight-loss pills and products contain ingredients that either haven't been studied on humans or have been banned due to safety issues.

Weight-loss pills are also tainted with ingredients from approved medications used to treat an array of disorders. These include drugs for seizures, high blood pressure and depression, along with diuretics, which can have serious side effects, reports the FDA.

Hidden, potentially harmful ingredients are also found in "natural" weight-loss supplements , notes the FDA.

The law doesn't require such products to obtain FDA approval before they're put on the market. Dangers associated with them include heart palpitations, high blood pressure, stroke, seizures and death.

Some ingredients in diet pills pose a greater health risk than others. Ephedra, sometimes called ephedrine or ma huang, is a banned stimulant that causes an irregular heart rate, high blood pressure, mood changes, heart attacks, strokes and seizures, says the Mayo Clinic. Bitter orange is an herbal stimulant that is used in some diet pills as a substitute for ephedra, yet it isn't safe because its actions are similar.

Phenylpropanolamine, or PPA, was once used in decongestants: When combined with other decongestants, it can elevate blood pressure and cause a stroke, states UC Davis Health.

Aside from stimulants and decongestants, beware of dietary teas that work as laxatives, cautions UC Davis Health. They can produce pain and constipation over time. Because of the extreme dangers of some weight-loss pills, research them carefully before purchasing.

The Mayo Clinic recommends looking for information on any that you are considering at the Office of Dietary Supplements and the National Center for Complementary and Integrative Health, a database for dietary supplements.

Check with your doctor prior to adding a weight-loss pill to your daily regimen. The FDA says to be on the alert for warning signs of tainted products.

These include products marketed in a foreign language or touted to be alternatives to FDA-approved drugs. Be wary of guarantees or unrealistic promises that you'll "lose 10 pounds in a week. Sustained weight loss can be difficult, so it's tempting to look for a quick fix or to try products with inflated claims.

The American College of Cardiology offers a simple formula: Burn more energy than you consume from food. A reduction of 3, calories will result in a loss of 1 pound. With this in mind, if you reduce your food intake by a mere calories per day, you'll lose 10 pounds within a year.

Gimmicky diets are restrictive, which makes long-term adherence challenging and presents the potential for nutrient deficiencies. Conversely, the Mediterranean diet involves eating a broad variety of nutrient-dense foods that promote health.

Foods that comprise the diet include fruit, vegetables, nuts, whole grains, olive oil and fatty fish. Read more: Why the Mediterranean Diet Is Ranked the Best for Studies link the Mediterranean diet to several health benefits, including weight loss.

Additionally, the company does not provide a supplement facts label or the dosage of all active ingredients for its MetaboUP Plus product.

Though diet supplements like Lipozene may seem appealing, they should not be considered a replacement for a well-rounded diet and healthy lifestyle to support long-term, sustainable weight loss.

Furthermore, Lipozene may not be suitable for everyone. You should discuss any concerns or adverse side effects that you experience with your doctor and should use supplements only as directed. Working with a healthcare professional, such as a registered dietitian RD , to develop a personalized plan may also be beneficial to help you reach your weight loss goals.

This is because Lipozene contains glucomannan, a type of fiber that has been shown to reduce constipation, increase the frequency of bowel movements, and possibly cause diarrhea 14 , The active ingredient in Lipozene is glucomannan, a type of dietary fiber derived from the roots of the konjac plant 1.

Some studies suggest that glucomannan, the active ingredient in Lipozene, could potentially support short-term weight loss. However, the research is mixed 9 , Additionally, there is limited research on the long-term effectiveness of Lipozene, and it should not be used as a replacement for a balanced diet and active lifestyle.

While some studies suggest that the glucomannan in Lipozene could help you reach your weight loss goal, others have shown no benefit. Our experts continually monitor the health and wellness space, and we update our articles when new information becomes available.

This eliminates the need to worry about negative side effects such as anxiety, jitters and trouble sleeping, which are commonly experienced when using high-stim fat burner supplements.

Regarding the ingredients, Clean Burn is a combination of Carnipure, green tea leaf extract, GS4 Plus and Capsimax, along with the mineral chromium in the form of chromium picolinate. In my opinion, this is a well-formulated product because all of these ingredients have shown potential weight loss benefits, especially when taken in the correct dosages.

For example, Carnipure L-carnitine L-tartrate in doses of 2, milligrams per day has been shown to provide a modest reduction in body weight, fat mass and BMI, especially in overweight individuals That said, if you plan on using Clean Burn as recommended, this will provide 3, milligrams per day, which may cause side effects such as nausea, vomiting, abdominal cramps, diarrhea and a fishy body odor Another key ingredient is the green tea extract—dosed at milligrams per serving—close to 1, milligrams per day.

