Prostadine Ingredients Research Scorecard: Nine Lines, Graded
Of nine ingredients, only iodine has a firm role, and it is for the thyroid. Saw palmetto has the most prostate trials and they were mostly negative. The other seven have little or no human evidence for the claims made, and none has a printed amount. The scorecard shows each line.

The basics01
How is the scorecard graded?
Three plain questions, asked of each ingredient: what is the best human evidence for the prostate, what is the main caution and is the amount printed.
We use public sources first, such as Cochrane, NCCIH, the NIH and Memorial Sloan Kettering. We do not grade on traditional use, since that is a history and not a measurement.
A weak grade is not an accusation. It means the studies are missing, small or mixed. A strong grade for safety is not a strong grade for benefit, and the two should be read apart.
The evidence02
The scorecard
| Ingredient | Best human evidence for the prostate | Main caution | Amount printed |
|---|---|---|---|
| Nori | None found | Iodine content (NIH ODS, Iodine) | No |
| Wakame | None found | Iodine content | No |
| Kelp | None found | Very high iodine possible (ATA, Excess iodine) | No |
| Bladderwrack | Benefit not confirmed (MSK, Bladder wrack) | Iodine; metals | No |
| Saw palmetto | Little or no benefit in 27 trials (Cochrane review, saw palmetto 2023) | Bleeding case reports (MSK, Saw Palmetto) | No |
| Pomegranate | Conflicting PSA data (MSK, Pomegranate) | Warfarin case report | No |
| Iodine | None for the prostate | Thyroid effects (NIH ODS, Iodine) | No |
| Shilajit | One small testosterone trial (Pandit et al., Andrologia 2016) | Purity and metals | No |
| Neem | Studies lacking (MSK, Neem) | Oil poisoning (MSK, Neem) | No |
The numbers03
What does the table say overall?
Three things stand out. First, the evidence column is thin. Where trials exist, they are mostly negative for saw palmetto and mixed for pomegranate. Where nothing exists, the entry says so.
Second, the caution column is dominated by iodine. Five of nine lines are iodine sources, and thyroid effects are the best documented risk.
Third, the last column is empty. No ingredient has a printed amount, so none can be matched to a trial dose.
The catch04
Is anything encouraging?
Some points are reassuring. Saw palmetto appears well tolerated and did not change PSA more than placebo (NCCIH, Saw Palmetto)(MSK, Saw Palmetto). Pomegranate is generally well tolerated. Nori and wakame are ordinary foods in modest amounts. None of these is a reason to fear the bottle.
The honest summary is balanced: low evidence of benefit, a few real cautions, and a label that hides its dose. That is a reason for care, not alarm.
Safety05
How to use the scorecard
Print it, or save a screenshot, and take it to your doctor or pharmacist. Circle the lines that matter for you: iodine if you have thyroid disease, saw palmetto and pomegranate if you take a blood thinner, neem if you take several medicines.

What to do06
How does this compare with a typical herbal formula?
A typical single-herb product has one or two trials behind it, and a label that gives the extract and dose. A multi-ingredient formula usually has a trial for none of its own and borrows results from single ingredients, which is a weaker argument because ingredients can interact and doses differ.
Prostadine follows the second pattern. The seller borrows the reputation of nine names, and the research on each is thin. The scorecard makes that visible in one glance.
It is also a reminder that more ingredients is not more evidence. Each added line is another source of caution, another question for a pharmacist and another amount to check.
On the label07
Will the scorecard change?
It should, if the seller supplies amounts or a trial appears. We will update the entries and date the change. A published trial of the finished product, or a lab report with amounts, would move several lines at once, and we would be glad to report it.
FAQ08
Prostadine questions people ask
Which Prostadine ingredient has the best evidence?
Iodine has a firm role, but for the thyroid, not the prostate. For the prostate, saw palmetto has the most trials, and a 2023 review found little or no benefit.
Which ingredient raises the biggest safety question?
Iodine, because five of nine lines supply it and the amount is unknown. Thyroid disease, thyroid medicine and pregnancy are the main reasons to ask a doctor.
Is any ingredient proven for the prostate?
Not in the sources we hold. Evidence is negative or mixed for saw palmetto and pomegranate, and absent for the rest.
Where can I read about each ingredient?
Our ingredients page links to a profile of each one, with the sources and the amounts that studies used.
