Product details
Serenexin™ is a breakthrough brain-to-gut supplement featuring Digexin, the clinically studied ingredient designed to deliver fast GI relief while supporting the gut-brain connection. It helps reduce constipation, improve digestion and regularity, while also lowering stress and anxiety, boosting serotonin, and enhancing sleep quality for better overall wellness.*
Serenexin™ works through the brain-gut axis. It doesn’t just act directly on the gut — it also sends calming, pro-digestion signals from the brain for substantial GI improvements. Clinically shown to reduce constipation symptoms by up to 98%, speed digestion, and reduce reflux, bloating, and indigestion.*
The formula features a proprietary blend of Withania somnifera (ashwagandha) root and Abelmoschus esculentus (okra) fruit extracts in a vegetarian, hypoallergenic capsule.
