You’re about to learn everything you need to know about Metabolife. We felt this one deserved an in-depth look at the ingredients, side effects, scientific studies and customer-service quality. Additionally, we examined hundreds of user reviews and comments. Then, we summarized and condensed the info to give you the facts you need.

Metabolife Readers: Click here to find out why we're giving away samples of our product, Dietspotlight Burn.

What is Metabolife?

Firstly, Metabolife ingredients are ingredients include guarana seed, Asian ginseng, green tea, yerba mate, eleuthero extract, whey protein concentrate, garcinia cambogia, caffeine, vitamins and minerals, among others. The company promotes weight-loss by concentrating on boosting energy levels, suppressing appetite and burning fat. Directions for use vary by supplement.

Metabolife has been around since 1995, although the company is now operated by Twinlab. The available supplements, including Extreme Energy, Weight Management Shake and Ultra Advanced Weight-Loss Formula are available on the official website and through trusted retailers. One positive is the longevity of the brand name and that we found some positive comments, but read on…

Fad Ingredients – “Connected to Weight-Loss?”

The first negative was Metabolife ingredients not being connected to weight-loss. “The company uses garcinia cambogia in multiple supplements,” said our Research Editor. “Although it’s a natural extract, there’s no research connecting it to weight-loss.”

One customer reported, “Didn’t lose any weight after using the product for 3 months. Very disappointing.”

Then again, a different user stated, “I find it helps with my energy and curbs my appetite.”

“Didn’t do anything for me as an appetite suppressant. It did give me energy though,” commented another.

Metabolife Side Effects – “Not Good!”

Another concern we have is Metabolife side effects. There are some customer reports of jitteriness, headache, loose stool, nausea and stomach discomfort. In fact, one user revealed, “Gives me serious diarrhea. It’s just not worth it.”

However, not all customers experienced side effects with Metabolife products. One person stated, “Upset my stomach a bit at first, but overall, it’s pretty good.”

Another said this, “Gave me quite a bit of energy, but no miracle pill. Darn it.”

Our research has shown if there is a specific aspect of a weight-loss formula that’s especially concerning, like being the cause of adverse reactions, long-term success is greatly impacted. This means if Metabolife supplements do in fact lead to unpleasant effects in a lot of customers, this could be a serious problem.

The Science – “Backed by Research?”

We appreciate that some Metabolife supplements do contain green tea and caffeine. These ingredients have been shown to help boost metabolism and increase energy levels. But, the benefits of those aren’t connected to weight-loss. Also, we couldn’t pinpoint any clinical research to back up claims made by the company. This is concerning, because we at DietSpotlight prefer to see some actual science used as evidence. When there’s nothing available, we raise the red flag.

The Bottom Line – Does Metabolife Work?

So, should you run out and buy a Metabolife supplement? Well, we like that all of these products are easy to find online and some natural herbs, but we have some reservations about this company because there’s no solid clinical research used to connect the supplements to weight-loss. Furthermore, we’re concerned about the unpleasant side effects some users experience. Not to mention, the fad ingredients that are used that didn’t produce results.

You want to lose weight and we’re here to help. That’s why we suggest going with a diet product that doesn’t rely on fad ingredients, is backed by solid science and does not lead to any harmful side effects.

Among the best products we’ve seen this year is one called Dietspotlight Burn. Its formula is a unique blend of four key ingredients that have been clinically-tested and have been shown to help ignite metabolism and improve fat loss. We can’t find any discouraging talk or user complaints, and customer feedback posted online reveals people are seeing substantial results.

The makers of Dietspotlight Burn are so confident in their product they’re offering a Special Trial Offer, which is very encouraging.

What You Should Know About Metabolife

Metabolife is a weight loss program designed with two steps. The company claims that they offer a couple of methods to lose weight and keep it off. They suggest that an individual can lose weight and maintain this loss through the Metabolife program. The two-step process contains three weight loss products and two weight management items. In the stage one process, a person can choose Metabolife Ultra, Metabolife Green Tea and Metabolife Caffeine Free. The stage two (weight loss maintenance) products are Metabolife Breakthrough and Metabolife Extreme Energy. The Metabolife manufacturers claim that the products are safe and effective for an individual. However, some warnings may apply. It is always a good idea to check labels before using any diet supplement products. You can find two of their products online: Extreme Energy Stage 2 Weight Management Support and Ultra Advanced Weight Loss.