At these dosage levels, studies have shown significant weight loss results, along with a decrease in total cholesterol levels without any side effects The final ingredient I want to mention is the chromium picolinate.

While the research suggests that chromium may play a role in carbohydrate, lipid and protein metabolism, more studies need to be done to determine how this actually takes place.

I want to talk about this mineral because the dosage level of micrograms per serving far exceeds the adequate intake level of 35 micrograms per day for men and 45 micrograms per day for women. While some studies have used dosage levels of up to 1, micrograms of chromium per day, some adverse effects at these higher concentrations have been reported.

Chromium also has the potential to interact with certain medications taken for diabetes, such as insulin and metformin This is why we highly recommend that you consult with a primary healthcare provider before taking Kaged Clean Burn to ensure your safety. Kaged Clean Burn uses five ingredients that the company says work together to help you burn fat, boost metabolism and manage your weight without using stimulants.

Our reason for classifying it as the best thermogenic fat burner is that there is some science to support the list of ingredients in the product, including chromium for blood glucose control 29 , green tea extract for fat metabolism 13 , capsaicinoids for potential thermogenic properties 26 and L-carnitine which may support body weight reduction Currently, it is rated 4.

It is third-party tested and certified drug-free by the BSCG. Related Post: The Best Teas for Losing Weight and Boosting Your Metabolism. PhenQ PM's lack of caffeine and stimulants makes it an obvious choice for a nighttime fat burner.

PhenQ claims that the formula's amino acid content can also promote better sleep and support nighttime fat burning. Each four-capsule serving contains a total amino acid dosage of 2, milligrams—1, milligrams apiece of L-lysine and L-arginine, plus milligrams of L-theanine and milligrams of 5-HTP.

Judging PhenQ PM by customer reviews is difficult since the page for this specific product on the PhenQ website currently has just one testimonial. You can read our full assessment of this product in our PhenQ PM review. Both chromium picolinate and acetyl-L-carnitine also provide a potential fat loss benefit, with chromium playing a key role in fat metabolism 62 and L-carnitine supplementation demonstrating modest reduction effects in body weight, body mass index BMI and total fat mass in numerous studies.

Transparent Labs Lean uses ingredients and dosing specifically targeted at improving endurance and converting fats to energy during workouts. Like other Transparent Labs products, it's third-party tested. It currently has a 4.

The reason why we chose it as the pre-workout fat burner is because of its BCAA, beta-alanine and betaine contents—all of which have been shown to positively affect stamina during weight training and endurance exercise 64 Related Post: The Best Pre-Workout Supplements on the Market, According to a Nutrition Coach.

Based on this ingredients list, this product is designed to help individuals convert stored body fat into usable energy. That being said, aside from the caffeine which is dosed at milligrams per two-capsule serving size, I would like to see more acetyl L-carnitine and green tea extract in this product.

The current scientific literature supports a 2-gram per day serving of L-carnitine and greater than milligrams per day of green tea extract to support your weight loss goals. Jacked Factory Burn XT is a simple formula that has only five active ingredients: acetyl-L-carnitine HCL, green tea leaf extract, caffeine anhydrous, Capsimax cayenne pepper extract and BioPerine black pepper extract.

We've already touched on many of the ingredients typically found in the best weight loss supplements that focus on fat-burning, including green tea, Capsimax powder, B vitamins and caffeine.

Other common ingredients in thermogenic supplements include:. Related Post: Apple Cider Vinegar for Weight Loss. First, the ingredients provided by supplements are typically based on dosages that have been researched for safety and efficacy.

Second, individuals may develop a tolerance to several ingredients found in thermogenic supplements—meaning that they become less effective. Certain studies indicate that this may ring true regarding the arousal effects of caffeine and yohimbine, and the thermogenic effects of active ingredients in green tea extract For those new to thermogenic supplements, a more conservative approach is to start with a small dose ex: a quarter or half of a recommended serving and gradually increase the dosage to test your tolerance, but never exceed the recommended dosage.

If you experience unwanted side effects, stop using the product altogether. It's important to stay well hydrated while using a thermogenic fat burner supplement. Along with a balanced diet, regular physical activity and good sleep, drinking plenty of water can effectively aid in weight loss. Related Post: Does Drinking Water Help You Lose Weight?

Finished dietary supplements, like those used for fat-burning and weight loss, are regulated by the FDA under the Dietary Supplement Health and Education Act DSHEA of However, the vastness of the supplement industry may result in some products entering the market before full evaluation, so consumers should exercise caution and seek professional advice when considering supplements.

Even if a substance has not been banned by the FDA, it may still cause unwanted side effects. These are some of the main precautions for thermogenic ingredients:. Many supplements used for fat burning contain herbs or other ingredients found in plants.

