What is AdvoCare ThermoPlus?

ThermoPlus is a plant-based, botanical vitamin and herbal weight-loss supplement. It stimulates metabolism, manages appetite and enhances weight loss results. ThermoPlus contains some powerful fat-burners and appetite suppressants.

About AdvoCare Supplements

Advocare International, L.P. is a multi-level marketing company that was started in 1993. It’s based in Plano, TX, and offers an array of supplements for health and wellness, weight management, workouts, energy and focus, digestive support, muscle building and core nutrition. If you’re looking for the best Advocare products, here are some of the other supplements they offer:


AdvoCare ThermoPlus – How Many Times a Day?

If you’re asking yourself “Can I take ThermoPlus twice a day?” there’s no need. The directions say to take this diet supplement once daily, 30 minutes before a meal.


The instructions on how to use Thermo Plus are printed on the bottle’s label.

Is ThermoPlus Medical Weight Loss?

No, ThermoPlus is not a medical-grade weight loss option or prescription drug for treating obesity. It is an over-the-counter herbal supplement that aims to help you lose weight when it’s combined with regular diet and exercise.

There are no scientific studies posted on the official Advocare website explicitly supporting ThermoPlus capsules.


ThermoPlus Ingredients

Here is a closer look at the key ingredients found in ThermoPlus pills, and any research that supports them.

Oolong tea

A traditional Chinese tea that is partially fermented and contains caffeine. It’s often consumed as a hot beverage and is said to boost mental alertness, energy levels, focus, and even weight loss results.

LiveStrong reports, “Consuming oolong tea for six weeks helped participants in a study published in the Chinese Journal of Integrative Medicine in February 2009 to decrease both their weight and their body fat.” [1]

WebMD says, “Drinking oolong tea or other caffeinated beverages throughout the day seems to maintain alertness and mental performance.” [2]

Sage leaf

An herb used to season foods and make some traditional medicine. It is often said to improve memory, enhance mental performance and boost alertness.

WebMD tells us, “Taking a single dose of common sage (Salvia officinalis) or Spanish sage (Salvia lavandulaefolia) by mouth seems to improve memory, alertness, and attention in healthy adults. When used as aromatherapy, these sage species seem to improve alertness, but not attention and memory.” [3]

A study in the Journal of Traditional and Complementary Medicine says, “Some chemical compounds like flavonoids, terpenoids, and essential oils are present in different species of Salvia (sage). Studies suggest that Salvia species, in addition to treating minor common illnesses, might potentially provide novel natural treatments for the relief or cure of many serious and life-threatening diseases such as depression, dementia, obesity, diabetes, lupus, heart disease, and cancer.” [4]


Also called Paullinia Cupana or Brazilian cocoa, this plant grows in regions like Brazil. It contains the stimulant caffeine, and is sometimes used to increase energy, focus, athletic performance and weight-loss results.

“Guarana might promote weight loss when used in combination with mate and damiana. However, more evidence is needed to rate guarana for this use,” states WebMD. [5]

Drugs.com notes that, “The appetite suppressant effect is related to the caffeine content. The energy that guarana tablets are reported to give also is due to caffeine.” [6]


Niacin (niacinamide)

A form of vitamin b3, which supports digestive system health, energy production, and overall wellness. Some research has linked niacin to lower risk for high cholesterol and diabetes.

Mayo Clinic says, “Niacin is a B vitamin that’s made and used by your body to turn food into energy. It helps keep your nervous system, digestive system and skin healthy.” [7]

The University of Maryland Medical Center reveals, “In type 1 diabetes, the body’s immune system mistakenly attacks the cells in the pancreas that make insulin, eventually destroying them. Niacinamide may help protect those cells for a time. More research is needed. Researchers have also looked at whether high-dose niacinamide might reduce the risk of type 1 diabetes in children at risk for the disease. One study found that it did.” [8]


Also called vitamin B1, this nutrient is found in foods such as nuts, fish, pork, seeds, whole wheat bread and green peas. It helps the body process carbohydrates and produce energy.

“Thiamin (vitamin B-1) helps the body generate energy from nutrients. Also known as thiamine, thiamin is necessary for the growth, development and function of cells. Most people get enough thiamin from the food they eat,” says the Mayo Clinic. [9]


Side Effects

ThermoPlus Side Effects

  • Upset stomach
  • Increased urination
  • Sleeplessness
  • Burping
  • Dizziness

Research referenced in trusted publications and government websites like the National Institutes of Health refer to these side effects based on the ingredients in Thermoplus, not Thermoplus in particular. [10] [6] [5]

AdvoCare ThermoPlus Alternative

Thermoplus vs Leptilean

AdvoCare Thermoplus vs. Leptilean

LeptiLean was another weight loss product available from Advocare. Like ThermoPlus, it helps control appetite and boosts metabolism to promote weight loss. However, it’s no longer available on the official website, which means it was likely discontinued. The ingredients in Leptilean are:

  • LeptiCore
  • PhosphoLean
  • Naringin extract
  • EGCG
  • Cat’s claw extract

This product is not intended for pregnant or nursing women. It is intended for use in ages 18 and older. Keep out of reach of children. In case of accidental overdose, seek professional help immediately.

