Perika (R) St. John’s Wort

Perika (R) Difference The patented Perika extract (WS (R) 5570) is standardized to hyperforin – one of the key “mood enhancing” actives found in St. John’s Wort.* HyperiSure (R) 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 potency.
