Fibroids without surgery

What green tea extract and vitamin D actually did in trials

BModerate evidence

Uterine fibroids are common and often managed surgically, but there is real randomized evidence for a nutritional approach in smaller fibroids.

In a randomized controlled trial, green tea extract (EGCG) reduced total fibroid volume by 32.6% while the placebo group's grew by 24.3%. Symptom severity fell 32.4% and quality of life improved 18.5%. Combined vitamin D and EGCG shows synergistic results in preliminary work.

Important safety note. This is not the same as drinking green tea. Concentrated EGCG extracts carry a documented risk of liver injury, which is why hepatic safety has been studied specifically in reproductive-aged women. If you try this, it should be with your provider's knowledge and with liver enzymes monitored — not as an unsupervised supplement purchase.
