If you're dealing with age-related prostate concerns and urinary comfort, this formula delivers 600mg of **Mixed Phytosterols** including 250mg of beta-sitosterol, a plant compound with moderate clinical backing. Multiple studies use beta-sitosterol at 60–130mg daily, so the 250mg dose here gives you meaningful coverage across two caplets.
The mineral profile adds supporting players: **Zinc** at 15mg is right at the clinical threshold for prostate-relevant research, and **Vitamin D3** at 800 IU contributes to your baseline D status. **Boron** at 3mg matches the dose studied for hormonal and bone support. **Selenium** at 70mcg falls short of the 100–200mcg range used in most studies.
The zinc is provided as zinc oxide, which is the least-absorbed supplemental form. For a product built around prostate health where zinc matters, that's a notable compromise in your absorption efficiency.
