Vitamin cocktail may shrink fibroids, reduce surgery need
NCT ID NCT05409872
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a 3-month treatment with a combination of vitamin D, green tea extract (EGCG), vitamin B6, and D-Chiro-inositol in 108 women with uterine fibroids who were planning surgery. The goal was to see if the supplement could ease symptoms and possibly help some women avoid surgery. The approach was a double-blind, randomized trial, meaning neither the participants nor the doctors knew who got the real supplement or a placebo.