ThermoPlus Pros and Cons

Our research lead us to a few pros and cons, based on what real users experienced. These include:


  • Can help speed along weight loss
  • Helps keep your energy levels high


  • Ingredient doses are too low, based on the amount used in studies

What Users Are Saying

“Love these products and they make you feel great, and they work if you stick to a healthy diet and exercise routine!”

“I think this pill serves its purpose for the most part. I did think I would have a little more of a reaction from it but I cant complain to much on the purpose of it. I will say if you do not like sage avoid this product and maybe opt for the liptilean instead. It has a sage extract in it and I burp it all day when I take this product, horrible taste!!”

“It may be a great supplement for metabolism but definitely affects sleep. It is a stimulant so beware if you want to sleep even if you take this early in the morning”

Bottom Line

The Bottom Line on ThermoPlus

Let us first say that ThermoPlus is a botanical supplement that contains natural sources of caffeine, which may help boost metabolism, focus and energy levels to some degree. After all, this stimulant is backed by some actual research. We also like that a 30-day satisfaction guarantee is posted on the website. But, we did find a few things we don’t like about this herbal diet supplement:

  • Quite a few users saw no results at all.
  • Some of the key ingredients lack solid weight loss research.
  • Customer feedback is not posted on the official website to support ThermoPlus.

If you want to slim down and see better weight-loss results, think about trying a botanical supplement not only backed by positive user comments, but also with an ingredient formula supported by solid science.

After sorting through hundreds of diet products, one that really stood out is Burn HD. It’s backed by a solid money-back guarantee and contains four key ingredients shown to help ignite metabolism, spark energy levels and improve fat loss results.

Also, you can try a 2-Week Sample of Burn HD hassle-free, and get started dropping those pounds.

ThermoPlus Ingredients

Thermoplus is an Advocare supplement that's formulated to boost metabolism while reducing hunger. The company does a great job of sharing the ingredient label and details, but a close look tells us there's nothing new or exciting in this one.

Other Ingredients: Gelatin, magnesium stearate, rice flour

We thoroughly examined ThermoPlus ingredients to give you the important details.

Sage Extract

First off, sage is a common herb that’s used in cooking and teas. The leaves are also used to make some alternative medicine. It has natural antiseptic properties, and contains some flavonoids.

What is it Supposed to Do?

Some studies have shown that sage extract[1] can help reduce high cholesterol levels, improve memory, and minimize menopausal symptoms. It’s also added to some diet supplements to help reduce stress levels and promote weight-loss. However, there is no evidence that it actually reduces body weight.

Clinical Research

According to Livestrong.com, “There are no scientific studies linking sage consumption to weight loss.” On the other hand, WebMD says, “Taking extracts of two different sage species (Salvia officinalis and Salvia lavandulaefolia[2]) for 4 months seems to improve learning, memory and information processing in people with mild to moderate Alzheimer’s disease.”

Oolong Tea Extract

This is one tea variety that is partially fermented. Unlike green tea, which is unfermented, and black tea, which is fully fermented. Oolong tea contains theobromine, caffeine and theophylline. It’s typically consumed as a hot beverage.

What is it Supposed to Do?

Oolong tea extract is sometimes used in weight-loss pills. It provides polyphenols and caffeine, which may help boost metabolism. This might help burn off more fat and calories.

Clinical Research

Some obesity studies have been done with oolong tea. According to the National Institutes of Health, a six-week trial was performed. It showed that, “Oolong tea could decrease body fat content and reduce body weight through improving lipid metabolism.”

Guarana Extract

Sometimes called Brazilian cocoa or paulinia cupana, guarana is a plant that grows in the northern parts of Brazil. It’s often used in energy drinks, weight-loss supplements, and even some medicine.

What is it Supposed to Do?

There are some claims that guarana helps promote weight-loss and mental performance. It contains some caffeine. This stimulant and diuretic can help boost alertness and elevate metabolism to some degree.

Clinical Research

There is information that links guarana to weight reduction. WebMD states, “There’s some evidence that guarana – when used along with other supplements – may promote weight-loss.” However, it goes on to say, “As a weight-loss supplement, caffeine may work best when combined with the polyphenol compounds in green tea.”

