Vitamin D Deficiency and Fibroids

In late 2008, the Star Tribune printed the following article about vitamin D:  Here are the highlights:

  • Vitamin D deficiency is now an epidemic
  • Researchers have linked deficiencies to 17 kinds of cancer, autoimmune diseases, chronic pain, heart disease, depression and ADHD
  • Vitamin D regulates hundreds of genes, especially those associated with cell growth
  • It’s cheap and readily available via the sun
  • Those who live in colder climates do not get enough of the vitamin as they tend to spend more time inside than out

Further research lead me to the following clinical trial: Vitamin D inhibits myometrial and leiomyoma cell proliferation in vitro (

Here are the highlights:

  • The study was done in vitro (in a test tube)
  • In both myometrial and leiomyoma cells, 0.1 nM physiologic level of 1,25(OH)2D3 inhibited growth by 12% when compared with controls
  • Conclusion: Both myometrial and leiomyoma cell growth in vitro was effectively inhibited by 1,25(OH)2D3. Vitamin D may play a role in the growth of uterine leiomyomas.
  • (Note: leiomyoma = fibroids)

Another study concluded that vitamin D inhibits proliferation of human uterine leiomyoma cells via catechol-O-methyltransferase (

At this point, I decided to incorporate vitamin D into my diet.  Here’s my regimen:

  • Soak up the sun: Daily walks that last at least 30 minutes
  • Cod liver oil (very good source)
  • Vitamin D3 tablets (winter)
