Vitamin D for Prostatitis

What Is Vitamin D?

Vitamin D is an essential vitamin that has many critical roles in men’s health, including prostate health and immunity. This vitamin has demonstrated effect on managing symptoms of prostatitis (both bacterial and nonbacterial chronic prostatitis/chronic pelvic pain syndrome [CP/CPPS]) and enlarged prostate, also called benign prostatic hyperplasia (BPH). That is why some experts recommend taking vitamin D for prostatitis. Vitamin D also has anticancer properties.

Vitamin D for Prostatitis—Does It Work?

Vitamin D for prostatitis has significant clinical studies and research behind it, making it a Tier 2 supplement for prostatitis.

Studies on vitamin D for prostatitis include the following:

  • A review published in the International Journal of Andrology noted that scientists are beginning to appreciate chronic inflammation as a potentially important factor in men who have BPH, as well as the role of bacterial prostatitis and nonbacterial CP/CPPS. The authors also pointed out that “the mechanism of action of VDR [vitamin D receptor] agonists supports an important role of chronic inflammation in BPH pathogenesis and strengthens the concept of these agents as a therapeutic option for pharmacological treatment of BPH.”  (Fibbi 2010)
  • The Journal of Autoimmunity published a study on prostatitis and vitamin D, in which investigators explored the effect of vitamin D receptor silencing on the development of experimental autoimmune prostatitis in mice. The researchers concluded, “Vitamin D receptor modulation holds the promise of interfering with autoimmune prostatitis.”  (Motrich 2009)

There is also research on vitamin D and BPH. While BPH is not directly related to prostatitis, looking at how vitamin D affects other prostate conditions can help us see the role of this vitamin in overall prostate health. Low levels of vitamin D are associated with prostatitis, BPH, and prostate cancer.

Studies on vitamin D for BPH include the following:

  • The relationship between vitamin D and BPH has been evaluated in a number of trials. One study evaluated 4,770 participants in the Prostate Cancer Prevention Trial who were free of BPH at baseline. Over seven years, 876 incident BPH cases were documented. When the investigators analyzed factors such as diet, alcohol, and supplement use via a food frequency questionnaire, they determined there were no associations between supplemental antioxidants and BPH risk, and there was “weak evidence for associations of lycopene, zinc, and supplemental vitamin D with reduced risk.” (Kristal 2008)
  • At least one study has reported that a low level of vitamin D circulating in the blood is linked to a greater risk of having an enlarged prostate or prostate cancer. An epidemiological study of 977 randomly chosen men investigated the prevalence of prostate disease based on blood samples, a questionnaire, and physical examination. Investigators found a 23.1% prevalence of BPH, 5.1% of prostatitis, and 3.7% of prostate cancer. Among other discoveries, the authors reported finding lower levels of vitamin D in men who had BPH and prostate cancer. Because vitamin D inhibits cellular proliferation, the authors noted, “Lower levels are confirmatory with its loss of protective role against prostate cancer.” (Galic 2008)
  • Additional evidence can be found in a study conducted in Italy in which researchers identified how the vitamin D receptor agonist elocalcitol, a synthetic derivative of vitamin D3, is capable of stopping growth of the prostate in men who have BPH. The process by which elocalcitol both stops inflammation and the growth of BPH cells is complex, and involves elocalcitol’s ability to significantly inhibit production of IL-8, a substance involved in BPH pathogenesis, by BPH cells stimulated with inflammatory cytokines, and IL-8-induced proliferation of BPH cells. The authors concluded that their data “provide a mechanistic explanation for the anti-proliferative and anti-inflammatory properties of elocalcitol in BPH cells.  (Penna 2009)

Uses and Side Effects of Vitamin D

The Vitamin D Council recommends taking 5,000 IU daily for two to three months, then asking your healthcare provider for a 25-hydroxyvitamin D test to check your levels. Once you know your body’s level of vitamin D, you can adjust the dosage until you blood levels are between 50 and 80 ng/ml. That is the healthy range recommended by the Vitamin D Council and other experts. It is important to take the right form of vitamin D, which is D3.

While vitamin D is added to milk, food is not the best way to get vitamin D. Getting 15 to 20 minutes of sunlight each day is the best source of vitamin D, but that is not always possible, so supplements are important as well. People over 50 are at increased risk for vitamin D deficiency.
