In other words, only St. John's Wort extracts with significant amounts of hyperforin are effective. This fact was confirmed by a clinical trial, involving 147 patients with depression, which compared placebo to two different St. John's Wort extracts with varying amounts of hyperforin. One extract contained only 0.5% hyperforin, the concentration found in most brands sold in the United States. The other extract was standardized to provide 5% hyperforin, the clinically-proven potency found in AMORYN and pharmaceutical-grade European St. John's Wort. (Aside from hyperforin content, the two extracts were identical. Both extracts were standardized to contain 0.3% hypericin, the compound previously thought to be the active constituent in SJW.) The 5% extract was found to effectively relieve depression, but the 0.5% was ineffective and performed no better than placebo.6 This study demonstrates the importance of choosing a St. John's Wort extract that, like AMORYN's, is standardized to contain a high concentration of hyperforin. An extensive body of research, consisting of over 30 controlled clinical trials, proves the effectiveness of hyperforin-rich St. John's Wort extract for relieving depression.2,7,8,9,10 Because most studies used extracts containing at least 3% hyperforin, this research does not apply to SJW extracts without a standardized quantity of hyperforin (such as those commonly sold "over-the-counter" in the United States). In fact, a recent study found that hyperforin, in high daily doses, is superior to the prescription drug paroxetine (Paxil®) as a treatment for even severe depression.11 Furthermore, clinical research suggests that adverse side effects occur less frequently with hyperforin than prescription antidepressants.7,9 For instance, although hyperforin was shown to relieve severe depression at least as well as Paxil®, patients taking hyperforin reported 42% fewer side effects.11 And hyperforin rarely causes weight gain or sexual dysfunction, side effects common with popular prescription drugs. Few natural remedies are backed by as much scientific evidence as hyperforin, so please feel free to review the clinical research for yourself. Unfortunately, few St. John's wort products contain a standardized amount of hyperforin. You never know what you're getting when you buy a SJW product off the shelf. While some brands contain enough hyperforin to improve mood, most contain little or none. In fact, a recent study tested eight brands sold in the United States and found that only two contained more than 1% hyperforin. In other words, high-quality SJW extracts are proven to be an effective treatment for depression and anxiety, but most SJW products on the market are virtually worthless because they contain very little hyperforin. This fact motivated the scientists at BioNeurix Corporation to develop AMORYN. AMORYN contains the highest quality St. John's wort extract in the world, standardized to 3-5% hyperforin. AMORYN's pharmaceutical-grade SJW extract is the same one prescribed in Europe for depression and used by researchers in clinical trials. Each dose (two capsules) of "potency assured" AMORYN contains 36mg of hyperforin (from 1200mg of St. John's wort extract with at least 3% hyperforin), so you can be sure that you're receiving the optimal amount. The graph below shows the results of AMORYN's high hyperforin content and industry-leading quality-control standards: More than three out of four AMORYN users say that AMORYN is superior to other products containing St. John's Wort. Order AMORYN now to harness the healing potential of hyperforin.
