What is an optimal PSA (Prostate-Specific Antigen) level?
The short answer
Optimal PSA (Prostate-Specific Antigen) is under 2 ng/mL, as stated on video.
Most labs call PSA (Prostate-Specific Antigen) high only above 4. So your report can call 3 normal while it sits above the optimal ceiling.
These numbers are for men.
“you should be really low like it should be less than two nanograms per milliliter now the reference range goes up to four uh but individuals with levels below four can still have prostate cancer so it's important to to look at the progression of Rise”
“if your PSA is below two the probability you have a lethal prostate cancer is, you know, less than one in a million, so we don't have to worry about that individual”
What each range means
- under 2 ng/mL Optimal
- 2–4 ng/mL Normal on most reports. Above optimal“if your PSA is below two the probability you have a lethal prostate cancer is, you know, less than one in a million, so we don't have to worry about that individual” Dr. Ted Schaeffer · 5:43 →
- over 4 ng/mL Most labs flag this as high
What PSA (Prostate-Specific Antigen) measures
A protein your prostate makes.
It rises with prostate enlargement, inflammation and cancer. So it is where an investigation starts, not where it ends.

Common questions
What is an optimal PSA (Prostate-Specific Antigen) level?
Under 2 ng/mL, from a quote on video (Dr. Mark Hyman, 13:58).
What is a normal PSA (Prostate-Specific Antigen) level?
Most US labs print 0–4 ng/mL. Your report grades you against that range. It exists to catch disease, not to describe your best.
What does your PSA (Prostate-Specific Antigen) number mean?
On a typical lab range, up to 4 ng/mL is normal and over 4 is high. Your own report prints its range next to your number, and that is the one your lab uses. The optimal range on this page comes with the quote behind it.
Is PSA (Prostate-Specific Antigen) of 3 normal?
A typical lab range calls it normal. On video, the optimal ceiling is 2 ng/mL (Dr. Mark Hyman, 13:58), so by that line it is high.
What does the PSA (Prostate-Specific Antigen) test measure?
A protein your prostate makes. It rises with prostate enlargement, inflammation and cancer. So it is where an investigation starts, not where it ends.
