faq

day–guard combines clinically backed ingredients that help your body break down acetaldehyde (a toxic alcohol byproduct), replenish key nutrients, and reduce inflammation. Think of it as nutritional insurance for when you drink.

day–guard is built around four functional pillars:


  • Liver Support: DHM, Milk Thistle, Turmeric, L–Cysteine
  • Electrolytes: Magnesium, Sodium
  • Vitamins: B1, B2, B3, B6
  • Gut Health: Pear, Ginger, Xylitol, Prebiotics

Electrolytes help with hydration, but that’s only a small part of why you feel rough the next day. Hydration alone doesn’t protect your liver or gut, the systems most affected by alcohol.

day–guard is packed with electrolytes and goes beyond simple rehydration. It also supports your body’s natural detox process, replenishes lost nutrients, and protects your liver and gut health so you wake up feeling genuinely better, not just less thirsty.

Yes. day–guard supports your liver and gut with ingredients like DHM (from Oriental Raisin Tree), Milk Thistle, L–Cysteine, and Ginger to help your body process alcohol more efficiently and recover faster.

No. day–guard will not prevent intoxication or enhance sobriety. It simply supports your body’s natural detox and recovery process.*

Take one stick right before or during drinking and another for every 3–5 drinks.

Absolutely. Many people take day–guard for general liver, gut, and nutrient support—even on days they don’t drink.

Yes. Most people take one before drinking and, optionally, another for every 3–5 drinks. All ingredients are within safe daily limits for adults.

Nope! Each stick is a ready–to–eat jelly — no water or mixing required. Just tear and enjoy.

Like all dietary supplements, day–guard is not FDA–approved to treat or prevent disease, but it’s manufactured in FDA–registered, GMP–certified facilities and tested for quality and safety.

day–guard is made in Korea by a pharmaceutical partner founded in 1963, bringing over 60 years of clinical expertise as one of the largest and most trusted manufacturers in Korea.