For example, the natural herb ephedra is banned by the FDA because it was linked to serious side effects such as heart attack, seizure, stroke and sudden death DMAA is also not generally recognized as being safe Thermogenic supplements that contain stimulants e.

caffeine can cause flushing, increased heart rate, nausea, dizziness, headaches and heart palpitations. They can also stimulate the cardiovascular system in a manner that could raise blood pressure.

Thus, those with pre-existing cardiovascular risks such as hypertensive individuals should not consume these supplements. Pregnant women, women who are breastfeeding, underaged consumers, persons with certain medical issues e.

Talk to your surgeon far in advance of the operation and inform them of every dietary supplement that you're taking. And finally, thermogenic supplements without modifying the diet or engaging in routine exercise have very limited effects.

Hence, these supplements should be viewed as an accessory, rather than the key, to a successful and sustainable weight loss goal. In general, you should always consult your healthcare provider before taking nutritional supplements, and this holds true for supplements used while trying to burn fat.

Thermogenic fat burner supplements are not for everyone. Proceed with caution and patience when choosing the best thermogenic supplement for your weight loss goals.

Finding the optimal balance of safety and effectiveness can take time, as there are dozens of options to choose from. You can simplify your decision by looking at the active ingredients, dosage, form and cost. An active ingredient list is the most important factor to consider when choosing the best fat burner supplement for you.

For the best results, start with a small dose to check your tolerance and gradually increase the dosage until you reach the recommendation for daily use. Never exceed the recommended daily dosage, and always check with your physician or a registered dietitian nutritionist first.

Thermogenic supplements typically come in pill or powder form. Pills are typically swallowed and taken with a glass of water. Powdered supplements in general are mixed into water or a sports drink and taken with a meal or snack.

Some may be suitable to consume on an empty stomach. Stick to your budget, and remember to optimize your diet, physical activity and sleep—a supplement is just the cherry on top of your weight management efforts.

Among them are:. Learn more about our product review process and supplements rating methodology. Taking fat burners and other types of diet pills can be safe as long as you do it responsibly.

The first requirement is that you check with your healthcare provider before taking them, as you would with any type of supplement. Fat burners could pose a risk to your health depending on your medical history, your current health status and whether you're taking medications that might cause an interaction.

Also, people with a history of eating disorders should not take weight loss pills. The second step of responsible use is to follow the manufacturer's recommendations for how and how often to use the supplement. Even for healthy individuals, fat burners and other types of over-the-counter weight loss pills could cause health issues if consumed in excess of the recommended dosage.

Fat burners typically work by stimulating a thermogenic response in your body, thereby increasing your resting metabolic rate RMR. Some contain stimulants like caffeine to provide an energy boost during your workout, which may help you burn more calories.

They may also decrease your appetite, though the study results do not always show promise. Related Post: Do Weight Loss Pills Work? Maybe, but it depends largely on the fat burner's formula, the recommended dosage and your health status.

Some fat burners contain only water-soluble ingredients that are generally safe to consume every day. I started taking these sometime at the beginning of the year. I had my thyroid removed back in Dec and I gained almost 40 lbs. So a lot of the extra pounds are on my belly area and I thought I prayed these would help.

The positive of these awesome lil pills is that I sleep like a baby!!! I used to take prescription meds for sleep my entire adult life and I stopped a couple of years back , so I had just been sleeping normally and waking up feeling tired.

Then I started taking these!!! I will not stop them because of how energized I feel in the am. I wake up feeling incredible and without an appetite, I do have to make myself drink a shake in the AM to start of my day!!!

I was excited! But then I not only did not continue to lose weight, I gained weight. But I must be honest, I haven't done much to change my diet, so I can't totally blame the product now can I?

However, I have noticed that even I'm no longer losing weight, I do seem to be trimming down. Nothing significant yet, but I have noticed a slight difference in my waistline. I've ordered another bottle and will continue taking the product for another month or two in order to give it a fair chance.

Prior to taking this supplement I was lucky to get 2 hrs of deep sleep. Now I'm getting hrs, which for me is pretty good. I have not noticed any problems after taking the supplements. No highs and lows, no racing heartbeat, or intestinal problems.

I'll do another review after taking the product for another month. Great product 👌. I used this to lose weight and stop my night snacking. I like to snack later at night then I should. So I tried using the night time fat burner. So far this has helped me from not want to snack late at night and I have lost a few pounds!!

I would recommend this product to anyone that is trying to get over late night cravings to wanting to lose a little weight. It really works!! Images in this review. Didn't affect my sleep quality in a negative way. But I also don't think that it actually did anything for me.

You don't actually need that extra help at night. Just let your body rest. I used for about three months didn't notice any real difference. I dunno wts the benefit?! Just if u wanna sleep take it. I will try it again.
