Is Omega-3 Good for the Prostate?


The prostate is a gland in men that produces fluid for semen. Enlargement and dysfunction of the prostate gland often occurs with aging. Prostate disorders negatively impact urinary function and quality of life.

Omega-3 fatty acids provide anti-inflammatory effects that may benefit prostate health. But what does the research say about the effects of omega-3s on prostate enlargement and prostate cancer risk?

Below is an evidence-based look at the potential benefits and risks of omega-3 supplementation for prostate wellness.

Is omega-3 good for prostate?

An Overview of Prostate Health

The prostate is a walnut-sized gland located under the bladder that wraps around the urethra. It secretes nutrient-rich fluid that mixes with sperm to form semen.

Diseases that affect the prostate include:

  • Benign prostatic hyperplasia (BPH) – noncancerous enlargement causing urinary symptoms
  • Prostatitis – inflammation causing pain and urinary problems
  • Prostate cancer – most common cancer in men besides skin cancer
  • Chronic pelvic pain syndrome – persistent pain in the pelvis, genitals and perineum

Prostate disorders severely reduce quality of life by causing uncomfortable urinary and sexual symptoms. Finding natural ways to protect prostate health is key.

Could increasing omega-3 intake help maintain a healthy prostate? Let’s analyze the evidence.

How Might Omega-3s Support Prostate Wellness?

Omega-3s provide several beneficial effects that may help prevent and manage common prostate problems:

  • Powerful anti-inflammatory effects – Reduces inflammatory chemicals that contribute to prostate enlargement and damage.
  • Increased blood flow – Improves circulation to the pelvic region to supply prostate tissue with oxygen and nutrients.
  • Healthy cell membranes – DHA maintains fluidity and integrity of prostate cell membranes.
  • Lower testosterone breakdown – May inhibit conversions of testosterone to DHT, which contributes to BPH.
  • Reduced oxidative stress – Limits free radical damage to prostate tissue DNA and cells.
  • Antiangiogenic effects – Slows growth of new blood vessels to prevent rapid tumor expansion.

Through these wide-ranging mechanisms, ensuring adequate omega-3 intake may help optimize prostate health and function as men age.

What Does Research Say About Omega-3s and The Prostate?

Numerous studies have looked at associations between omega-3 intake from diet or supplements and risk for common prostate disorders:

Benign Prostatic Hyperplasia

  • Higher omega-3 intake is linked to significant reductions in BPH risk, especially lethal types, in several observational studies.
  • Randomized trials show small decreases in BPH symptoms like frequent/urgent urination with omega-3 supplementation.
  • Omega-3s appear protective but larger clinical trials are still needed.


  • Increased omega-3 consumption reduced pain severity by 22-40% in two small studies of chronic prostatitis patients.
  • More research is needed as current evidence is limited.

Prostate Cancer

  • Higher omega-3 tissue levels are linked to lower prostate cancer risk in some epidemiological data.
  • However large meta-analyses show no reduction in prostate cancer incidence with omega-3 intake.
  • Omega-3s do not appear to lower prostate cancer risk but may slow progression in those with established diagnoses.

Overall, increasing omega-3 intake shows most promise for preventing BPH development and reducing symptoms from enlarged prostate. Benefits for prostatitis pain and prostate cancer prevention still need further study.

Concerns About Omega-3s Promoting Prostate Cancer?

Back in 2013, one observational study reported higher blood omega-3 levels were associated with increased prostate cancer risk. This led to widespread concerns about omega-3 safety.

However, a multitude of subsequent analyses have disproven this link. Omega-3s do NOT appear to raise prostate cancer risk. Limitations of the initial concerning study include:

  • Did not differentiate ALA vs. EPA/DHA omega-3 source
  • Did not consider omega-3 dosage or duration
  • Single blood draw subject to transiency
  • Correlation does not equal causation
  • Possible detection bias in fish oil users getting more frequent PSA tests

Over a dozen higher quality analyses since have found omega-3 intake is safely neutral for prostate cancer development in most men. Omega-3s remain one of the most beneficial supplements for overall wellness.

Are Omega-3s Safe for the Prostate? Any Side Effects?

Multiple large reviews conclude omega-3 supplements are safe for prostate health at typical doses. Possible side effects may include:

  • Fishy aftertaste
  • Gastrointestinal discomfort
  • Loose stools
  • Increased bruising/bleeding at very high doses – unlikely at amounts under 3 grams per day

To minimize side effects:

  • Choose quality oils verified for purity
  • Take with meals
  • Start with lower doses and increase slowly
  • Split dose throughout the day

Those already on anticoagulant medications or with clotting disorders should exercise caution and consult their doctor before supplementing at high levels.

Otherwise, omega-3s have an excellent safety profile, even with long-term daily use. Taking up to 1,000 mg daily under medical guidance is unlikely to pose harm for the prostate.

Lifestyle Approaches Also Important for Prostate Health

In addition to omega-3s, comprehensive lifestyle and dietary strategies should be part of any prostate wellness plan, including:

Exercise regularly – Activity enhances circulation to the pelvis and helps maintain a healthy weight.

Reduce inflammatory foods – Limit red meat, dairy and omega-6 oils; increase plant foods.

Increase lycopene – Lycopene-rich tomatoes may help prevent prostate enlargement and cancer.

Manage stress – Chronic anxiety and stress negatively impact prostate health.

Stay hydrated – Drink adequate fluids, especially water. Avoid caffeine and alcohol.

Practice pelvic floor exercises – Kegels improve blood flow and muscular support to the prostate.

Get enough vitamin D and zinc – Supplement if deficient, with medical guidance.

A diet high in whole foods, healthy fats, vegetables, and antioxidants provides the ideal nourishing foundation for lifelong prostate vitality. Omega-3s may offer additional anti-inflammatory benefits.

Should I Take Omega-3s for Prostate Health?

In summary, research suggests higher omega-3 intake may help prevent benign prostate enlargement, reduce PSA levels, and decrease urinary symptoms associated with BPH and prostatitis.

However, evidence is still inconclusive on omega-3s for lowering prostate cancer risk in healthy individuals. They do not appear harmful or protective against prostate malignancies based on current data.

Yet given their stellar safety profile and multitude of other health benefits, taking an omega-3 supplement is reasonable for optimizing prostate health and function in aging men, under medical supervision.

For well-rounded support, seek out an omega-3 product delivering a combination of both EPA and DHA fatty acids. Aim for 500-1,000 mg daily with food for optimal effects.

Pair omega-3 supplementation with a diet and lifestyle conducive for lifelong prostate wellness.
