What is Prostastream?
ProstaStream is a capsule supplement marketed for prostate health. The official page names saw palmetto, maitake, reishi, shiitake, graviola, cat's claw, pygeum africanum bark and stinging nettle root, and says there are "many more" ingredients without publishing the full list or per-ingredient doses. The single bottle is $69 and the vendor states a 60-day money-back guarantee.

Our verdict process
This review was generated from fixed data rules — the same rules behind our published methodology. We verify prices, refunds, ingredient disclosures and red flags against the official page; nothing is judged by hand.

About this reviewer →What this review measures
This page is the analysis layer: it explains what the documented data means for Prostastream and where the verdict comes from. The product page is the data sheet (price history, captured reviews, affiliate link); this review focuses on the score components and the commercial signals behind them. Nothing here is a claim that the product works for weight loss, memory, vision or any other outcome. The current SiftScore is 62.8/100, built from: Value 80.0, Trust 55.0, Evidence 40.0, Market 50.0, Transparency 90.0.
What the documented data shows
Documented fields at the time of this review: price $69.00, refund 60 days, 8 named ingredients, and 1 red flag. The flags are: exaggerated-claims. A published price and refund window are transparency signals, not proof of efficacy. A missing ingredient panel or dose is recorded as unknown, not guessed.
What would change this verdict
The verdict would change if Prostastream publishes per-ingredient doses, adds or removes a red flag, changes its refund window or price, or links a product-specific trial. The score is recomputed after each data refresh, and the review follows the data rather than a fixed editorial opinion. If a value no longer matches the official page, report it and we will verify it against the source.
What we do not treat as evidence
What we do not treat as evidence: marketing claims, before-and-after photos, fake countdowns, or a reference list that is not tied to the finished product. Those can be recorded as red flags, but they do not raise the score or prove efficacy. A product can have clean commercial terms and still lack evidence that it works; the score measures disclosure, not outcomes.
Safety and limits
This review does not tell you whether Prostastream is safe for you, whether it will work, or how it interacts with your medication. Reviews from the vendor page are customer statements, not clinical evidence. Use the product page for the full safety notes, the methodology page for the formula, and a qualified professional for personal medical advice.
