The men, who were being managed with active surveillance, were randomized to receive the supplement 3 times a day for 6 months or placebo. At 6-month follow-up, the median increase in PSA was 63.8% lower in the supplement groups than in the placebo group (14.7% vs 78.5; P =. 0008).
What supplements can affect a PSA test?
Vitamins C, E, and D, lycopene, selenium, curcumin, flavonoids, catechins, fruit and fruit extracts have all been studied and postulated to affect PSA concentrations; however, in the vast majority, evidence from existing RCTs appears inconsistent [40] and does not seem to support the use of antioxidants.

What is the best supplement to lower PSA?
One study in 66 men with BPH found saw palmetto supplements to be more effective at lowering levels of prostate-specific antigen (PSA) — a protein that can signal an issue with prostate health — and improving urinary symptoms when combined with beta-sitosterol ( 14 ).
Does Zinc raise PSA levels?
A cutoff value of 100 microg/mL for serum zinc concentration provided a sensitivity of 90.5% and a specificity of 32.7% in elevated PSA range , and a sensitivity of 93.3% and specificity of 27.1% in gray zone, respectively.
Does saw palmetto affect PSA results?
Saw palmetto is an effective treatment for the symptoms of BPH. It appears to be as effective as finasteride and is better tolerated, less expensive, and less likely to decrease PSA levels .
What is an alarming PSA level?
PSA levels under 4 ng/ml are generally considered normal, while levels over 4 ng/ml are considered abnormal. PSA levels between 4 and 10 ng/ml indicate a risk of prostate cancer higher than normal. When the PSA level is above 10 ng/ml, risk of prostate cancer is much higher.
What can cause a false high PSA reading?
- Increasing age.
- Benign prostate hyperplasia (BPH), a condition that commonly develops as those assigned male at birth age and causes the prostate to grow in size.
- Inflammation or infection of the prostate, like prostatitis or a urinary tract infection.

How does biotin affect PSA test?
Circulating biotin levels greater than 20 ng/mL are reported to exhibit interference in high sensitivity troponin T (hs-TnT), thyroid stimulating hormone (TSH), and in prostate specific antigen (PSA) among other assays when using our Cobas® 6000 immunoassay analyzer (Roche Diagnostics, IN, USA).
Does fish oil affect PSA levels?
The interventional studies using fish oil supplements in patients with PrCa showed no impact on prostate-specific antigen levels ; however, 2 studies showed a decrease in inflammatory or other cancer markers.
Can vitamin D lower PSA?
A double-blinded clinical study found that vitamin D supplementation reduced prostate specific antigen (PSA) level and enhanced survival rate in patients with prostate cancer [14].

At what PSA level should a biopsy be done?
A lower percent-free PSA means that your chance of having prostate cancer is higher and you should probably have a biopsy. Many doctors recommend a prostate biopsy for men whose percent-free PSA is 10% or less, and advise that men consider a biopsy if it is between 10% and 25% .
