How to lower PSA scores

Updated July 19, 2017

PSA (prostate specific antigen) is a component of semen found in normal adult males. Elevated levels of PSA are correlated with an increased risk of prostate cancer and benign prostate hyperplasia. There is some evidence that the higher a male's PSA levels, the less responsive he will be to cancer treatment. However, there are some useful strategies that have been shown to lower PSA levels.

Incorporate pumpkin seed oil into your daily diet. Pumpkin seed oil is most effective when combined with a diet low in saturated fat, but rich in vitamin D. Supplementation of vitamin D at 10 IU daily may also prove beneficial.

Take a saw palmetto supplement daily. Extracts of saw palmetto are more effective than the raw herb alone.

Obtain purified, pharmaceutical-grade Swedish pollen extract. Dietary Swedish pollen extract is not in fact pollen, but a blend of biologically active fat- and water-soluble plant fractions. It is one of the most well-researched supplements used to lower PSA levels.

Supplement with an extract of Pygeum africanum. Pygeum is a well-respected herb used in relieving the symptoms of benign prostate hyperplasia, as well as lowering PSA levels.

Reduce your weight. Obesity is strongly correlated with elevated PSA levels, particularly in African-American populations.

Increase your consumption of antioxidant-rich foods. Colourful vegetables, berries and pomegranates are all foods that are extremely abundant in antioxidants. Diets high in antioxidants are correlated with low PSA levels in males between the ages of 51 and 71.


Consult your doctor before starting any dietary regime or daily supplement. Saw palmetto can cause gastrointestinal distress. Reduce this by taking it with food.
