From the archived source record

Simply take 2 tablets 30 minutes before drinking and you’ll be able to drink a 2-3 beers without noticing any intoxication.” Dycetin FAQ page: • “Dycetin is a natural scientifically proven hangover prevention supplement that blocks the affect alcohol has on the brain and allows the liver to process alcohol more quickly. It does this both by blocking alcohol’s effect on the brain’s GABA receptors and by allowing the liver to clear alcohol and its toxic byproduct acetaldehyde from the body at a much faster rate than normal. Combined, these effects allow Dycetin to prevent hangovers and reduce feelings of alcohol intoxication.” • “To prevent a hangover, take 2 tablets of Dycetin before bed with a large glass of water.” Your website [see original source] also contains evidence of intended use in the form of personal testimonials recommending or describing the use of Dycetin for the cure, mitigation, treatment, or prevention of disease. A hangover is a sign or symptom of alcohol intoxication, a disease. Like all poisonings, alcohol intoxication causes dose-related dysfunctioning and damage, ranging from mild impairments to death. Alcohol intoxication causes temporary damage to brain function, causing impairments of judgment, attention, reflexes, and coordination. Therefore, alcohol intoxication meets the definition of disease in 21 CFR 101.93(g)(1) [see 65 Fed.
