Nutrition21 unveils EverZen, which has been clinically shown to promote a positive mood and healthy response to occasional stress. The new functional ingredient contains a novel plant bioactive, 6-methoxy-2-benzoxazolinone (6-MBOA), a naturally occurring metabolite that protects plants from environmental stressors as they grow, such as insects, fungi, and bacteria.According to the company, the bioactive may offer similar protective benefits to humans. The company, part of Everwell Health Holdings, highlights that two clinical studies back the premium, patent-pending ingredient. The extract is harvested from young non-GMO corn plant (Zea mays) leaves and is standardized to a specific 6-MBOA concentration.
