Our two best sellers, built to work together. Save 15% vs buying separately.The Deep Sleep Stack pairs your daily foundation with your hard-night rescue: Utilix Night (Magnesium Glycinate) — taken every night. Rebuilds the mineral baseline your nervous system needs to switch off. This is the long game: deeper sleep that compounds week after week. Utilix Switch-Off (Advanced Sleep Complex) — taken on the nights you need it. L-theanine, GABA, 5-HTP and calming botanicals to take you from wired to asleep, fast. Most customers take Night every evening and keep Switch-Off on the nightstand for high-stress nights. Together they cover both halves of the sleep problem: the deficiency that makes sleep shallow, and the racing mind that stops it starting.What's in the box: 1 × Night (90 capsules) + 1 × Switch-Off (60 capsules). A full month of complete sleep support.30-day money-back guarantee on the whole stack. If your sleep hasn't improved in two weeks of consistent use, we refund everything.
