Nettle root

Also known as Stinging nettle / Urtica dioica
BEVIDENCE

The sting is the famous part. The root is the useful one.

The honest take
Nettle root is the quiet one in every prostate formula — rarely the headline, almost always present. The evidence is decent for a botanical: randomised trials at 300–600 mg of root extract show real improvement in urinary symptom scores. Ours are lower — 50 mg in PROSTATE, and a share of the botanical blend in PRIME — which puts it in the formula as a supporting ingredient, not as the trial dose. Worth knowing the other trap: most of what is sold as 'nettle' is leaf, which is a different ingredient with a different literature. If a label does not say root, assume it is not.
What it is
Extract of the root of the stinging nettle — the same plant as the leaf that gets you on a walk, but a different part of it and a different ingredient entirely.
How it works
Nettle root carries lignans and sterols studied for their interaction with sex-hormone-binding globulin and with the enzyme pathways active in prostate tissue. The mechanism is plausible and partly mapped; the clinical effect, where it shows up, is modest.
What it does
Used to support normal prostate and urinary wellness, usually alongside the other botanicals in the category rather than alone.
Who it's for
Men on adult-maintenance duty, particularly alongside saw palmetto and pygeum, which is how the trials tend to use it. Not for anyone treating diagnosed symptoms on their own.
How to use it
Daily with food, inside PROSTATE or PRIME. Judged over months alongside the rest of the stack, never on its own.
What to expect
Support rather than an event. In the trials that found an effect, symptom scores improved gradually over 8–12 weeks; nobody described a switch flipping.
The research
Grade B for root extract at trial doses, including a double-blind study in 100 men and a larger series reporting improved symptom scores. Weaker, and much more mixed, below those amounts. Leaf preparations are a separate literature and should not be read across.

Read the labelNot a treatment for any prostate condition. Root and leaf are different ingredients with different uses — check which one a label means. Speak to a doctor first if you take blood-pressure or diuretic medication.

Evidence grades describe how well an ingredient is studied — A well-supported, C emerging — not a promise of results. Educational, not medical advice. Doses are typical ranges; follow the label on the product.
