Dayguard

Day-Guard is a consumer health and wellness brand offering doctor-formulated dietary supplement products designed to support liver function, gut health, hydration, and vitamin replenishment in individuals who consume alcohol. The company's flagship product is a pre-alcohol vitamin jelly stick, a ready-to-eat functional supplement that requires no mixing or water and is designed to be taken before or during drinking. The formulation is physician-developed and draws on clinically studied ingredients across four functional categories: liver support (dihydromyricetin/DHM, milk thistle, turmeric, and L-cysteine), gut health (pear extract, ginger, prebiotics, and xylitol), B-vitamin replenishment (vitamins B1, B2, B3, and B6), and electrolyte hydration (magnesium and sodium). The product is positioned as a comprehensive alcohol-aid supplement that targets acetaldehyde metabolism, nutrient depletion, inflammation, and gastrointestinal integrity — mechanisms commonly associated with the adverse after-effects of alcohol consumption. Day-Guard differentiates itself in the hangover-aid and alcohol-support supplement category by combining multiple functional ingredient pillars into a single, portable jelly-stick format, making it convenient for on-the-go use. The brand markets to adult consumers in the United States and emphasizes its Korean pharmaceutical manufacturing heritage, having partnered with a Korean pharmaceutical company founded in 1963 with over six decades of clinical and manufacturing expertise. Products are manufactured in FDA-registered, GMP-certified facilities, providing a level of quality assurance consistent with pharmaceutical-grade supplement production. The brand reports a customer base exceeding 20,000 and highlights endorsement from medical advisors. It positions itself as the number-one doctor-recommended alcohol-aid brand and has received coverage in consumer press for bringing Korean wellness culture to the American market. Products are sold direct-to-consumer via subscription and single-purchase options, with free shipping on subscription orders and a 30-day money-back guarantee.
