Seaweed extract shown to relieve prostate symptoms

In a breakthrough clinical trial undertaken by Australian biotechnology company Marinova, a unique seaweed extract has been shown to relieve the symptoms of benign prostatic hyperplasia (BPH). HOBART, Australia , July 27, 2026 -- A randomised, double-blind, placebo-controlled clinical trial evaluated the effects of fucoidan, a naturally occurring compound found in brown seaweed, on men with BPH (prostate enlargement). BPH is a common health issue for men across the globe. Worldwide estimates place prevalence at 50-60% of men in their 60s, increasing to 90% of men in their 80s. While it is typically not life-threatening, urinary symptoms including difficulty passing urine, a weak stream and an increase in the frequency of urination often result in a significant reduction in quality-of-life.
