No studies have assessed the effectiveness of the Thrive Patch for weight loss.
However, three of the ingredients in the Thrive Patch have been studied in this regard.
ForsLean
The effects of the herb Coleus forskohlii on weight has been studied in two small randomized, double-blind, controlled studies — one in men and one in women.
In women, it had no effect on weight, but the herb was noted to have a small effect on body composition in men and resulted in a 4% reduction in body fat (2, 3).
However, the results in the men’s study were variable and the effect on body weight insignificant.
Green Coffee Bean Extract
Green coffee beans are unroasted. They’re a source of chlorogenic acid, a carbohydrate blocker that aids weight loss by blocking the absorption of carbs.
One 12-week study found that participants drinking coffee enriched with chlorogenic acid lost an average of 11.9 pounds (5.4 kg), compared to 3.8 pounds (1.7 kg) for the control group that received regular coffee (4).
However, another study on coffee bean extract found that it had no significant effect on weight (5).
Garcinia Cambogia
Garcinia cambogia is a popular weight loss supplement. It’s said to aid weight loss by increasing fat burning and reducing appetite.
Results of weight loss studies have been mixed, with the positive studies only showing marginal effects (6).
For example, in one 12-week study, participants taking the supplement only lost 1.94 pounds (0.88 kg) more than the control group (7).
Effectiveness of the Patch’s Technology
Overall, research to support that any of the active ingredients in the Thrive Patch are effective for weight loss is currently insufficient.
Additionally, it’s unclear how much of the active ingredients are in the patch and whether they’re present in sufficient amounts to have any effect.
Dermal fusion technology (DFT) — the technology used to deliver the ingredients — has also not been studied, and it’s impossible to know how effective it is at delivering the active ingredients from the patch through your skin.
This means that in addition to a lack of evidence for the effectiveness of the ingredients within the patch, it’s currently unclear whether the patches are even able to increase your blood levels of these active ingredients.
Summary Research to back up claims that the Thrive Patch or its individual ingredients aid weight loss is currently lacking. The technology used to deliver active ingredients through the skin has also not been studied.