An individual can locate helpful information regarding the Metabolife products from their official website. This will allow a person to find facts about weight loss and the best method to achieve their goal.

  • Seeing results with this product seems to require a serious exercise regimen as well.

Metabolife Conclusion

The Metabolife manufacturers claim that this two-step process is the best method to losing weight. They also suggest that each type of product they have to offer well help in losing excess weight and maintaining desired weight. An individual can locate helpful tips from their website on being successful during this trying period. Nevertheless, the Metabolife products cannot be purchased on their website, no clinical data has been posted and no testimonials can be found on the manufacturer's site. We would like to see some testimonials and a money-back guarantee to show that the manufacturer of Metabolife really believes in this product.

Guarana Seed

Sometimes called Brazilian cocoa or paullinia cupana, guarana seed is taken from a tree that grows in South America. This extract is used in a number of energy drinks, diet pills and weight-loss supplements.

What is it Supposed to Do?

Guarana seed contains a significant amount of caffeine, which is a stimulant and diuretic. Caffeine may help improve alertness, boost energy levels and elevate metabolism.

Clinical Research

WebMD states that, “Guarana might promote weight-loss when used in combination with mate and damiana.”

As you may be aware, clinical testing is an important factor to consider when it comes to choosing a weight-loss supplement or diet formula. Therefore one product you may want to take a look at is Dietspotlight Burn. It provides key ingredients that have been scientifically researched.

Asian Ginseng

Also known as panax or Korean ginseng, this herb is sometimes used to treat memory loss, low stamina and even Alzheimer’s disease. Asian ginseng contains panaxosides and ginsenosides. Aside from being used in a variety of diet pills and energy drinks, it’s also found in some cosmetics and soaps.

What is it Supposed to Do?

Often Asian ginseng is used in weight-loss supplements in order to help boost alertness, improve physical endurance, lower stress levels, and even aid the metabolism.

Clinical Research

“The reason Korean ginseng may help stimulate weight-loss is because it affects the way your body metabolizes carbohydrates,” reports Dr. Robert B. Saper and colleagues from Harvard Medical School, in a November 2004 issue of the American Family Physician. “In addition, loss of appetite occurs as a side effect of the herb in some users.”

Yerba Mate

Yerba mate is a plant that grows in South America. In fact, it’s commonly consumed as a beverage in places like Brazil. The leaves of this plant are sometimes used to make traditional medicine. Furthermore, this ingredient is found in a number of over-the-counter diet pills.

What is it Supposed to Do?

This herb contains caffeine, as well as other chemicals to help stimulate the heart, muscles and brain. It may help improve mood, boost energy levels, increase alertness and stimulate metabolism.

Clinical Research

According to MayoClinic.org, “Proponents of yerba mate say that it can relieve fatigue, promote weight-loss, ease depression, and help treat headaches and various other conditions. There’s no definitive evidence that these claims are valid.”

Is There Anything Out There That We Think TRULY Works?

There is one diet supplement that fits the bill. Dietspotlight Burn, which is made with unique ingredients that HAVE been clinically tested, may be a good choice. All customers can take total advantage of the Special Trial Offer, currently available. Click here to give it a go right now.

Metabolife Side Effects:

Some users of Metabolife report side effects. This doesn’t mean that you’ll necessarily experience problems, but it is wise to consider all risks before using this product.


When you have a case of “the jitters,” you tremble and shake spontaneously. You don’t know why, but you shiver as though you were cold. However, your body temperature and health are otherwise normal. Along with the trembling, you may feel nervous and anxious. The jittering goes away for a little while but then comes back.

What causes jittering?

Jittering is usually the result of consuming too much caffeine. And it’s not only beverages like coffee or tea. Many supplements have extremely high caffeine content. Jittering is also caused by stress. Taking measures to reduce the stress in your life can help alleviate the jitters.


Headaches can range from a level of mild discomfort to very acute pain. It’s a sharp tightness or pressure in your head that’s extremely uncomfortable. When a headache becomes severe, it can cause dizziness, loss of balance, and light-headedness.

What causes headaches?

