The most-studied botanical for the aging prostate, included here for the DHT pathway.
Saw Palmetto Berries come from Serenoa repens, a small palm native to the southeastern United States, and it's the most-studied botanical for the aging prostate.
Included for the DHT pathway rather than testosterone — it's studied for its interaction with 5-alpha-reductase, the enzyme that converts testosterone to DHT.
The largest clinical trials found Saw Palmetto no better than placebo for urinary symptoms specifically, though it remains widely used and studied for prostate comfort.
This describes general research on Saw Palmetto Berries itself, not the finished Primordial Vigor X product, which hasn't been the subject of its own clinical trial. See the full ingredients list or the formula overview for more.