ThermoPlus Scientific Abstracts


Sage’s essential oils elevated hepatocyte sensitivity to insulin as well as suppressing gluconeogenesis. The effects, overall, mirror those of the drug metformin, a pharmaceutical inhibitor of gluconeogenesis utilized in type 2 diabetes mellitus treatment and prevention. None of these activities were noticed in cultures of rat hepatocytes when isolated from streptozotocin-induced diabetic rats. These results seem to suggest that sage tea fails to contain anti-diabetic effects at this level. Its effects on fasting glucose levels within normal animals, however, and its metformin effects on rat hepatocytes seem to indicate that sage could be helpful as a food supplement with the aim of preventing type 2 diabetes mellitus by decreasing plasma glucose of those at risk. [1]

Oolong Tea Extract

The Oolong tea was brewed every morning. The Oolong tea was ingested at room temperature (at 300 ml per serving). Participants ingested each treatment for 3 days – on the third day, indirect calorimetry in a room calorimeter measured energy expenditure. For the course of 3 days, participants ingested a normal American diet. The energy content of this diet was designed specifically for each individual’s needs as determined from an initial measure of 24 hour energy expenditure by calorimetry. Energy expenditure substantially rose, relative to the water treatment, to 2.9% and 3.4% for the tea and caffeinated water treatments. This elevation over water by itself represented an added expenditure of 281 kJ per day and 331 kJ per day for participants treated with the tea and caffeinated water. Additionally, fat oxidation was substantially higher (by 12%) when individuals ingested the full-strength tea as opposed to water. [2]

Guarana Seed Extract

Guaranà at 350 mg for three times per day just following breakfast or placebo were administered for 5 straight days. Observations and assessments were carried out one day after the final ingestion and included the PWB (psychological well-being) scales, SAS (self-rating anxiety state scale) and Bond-Lader mood scale. There were no substantial alterations between placebo and the guaranà in any of the criteria listed previously, as well any of the 16 different mood scales. In conclusion, healthy participants in a 5 day treatment with guaranà used according to the label’s instructions delivered no evidence for any significant effects on anxiety, psychological well-being and mood. Control studies are needed to further assess the benefits in comparison to the labeled claims. [3]


Previous ThermoPlus Review (Updated January 1, 1970):

What You Should Know about ThermoPlus

ThermoPlus by Advocare is a weight loss supplement designed for people looking to have a healthy metabolism and suppress their appetite. The key ingredients in ThermoPlus's formula are sage extract, oolong tea extract, guarana extract, thiamine and niacin. The product's webpage contains 4 customer testimonials claiming that the formula benefits very well as a weight loss program. All of these claims suggest using ThermoPlus along with other Advocare products like Spark energy drink and Catalyst. Here, we will try to decipher if ThermoPlus can promise any weight loss benefits when taken by its self.

ThermoPlus Ingredients

Sage extract, oolong tea extract, guarana extract, thiamine, niacin.

Product Features

The ThermoPlus website does not even attempt to scientifically explain how their product works. The link for Product Page leads to a downloadable brochure featuring an analysis of the product. Statements like "Sage works to support weight loss" are not backed up by any clinical studies, they are simply followed with an asterisk claiming they are not evaluated by the FDA. The ingredient list does not state which of the eight families of Sage their extract comes from. Oolong tea is included in this formula to serve a similar purpose to that of Green Tea. There is no evidence showing that oolong tea can be beneficial in a weight loss program or if it is responsible for any level of caffeine in this supplement. Guarana has been backed by some clinical studies as a metabolism booster, a fat cell reducer, and an antioxidant. This plant is generally regarded as safe in America. Thiamin, or Vitamin B1, helps convert blood sugar into energy and is a very important element in muscle building. Niacin is also needed for over fifty body processes like metabolizing proteins.

Advantages of ThermoPlus

  • Niacin and Thiamin are beneficial and essential vitamins.
  • Levels of ingredient dosages are safe.
  • Guarana has been suggested to improve mood and alertness.

Disadvantages of ThermoPlus

  • Claims lack clinical studies.
  • Customer testimonials seem to be advertisements for other Advocare products.
  • Niacin as a supplement can cause gastrointestinal discomfort.
  • Guarana can cause dizziness, headaches, and jitters.


The ingredients of ThermoPlus are primarily botanicals that promise an increase in energy and a boost in metabolism. The way it works is simple: the energy you get from the guarana and the tea gives you energy when you exercise. Other than that, this product does not perform thermogenesis (fat burning) when taken by its self. There is a reason why Advocare always recommends taking their products along with additional products: because one can't get the job done alone.

  •  Loved the product.
    Alyssa (Verified User)

    I love Thermoplus! All of Advocare’s products are tested through an outside company called Informed Choice. They text over 200 dirty or banned substances or metals. This product slightly changes your inner core and you can burn about 300 calories extra a day! I highly suggest it!

  •  Hated the product.
    Anonymous (Verified User)

    Do not take Thermoplus if you are an anxious person! I took it on my 11th day as an add on and it made me feel like I was on crack. I got very anxious, fast heart beat, shaky. I do not recommend this supplement unless you are really overweight or like feeling like you are on drugs

    • Montana (Editor)

      Hello! Many weight loss supplements contain too much caffeine. Our top rated product, Dietspotlight Burn, contains less caffeine than a small cup of coffee in each serving. You may want to check it out!
