Not all forms of Nettle Root are equal. The form you choose determines how much Nettle Root actually reaches your tissues, and the difference between the best and worst forms can be substantial. This 4:1 Nettle root (Urtica dioica) extract concentrates the lectins, sterols, and polysaccharides associated with healthy SHBG binding and prostate function. Research supports concentrated nettle root extract for promoting healthy testosterone bioavailability and urinary comfort related to prostate health.

Nettle (Urtica dioica L.) Root Extract 4:1 Preferred (Preferred Form) has a bioavailability rating of good (S2). Typical dose range: not yet documented in our database.

Nettle root (Urtica dioica) 4:1 extract provides concentrated lignans and polysaccharides that support prostate health through multiple mechanisms — including SHBG binding modulation and 5-alpha-reductase inhibition. Clinical trials demonstrate benefits for urinary function and prostate comfort. Distinct from nettle leaf, the root targets hormonal and prostatic pathways specifically.
