We tested NSP Kava Kava against three popular brands, measuring the amount of kavalactones (the key active component) per capsule. Our test showed that NSP Kava Kava had the highest number of kavalactones per capsule.
What’s more important, NSP Kava Kava was the only one of these products that actually contained the amount of kavalactones indicated on the label. Others fell short, as much as 48 percent! It’s just one more reason to put your confidence in NSP products.