Many illnesses cause headaches, including high blood pressure, glaucoma, ear infection, and stroke. [1] Most headaches are a result of everyday stressors. For instance, skipping meals and not getting enough sleep at night can make your head hurt.

Stomach Pain

Stomach pain can be very excruciating. Often, the stomach ache is accompanied by bloating, sweating, and malaise. You may even have a bad case of nausea.

What causes stomach pain?

Indigestion is one of the top causes of stomach pain. It might be you eat something that doesn’t agree with your stomach. This can be due to food intolerance or allergy. Always make sure to properly wash food. Make sure it isn’t spoiled. Other causes of stomach pain include kidney stones, stomach virus, and pelvic inflammatory disease.


When you have diarrhea, you run to the bathroom every few minutes. Your stool is watery and liquid. It’s not uncommon for diarrhea to be accompanied by bloating, gas, and stomach pain.

What causes diarrhea?

Diarrhea is a symptom of many conditions, including irritable bowel syndrome, viruses, and parasites. [2] Because diarrhea eliminates a lot of your bodily fluid, it can leave you dehydrated. Drink up if you have diarrhea! Metabolife has caused discomforting side effects for some users. If you experience adverse effects, cease use immediately. If you’re unsure how you might react to the ingredients in this supplement, ask your doctor for advice.




Metabolife is an herbal dietary supplement that was created in the late 1990’s. The first formula was linked to adverse events, but side effects from the reformulated versions are rare. Although limited, we did find customers who did experience some type of reaction.

I bought Metabolife extreme energy stage 2 about two years ago, do you still distribute this product?

Maribel (Editor)

Hi Gill! For detailed product and usage instructions, please refer to the Metabolife official website for more information.


I like the older metabolife. Was it metabolife extreme 2? Don’t remember exactly. I took extreme 2 several years ago till it was discontinued, really worked for me. I wish i could still buy that product. Don’t see anymore at the store

Delores hill

I used the original product back in 1998 I bought it in the mall,I was age 39 at the time….I was starting to gain weight at the time. I was always about size 10 but I never really ate a lot I was working two jobs and had no energy. With this product I fell in love with it. The box it came in explained how to use it. It also said to drink a lot of fluid eating the morning,afternoon and evening that’s what I did….. Also I didn’t like the way it made me feel, it made me jittery if I took 4 a day the way it’s prescribed, I couldn’t handle that so I took two a day one at 4:30 IN THE MORNING WITH WATER that would keep me going til noon then I would take the second one about 12:30 or 1:00 before 2:00 and that would keep me going till about 9 or 9:30 I would walk about 45 minutes at night just to burn off any energy left over eat something shower go right to sleep by ten thirty. Did I loose any weight yeas I did went down to a size 4 I didn’t take it on weekends and I would take a brake from it every six months it curves your appetite but since you have to ear with it you eat a lot less ……the only side effects I had was a dry mouth so I was always drinking water and juice. I took it of and on for three years it kept the weight off till about 2010 when I turned fifty I’m now fifty eight and I’m looking for it again only this time I will only take one a day you Loos weight and burn fat so maybe because I walked I had no excess skin are anything.

  helps with my sugar problem
Marie (Verified User)

I cut it in half and only take it twice daily; once in the morning with 8 oz. of water and again around lunch time. It gives me the needed energy, and has worked to help me keep the pounds off. If nothing else, it gives me that boost I need, and my doctor approved it; just said not to take in the evenings or it would keep me up. It also helps with my sugar problem because of the chromium.

Thuy Metheney

You actually make it seem so easy with your presentation but I find this topic to be really something which I think I would never understand. It seems too complicated and very broad for me. I’m looking forward for your next post, I will try to get the hang of it!

   I really like the product
Jane Benski (Verified User)

I am a bikini competeator and I needed to cut weight. I lost fat weight and gained muscle. I didn’t have any problems with Metabilife Ultra. I do follow a strict diet and workout for a hour to two hours a day also. I reallylike the product.

April Gholston

I took Metabolife one time. Thats all it took for me to realize this medicine was not for me. It made my heart race and made me feel very uncomfortable.

YTammy Ingramcontent://media/external/file/24628our Name

I was going to try it. But I thought I would see how it was for other people. So I guess I will try it.
