The women used 800 mg of green tea extract (EGCG) or a placebo, taken after meals, daily for 4 months. In the placebo group (n = 11), fibroid volume increased (24.3%) over the study period; however, patients randomized to green tea extract (n = 22, 800 mg/day) treatment showed significant reduction in total UF volume. In addition, EGCG treatment significantly reduced fibroid-specific symptom severity compared to the placebo group. Anemia also significantly improved in the EGCG treatment group (anemia can occur with fibroids). No adverse effects were observed in either group.
For those choosing to use an EGCG supplement, a critical consideration is to use a documented pharmaceutical grade green tea extract standardized to a high EgCG content, low in caffeine and NOT derived via a chloroform extraction process. Furthermore it is essential that any green tea supplement be tested for the existence of contaminating heavy metals. Relentless Improvement brand Green Tea EgCG Supplement meets all of these qualifications and carries a public Certificate of Analysis of purity, sterility and claimed EGCG content.
