Safety, Cautions & Contraindications

Safety note[12, 13]Caution

Generally well tolerated; mild gastrointestinal upset is the most common effect. BPH must be medically diagnosed (to exclude prostate cancer), and because the best evidence does not show benefit, saw palmetto should not replace proven treatment.

Safety note[12]Caution

Has mild anti-androgen and antiplatelet effects, so use caution with anticoagulant medicines and before surgery; avoid in pregnancy (hormonal activity).
