This independent 16-week clinical investigation evaluated the effects of Thyrafemme Balance supplementation in 35 female adults with self-reported thyroid concerns. The study found significant improvements in fatigue, quality of life, and metabolic parameters, including resting energy expenditure, without alteration of standard thyroid function tests. Results support the potential role of this supplement as a complementary approach for supporting general well-being in this population, with further randomized controlled trials recommended to confirm these findings.
