Can vitamin D be used to reduce the fibroids of the boy? Current clinical research

 8:53am, 27 August 2025

Reader Ms. Liu used the "Contact Me" on this website on May 21, 2020 to ask me two questions. One of them is: My uterine fibroids are about 9cm, and the concentration of vitamin D in my body is very low after blood tests. Can vitamin D be supplemented with vitamin D be relieved and enlarged or further reduced myomas? Should I replenish it every day?

Medite fibroids are the most common benign pelvic tumors in the myocardium, and most patients will not have obvious symptoms or feelings. If there are serious symptoms, the treatment method is usually mainly surgery or medicine. If the symptoms are mild, adjustments to life habits, such as reducing the intake of red meat and increasing movement, are also one of the options.

Some studies have found that women with uterine fibroids usually have low concentrations of vitamin D in their bodies, and animal experiments have also shown that supplementing vitamin D seems to reduce uterine fibroids. A doctor who vigorously advocated that everyone should take vitamin D supplements in Taiwan published a new book and article in February this year, proclaiming that a 2017 clinical trial found that vitamin D supplements clearly controlled the maternal fibroids of the woman. However, in fact, such clinical trials were not published until 2019. If you don't believe it, please read this expert opinion published on 2020-1-17 Vitamin D and uterine fibroids: preclinical evidence is in; time for an overdue clinical study! (Vitamin D and uterine fibroids: preclinical evidence; it is time to conduct a clinical study that has been waiting for for a long time!)

There are currently two articles on whether supplementing vitamin D can reduce uterine fibroids (both from Iran):

2019: The effect of vitamin D supplementation on the size of uterine leiomyoma in women with vitamin D deficiency.

2020: Effect of oral consumption of vitamin D on uterine fibroids: A randomized clinical trial.

The article in 2019 concluded that vitamin D can reduce fibroids, but please note that this article was published in a journal called the Caspian Journal of Internal Medicine, which was published in Iran, and its impact factor was only a very low 1.3. So, a clinical research report for a prostitute, published in a low-level internal science journal, has clearly stated that it is a problematic study (at least not subject to attention).

The 2020 article says that vitamin D supplementation cannot reduce fibroids, but it still suggests that further research should be done. This article was published in a journal called Complementary Therapies in Clinical Practice, and the impact factor of this journal is only a very low of 1.6. Therefore, the conclusion of this research still needs to be watched coldly.

In summary, although women with uterine fibroids usually have a lower serum vitamin D concentration, and animal experiments have also shown that vitamin D supplementation seems to reduce uterine fibroids, current clinical studies still cannot prove that vitamin D supplementation can reduce uterine fibroids. In fact, this Clinical Certification Deficiency is a common phenomenon in the field of vitamin D research. In other words, preclinical research always beats the drum, but postclinical research always keeps it silent. If readers want to know the reason for the Central Plains, please search this website (about 50 articles) or refer to the truth about my new book, Vitamin D.
