PSA Tests, Prostate Checkups and Supplements: What to Know Before You Test
PSA is a blood test for prostate-specific antigen. BPH and prostatitis can raise it, finasteride and dutasteride lower it, and a level above 4.0 ng/mL is generally considered abnormal. The USPSTF makes screening an individual decision for men 55 to 69 and advises against it from 70. Tell your doctor about every supplement.

The test01
What a PSA test measures
PSA stands for prostate-specific antigen, a protein made by the prostate that can be measured in a blood sample.
A raised PSA is not a diagnosis. The National Cancer Institute says BPH and prostatitis can raise PSA, and that a level above 4.0 ng/mL is generally considered abnormal, though some doctors use age-based cutoffs. It also says PSA testing is not recommended for routine screening of the general population, and that men considering it should talk through the benefits and harms with a clinician (NCI, PSA test).
In practice that means a PSA number is one piece of information, read with your age, symptoms, family history, examination and any earlier results. The trend over time often says more than a single number.
Screening advice02
What the USPSTF advises, by age
| Age | Grade | Plain meaning |
|---|---|---|
| 55 to 69 | C | An individual decision after discussing benefits and harms with a clinician |
| 70 and older | D | Recommends against routine PSA screening |
| Under 55 | Not graded here | Talk to a doctor if you have a family history or other risk |
The Task Force lists harms of screening that include false positives, biopsy complications, overdiagnosis and overtreatment (USPSTF, Prostate cancer screening). That is why the advice is a conversation, not a rule. Some men want the information and some prefer not to chase it, and both are reasonable.
Note the date: the statement is from 2018 and an update is in progress, so ask your doctor what the current advice is for you. Nothing on this site replaces that conversation.
Weighing it up03
The harms the Task Force lists, in plain words
Screening is not free of cost. The USPSTF names four kinds of harm, and knowing them helps you decide how you feel about testing (USPSTF, Prostate cancer screening).
| Harm | What it means for a man |
|---|---|
| False positive | The PSA is raised but no cancer is found, which can mean worry and more tests |
| Biopsy complications | A biopsy done to check a raised result can cause pain, bleeding or infection |
| Overdiagnosis | A cancer is found that would never have caused harm in the man's lifetime |
| Overtreatment | Treatment is given for a slow cancer, with side effects and no gain |
Those harms are balanced against the chance of finding a dangerous cancer early. The balance differs by age and risk, which is why the Task Force's grades differ by age band and why your doctor's view matters more than a headline.
What moves the number04
Medicines, supplements and PSA
Several things move PSA, and a supplement user should know which.
- Finasteride and dutasteride lower PSA. Men taking them are assessed with a lower cutoff, so tell the lab and your doctor before any test (MedlinePlus, Finasteride) (NCI, PSA test).
- BPH and prostatitis can raise PSA without any cancer (NCI, PSA test).
- Saw palmetto did not affect PSA more than placebo, even at high doses, in the sources we checked (MSK, Saw Palmetto) (NCCIH, Saw Palmetto).
- Pomegranate juice has been studied for PSA rise in men with already raised PSA, with conflicting results (MSK, Pomegranate).
- For the other ingredients we found no PSA studies; the effect is unknown.
Because no trial of Prostadine exists, nobody can say whether it changes PSA. The cautious step is the simple one: tell your doctor you take it, in the same way you would mention any medicine, and let them interpret the number.
A product that “supports prostate health” has not been shown to find, prevent or treat cancer. Check-ups and PSA decisions are about detecting problems, which no supplement does.

Before a PSA test
Ask whether the test is right for you
Discuss your age, family history and wishes. The USPSTF treats this as an individual decision for men 55 to 69 (USPSTF, Prostate cancer screening).
List every medicine and supplement
Include finasteride or dutasteride, saw palmetto and anything with seaweed or iodine. The lab needs the medicine list (MedlinePlus, Finasteride).
Mention recent events
Tell the clinician about any recent urinary infection or procedure, which can raise PSA temporarily.
Ask what happens with each result
Know in advance what a high, borderline or normal result would lead to.
Ask about repeating
A single raised result is often repeated before decisions are made.
The result06
A raised PSA is a question, not an answer
If a result is raised, the next steps depend on you and your doctor. They can include a repeat test, a closer look at medicines, a urine test to rule out infection, an examination, imaging or a referral to a urologist. None of those steps is a supplement.
It is worth saying plainly that a raised PSA has benign explanations such as BPH and prostatitis (NCI, PSA test), and that a normal PSA does not guarantee that nothing is wrong. That uncertainty is why the advice is a conversation. For more on the gland itself, see prostate basics; for questions to take with you, see the doctor visit guide.
- Saw Palmetto. Memorial Sloan Kettering Cancer Center, Integrative Medicine, 2023.Reports conflicting data on BPH symptoms (some trials improved, others showed no effect). Did not affect serum PSA more than placebo, even at high doses. Common side effects are stomach upset, diarrhea, fatigue, headache, decreased libido and rhinitis. Case reports include bleeding problems (including with rivaroxaban and during surgery), liver damage and pancreatitis. May increase bruising and bleeding risk with anticoagulants, antiplatelets and NSAIDs.
- Finasteride. MedlinePlus (National Library of Medicine), 2025.Prescribed for BPH; may control it but will not remove the cause, and symptoms may take at least 6 months to improve. Common side effects include erection problems, decreased sexual desire and ejaculation problems. Before any lab test, tell your doctor and the lab that you take finasteride.
- Prostate Cancer: Screening (Final Recommendation Statement). U.S. Preventive Services Task Force, 2018.Men 55 to 69: Grade C, screening with PSA is an individual decision after discussing benefits and harms with a clinician. Men 70 and older: Grade D, recommends against. Harms include false positives, biopsy complications, overdiagnosis and overtreatment. An update is in progress.
- Prostate-Specific Antigen (PSA) Test. National Cancer Institute, 2025.BPH and prostatitis can raise PSA. Finasteride and dutasteride lower PSA, so men taking them are assessed with a lower cutoff. A level above 4.0 ng/mL is generally considered abnormal, though some doctors use age-based cutoffs. PSA is not recommended for routine screening of the general population; men considering it should discuss risks and benefits with a doctor.
FAQ07
Prostadine questions people ask
What is a normal PSA level?
The NCI says a level above 4.0 ng/mL is generally considered abnormal, though some doctors use age-based cutoffs (NCI, PSA test). A number is read with your age, symptoms and history, so ask your doctor.
Do prostate supplements lower PSA?
Saw palmetto did not change PSA more than placebo in the sources we checked (MSK, Saw Palmetto). Finasteride and dutasteride, which are medicines, do lower PSA (NCI, PSA test). No evidence exists for Prostadine itself.
Should I get a PSA test?
It is an individual decision. The USPSTF advises discussing benefits and harms for men 55 to 69, and recommends against routine screening from age 70 (USPSTF, Prostate cancer screening). Your doctor can weigh your own risks.
Can an enlarged prostate raise PSA?
Yes. BPH and prostatitis can raise PSA without cancer being present (NCI, PSA test). That is why a raised PSA leads to further questions and not to a conclusion.
