The Unnamed Harvard Study on Hard Water and the Prostate
The info page points to a recent Harvard study on hard water and the prostate, with no authors, journal or year. Without those, nobody can find it. The USGS calls hardness not a health concern but a nuisance, and the NIDDK says the cause of BPH is not fully known and diet is not linked.

The basics01
What does the page say?
It says that a recent Harvard study drew attention to hard water in the United States, and ties minerals in water to prostate problems.
The page gives no authors, no journal, no year and no title. A reader who wants to read the paper cannot, because the page does not say which one it means.
A university name is a strong trust cue. It is also easy to use without a link, since few visitors will search for the study.
The evidence02
What can be checked
| Item | Given | Needed |
|---|---|---|
| Authors | None | Names to search |
| Journal and year | None | To locate the paper |
| Title | None | To confirm the topic |
| Study type | None | Human, animal or lab; observational or trial |
| Link | None | A DOI or PubMed entry |
With none of the five, the claim cannot be tested, so it can only be held as unverified.
The numbers03
What do public sources say about hard water?
The USGS describes hardness as mainly dissolved calcium and magnesium, with bands from soft to very hard, and says it is not a health concern but can be a nuisance, causing soap scum and scale in pipes. Drinking water can also contribute calcium and magnesium to the diet (USGS, Hardness of Water).
So the main public source on hardness does not link it to disease. It treats it as a household matter.
The catch04
What do they say about the cause of an enlarged prostate?
The NIDDK says scientists do not fully know why BPH occurs, that aging and hormone changes are suspected, and that researchers have not linked diet or nutrition to causing or preventing it (NIDDK, Enlarged Prostate (BPH)).
That does not rule out a future finding. It does mean that a claim of a real root cause, found and settled, goes beyond what the main public source states today. A study that shows an association, if one exists, would still not prove cause.
Safety05
What about kidney stones?
People sometimes mix hard water with kidney stones, since both involve minerals. The NIDDK page on stones explains that stones form when certain minerals reach high levels in urine, advises drinking plenty of water and adjusting sodium, animal protein, calcium and oxalate, and does not mention hard water (NIDDK, Kidney Stones). The stones story is not the prostate story, and neither supports a hard water root cause for BPH.
What to do06
What would a real water and prostate study need to show?
It would need a population, a measure of water hardness at home, a measure of prostate outcome such as BPH diagnosis or symptom score, and a way to adjust for age, diet, smoking, weight and region. Even then, an association would show that two things travel together, not that one causes the other.
It would need to be repeated, ideally by different teams in different places, before anyone could say a root cause had been found. The NIDDK notes that scientists do not fully know why BPH occurs, and that suspects include aging and hormone changes (NIDDK, Enlarged Prostate (BPH)). That is the state of knowledge a good study would add to, not overturn in a headline.
It is fine for a seller to mention a study. It is not fine to rest a root cause claim on one that cannot be named.
On the label07
Being fair to the claim
We cannot say no such study exists. Many papers study water and health, and one might touch on this. We say only that the page does not identify it, so the claim cannot be checked, and that the public sources we can read do not support the idea.
If the seller names the study, we will read it, summarise what it did and did not show and update this post. Send it through the contact page.

Where to read more
Our hard water claim page goes through the full story step by step, and the legit check shows how to test any page that cites an unnamed source.
FAQ09
Prostadine questions people ask
Which Harvard study does Prostadine cite?
The info page does not say. It gives no authors, journal, year or title, so the study cannot be found or checked from the page.
Is hard water a proven cause of prostate trouble?
The sources we hold do not say so. The USGS calls hardness a nuisance, not a health concern, and the NIDDK says diet and nutrition are not linked to BPH.
Can an unnamed study ever be reliable?
It cannot be checked, so it should not carry weight. A citation with authors, journal, year and a link lets anyone read what was actually found.
What if the study exists?
Then the seller can name it. We will read it, say what kind of study it was and whether it supports the claim, and update our pages.
