What Is Prostadine? A Plain Description

Prostadine is a dietary supplement in liquid form. It comes in a small amber dropper bottle, and the front reads PROSTADINE with the words Prostate Complex underneath.

The bottle holds 2 fl oz, which is 60 mL. The seller's info page says to take 2 mL, or two droppers, once a day, so one bottle covers 30 days. It is sold online through a retailer's checkout, in packs of two, three or six bottles.

It is a supplement, which means it is not a prescription drug and does not go through the testing a medicine does before sale (FDA, Using Dietary Supplements). That single fact shapes everything else about the product: claims are the seller's, and checking them is up to the reader.

The seller says it supports prostate and urinary health, and ties the problem to hard water minerals.

That story is quoted and checked on our hard-water page. The short version is that the USGS calls hard water not a health concern but a nuisance (USGS, Hardness of Water), and the NIDDK says researchers have not linked diet or nutrition to causing an enlarged prostate (NIDDK, Enlarged Prostate (BPH)).

The research on single ingredients is thin for the prostate. Saw palmetto, the best studied, showed little or no benefit in a 2023 Cochrane review of 27 trials and 4,656 men (Cochrane review, saw palmetto 2023). The product itself has no published trial that we could find.

It is not a prostate medicine, and it is not a replacement for one.

• It does not shrink the prostate, and no source says it does.
• It is not approved by the FDA, as no supplement is approved before sale (FDA, Using Dietary Supplements).
• It is not a test for, or a treatment of, prostate cancer or infection.
• It is not a reason to skip a doctor when symptoms are new or getting worse.

A man who takes tamsulosin or finasteride should keep taking it. Both are prescribed for an enlarged prostate and are covered by drug information that supplements lack (MedlinePlus, Tamsulosin).
