NCT ID NCT05448365
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study tests whether a daily supplement containing vitamin D, EGCG (from green tea), D-chiro-inositol, and vitamin B6 can shrink uterine fibroids in women who are eligible for surgery. Sixty women will take either the supplement or a placebo for three months. The main goal is to see if the fibroids get smaller and if fewer women end up needing surgery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- combination of vitamin D, epigallocatechin gallate (EGCG), D-chiro-inositol, and vitamin B6
- What this could lead to
- If it works, this could offer a natural supplement option to shrink fibroids and help some women avoid surgery.
- What could go wrong
- This is a small early-phase trial with only 60 participants and no phase designation, so results may not be conclusive. The supplement may not shrink fibroids enough to make a real difference.
