All 8 Ingredients, Explained

Eight ingredients, eight stated doses. Here's what each one in Prosta Defender's formula is actually there for, without inflating any single one's evidence base beyond what it supports.

Saw Palmetto Extract — 320mg

The most-studied ingredient in this category. Saw Palmetto's liposterolic extract works by inhibiting the 5-alpha reductase enzyme, directly reducing conversion to DHT, the hormone byproduct most closely tied to prostate enlargement.

Beta-Sitosterol — 300mg

A plant sterol with research specifically connecting it to improved urinary symptom scores and more complete bladder emptying at this dosing level.

Pygeum Africanum — 100mg

African cherry bark extract, standardized to 12-13% triterpene content, targeting inflammation and bladder-neck muscle tone — the mechanism most tied to sudden urgency.

Pumpkin Seed Extract — 250mg

Provides zinc, fatty acids and phytosterols supporting the detrusor muscle, the one responsible for actually emptying the bladder rather than urine flow alone.

Zinc — 15mg

An essential mineral in bioavailable zinc picolinate form, supporting testosterone metabolism and immune function specifically in prostate tissue.

Lycopene — 10mg

A carotenoid antioxidant protecting prostate cells from oxidative stress, with research connecting it to healthy PSA levels.

Nettle Root — 200mg

Urtica dioica extract that binds to sex hormone binding globulin, reducing free testosterone conversion to DHT through a separate pathway from Saw Palmetto.

Selenium — 70mcg

A trace mineral in selenium methionine form, supporting glutathione peroxidase enzyme activity for cellular protection against free-radical damage.
