Thermo Burn Review: Ingredients, Side Effects & Cost

In our ongoing search for useful weight-loss products, we came across Thermo Burn, a supplement claiming to “burn fat quicker without dieting or exercise.” Based on what we found, there isn’t much clinical evidence to back up that marketing claim.

Our research team spent time digging through the ingredients, potential side effects, the science behind the formula, and whatever user feedback we could track down, then compressed it all into this review so you have the full picture on this fat burner.

What Is Thermo Burn?

Thermo Burn is a dietary supplement the manufacturer claims can help with weight loss, craving control, metabolism, and muscle building, all without requiring any changes to diet or exercise. The marketing suggests it can rapidly melt body fat, block fat production and storage, and promote leaner muscle, while also curbing appetite, boosting energy, and improving mood.

Sold in capsule form, the product is often promoted as a “miraculous weight loss formula” built around five key ingredients: forskolin, L-carnitine, garcinia cambogia, ginseng, and vitamin B12, which the manufacturer says work together to burn fat and block its production and storage in the body.

Despite the marketing, we couldn’t find Thermo Burn available for purchase through any online or offline retailer during our most recent search, suggesting the product may no longer be on the market.

Here’s what some of the underlying ingredient research actually shows: hydroxycitric acid, the active compound in garcinia cambogia, was found to help control appetite in animal studies published in Molecular and Cellular Biochemistry. Forskolin consumption was linked to improved body composition after 12 weeks, according to Obesity Research. And Clinical Nutrition ESPEN reports that L-carnitine supplementation provides “a modest reducing effect on body weight, BMI and fat mass,” particularly in adults who are overweight or obese.

How Did Thermo Burn Start?

It’s unclear exactly when Thermo Burn first entered the weight-loss market, though it’s said to be manufactured in a “state-of-the-art FDA registered laboratory.”

Thermo Burn Claims

Thermo Burn is marketed as a non-prescription diet pill that burns fat without diet or exercise changes, described on the label as “keto system approved” and said to stop new fat production. The website also claims Dr. Oz endorsed the product’s ability to aid weight loss in multiple ways — melting fat, revealing lean muscle underneath, and strengthening bones and muscles.

Thermo Burn Ingredients

Garcinia Cambogia

A pumpkin-shaped fruit native to India and Southeast Asia, also known as Brindle Berry or Malabar Tamarind. Its key active component, hydroxycitric acid (HCA), has been linked in some research to weight loss, and is often said to boost serotonin, block fat production, elevate mood, and suppress appetite, according to the National Institutes of Health.

Forskolin

An herbal extract that helps create the enzymes adenosine and lipase.

L-Carnitine

An amino acid derivative of lysine found in foods like beef, pork, fish, chicken, and dairy, playing a role in the body’s energy production.

Ginseng

A plant used in traditional medicine to address poor cognitive function, high stress levels, and inflammation, and sometimes taken to help elevate mood. It comes in 11 different varieties and is commonly sold as a standalone supplement.

Vitamin B12

A water-soluble vitamin found in eggs, shellfish, poultry, milk, and fish, essential for red blood cell formation, nerve function, and cell metabolism, and often included in supplements aimed at boosting energy and athletic performance.

Does Thermo Burn Work?

Does Thermo Burn actually deliver on its promises? This is where things get murkier. Garcinia cambogia has shown mixed results for weight loss and fat reduction, and Medical News Today notes that “longer tests need to be carried out on bigger groups of people to understand the safety and effectiveness of garcinia or HCA fully.” A study in Obesity Research found that 250mg of a 10% forskolin extract taken twice daily over 12 weeks favorably altered body composition in overweight and obese men, while also increasing bone mass and free testosterone. Separately, ginseng may help with energy and cognitive function while combating inflammation, per Medical News Today.

Thermo Burn and Weight Loss: A Closer Look

The Journal of the International Society of Sports Nutrition found that coleus forskohlii “does not appear to promote weight loss but may help mitigate weight gain in overweight females,” with no clinically significant side effects. The Journal of Obesity notes that garcinia extracts and HCA “can cause short-term weight loss.” On the other hand, research in the Annals of Nutrition and Metabolism found L-carnitine supplementation did not positively affect body composition or weight loss in rats, and Current Drug Metabolism found that while L-carnitine appears safe for conditions like fatigue or exercise performance, it doesn’t seem to have a significant effect.

How to Take Thermo Burn

Potential Thermo Burn Side Effects

Possible side effects from Thermo Burn’s ingredients include nausea and headaches.

Thermo Burn Cost and Guarantee

The official Thermo Burn website lists the price at $69.95 per bottle for a 30-day supply, though a free trial allows you to try the product for 30 days at no charge before being billed $29.95 for access to the “Thermo Burn Club.” From there, you’re automatically enrolled in an auto-shipment program billed $69.95 every 30 days. A 60-day money-back guarantee applies, but the bottle must be unopened, a $5.95 restocking fee applies, and you’re responsible for return shipping.

Thermo Burn Pros and Cons

Pros: A trial offer and a 60-day return policy.

Cons: Potential side effects, limited customer reviews, and a fairly high price for what you get.

Was Thermo Burn Ever on Shark Tank?

There’s some online chatter linking Thermo Burn to Shark Tank, but nothing suggests the product was ever actually pitched or featured on the show. This kind of false association with popular TV programs is a common marketing tactic in the diet-pill space.

The Bottom Line on Thermo Burn

Should you invest in Thermo Burn? We’re not convinced. There’s no solid research or clinical study behind the actual product, the ingredient dosages aren’t disclosed, and it doesn’t make much sense to claim results without diet or exercise when both are well established as key drivers of real, lasting weight loss. If you’re struggling to reach a weight-loss goal or break through a plateau, you’re generally better served looking for an approach backed by legitimate clinical research and built around sustainable diet and lifestyle changes rather than a single miracle pill.
