Garcinia Cambogia

Garcinia Cambogia supplements produce only negligible weight loss, with a 2020 meta-analysis of 12 randomized trials concluding an average of just 0.88 kg more than placebo over 8 weeks. This outcome is 90% less effective than the 1.5 kg per month typical of calorie-restricted diets alone, while raising concerns about liver toxicity in multiple case reports. Priced at $20-$40 per month, these supplements fail to meet the minimal threshold for clinical significance defined by FDA guidelines, offering less than 1% of the effect needed for weight loss drugs like orlistat. Garcinia Cambogia even trails #7 on this list in terms of safety data, as its hepatotoxic risk has been flagged in pharmacovigilance alerts since 2018.
