Quick verdict: Prostadine is a liquid supplement taken as two droppers each morning, mixing four seaweeds with saw palmetto, pomegranate, iodine, shilajit and neem. It carries a 60-day refund policy. People with thyroid conditions should ask a doctor first.

Why Prostadine is different from most prostate supplements

Most products in this category are capsules built around saw palmetto, pygeum and nettle. Prostadine takes another route: it is a liquid, and its formula leans heavily on sea vegetables and added iodine. That makes it a distinct option for men who dislike pills, and it also creates a specific safety question that capsule formulas do not raise.

How Prostadine is taken

According to the official website, the serving is two full droppers (2 ml) per day, preferably in the morning. The sales page does not state how many servings a bottle holds in its text, though bundle names suggest one bottle is meant to last about a month.

The nine Prostadine ingredients named on the official site

No amounts are listed in the page text, including for iodine.

The iodine question in Prostadine

Iodine is an essential nutrient, but more is not better. The NIH Office of Dietary Supplements sets the adult recommended intake at 150 mcg a day and the upper limit at 1,100 mcg. It also notes that:

• seaweeds vary enormously in iodine content, so kelp-type products can be unpredictable;
• people with autoimmune thyroid disease may react to amounts that are safe for others;
• excess iodine can trigger thyroid problems, including both underactive and overactive thyroid;
• iodine supplements can interact with antithyroid medicines and with some blood pressure drugs (ACE inhibitors, potassium-sparing diuretics).

Because Prostadine combines added iodine with four seaweeds and does not publish amounts, anyone with a thyroid condition, or anyone already taking a multivitamin with iodine, should review it with a doctor.

What research says about the other Prostadine ingredients

Saw palmetto: a 2023 review of 27 studies, summarized by NCCIH, found little or no benefit for BPH urinary symptoms when taken alone. More in our saw palmetto guide.

Pomegranate: studied mainly in men with prostate cancer, where the National Cancer Institute describes results as mixed. NCCIH considers pomegranate juice and extract likely safe for most people.

Shilajit: human studies are small and mostly unrelated to the prostate (PubMed). Quality varies, and raw or poorly purified shilajit can contain heavy metals, so sourcing matters.

Neem and seaweeds: we found little human research linking them to prostate health.

No independent clinical trial of the Prostadine formula itself turned up in our search.

Prostadine price and shipping

Prostadine refund policy in detail

The sales page promises a 60-day money-back guarantee. The separate refund policy adds the conditions:

• the 60 days start on the delivery date shown by the carrier;
• you email support with "Refund Request" in the subject line;
• you send back all bottles, opened, unopened or empty, with the packing slip, to an address in Ohio;
• the buyer pays return shipping;
• refunds can take 5 to 10 days to appear after processing.

The policy also suggests using the product for at least three months, which is longer than the refund window. Keep that in mind: if you want a refund, you must act inside the 60 days.

A Prostadine label checklist

If you are seriously considering Prostadine, ask the company for the full Supplement Facts panel and look for:

• the iodine amount per 2 ml serving, so you can add it to any iodine from multivitamins or iodized salt;
• the amount of each seaweed, since seaweeds carry their own iodine;
• the shilajit source and whether it is purified and tested for heavy metals;
• the number of servings per bottle;
• any alcohol or preservatives used in the liquid base.

Who should avoid Prostadine or talk to a doctor first

• People with thyroid disease or on thyroid medication.
• People on ACE inhibitors or potassium-sparing diuretics.
• Anyone with kidney disease.
• Men with a prostate cancer diagnosis or an abnormal PSA.
• Anyone under 18.

And for everyone: urinary symptoms need a medical evaluation first. Our guide on when to see a doctor explains which symptoms are urgent.
