About Muira Puama Root (Ptychopetalum olacoides)
Muira puama is an Amazonian shrub traditionally used as an aphrodisiac/tonic. A small randomized, double-blind trial (n=30) found 1,200 mg/day improved IIEF erectile-function scores versus placebo over 12 weeks, and small open-label reports describe libido improvements at 1,000-1,500 mg/day. Evidence base is thin — small sample sizes, limited independent replication, and safety data are sparse.
What Muira Puama Root (Ptychopetalum olacoides) supports
- May support libido/erectile function — based on one small RCT (n=30) and small open-label reports, not a robust evidence base
