The patented Perika extract (WS® 5570) is standardized to hyperforin - one of the key “mood enhancing” actives found in St. John’s Wort.*
HyperiSure® System Stabilizing Technology
Hyperforin is rather unstable and can lose potency over time. However, using our proprietary HyperiSure System stabilizing technology, Perika delivers a guaranteed level of hyperforin for optimal effectiveness.
